# Custom SSO

Set up custom Single Sign-On (SSO) authentication for Fireworks AI

Fireworks uses single sign-on (SSO) as the primary mechanism to authenticate with the platform.
By default, Fireworks supports Google SSO.

If you have an enterprise account, Fireworks supports bringing your own identity provider using:

*   OpenID Connect (OIDC) provider
*   SAML 2.0 provider

<Info>
  Coordinate with your Fireworks AI representative to enable the integration.
</Info>

## OpenID Connect (OIDC) provider

<Steps>
  <Step title="Create OIDC client application">
    Create an OIDC client application in your identity provider, e.g. Okta.
  </Step>

  <Step title="Configure client">
    Ensure the client is configured for "code authorization" of the "web" type (i.e. with a client\_secret).
  </Step>

  <Step title="Set redirect URL">
    Set the client's "allowed redirect URL" to the URL provided by Fireworks. It looks like:

    ```
    https://fireworks-<your-company-name>.auth.us-west-2.amazoncognito.com/oauth2/idpresponse
    ```
  </Step>

  <Step title="Note down client details">
    Note down the `issuer`, `client_id`, and `client_secret` for the newly created client. You will need to provide this to your Fireworks.ai representative to complete your account set up.
  </Step>
</Steps>

## SAML 2.0 provider

<Steps>
  <Step title="Create SAML 2.0 application">
    Create a SAML 2.0 application in your identity provider, e.g. [Okta](https://help.okta.com/en-us/Content/Topics/Apps/Apps_App_Integration_Wizard_SAML.htm).
  </Step>

  <Step title="Set SSO URL">
    Set the SSO URL to the URL provided by Fireworks. It looks like:

    ```
    https://fireworks-<your-company-name>.auth.us-west-2.amazoncognito.com/saml2/idpresponse
    ```
  </Step>

  <Step title="Configure Audience URI">
    Configure the Audience URI (SP Entity ID) as provided by Fireworks. It looks like:

    ```
    urn:amazon:cognito:sp:<some-unique-identifier>
    ```
  </Step>

  <Step title="Create Attribute Statement">
    Create an Attribute Statement with the name:

    ```
    http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress
    ```

    and the value `user.email`
  </Step>

  <Step title="Keep default settings">
    Leave the rest of the settings as defaults.
  </Step>

  <Step title="Note down metadata URL">
    Note down the "metadata url" for your newly created application. You will need to provide this to your Fireworks AI representative to complete your account set up.
  </Step>
</Steps>

## Troubleshooting

### Invalid samlResponse or relayState from identity provider

This error occurs if you are trying to use identity provider (IdP) initiated login. Fireworks currently only supports
service provider (SP) initiated login.

See [Understanding SAML](https://developer.okta.com/docs/concepts/saml/#understand-sp-initiated-sign-in-flow) for an
in-depth explanation.

### Required String parameter 'RelayState' is not present

See above.


# Managing users

Add and delete additional users in your Fireworks account

Only admin users can manage other users within the account.

## Adding users

To add a new user to your Fireworks account, run the following command:

```bash
firectl create user --email="alice@example.com"
```

To create another admin user, pass the `--role=admin` flag:

```bash
firectl create user --email="alice@example.com" --role=admin
```

## Updating a user's role

To update a user's role, run

```bash
firectl update user <USER_ID> --role="{admin,user}"
```

## Deleting users

You can remove a user from your account by running:

```bash
firectl delete user <USER_ID>
```


# Align transcription

If you need deployments in a non-GA region, please contact our team at [inquiries@fireworks.ai](mailto:inquiries@fireworks.ai).

## Using a region

When creating a deployment, you can pass the `--region` flag:

```
firectl create deployment accounts/fireworks/models/llama-v3p1-8b-instruct \
    --region US_IOWA_1
```

## Changing regions

Updating a region for a deployment in-place is currently not supported. To move a deployment between regions, please
create a new deployment in the new region, then delete the old deployment.

## Quotas

Each region has it's own separate quota for each hardware type. To view your current quotas, run

```
firectl list quotas
```


# Reserved capacity



Enterprise accounts can purchase reserved capacity, typically with 1 year commitments. Reserved capacity has the
following advantages over [on-demand deployments](/guides/ondemand-deployments):

*   Guaranteed capacity
*   Higher quotas
*   Lower GPU-hour prices
*   Pre-GA access to newer regions
*   Pre-GA access to newest hardware

## Purchasing or renewing a reservation

To purchase a reservation or increase the size or duration of an existing reservation, contact your Fireworks account
manager. If you are a new, prospective customer, please reach out to our [sales team](https://fireworks.ai/company/contact-us).

## Viewing your reservations

To view your existing reservations, run:

```
firectl list reservations
```

## Usage and billing

Reservations are automatically "consumed" when you create deployments that the meet the reservation parameters. For
example, suppose you have a reservation for 12 H100 GPUs and create two deployments, each using 8 H100 GPUs. While both
deployments are running, 12 H100s will count towards using your reservation, while the excess 4 H100s will be metered
and billed at the on-demand rate.

When a reservation approaches its end time, ensure that you either renew your reservation or turn down a corresponding
number of deployments, otherwise you may be billed at for your usage at on-demand rates.

Reservations are invoiced separately from your on-demand usage, at a frequency determined by your reservation contract
(e.g. monthly, quarterly, or yearly).

<Note>Reserved capacity will always be billed until the reservation ends, regardless of whether the reservation is
actively used.</Note>


# Account setup & management

Solutions for common account access issues and management procedures for Fireworks.ai accounts

## Multiple account access

**Q: What should I do if I can't access my company account after being invited when I already have a personal account?**

# Billing management

Information about Fireworks.ai invoicing and API billing.

## Invoice questions

**Q: Why did I receive an invoice when I only deposited credits?**

Fireworks.ai billing works as follows:

*   **Deposited credits** are used first.
*   Once credits are exhausted, you **continue to accrue charges** for additional usage.
*   **Usage charges** are billed at the end of each month.
*   You’ll receive an invoice for any usage that **exceeded your pre-purchased credits**.

This process happens automatically, regardless of subscription status. To prevent additional charges, please monitor your usage or contact support to set up spending restrictions.

***

## API billing

**Q: Are calls to the Models API billable?**

No, calls to the **Models API** endpoint are free. This applies to all **management API calls** for:

*   Accounts
*   Users
*   Models
*   Datasets

*Note*: While the API calls themselves are free, charges apply for:

*   **Model deployments**
*   **Fine-tuning jobs**

# Credit system

Understanding how Fireworks.ai billing, credits, and account suspension work.

## Billing and credit usage

**Q: How does billing and credit usage work?**

Usage and billing operate through a **tiered system**:

*   Each **tier** has a monthly usage limit, regardless of available credits.
*   Once you reach your tier's limit, **service will be suspended** even if you have remaining credits.
*   **Usage limits** reset at the beginning of each month.
*   Pre-purchased credits do not prevent additional charges once the limit is exceeded.

***

## Account suspension

**Q: Why might my account be suspended even with remaining credits?**

Your account may be suspended due to several factors:

1.  **Monthly usage limits**:
    *   Each tier includes a monthly usage limit, independent of any credits.
    *   Once you reach this limit, your service will be suspended, even if you have credits remaining.
    *   Usage limits automatically reset at the beginning of each month.

2.  **Billing structure**:
    *   Pre-purchased credits do not prevent additional charges.
    *   You can exceed your pre-purchased credits and will be billed for any usage beyond that limit.
    *   **Example**: If you have `$20` in pre-purchased credits but incur `$83` in usage, you will be billed for the `$63` difference.

***

## Missing credits

**Q: I bought credits but don’t see them reflected in my account. Did they disappear?**

Fireworks operates with a **postpaid billing** system where:

*   **Prepaid credits** are instantly applied to any outstanding balance.
*   **Example**: If you had a `$750` outstanding bill and added `$500` in credits, your bill would reduce to `$250`, with \$0 remaining credits available for new usage.

To check your credit balance:

1.  Visit your **billing dashboard**.
2.  Review the **"Credits"** section.
3.  Check your **current outstanding balance**.

*Note*: Credits are always applied to any existing balance before being available for new usage.

# Discounts

Information about bulk usage discounts and special pricing options.

## Bulk usage

**Q: Are there discounts for bulk usage?**

Yes, we offer discounts for **bulk or pre-paid purchases** exclusively for on-demand deployments—not for serverless GPUs. Please contact [inquiries@firework.ai](mailto:inquiries@fireworks.ai) if you're interested.

***

## Serverless discounts

**Q: Are there discounts for bulk spend on serverless deployments?**

Our publicly accessible services have **standard rates** for all customers. Currently, we do not offer bulk discounts for serverless deployments.

***

## Additional information

*   Discuss **annual commitment discounts**
*   Explore **enterprise-specific features and benefits**


# Billing & scaling

Understanding billing and scaling mechanisms for on-demand deployments.

## Autoscaling and costs

**Q: How does autoscaling affect my costs?**

*   **Scaling from 0**: No minimum cost when scaled to zero
*   **Scaling up**: Each new replica adds to your total cost proportionally. For example:
    *   Scaling from 1 to 2 replicas doubles your GPU costs
    *   If each replica uses multiple GPUs, costs scale accordingly (e.g., scaling from 1 to 2 replicas with 2 GPUs each means paying for 4 GPUs total)

For current pricing details, please visit our [pricing page](https://fireworks.ai/pricing).

***

## Rate-limits for on-demand deployment

**Q: What are the rate limits for on-demand deployments?**

Request throughput scales with your GPU allocation. Base allocations include:

*   Up to 8 A100 GPUs
*   Up to 8 H100 GPUs

On-demand deployments offer several advantages:

*   **Predictable pricing** based on time units, not token I/O
*   **Protected latency and performance**, independent of traffic on the serverless platform
*   **Choice of GPUs**, including A100s and H100s

Need more GPUs? Contact us to discuss higher allocations for your specific use case.

***

## On-demand billing

**Q: How does billing work for on-demand deployments?**

On-demand deployments come with automatic cost optimization features:

*   **Default autoscaling**: Automatically scales to 0 replicas when not in use
*   **Pay for what you use**: Charged only for GPU time when replicas are active
*   **Flexible configuration**: Customize autoscaling behavior to match your needs

**Best practices for cost management**:

1.  **Leverage default autoscaling**: The system automatically scales down deployments when not in use
2.  **Customize carefully**: While you can modify autoscaling behavior using our [configuration options](https://docs.fireworks.ai/guides/ondemand-deployments#customizing-autoscaling-behavior), note that preventing scale-to-zero will result in continuous GPU charges
3.  **Consider your use case**: For intermittent or low-frequency usage, serverless deployments might be more cost-effective

For detailed configuration options, see our [deployment guide](https://docs.fireworks.ai/guides/ondemand-deployments#replica-count-horizontal-scaling).

***

## Scaling structure

**Q: How does billing and scaling work for on-demand GPU deployments?**

On-demand GPU deployments have unique billing and scaling characteristics compared to serverless deployments:

**Billing**:

*   Charges start when the server begins accepting requests
*   **Billed by GPU-second** for each active instance
*   Costs accumulate even if there are no active API calls

**Scaling options**:

*   Supports **autoscaling** from 0 to multiple GPUs
*   Each additional GPU **adds to the billing rate**
*   Can handle unlimited requests within the GPU’s capacity

**Management requirements**:

*   Not fully serverless; requires some manual management
*   **Manually delete deployments** when no longer needed
*   Or configure autoscaling to **scale down to 0** during inactive periods

**Cost control tips**:

*   Regularly **monitor active deployments**
*   **Delete unused deployments** to avoid unnecessary costs
*   Consider **serverless options** for intermittent usage
*   Use **autoscaling to 0** to optimize costs during low-demand times

# Deployment issues

Troubleshooting and resolving common issues with on-demand deployments.

## Custom model issues

**Q: What are the common issues when deploying custom models?**

Here are key areas to troubleshoot for custom model deployments:

### 1. Deployment hanging or crashing

**Common causes**:

*   **Missing model files**, especially when using Hugging Face models
*   **Symlinked files** not uploaded correctly
*   **Outdated firectl version**

**Solutions**:

*   Download models without symlinks using:
    ```bash
    huggingface-cli download model_name --local-dir=/path --local-dir-use-symlinks=False
    ```
*   Update **firectl** to the latest version

### 2. LoRA adapters vs full models

*   **Compatibility**: LoRA adapters work with specific base models.
*   **Performance**: May experience slightly lower speed with LoRA, but **quality should remain similar** to the original model.
*   **Troubleshooting quality drops**:
    *   Check **model configuration**
    *   Review **conversation template**
    *   Add `echo: true` to debug requests

### 3. Performance optimization factors

Consider adjusting the following for improved performance:

*   **Accelerator count** and **accelerator type**
*   **Long prompt** settings to handle complex inputs

***

## Autoscaling

**Q: What should I expect for deployment and scaling performance?**

*   **Initial deployment**: Should complete within minutes
*   **Scaling from zero**: You may experience brief availability delays while the system scales up
*   **Troubleshooting**: If deployment takes over 1 hour, this typically indicates a crash and should be investigated
*   **Best practice**: Monitor deployment status and contact support if deployment times are unusually long

***

## Performance questions

**Q: I have more specific performance questions about improvements**

For detailed discussions on performance and optimization options:

*   **Schedule a consultation** directly with our PM, Ray Thai ([calendly](https://calendly.com/raythai))
*   Discuss your **specific use cases**
*   Get **personalized recommendations**
*   Review **advanced configuration options**

*Note*: Monitor costs carefully during the deployment and testing phase, as repeated deployments and tests can quickly consume credits.

# Hardware options

Understanding hardware choices for Fireworks.ai on-demand deployments.

## Hardware selection

**Q: Which accelerator/GPU should I use?**

It depends on your specific needs. Fireworks has two grouping of accelerators: smaller (A100) and larger (H100 and MI300X) accelerators. Small accelerators are less expensive (see [pricing page](https://fireworks.ai/pricing)), so they’re more cost-effective for low-volume use cases. However, if you have enough volume to fully utilize a larger accelerator, we find that they tend to be both faster and more cost-effective per token.

Choosing between larger accelerators depends on the use case.

*   The MI300X has the highest memory capacity and sometimes enables large models to be deployed with comparatively few GPUs. For example, unquantized Llama 3.1 70B fits on one MI300X and FP8 Llama 405B fits on 4 MI300X’s. Higher memory also may enable better throughput for longer prompts and less sharded deployments. It’s also more affordably priced than the H100.
*   The H100 offers blazing fast inference and often provides the highest throughput, especially for high-volume use cases

### Best Practices for Selection

1.  **Analyze your workload requirements** to determine which GPU fits your processing needs.
2.  Consider your **throughput needs** and the scale of your deployment.
3.  Calculate the **cost-performance ratio** for each hardware option.
4.  Factor in **future scaling needs** to ensure the selected GPU can support growth.

# Performance issues

Troubleshooting timeout errors and performance issues with serverless LLM models.

## Timeout and response times

**Q: Why am I experiencing request timeout errors and slow response times with serverless LLM models?**

Timeout errors and increased response times can occur due to **server load during high-traffic periods**.

With serverless, users are essentially **sharing a pool of GPUs** with models pre-provisioned.
The goal of serverless is to allow users and teams to **seamlessly power their generative applications** with the **latest generative models** in **less than 5 lines of code**.
Deployment barriers should be **minimal** and **pricing is based on usage**.

However there are trade-offs with this approach, namely that in order to ensure users have **consistent access** to the most in-demand models, users are also subject to **minor latency and performance variability** during **high-volume periods**.
With **on-demand deployments**, users are reserving GPUs (which are **billed by rented time** instead of usage volume) and don't have to worry about traffic spikes.

Which is why our two recommended ways to address timeout and response time issues is:

### Current solution (recommended for production)

*   **Use on-demand deployments** for more stable performance
*   **Guaranteed response times**
*   **Dedicated resources** to ensure availability

We are always investing in ways to improve speed and performance.

### Upcoming improvements

*   Enhanced SLAs for uptime
*   More consistent generation speeds during peak load times

If you experience persistent issues, please include the following details in your support request:

1.  Exact **model name**
2.  **Timestamp** of errors (in UTC)
3.  **Frequency** of timeouts
4.  **Average wait times**

### Performance optimization tips

*   Consider **batch processing** for handling bulk requests
*   Implement **retry logic with exponential backoff**
*   Monitor **usage patterns** to identify peak traffic times
*   Set **appropriate timeout settings** based on model complexity

*Note*: If you have multiple accounts, ensure that access permissions are checked across all of them.

***

## Troubleshooting firectl deployment

**Q: Why am I getting "invalid id" errors when using firectl commands like create deployment or list deployments?**

This error typically occurs when your **account ID** is not properly configured.

### Common symptoms

*   Error message: `invalid id: id must be at least 1 character long`
*   Affects multiple commands, including:
    *   `firectl create deployment`
    *   `firectl list deployments`

To resolve:

### Steps to resolve

1.  Run `firectl whoami` to check which **account id** is being used.
2.  Ensure the correct **account ID** is being used. If not, run `firectl signin` to sign-in to the right account.

***

## LoRA deployment issues

**Q: Why can’t I deploy my fine-tuned Llama 3.1 LoRA adapter?**

If you encounter the following error:

```bash
Invalid LoRA weight model.layers.0.self_attn.q_proj.lora_A.weight shape: torch.Size([16, 4096]), expected (16, 8192)
```

This issue is due to the `fireworks.json` file being set to **Llama 3.1 70b instruct** by default.

**Workaround**:

1.  Download the **model weights**.
2.  Modify the base model to be `accounts/fireworks/models/llama-v3p1-8b-instruct`.
3.  Follow the instructions in the [documentation](https://fireworks.ai/fine-tuning/model-upload) to upload and deploy the model.

# FLUX capabilities

Understanding FLUX image generation features and limitations.

## Multiple images

**Q: Can I generate multiple images in a single API call using FLUX serverless?**

No, FLUX serverless supports only one image per API call. For multiple images, send separate parallel requests—these will be automatically load-balanced across our replicas for optimal performance.

***

## Image-to-image generation

**Q: Does FLUX support image-to-image generation?**

No, image-to-image generation is not currently supported. We are evaluating this feature for future implementation. If you have specific use cases, please share them with our support team to help inform development.

***

## LoRA models

**Q: Can I create custom LoRA models with FLUX?**

Inference on FLUX-LoRA adapters is currently supported. However managed training on Fireworks with FLUX is not, although this feature is under development. Updates about our managed LoRA training service will be announced when available.

***

## Size control

**Q: How do I control output image sizes when using SDXL ControlNet?**

When using **SDXL ControlNet** (e.g., canny control), the output image size is determined by the explicit **width** and **height** parameters in your API request:

The input control signal image will be automatically:

*   **Resized** to fit your specified dimensions
*   **Cropped** to preserve aspect ratio

**Example**: To generate a 768x1344 image, explicitly include these parameters in your request:

```json
{
    "width": 768,
    "height": 1344
}
```

*Note*: While these parameters may not appear in the web interface examples, they are supported API parameters that can be included in your requests.

# Limitations & controls

Understanding model limitations, safety features, and token limits.

## Safety Features

**Q: Can safety filters or content restrictions be disabled on text generation models?**

No, safety features and content restrictions for text generation models (such as Llama, Mistral, etc.) are embedded by the original model creators during training:

*   **Safety measures** are integrated directly into the models by the teams that trained and released them.
*   These are **core behaviors** of the model, not external filters.
*   Different models may have varying levels of built-in safety.
*   **Fireworks.ai does not add additional censorship layers** beyond what is inherent in the models.
*   Original model behaviors **cannot be modified** via API parameters or configuration.

*Note*: For specific content handling needs, review the documentation of each model to understand its inherent safety features.

## Token Limits

**Q: What are the maximum completion token limits for models, and can they be increased?**

Token limits are model-specific and have technical constraints:

**Current Limitations**:

*   Many models, such as **Llama 3.1 405B**, have a **4096 token completion limit**.
*   Setting a higher `max_tokens` in API calls **will not override** this limit.
*   You will see `"finish_reason": "length"` in responses when hitting this limit.

**Why Limits Exist**:

*   **Resource management** for shared infrastructure
*   Prevents single requests from monopolizing resources
*   Helps maintain **service availability** for all users

**Working with Token Limits**:

*   Break longer generations into **multiple requests**.
    *   *Note*: This may require repeating context or prompts.
*   Be mindful that repeated context can **increase total token usage**.

**Example API Response at Limit**:

```json
{
    "finish_reason": "length",
    "usage": {
        "completion_tokens": 4096,
        "prompt_tokens": 4206,
        "total_tokens": 8302
    }
}
```

# Inference performance

Understanding model performance, quantization, and batching capabilities.

## Model quantization

**Q: What quantization format is used for the Llama 3.1 405B model?**

The **Llama 3.1 405B model** uses the **FP8 quantization format**, which:

*   Closely matches **Meta's reference implementation**
*   Provides further details in the model description at [fireworks.ai/models/fireworks/llama-v3p1-405b-instruct](https://fireworks.ai/models/fireworks/llama-v3p1-405b-instruct)
*   Has a general quantization methodology documented in our [Quantization blog](https://fireworks.ai/blog/fireworks-quantization)

*Note*: **BF16 precision** will be available soon for on-demand deployments.

***

## API capabilities

**Q: Does the API support batching and load balancing?**

Current capabilities include:

*   **Load balancing**: Yes, supported out of the box
*   **Continuous batching**: Yes, supported
*   **Batch inference**: Not currently supported (on the roadmap)
    *   Note: For batch use cases, we recommend sending multiple parallel HTTP requests to the deployment while maintaining some fixed level of concurrency.
*   **Streaming**: Yes, supported

***

## Request handling

**Q: What factors affect the number of simultaneous requests that can be handled?**

Request handling capacity depends on several factors:

*   **Model size and type**
*   **Number of GPUs allocated** to the deployment
*   **GPU type** (e.g., A100, H100)
*   **Prompt size**
*   **Generation token length**
*   **Deployment type** (serverless vs. on-demand)

# Fine-tuning models



<Note>
  Llama 3.2 1B Instruct, Llama 3.2 3B Instruct, Llama 3.1 8B Instruct and Llama
  3.1 70B Instruct are now supported!
</Note>

We utilize [LoRA (Low-Rank Adaptation)](https://huggingface.co/docs/diffusers/training/lora)
for efficient and effective fine-tuning of large language models. LoRA is used for
fine-tuning all models besides our 70B models, which uses qLoRA (quantized) to improve
training speeds. Take advantage of this opportunity to enhance your models with our
cutting-edge technology!

## Introduction

Fine-tuning a model with a dataset can be useful for several reasons:

1.  **Enhanced Precision**: It allows the model to adapt to the unique attributes and trends within the dataset, leading to significantly improved precision and effectiveness.
2.  **Domain Adaptation**: While many models are developed with general data, fine-tuning them with specialized, domain-specific datasets ensures they are finely attuned to the specific requirements of that field.
3.  **Bias Reduction**: General models may carry inherent biases. Fine-tuning with a well-curated, diverse dataset aids in reducing these biases, fostering fairer and more balanced outcomes.
4.  **Contemporary Relevance**: Information evolves rapidly, and fine-tuning with the latest data keeps the model current and relevant.
5.  **Customization for Specific Applications**: This process allows for the tailoring of the model to meet unique objectives and needs, an aspect not achievable with standard models.

In essence, fine-tuning a model with a specific dataset is a pivotal step in ensuring its enhanced accuracy, relevance, and suitability for specific applications. Let's hop on a journey of fine-tuning a model!

<Info>Fine-tuned model inference on Serverless is slower than base model inference on Serverless. For use cases that need low latency, we recommend using [on-demand deployments](https://docs.fireworks.ai/guides/ondemand-deployments). For on-demand deployements, fine-tuned model inference speeds are significant closer to base model speeds (but still slightly slower). If you are only using 1 LoRA on-demand, [merging fine-tuned weights](https://huggingface.co/docs/peft/main/en/developer_guides/lora#merge-lora-weights-into-the-base-model) into the base model when using on-demand deployments will provide identical speed to base model inference. If you have an enterprise use case that needs fast fine-tuned models, please [contact us!](https://fireworks.ai/company/contact-us)</Info>

## Installing firectl

[`firectl`](/tools-sdks/firectl/firectl) is the command-line (CLI) utiliy to manage, and deploy various resources on the [Fireworks AI Platform](https://fireworks.ai). Use `firectl` to manage fine-tuning jobs and their resulting models.

Please visit the Firectl [Getting Started](/tools-sdks/firectl/firectl) Guide on installing and using `firectl`.

## Preparing your dataset

To fine-tune a model, we need to first upload a dataset. Once uploaded, this dataset can be used to create one or more fine-tuning jobs. A dataset consists of a single JSONL file, where each line is a separate training example.

Limits:

*   Minimum number of examples is 1.
*   Maximum number of examples is 3,000,000.

Format:

*   Each line of the file must be a valid JSON object.

For the rest of this tutorial, we will use the [databricks/databricks-dolly-15k](https://huggingface.co/datasets/databricks/databricks-dolly-15k) dataset as an example. Each record in this dataset consists of a `category`, `instruction`, an optional `context`, and the expected `response`. Here are a few sample records:

```json
{"instruction": "When did Virgin Australia start operating?", "context": "Virgin Australia, the trading name of Virgin Australia Airlines Pty Ltd, is an Australian-based airline. It is the largest airline by fleet size to use the Virgin brand. It commenced services on 31 August 2000 as Virgin Blue, with two aircraft on a single route.

## Starting your tuning job

Fireworks supports three types of fine-tuning depending on the modeling objective:

*   **Text completion** - used to train a text generation model
*   **Text classification** - used to train a text classification model
*   **Conversation** - used to train a chat/conversation model

There are two ways to specify settings for your tuning job. You can create a settings YAML file and/or specify them using command-line flags. If a setting is present in both, the command-line flag takes precedence.

To start a job, run:

```shell
firectl create fine-tuning-job --settings-file path/to/settings.yaml --display-name "My Job"
```

firectl will return the fine-tuning job ID.

### Starting from a base model or a PEFT addon model

When creating a fine-tuning job, you can start tuning from a base model, or from a model you tuned earlier (PEFT addon):

1.  **Base model**: Use the `base_model` parameter to start from a pre-trained base model.
2.  **PEFT addon model**: Use the `warm_start_from` parameter to start from an existing PEFT addon model.

You must specify either `base_model` or `warm_start_from` in your settings file or command-line flags.

The following sections provide examples of a settings file for the given tasks.

### Text completion

To train a text completion model, you need to define an input template and output template from your JSON fields. To directly use a field as inputs or outputs, simply set the input and output templates as the field names.

You can also add additional text to the input and output templates. For example, this example demonstrates training on `context`, `instruction` and the `response` fields with added text around the fields. We won't use the `category` field at all.

<CodeGroup>
  ```yaml YAML(Base Model)
  # The ID of the dataset you created above.
  dataset: my-dataset

  text_completion:
    # How the fields of the JSON dataset should be formatted into the input text.
    input_template: "### GIVEN THE CONTEXT: {context}  ### INSTRUCTION: {instruction}  ### RESPONSE IS: "

    # How the fields of the JSON dataset should be formatted into the output text.
    output_template: "ANSWER: {response}"

  # The Fireworks model name of the base model.
  base_model: accounts/fireworks/models/llama-v3p1-8b-instruct
  ```

  ```yaml YAML(Warm Start)
  # The ID of the dataset you created above.
  dataset: my-dataset

  text_completion:
    # How the fields of the JSON dataset should be formatted into the input text.
    input_template: "### GIVEN THE CONTEXT: {context}  ### INSTRUCTION: {instruction}  ### RESPONSE IS: "

    # How the fields of the JSON dataset should be formatted into the output text.
    output_template: "ANSWER: {response}"

  # The Fireworks model name of the peft addon model.
  warm_start_from: accounts/<account-id>/models/<addon-model-id>
  ```
</CodeGroup>

### Conversation

To train a conversation model, the dataset must conform to the schema expected by the [Chat Completions API](querying-text-models#chat-completions-api). Each JSON object of the dataset must contain a single array field called `messages`. Each message is an object containing two fields:

*   `role` - one of "system", "user", or "assistant".
*   `content` - the content of the message.

A message with the "system" role is optional, but if specified, must be the first message of the conversation. Subsequent messages start with "user" and alternate between "user" and "assistant". For example:

```json
{"messages": [{"role": "system", "content": "You are a helpful assistant."}, {"role": "user", "content": "What color is the sky?"}, {"role": "assistant", "content": "blue"}]}
{"messages": [{"role": "user", "content": "What is 1+1?"}, {"role": "assistant", "content": "2"}, {"role": "user", "content": "Now what is 2+2?"}, {"role": "assistant", "content": "4"}]}
```

The settings file for tuning a conversation model looks like:

<CodeGroup>
  ```yaml YAML(Base Model)
  # The ID of the dataset you created above.
  dataset: my-dataset

  conversation: {}

  # The Fireworks model name of the base model.
  base_model: accounts/fireworks/models/llama-v3p1-8b-instruct
  ```

  ```yaml YAML(Warm Start)
  # The ID of the dataset you created above.
  dataset: my-dataset

  conversation: {}

  # The Fireworks model name of the peft addon model.
  warm_start_from: accounts/<account-id>/models/<addon-model-id>
  ```
</CodeGroup>

Or, you can optionally pass in a [Jinja](https://jinja.palletsprojects.com/en/3.1.x/) template to digest the messages, settings file look like:

<CodeGroup>
  ```yaml YAML(Base Model)
  # The ID of the dataset you created above.
  dataset: my-dataset

  conversation:
    jinja_template: <jinja template string>

  # The Fireworks model name of the base model.
  base_model: accounts/fireworks/models/llama-v3p1-8b-instruct
  ```

  ```yaml YAML(Warm Start)
  # The ID of the dataset you created above.
  dataset: my-dataset

  conversation:
    jinja_template: <jinja template string>

  # The Fireworks model name of the peft addon model.
  warm_start_from: accounts/<account-id>/models/<addon-model-id>
  ```
</CodeGroup>

an example of template string will look like:

```
  {%- set _mode = mode | default('generate', true) -%}
  {%- set stop_token = '
' -%}
  {%- set message_roles = ['USER', 'ASSISTANT'] -%}
  {%- set ns = namespace(initial_system_message_handled=false, last_assistant_index_for_eos=-1, messages=messages) -%}
  {%- for message in ns.messages -%}
      {%- if loop.last and message['role'] | upper == 'ASSISTANT' -%}
          {%- set ns.last_assistant_index_for_eos = loop.index0 -%}
      {%- endif -%}
  {%- endfor -%}
  {%- if _mode == 'generate' -%}
      {{ bos_token }}
  {%- endif -%}
  {%- for message in ns.messages -%}
      {%- if message['role'] | upper == 'SYSTEM' and not ns.initial_system_message_handled -%}
          {%- set ns.initial_system_message_handled = true -%}
          {{ '
system
\n\n' + message['content'] + stop_token }}
      {%- elif message['role'] | upper != 'SYSTEM' -%}
          {%- if (message['role'] | upper == 'USER') != ((loop.index0 - (1 if ns.initial_system_message_handled else 0)) % 2 == 0) -%}
              {{ raise_exception('Conversation roles must alternate user/assistant/user/assistant/...') }}
          {%- endif -%}
          {%- if message['role'] | upper == 'USER' -%}
              {{ '
user
\n\n' + message['content'] + stop_token }}
          {%- elif message['role'] | upper == 'ASSISTANT' -%}
              {%- if _mode == 'train' -%}
                  {{ '
assistant
\n\n' + unk_token + message['content'] + stop_token + unk_token }}
              {%- else -%}
                  {{ '
assistant
\n\n' + message['content'] + (stop_token if loop.index0 != ns.last_assistant_index_for_eos else '') }}
              {%- endif -%}
          {%- endif -%}
      {%- endif -%}
  {%- endfor -%}
  {%- if _mode == 'generate' and ns.last_assistant_index_for_eos == -1 -%}
      {{ '
assistant
' }}
  {%- endif -%}
```

Notice: To use conversation settings, default polished Jinja templates will be provided for models that are recommended for chat tuning to guarantee the quality, see the specs in the [conversation recommended](/fine-tuning/fine-tuning-models#supported-base-models) column at the model spec section. Otherwise, we will still provide a default generic template if no is template provided to overwrite, but the tuned model quality might not be optimal.

### Text classification

In this example, we'll only be training on the `instruction` and the `category` field. We won't use the `context` and `response` field at all

```yaml
# The ID of the dataset you created above.
dataset: my-dataset

text_classification:
  # The JSON field containing the input text to be classified.
  text: instruction

  # The JSON field containing the classification label.
  label: category

# The Hugging Face model name of the base model.
base_model: accounts/fireworks/models/llama-v3p1-8b-instruct
```

## Checking the job status

You can monitor the progress of the tuning job by running

```shell
firectl get fine-tuning-job <JOB_ID>
```

Once the job successfully completes, a model will be created in your account. You can see a list of models by running:

```shell
firectl list models
```

Or if you specified a model ID when creating the fine-tuning job, you can get the model directly:

```shell
firectl get model <MODEL_ID>
```

## Deploying and using a model

Before using your fine-tuned model for inference, you must deploy it. Please refer to our guides on [Deploying a model](/models/deploying#peft-addons) and [Querying text models](/guides/querying-text-models) for detailed instructions.

Some base models may not support serverless addons. To check:

1.  Run `firectl -a fireworks get <base-model-id>`
2.  Look under `Deployed Model Refs` to see if a `fireworks`-owned deployment exists, e.g. `accounts/fireworks/deployments/3c7a68b0`
3.  If so, then it is supported

If the base model doesn't support serverless addons, you will need use an [on-demand deployment](/models/deploying#deploying-to-on-demand) to deploy it.

## Additional tuning options

### Evaluation

By default, the fine-tuning job will not run any post-training evaluation. You can enable model evaluation and also configure the amount of training data used for eval. The default is 15%.

For classification tasks, we measure the number of examples that match the expected label.

For these conversation and text completion tasks, we use [perplexity](https://en.wikipedia.org/wiki/Perplexity) to measure how well the model generates responses.

Sample usage:

```yaml
# ...
evaluation: True
evaluation_split: 0.2
```

```shell
firectl create fine-tuning-job \
  --evaluation-split 0.2 \
  ...
```

### Epochs

Epochs is the number of epochs (i.e. passes over the training data) the job should train for. Non-integer values are supported. If not specified, a reasonable default number will be chosen for you.

**notice: we have the max value of 3 millions of dataset examples \* epochs**

```yaml
# ...
epochs: 2.0
```

```shell
firectl create fine-tuning-job \
  --epochs 2.0 \
  ...
```

### Learning rate

The learning rate used in training can be configured. If not specified, a reasonable default value will be chosen.

```yaml
# ...
learning_rate: 0.0001
```

```shell
firectl create fine-tuning-job \
  --learning-rate 0.0001 \
  ...
```

### Batch size

The batch size of dataset used in training can be configured with a positive integer less than 1024 and in power of 2. If not specified, a reasonable default value will be chosen.

```yaml
# ...
batch_size: 32
```

```shell
firectl create fine-tuning-job \
  --batch-size 32 \
  ...
```

### Lora Rank

LoRA rank refers to the dimensionality of trainable matrices in Low-Rank Adaptation fine-tuning, balancing model adaptability and computational efficiency in fine-tuning large language models. The LoRA rank used in training can be configured with a positive integer with a max value of 32. If not specified, a reasonable default value will be chosen.

```yaml
# ...
lora_rank: 16
```

```shell
firectl create fine-tuning-job \
  --lora-rank 16 \
  ...
```

### Training progress and monitoring

The fine-tuning service integrates with Weights & Biases to provide observability into the tuning process. To use this feature, you must have a Weights & Biases account and have provisioned an API key.

```yaml
wandb_entity: my-org
wandb_api_key: xxx
wandb_project: My Project
```

```shell
firectl create fine-tuning-job \
  --wandb-entity my-org \
  --wandb-api-key xxx \
  --wandb-project "My Project" \
  ...
```

### Model ID

By default, the fine-tuning job will generate a random unique ID for the model. This ID is used to refer to the model at inference time. You can optionally specify a custom ID, within (ID constraints)\[[https://docs.fireworks.ai/getting-started/concepts#resource-names-and-ids](https://docs.fireworks.ai/getting-started/concepts#resource-names-and-ids)].

```yaml
model_id: my-model
```

```shell
firectl create fine-tuning-job \
  --model-id my-model \
  ...
```

### Job ID

By default, the fine-tuning job will generate a random unique ID for the fine-tuning job. You can optionally choose a custom ID.

```yaml
job_id: my-fine-tuning-job
```

```shell
firectl create fine-tuning-job \
  --job-id my-fine-tuning-job \
  ...
```

## Downloading model weights

We are opening model weights download to everyone now! simply following the command below

```shell
firectl download model <model-id> <target local filepath>
```

## Appendix

### Supported base models

The following base models are supported for parameter-efficient fine-tuning (PEFT) and can be deployed as PEFT add-ons on Fireworks [serverless](/models/deploying#deploying-to-serverless) and [on-demand](/models/deploying#deploying-to-on-demand) deployments, using the default parameters below. Serverless deployment is only available for a subset of fine-tuned models - run "get (\<model id>)\[[https://docs.fireworks.ai/models/overview#introduction](https://docs.fireworks.ai/models/overview#introduction)]" or check the models (page)\[[https://fireworks.ai/models](https://fireworks.ai/models)] to see if there's an active serverless deployment.

### Hugging Face dataset to JSONL

To convert a Hugging Face dataset to the JSONL format supported by our fine-tuning service, you can use the following Python script:

```python
import json
from datasets import load_dataset

dataset = load_dataset("<DATASET_NAME>")

# Replace 'dataset_split' with the appropriate split you want to export, e.g., 'train', 'test', etc.
split_data = dataset["<SPLIT_NAME>"]

counter = 0
with open("<OUTPUT_FILE>.jsonl", "w") as f:
    for item in split_data:
        json.dump(item, f)
        counter += f.write("\n")

print(f"{counter} lines converted")
```

# Fine-tuning models via API



## Introduction

This guide walks you through the process of fine-tuning a model using the Fireworks REST API.

For an overview of fine-tuning see [https://docs.fireworks.ai/fine-tuning/fine-tuning-models](https://docs.fireworks.ai/fine-tuning/fine-tuning-models)

## Prepare the dataset

Create your dataset file in JSONL format. Each line should be a valid JSON object containing your training examples.

## Create a dataset record

*   **Endpoint:** POST /v1/accounts/\{account\_id}/datasets
*   **Request Body:**
    ```json
    {
      "datasetId": "your-dataset-id",
      "dataset": {
        "userUploaded": {}
      }
    }
    ```
*   **Curl Example:**
    ```bash
    curl -X POST "https://api.fireworks.ai/v1/accounts/{account_id}/datasets" \
      -H "Content-Type: application/json" \
      -H "Authorization: Bearer YOUR_API_KEY" \
      -d '{
        "datasetId": "your-dataset-id",
        "dataset": {
          "userUploaded": {}
        }
      }'
    ```

This will create a record with a dataset id you can use to upload the file.

## Upload your dataset file

### Option 1 - Upload your dataset file directly (recommended for files \< 150MB)

A streamlined file upload API is available for file sizes less than 150 MB.

*   **Endpoint:** POST /v1/accounts/\{account\_id}/datasets/\{dataset\_id}:upload
*   **Curl Example:**

```bash
curl -X POST "https://api.fireworks.ai/v1/accounts/{account_id}/datasets/{dataset_id}:upload" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -F "file=@/path/to/your-dataset-file.jsonl"
```

Post the file using the multipart/form-data format.

After this step you can [skip to Check the dataset state](#check-the-dataset-state)

### Option 2 - Upload your file using the signed upload URL (recommended for files > 150MB)

Alternatively, for larger files, get the signed URL for uploading your file directly to cloud storage.

*   **Endpoint:** POST /v1/accounts/\{account\_id}/datasets/\{dataset\_id}:getUploadEndpoint

*   **Request Body:**
    ```json
    {
      "filenameToSize": {
        "your-dataset-file.jsonl": file_size_in_bytes
      }
    }
    ```

*   **Curl Example:**

    You can use jq to directly extract the signed URL:

    ```bash
    SIGNED_UPLOAD_URL=$(
      curl -s -X POST "https://api.fireworks.ai/v1/accounts/{account_id}/datasets/{dataset_id}:getUploadEndpoint" \
        -H "Content-Type: application/json" \
        -H "Authorization: Bearer YOUR_API_KEY" \
        -d '{
          "filenameToSize": {
            "your-dataset-file.jsonl": file_size_in_bytes
          }
        }' | jq -r '.filenameToSignedUrls | to_entries | .[0].value'
    )
    ```

The response will contain a signed URL that looks similar to this:

```
https://storage.googleapis.com/fireworks-models-...
```

### Upload your dataset ( Option 2 continued )

Use the following curl command to upload your file:

```bash
curl -X PUT \
  -H "Content-Type: application/octet-stream" \
  -H "x-goog-content-length-range: FILE_SIZE_IN_BYTES,FILE_SIZE_IN_BYTES" \
  --data-binary "@/path/to/your-dataset-file.jsonl" \
  "$SIGNED_UPLOAD_URL"
```

### Validate the dataset upload ( Option 2 continued )

*   **Endpoint:** POST /v1/accounts/\{account\_id}/datasets/\{dataset\_id}:validateUpload
*   **Curl Example:**

```bash
  curl -X POST "https://api.fireworks.ai/v1/accounts/{account_id}/datasets/{dataset_id}:validateUpload" \
    -H "Authorization: Bearer YOUR_API_KEY"
```

Calling validate will finalize the dataset upload.

## Check the dataset state

*   **Endpoint:** GET /v1/accounts/\{account\_id}/datasets/\{dataset\_id}
*   **Curl Example:**

```bash
  curl -X GET "https://api.fireworks.ai/v1/accounts/{account_id}/datasets/{dataset_id}" \
    -H "Authorization: Bearer YOUR_API_KEY"
```

After successful creation and upload, the API will set the dataset state to READY

## Create a fine-tuning job

After uploading your dataset, create a fine-tuning job using the following command:

*   **Endpoint:** POST /v1/accounts/\{account\_id}/fineTuningJobs
*   **Request Body:**
    ```json
    {
      "model_id": "optional-model-id",
      "dataset": "accounts/{account_id}/datasets/{dataset_id}",
      "base_model": "accounts/fireworks/models/{base_model_id}",
      "text_completion": {
        "input_template": "### GIVEN THE CONTEXT: {context}  ### INSTRUCTION: {instruction}  ### RESPONSE IS: ",
        "output_template": "ANSWER: {response}"
      }
    }
    ```
*   **Curl Example:**
    ```bash
    curl -X POST "https://api.fireworks.ai/v1/accounts/{account_id}/fineTuningJobs" \
      -H "Content-Type: application/json" \
      -H "Authorization: Bearer YOUR_API_KEY" \
      -d '{
        "model_id": "optional-model-id",
        "dataset": "accounts/{account_id}/datasets/{dataset_id}",
        "base_model": "accounts/fireworks/models/{base_model_id}",
        "text_completion": {
          "input_template": "### GIVEN THE CONTEXT: {context}  ### INSTRUCTION: {instruction}  ### RESPONSE IS: ",
          "output_template": "ANSWER: {response}"
        }
      }'
    ```

Adjust the `input_template` and `output_template` fields as needed to match your dataset format.

By default, the fine-tuning job will generate a random unique ID for the model. This ID is used to refer to the model at inference time. You can optionally choose a custom `model_id`.

## Get the job status

*   **Endpoint:** GET /v1/accounts/\{account\_id}/fineTuningJobs/\{fine\_tuning\_job\_id}
*   **Curl Example:**
    ```bash
    curl -X POST "https://api.fireworks.ai/v1/accounts/{account_id}/fineTuningJobs/{fine_tuning_job_id}" \
      -H "Authorization: Bearer YOUR_API_KEY" \
    ```

The job should now have state PENDING or RUNNING.

## Deleting a job

*   **Endpoint:** DELETE /v1/accounts/\{account\_id}/fineTuningJobs/{fine_tuning_job_id}
*   **Curl Example:**
    ```bash
    curl -X DELETE "https://api.fireworks.ai/v1/accounts/{account_id}/fineTuningJobs/{fine_tuning_job_id}" \
      -H "Authorization: Bearer YOUR_API_KEY"
    ```

## Downloading model weights

After your fine-tuning job is complete, a model will be created in your account. You can download the model weights using the following steps.

If you specified a model\_id when creating the fine-tuning job, you can get the model weights directly.

You can see a list of models by running.

*   **Endpoint:** GET /v1/accounts/\{account\_id}/models/

Use the model\_id to get the signed URLs for downloading the model files.

*   **Endpoint:** GET /v1/accounts/\{account\_id}/models/\{model\_id}:getDownloadEndpoint
*   **Curl Example:**
    ```bash
    curl -X GET "https://api.fireworks.ai/v1/accounts/{account_id}/models/{model_id}:getDownloadEndpoint" \
      -H "Authorization: Bearer YOUR_API_KEY"
    ```

The response will contain a map of filenames to signed URLs for downloading each file.

For each file in the response, use the provided signed URL to download the file.

*   **Curl Example:**
    ```bash
    curl -o "/path/to/save/model_file.json" "$SIGNED_DOWNLOAD_URL"
    ```


# Concepts

This document outlines basic Fireworks AI concepts.

## Resources

### Account

Your account is the top-level resource under which other resources are located. Quotas are also
enforced at the account level.

For developer accounts, the account ID is auto-generated from the email address used to sign up.
Enterprise accounts can optionally choose a custom, unique account ID.

### User

A user is an email address associated with an account. Only users added to an account have access
to private resources within the account.

### Model

A model is a set of model weights and metadata associated with the model. A model cannot be used
for inference until it is deployed to one or more deployments, creating a "deployed model". There
are two types of models:

*   Base models
*   Parameter-efficient fine-tuned (PEFT) addons

See our [Models overview](/models/overview) page for details.

### Deployment

A deployment is a collection (one or more) model servers that host one base model and optionally
one or more PEFT addons (also known as LoRA adapters).

Fireworks provides a set of "serverless" deployments that host common base models. These deployments
may be used for [serverless inference](/models/overview#serverless-inference) as well as hosting [serverless addons](/models/overview#serverless-addons).

### Deployed model

A deployed model is an instance of a base model or PEFT addon that is loaded into a deployment.

### Dataset

A dataset is an immutable set of training examples that can be used to fine-tune a model.

### Fine-tuning job

A fine-tuning job is an offline training job that uses a dataset to train a PEFT addon model.

## Resource names and IDs

A full resource name looks like

```
accounts/my-account/models/my-model
```

The individual segments `my-account` and `my-model` are account and [model IDs](https://docs.fireworks.ai/models/overview), respectively.

Resource IDs must satisfy the following constraints:

*   between 1 and 63 characters (inclusive)
*   consist of a-z, 0-9, and hyphen (-)
*   does not begin or end with a hyphen (-)

Some APIs take the full resource name, while others may take a resource ID if the context is clear.

## Control plane and data plane

The Fireworks API can be split into a control plane and a data plane.

*   The **control plane** consists of APIs used for managing the lifecycle of resources. This
    includes your account, models, and deployments.
*   The **data plane** consists of the APIs used for inference and the backend services that power
    them.

## Interfaces

Users can interact with Fireworks through one of many interfaces:

*   The **web console** at [https://fireworks.ai](https://fireworks.ai)
*   The command-line interface `firectl`
*   [Python SDK](/tools-sdks/python-client/installation)

## Inference

Fireworks has 3 options for running generative AI models with unparalleled speed and costs.

*   **Serverless**: The easiest way to get started. Use the most popular models on pre-configured GPUs. Pay per token and avoid cold boots.
*   **[On-demand](https://fireworks.ai/blog/why-gpus-on-demand)** -The most flexible option for scaling. Use private GPUs to support your specific needs and only pay when you’re using it. GPUs running Fireworks software offer both \~250% improved throughput and 50% improved latency compared to vLLM. Excels for:
    *   **Production volume** - Per-token costs decrease with more volume and there are no set rate limits
    *   **Custom needs and reliability** - On-demand GPUs are private to you. This enables complete control to tailor deployments for speed/throughput/reliability or to run more specialized models
*   **Enterprise Reserved GPUs** - Use private GPUs with hardware and software set-up personally tailored by the Fireworks team for your use case. Enjoy SLAs, dedicated support, bring-your-own-cloud (BYOC) deployment options, and enterprise-only optimizations.

# Using function-calling



The function calling API allows a user to describe the set of tools/functions available to the model and have the model intelligently choose the right set of function calls to invoke given the context. This functionality allows users to build dynamic agents that can get access to real-time information &  produce structured outputs. The function calling API doesn't invoke any function calls. Instead, it generates the tool calls to make in [OpenAI](https://platform.openai.com/docs/guides/function-calling)-compatible format.

At a high level, function calling works by

1.  The user specifies a **query** along with the **list of available tools** for the model. The tools are specified using [JSON Schema](https://json-schema.org/learn/getting-started-step-by-step).
2.  The model intelligently detects intent and based on intent the model outputs either a normal conversation reply or a list of tools/functions to invoke for the user. Based on the specified schema, the model populates the correct set of arguments to invoke a function call.
3.  The user receives a reply from the model. If the reply contains a function call specification - the user can execute that method and return its output to the model along with further queries/conversation.

3.  [Open AI Cookbook on Function Calling](https://cookbook.openai.com/examples/how_to_call_functions_with_chat_models)
4.  [Function Calling Best Practices](#best-practices)

## Supported models

*   [Firefunction-v2](https://fireworks.ai/models/fireworks/firefunction-v2) - Latest and most performant model
*   [Firefunction-v1](https://fireworks.ai/models/fireworks/firefunction-v1) - Previous generation, Mixtral-based function calling model. Fast and excels at routing and structured output

## Example usage

**TL;DR** **This example tutorial is available as a Python notebook** \[[code](https://github.com/fw-ai/cookbook/blob/main/learn/function-calling/notebooks_firefunction_openai/fireworks_function_calling_demo.ipynb) | [Colab](https://colab.research.google.com/drive/1m7Bk1360CFI50y24KBVxRAKYuEU3pbPU?usp=sharing)].

For this example, let's consider a user looking for Nike's financial data. We will provide the model with a tool that the model is allowed to invoke & get access to the financial information of any company.

1.  To achieve our goal, we will provide the model with information about the `get_financial_data` function. We detail its purpose, arguments, etc in [JSON Schema](https://json-schema.org/). We send this information in through the `tools` argument. We sent the user query as usual through the `messages` argument.

```python Request

    }
  ]
}
```

2.  In our case, the model decides to invoke the tool `get_financial_data` with some specific set of arguments. **Note** The model itself won't invoke the tool. It just specifies the argument. When the model issues a function call - the completion reason would be set to `tool_calls`. The API caller is responsible for parsing the function name and arguments supplied by the model & invoking the appropriate tool.

```python Call External API
def get_financial_data(metric: str, financial_year: int, company: str):
    print(f"{metric=} {financial_year=} {company=}")
    if metric == "net_income" and financial_year == 2022 and company == "Nike":
        return {"net_income": 6_046_000_000}
    else:
        raise NotImplementedError()

function_call = chat_completion.choices[0].message.tool_calls[0].function
tool_response = locals()[function_call.name](**json.loads(function_call.arguments))
print(tool_response)
```

```json Response
metric='net_income' financial_year=2022 company='Nike'
{'net_income': 6046000000}
```

3.  The API caller obtains the response from the tool invocation & passes its response back to the model for generating a response.

```python Request
agent_response = chat_completion.choices[0].message

# Append the response from the agent
messages.append(
    {
        "role": agent_response.role, 
        "content": "",
        "tool_calls": [
            tool_call.model_dump()
            for tool_call in chat_completion.choices[0].message.tool_calls
        ]
    }
)

# Append the response from the tool 
messages.append(
    {
        "role": "tool",
        "content": json.dumps(tool_response)
    }
)

next_chat_completion = client.chat.completions.create(
    model="accounts/fireworks/models/firefunction-v2",
    messages=messages,
    tools=tools,
    temperature=0.1
)

print(next_chat_completion.choices[0].message.content)
```

```json Response
{
  "content": "Nike's net income for the year 2022 was $6,046,000,000.",
  "role": "assistant",
  "function_call": null,
  "tool_calls": null
}
```

This results in the following response

```
Nike's net income for the year 2022 was $6,046,000,000.
```

## Tools specification

`tools` field is an array, and each individual component contains the following two fields

*   `type`: `string` The type of the tool. Currently, only function is supported.
*   `function`: `object`
    *   `description`: `string` A description of what the function does, used by the model to choose when and how to call the function.
    *   `name`: `string` The name of the function to be called. Must be a-z, A-Z, 0-9, or contain underscores and dashes, with a maximum length of 64.
    *   `parameters`: `object` The parameters the functions accepts, described as a JSON Schema object. See the [JSON Schema reference](https://json-schema.org/understanding-json-schema/reference) for documentation about the format.

## Tool choice

The `tool_choice` parameter controls whether the model is allowed to call functions or not. Currently, we support values `auto`, `none` , `any` or a specific function name.

*   `auto` mode implies the model can pick between generating a message or calling a function. This is the **default** tool choice when the field is not specified.
*   `none` mode is akin to no tool specification being passed to the model.
*   To force a specific function call, you can set the`tool_choice = {"type": "function", "function": {"name":"get_financial_data"}}`. In this scenario, the model is forced to use this specific function.
*   To specify that any function call is a good function call, and a function call should always be made, you can use the `any` mode, or you can set the function name to be empty when you specify tool choice to be "function", like `tool_choice = {"type": "function"}`

## OpenAI compatibility

Our function calling API is fully compatible with OpenAI including in streaming scenarios. Compared to the OpenAI API - we don't support parallel and nested function calling.

## Best practices

1.  **Number of Functions** - The length of the list of functions specified to the model, directly impacts its performance. For best performance, keep the list of functions below 7. It's possible to see some degradation in the quality of the model as the tool list length exceeds 10.
2.  **Function Description** - The function specification follows [JSON Schema](https://json-schema.org/). For best performance, describe in great detail what the function does under the "description" section. An example of a good function description is "Get financial data for a company given the metric and year". A bad example would be "Get financial data for a company".
3.  **System Prompt** - In order to ensure optimal performance, we recommend **not** adding any additional system prompt. User-specified system prompts can interfere with the function detection & calling ability of the model. The auto-injected prompt for our function calling model is designed to ensure optimal performance.
4.  **Temperature** Setting temperature to 0.0 or some low value. This helps the model to only generate confident predictions and avoid hallucinating parameter values.
5.  **Function descriptions** Providing verbose descriptions for functions & its parameters. This is similar to prompt engineering: the more elaborate & accurate the function definition/documentation - the better the model is at deciphering the accurate intent of the function and its parameters.

## Function calling vs JSON mode

When to use function calling vs [JSON mode](/structured-responses/structured-response-formatting)? Use function calling if the use case involves decision-making or interactivity - which function to call, what parameters to fill, or how to follow up with the user to fill in missing function arguments in a chat form. JSON/Grammar mode is a preferred choice for non-interactive structured data extraction and allows you to explore non-JSON formats too.

## Example apps

## Data policy

Data from Firefunction is logged and automatically deleted after 30 days to ensure product quality and to prevent abuse ( bulk data on average # functions used, etc). This data will never be used to train models. Please contact [raythai@fireworks.ai](mailto:raythai@fireworks.ai) if you have questions, comments, or use cases where data cannot be logged.


# On-demand deployments

Deploying on your own GPUs

Fireworks allows you to create on-demand, dedicated deployments that are reserved for your own use. This has several advantages over the shared deployment Fireworks used for its serverless models:

*   Predictable performance unaffected by load caused by other users
*   No hard rate limits - but subject to the maximum load capacity of the deployment
*   Cheaper under high utilization
*   Access to larger selection of models not available via our serverless models
*   [Custom base models](/models/uploading-custom-models#custom-base-models) from Hugging Face files

<Note>If you plan on using a significant amount of on-demand deployments, consider purchasing [reserved capacity](/deployments/reservations)
for cheaper pricing and higher GPU quotas.</Note>

## Quickstart

<Steps>
  <Step title="Choose a model">
    See the "All models" list on our [Models](https://fireworks.ai/models) page for a list of pre-uploaded models on the
    Fireworks AI platform. You can also use a [custom base model](#custom-base-models).
  </Step>

  <Step title="Create a deployment">
    To create a new deployment of a [model provided by Fireworks](https://fireworks.ai/models), run:

    ```bash
    firectl create deployment accounts/fireworks/models/<MODEL_ID> --wait
    ```

    This command will complete when the deployment is `READY`. To let it run asynchronously, remove the `--wait` flag.

    <Note>The string `accounts/fireworks/models/<MODEL_ID>` is an example of a `<MODEL_NAME>`. [Read more](https://docs.fireworks.ai/models/overview#introduction) about model names.</Note>

    To create a new deployment using a custom base model, follow the [Uploading custom models](/models/uploading-custom-models#custom-base-models) guide to first upload your custom base model to the Fireworks platform. Then run:

    ```bash
    firectl create deployment <MODEL_ID>
    ```

    <Note>The deployment ID is the last part of the deployment name: `accounts/<ACCOUNT_ID>/deployments/<DEPLOYMENT_ID>`.</Note>
  </Step>

  <Step title="Verify the deployment is running">
    You can verify the deployment is complete by running:

    ```bash
    firectl get deployment <DEPLOYMENT_ID>
    ```

    The state field should show `READY`.
  </Step>

  <Step title="Query the deployment">
    To query a specific deployment, use the model identifier in the format: `<MODEL_NAME>#<DEPLOYMENT_NAME>`

    In most cases, the model identifier follows this pattern:

    `accounts/<ACCOUNT_ID>/models/<MODEL_ID>` + `#` + `accounts/<ACCOUNT_ID>/deployments/<DEPLOYMENT_ID>`

    **Example:**

    The model identifier for querying Llama3.2-3B Instruct (listed as `accounts/fireworks/models/llama-v3p2-3b-instruct`) for Acme Inq.'s deployment (deployment-id being `12ab34cd56ef`) would be:

    `accounts/fireworks/models/llama-v3p2-3b-instruct#accounts/acmeInc/deployments/12ab34cd56ef`

    **Sample Request:**

    ```bash
    curl \
      --header 'Authorization: Bearer <FIREWORKS_API_KEY>' \
      --header 'Content-Type: application/json' \
      --data '{
        "model": "accounts/fireworks/models/<MODEL_ID>#accounts/<ACCOUNT_ID>/deployments/<DEPLOYMENT_ID>",
        "prompt": "Say this is a test"
      }' \
      --url https://api.fireworks.ai/inference/v1/completions
    ```
  </Step>

  <Step title="Tear down the deployment">
    By default, deployments will automatically [scale down to zero](#customizing-autoscaling-behavior) replicas if unused (i.e. no
    inference requests) for 1 hour, and automatically delete itself if unused for one week.

    To completely delete the deployment, run:

    ```bash
    firectl delete deployment <DEPLOYMENT_ID>
    ```
  </Step>
</Steps>

**Notes:**

*   Make sure you include the `#<DEPLOYMENT_NAME>` in the model identifier when querying a specific deployment.
*   If you are unsure about the model identifier format, refer to the [Model Identifiers](https://docs.fireworks.ai/models/deploying#model-identifier) section for more details and alternatives.

## Deployment options

### Replica count (horizontal scaling)

The number of replicas (horizontal scaling) is specified by passing the `--min-replica-count` and `--max-replica-count`
flags. Increasing the number of replicas will increase the maximum QPS the deployment can support. The deployment will
automatically scale based on server load.

<Note>Auto-scaling up may fail if there is a GPU stockout. Use [reserved capacity](/deployments/reservations) to
guarantee capacity for your deployments.</Note>

The default value for `--min-replica-count` is 0. Setting `--min-replica-count` to 0 enables the deployment to auto-scale to 0 if a deployment is unused (i.e. no inference requests) for a specified "scale-to-zero" time window. While the deployment is scaled to 0, you will not pay for any GPU utilization.

The default value for `--max-replica-count` is 1 if
`--min-replica-count=0`, or the value of `--min-replica-count` otherwise.

<CodeGroup>
  ```bash create
  firectl create deployment <MODEL_NAME> \
    --min-replica-count 2 \
    --max-replica-count 3
  ```

  ```bash update
  firectl update deployment <DEPLOYMENT_ID> \
    --min-replica-count 2 \
    --max-replica-count 3
  ```
</CodeGroup>

### Customizing autoscaling behavior

You can customize certain aspects of the deployment's autoscaling behavior by setting the following flags:

*   `--scale-up-window` The duration the autoscaler will wait before scaling up a deployment after observing increased
    load. Default is `30s`.
*   `--scale-down-window` The duration the autoscaler will wait before scaling down a deployment after observing
    decreased load. Default is `10m`.
*   `--scale-to-zero-window` The duration after which there are no requests that the deployment will be scaled down to
    zero replicas. This is ignored if `--min-replica-count` is greater than 0. Default is `1h`. The minimum is `5m`.

    <Note>There will be a cold-start latency (up to a few minutes) for requests made while the deployment is scaling
    from 0 to 1 replicas.</Note>

    <Note>A deployment with `--min-replica-count` set to 0 will be automatically deleted if it receives no traffic for 7
    days.</Note>

Refer to [time.ParseDuration](https://pkg.go.dev/time#ParseDuration) for valid syntax for the duration string.

### Multiple GPUs (vertical scaling)

The number of GPUs used per replica is specified by passing the `--accelerator-count` flag. Increasing the accelerator count will increase the generation speed, time-to-first-token, and maximum QPS for your deployment, however the scaling is sub-linear. The default value for most models is 1 but may be higher for larger models that require sharding.

<CodeGroup>
  ```bash create
  firectl create deployment <MODEL_NAME> --accelerator-count 2
  ```

  ```bash update
  firectl update deployment <DEPLOYMENT_ID> --accelerator-count 2
  ```
</CodeGroup>

### Choosing hardware type

By default, a deployment will use NVIDIA A100 80 GB GPUs. You can also deploy using NVIDIA H100 80 GB or AMD MI300X GPUs by passing the `--accelerator-type` flag. Valid values for `--accelerator-type` are:

*   `NVIDIA_H100_80GB`
*   `NVIDIA_A100_80GB`
*   `AMD_MI300X_192GB` - Note that MoE-based models like DeepSeek Coder and Mixtral are currently not supported on MI300X

<Note>See [Regions](/deployments/regions) for a list of accelerator availability by region. Region can be either specified or auto-selected for a deployment upon creation. After creation, the region cannot be changed. If you plan on changing the accelerator type, you may need to re-create the deployment in a new region where it is availabile.</Note>

For advice on choosing a hardware type, see this [FAQ](https://docs.fireworks.ai/faq/deployment/ondemand/hardware-options#hardware-selection)

<CodeGroup>
  ```bash create
  firectl create deployment <MODEL_NAME> --accelerator-type="NVIDIA_H100_80GB"
  ```

  ```bash update
  firectl update deployment <DEPLOYMENT_ID> --accelerator-type="NVIDIA_H100_80GB"
  ```
</CodeGroup>

### Optimizing your deployments

By default, a balanced deployment will be created using the hardware resources you specify. Higher performance can be
achieved for long-prompt length (>\~3000 tokens) workloads by passing the `--long-prompt` flag.

<Note>This option roughly doubles the amount of GPU memory required to serve the model and requires a minimum of two
GPUs to be effective. If `--accelerator-count` is not specified, then a deployment using twice the minimum number of
GPUs (to serve without `--long-prompt`) will be created.</Note>

<CodeGroup>
  ```bash create
  firectl create deployment <MODEL_NAME> --accelerator-count=2 --long-prompt
  ```

  ```bash update
  firectl update deployment <DEPLOYMENT_ID> --long-prompt
  ```
</CodeGroup>

To update a deployment to disable this option, pass `--long-prompt=false`.

Additional optimization options are available through our enterprise plan.

## Deploying PEFT addons

By default, PEFT addons are disabled for deployments. To enable addons, pass the `--enable-addons` flag:

<CodeGroup>
  ```bash create
  firectl create deployment <MODEL_NAME> --enable-addons
  ```

  ```bash update
  firectl update deployment <DEPLOYMENT_ID> --enable-addons
  ```
</CodeGroup>

See [Uploading a custom model](/models/uploading-custom-models#peft-addons) for instructions on how to upload custom
PEFT addons. To deploy a PEFT addon to a on-demand deployment, pass the `--deployment-id` flag to `firectl deploy`. For
example:

```bash
firectl deploy <MODEL_ID> --deployment-id <DEPLOYMENT_ID>
```

<Note>The base model of the deployment must match the base model of the addon.</Note>

# Pricing

On-demand deployments are billed by GPU-second. Consult our [pricing page](https://fireworks.ai/pricing) for details.


# Prompt caching



Prompt caching is a performance optimization feature that allows Fireworks to
respond faster to requests with prompts that share common prefixes. In many
situations, it can reduce time to first token (TTFT) by as much as 80%.

Prompt caching is **enabled by default** for all Fireworks models and deployments.

For dedicated deployments, prompt caching frees up resources, leading to higher
throughput on the same hardware. Dedicated deployments on the Enterprise plan allow
additional configuration options to further optimize cache performance.

## Using prompt caching

### Common use cases

Requests to LLMs often share a large portion of their prompt. For example:

*   Long system prompts with detailed instructions
*   Descriptions of available tools for function calling
*   Growing previous conversation history for chat use cases
*   Shared per-user context, like a current file for a coding assistant

Prompt caching avoids re-processing the cached prefix of the prompt and
starts output generation much sooner.

### Structuring prompts for caching

Prompt caching works only for exact prefix matches within a prompt. To
realize caching benefits, place static content like instructions and examples at
the beginning of your prompt, and put variable content, such as user-specific
information, at the end.

For function calling models, tools are considered part of the prompt.

For vision-language models, images currently aren't cached (but this might be improved in the future).

### How it works

Fireworks will automatically find the longest prefix of the request that is
present in the cache and reuse it. The remaining portion of the prompt will be
processed as usual.

The entire prompt is stored in the cache for future reuse. Cached prompts
usually stay in the cache for at least several minutes. Depending on the model,
load level, and deployment configuration, it can be up to several hours. The
oldest prompts are evicted from the cache first.

Prompt caching doesn't alter the result generated by the model. The response you
receive will be identical to what you would get if prompt caching was not used.
Each generation is sampled from the model independently on each request and is not
cached for future usage.

## Monitoring

For dedicated deployments, information about prompt caching is returned in the
response headers. The header `fireworks-prompt-tokens` contains the number of tokens
in the prompt, out of which `fireworks-cached-prompt-tokens` are cached.

Aggregated metrics are also available in the [usage dashboard](https://fireworks.ai/account/usage?type=deployments).

## Data privacy

Serverless deployments maintain separate caches for each Fireworks account to prevent data leakage and timing attacks.

Dedicated deployments by default share a single cache across all requests.
Because prompt caching doesn't change the outputs, privacy is preserved even
if the deployment powers a multi-tenant application. It does open a minor risk
of a timing attack: potentially, an adversary can learn that a particular prompt
is cached by observing the response time. To ensure full isolation, you can pass
the `x-prompt-cache-isolation-key` header or the `prompt_cache_isolation_key`
field in the body of the request. It can contain an arbitrary string that acts
as an additional cache key, i.e., no sharing will occur between requests with
different IDs.

## Limiting or turning off caching

Additionally, you can pass the `prompt_cache_max_len` field in the request body to
limit the maximum prefix of the prompt (in tokens) that is considered for
caching. It's rarely needed in real applications but can come in handy for
benchmarking the performance of dedicated deployments by passing
`"prompt_cache_max_len": 0`.

## Advanced: cache locality for Enterprise deployments

Dedicated deployments on an Enterprise plan allow you to pass an additional hint in the request to improve cache hit rates.

First, the deployment needs to be created or updated with an additional flag:

```bash
firectl create deployment ... --enable-session-affinity
```

Then the client can pass an opaque identifier representing a single user or
session in the `user` field of the body or in the `x-session-affinity` header. Fireworks
will try to route requests with the identifier to the same server, further reducing response times.

It's best to choose an identifier that groups requests with long shared prompt
prefixes. For example, it can be a chat session with the same user or an
assistant working with the same shared context.


# Querying embedding models



Fireworks hosts many embedding models, and we will walk through an example of using `nomic-ai/nomic-embed-text-v1.5` today to see how to query Fireworks with embeddings API.

# Embedding documents

Our embedding service is OpenAI compatible. Use OpenAI's embeddings [guide](https://platform.openai.com/docs/guides/embeddings)  and OpenAI's [embeddings documentation](https://platform.openai.com/docs/api-reference/embeddings) for more detailed information on our embedding model usage.

The embedding model inputs text and outputs a vector (list) of floating point numbers to use for tasks like similarity comparisons and search.

```python Python (OpenAI 1.x)
import openai

client = openai.OpenAI(
    base_url = "https://api.fireworks.ai/inference/v1",
    api_key="<FIREWORKS_API_KEY>",
)
response = client.embeddings.create(
  model="nomic-ai/nomic-embed-text-v1.5",
  input="search_document: Spiderman was a particularly entertaining movie with...",
)

print(response)
```

This code embeds the text "search\_document: Spiderman was a particularly entertaining movie with..." and returns the following

```json Response
CreateEmbeddingResponse(data=[Embedding(embedding=[0.006380197126418352, 0.011841800063848495,...], index=0, object='embedding')], model='intfloat/e5-mistral-7b-instruct', object='list', usage=Usage(prompt_tokens=12, total_tokens=12))
```

However, you might have noticed the interesting prefix with `search_document: `, what is that supposed to mean?

# Embedding queries and document

Nomic models have been fine-tuned to take prefixes. For user query, you will need to prefix it with `search_query: `, and for documents, you need to prefix with `search_document: `. What does that mean exactly?

*   Let's say I previously used the embedding model to embed many movie reviews that I stored in a vector database. All the documents should come with a prefix of `search_document: `
*   I now want to create a movie recommendation that takes in a user query and outputs recommendations based on this data. The code below demonstrates how to embed the user query and system prompt.

```python Python (OpenAI 1.x)
import openai

client = openai.OpenAI(
    base_url = "https://api.fireworks.ai/inference/v1",
    api_key="<FIREWORKS_API_KEY>",
)

query = "I love superhero movies, any recommendations?"
task_description="Given a user query for movies, retrieve the relevant movie that can fulfill the query. "
query_emb = client.embeddings.create(
  model="nomic-ai/nomic-embed-text-v1.5",
  input=f"search_query: {query}"
)
print(query_emb)
```

To view this example end-to-end and see how to use a MongoDB vector store and Fireworks-hosted generation model for RAG, see our full [guide](https://github.com/fw-ai/cookbook/blob/main/examples/rag/mongo_basic.ipynb). For more information on what kind of prefixes are possible with nomic, please check out [this guide from nomic](https://huggingface.co/nomic-ai/nomic-embed-text-v1.5#usage).

# Variable dimensions

The model also supports variable embedding dimension sizes. In this case, we can provide dimension as a query to the embeddings.create request

```python Python (OpenAI 1.x)
import openai
client = openai.OpenAI(
  base_url="https://api.fireworks.ai/inference/v1",
  api_key="<FIREWORKS_API_KEY>",
)

response = client.embeddings.create(
  model="nomic-ai/nomic-embed-text-v1.5",
  input="search_document: I like Christmas movies, can you make any recommendations?",
  dimensions=128,
)
print(len(response.data[0].embedding))
```

You will see that the returned results are embeddings with dimension 128.

# List of available models

| Model name                                     | model size |

# Querying text models



Fireworks.ai offers an OpenAI-compatible REST API for querying text models. There are several ways to interact with it:

*   The [Fireworks Python client library](/tools-sdks/python-client/installation)
*   The [web console](https://fireworks.ai)
*   [LangChain](https://python.langchain.com/docs/integrations/providers/fireworks)
*   Directly invoking the [REST API](/api-reference/post-completions) using your favorite tools or language
*   The [OpenAI Python client](https://github.com/openai/openai-python)

## Using the web console

All Fireworks models can be accessed through the web console at [fireworks.ai](https://fireworks.ai). Clicking on a model will take you to the playground where you can enter a prompt along with additional request parameters.

Non-chat models will use the [completions API](/api-reference/post-completions) which passes your input directly into the model.

Models with a conversation config are considered chat models (also known as instruct models). By default, chat models will use the [chat completions API](/api-reference/post-chatcompletions) which will automatically format your input with the conversation style of the model. Advanced users can revert back to the completions API by unchecking the "Use chat template" option.

## Using the API

### Chat completions API

Models with a conversation config have the [chat completions API](/api-reference/post-completions) enabled. These models are typically tuned with specific conversation styles for which they perform best. For example, Llama chat models use the following [template](https://gpus.llm-utils.org/llama-2-prompt-template/):

> \
\
 \<\<SYS>>
>
> {system_prompt}
>
> \<\</SYS>>
>
> \{user\_message\_1} \


Some templates like `llama-chat` can support multiple chat messages as well. In general, we recommend users use the chat completions API whenever possible to avoid common prompt formatting errors. Even small errors like misplaced whitespace may result in poor model performance.

Here are some examples of calling the chat completions API:

<CodeGroup>
  ```python Python (Fireworks)
  from fireworks.client import Fireworks

  client = Fireworks(api_key="<FIREWORKS_API_KEY>")
  response = client.chat.completions.create(
    model="accounts/fireworks/models/llama-v3-8b-instruct",
    messages=[{
      "role": "user",
      "content": "Say this is a test",
    }],
  )
  print(response.choices[0].message.content)
  ```

  ```python Python (OpenAI 1.x)
  import openai

  client = openai.OpenAI(
      base_url = "https://api.fireworks.ai/inference/v1",

#### Overriding the system prompt

A conversation style may include a default system prompt. For example, the `llama-chat` style uses the default Llama prompt:

> You are a helpful, respectful and honest assistant. Always answer as helpfully as possible, while being safe. Your answers should not include any harmful, unethical, racist, sexist, toxic, dangerous, or illegal content. Please ensure that your responses are socially unbiased and positive in nature.

For styles that support a system prompt, you may override this prompt by setting the first message with the role `system`. For example:

```json JSON
[
  {
  	"role": "system",
  	"content": "You are a pirate."
  },
  {
  	"role": "user",
  	"content": "Hello, what is your name?"
  }
]
```

To completely omit the system prompt, you can set `content` to the empty string.

The process of generating a conversation-formatted prompt will depend on the conversation style used. To verify the exact prompt used, turn on [`echo`](#echo).

### Completions API

Text models generate text based on the provided input prompt. All text models support this basic [completions API](/api-reference/post-completions). Using this API, the model will successively generate new tokens until either the maximum number of output tokens has been reached or if the model's special end-of-sequence (EOS) token has been generated.

> NOTE: Llama-family models will automatically prepend the beginning-of-sequence (BOS) token (\
) to your prompt input. This is to be consistent with the [original implementation](https://github.com/facebookresearch/llama/blob/ef351e9cd9496c579bf9f2bb036ef11bdc5ca3d2/llama/generation.py#L264).

Here are some examples of calling the completions API:

<CodeGroup>
  ```python Python (Fireworks)
  from fireworks.client import Fireworks

  client = Fireworks(api_key="<FIREWORKS_API_KEY>")
  response = client.completion.create(
    model="accounts/fireworks/models/llama-v3-8b-instruct",
    prompt="Say this is a test",
  )

  print(response.choices[0].text)
  ```

  ```python Python (OpenAI 1.x)
  import openai

  client = openai.OpenAI(
      base_url = "https://api.fireworks.ai/inference/v1",
      api_key="<FIREWORKS_API_KEY>",
  )
  response = client.completions.create(
    model="accounts/fireworks/models/llama-v3-8b-instruct",
    prompt="Say this is a test",
  )
  print(response.choices[0].text)
  ```

  ```python Python (OpenAI 0.x)
  import openai

  openai.api_base = "https://api.fireworks.ai/inference/v1"
  openai.api_key = "<FIREWORKS_API_KEY>"

  response = openai.Completion.create(
    model="accounts/fireworks/models/llama-v3-8b-instruct",
    prompt="Say this is a test",
  )
  print(response.choices[0].text)
  ```

  ```shell cURL
  curl \
    --header 'Authorization: Bearer <FIREWORKS_API_KEY>' \
    --header 'Content-Type: application/json' \
    --data '{
      "model": "accounts/fireworks/models/llama-v3-8b-instruct",
      "prompt": "Say this is a test"
  }' \
    --url https://api.fireworks.ai/inference/v1/completions
  ```
</CodeGroup>

## Getting usage info

The returned object will contain a `usage` field containing

*   The number of prompt tokens ingested
*   The number of completion tokens (i.e. the number of tokens generated)

## Advanced options

See the API reference for the [completions](/api-reference/post-completions) and [chat completions](/api-reference/post-completions) APIs for a detailed description of these options.

### Streaming

By default, results are returned to the client once the generation is finished. Another option is to stream the results back, which is useful for chat use cases where the client can incrementally see results as each token is generated.

Here is an example with the completions API:

<CodeGroup>
  ```python Python (Fireworks)
  from fireworks.client import Fireworks

  client = Fireworks(api_key="<FIREWORKS_API_KEY>")
  response_generator = client.completion.create(
    model="accounts/fireworks/models/llama-v3p1-405b-instruct",
    prompt="Say this is a test",
    stream=True,
  )

  for chunk in response_generator:
      print(chunk.choices[0].text)
  ```

  ```python Python (OpenAI 1.x)
  import openai

  client = openai.OpenAI(
      base_url = "https://api.fireworks.ai/inference/v1",
      api_key="<FIREWORKS_API_KEY>",
  )
  response_generator = client.completions.create(
    model="accounts/fireworks/models/llama-v3p1-405b-instruct",
    prompt="Say this is a test",
    stream=True,
  )

  for chunk in response_generator:
      print(chunk.choices[0].text)
  ```

  ```python Python (OpenAI 0.x)
  import openai

  openai.api_base = "https://api.fireworks.ai/inference/v1"
  openai.api_key = "<FIREWORKS_API_KEY>"

  response_generator = openai.Completion.create(
    model="accounts/fireworks/models/llama-v3p1-405b-instruct",
    prompt="Say this is a test",
    stream=True,
  )

  for chunk in response_generator:
      print(chunk.choices[0].text, end="")
  ```

  ```shell cURL
  curl \
    --header 'Authorization: Bearer <FIREWORKS_API_KEY>' \
    --header 'Content-Type: application/json' \
    --data '{
      "model": "accounts/fireworks/models/llama-v3p1-8b-instruct",
      "prompt": "Say this is a test",
      "stream": true
  }' \
    --url https://api.fireworks.ai/inference/v1/completions
  ```
</CodeGroup>

and one with the chat completions API:

<CodeGroup>
  ```python Python (Fireworks)
  from fireworks.client import Fireworks

  client = Fireworks(api_key="<FIREWORKS_API_KEY>")
  response_generator = client.chat.completions.create(
    model="accounts/fireworks/models/llama-v3p1-8b-instruct",
    messages=[{
      "role": "user",
      "content": "Say this is a test",
    }],
    stream=True,
  )
  for chunk in response_generator:
      if chunk.choices[0].delta.content:
          print(chunk.choices[0].delta.content, end="")
  ```

  ```python Python (OpenAI 1.x)
  import openai

  client = openai.OpenAI(
      base_url = "https://api.fireworks.ai/inference/v1",
      api_key="<FIREWORKS_API_KEY>",
  )
  response_generator = client.chat.completions.create(
    model="accounts/fireworks/models/llama-v3p1-405b-instruct",
    messages=[{
      "role": "user",
      "content": "Say this is a test",
    }],
    stream=True,
  )

  for chunk in response_generator:
      if chunk.choices[0].delta.content:
          print(chunk.choices[0].delta.content, end="")

  ```

  ```python Python (OpenAI 0.x)
  import openai

  openai.api_base = "https://api.fireworks.ai/inference/v1"
  openai.api_key = "<FIREWORKS_API_KEY>"

  response_generator = openai.ChatCompletion.create(
    model="accounts/fireworks/models/llama-v3p1-405b-instruct",
    messages=[{
      "role": "user",
      "content": "Say this is a test",
    }],
    stream=True,
  )

  for chunk in response_generator:
      if "content" in chunk.choices[0].delta:
          print(chunk.choices[0].delta.content, end="")
  ```
</CodeGroup>

### Async mode

The Python client library also supports asynchronous mode for both completion and chat completion.

<CodeGroup>
  ```python Python (Fireworks)
  import asyncio
  from fireworks.client import AsyncFireworks

  client = AsyncFireworks(api_key="<FIREWORKS_API_KEY>")

  async def main():
      stream = client.completion.acreate(
          model="accounts/fireworks/models/llama-v3p1-8b-instruct",
          prompt="Say this is a test",
          stream=True,
      )
      async for chunk in stream:
          print(chunk.choices[0].text, end="")

  asyncio.run(main())
  ```

  ```python Python (OpenAI 1.x)
  import asyncio
  import openai

  client = openai.AsyncOpenAI(
      base_url = "https://api.fireworks.ai/inference/v1",
      api_key="<FIREWORKS_API_KEY>",
  )

  async def main():
      stream = await client.completions.create(
          model="accounts/fireworks/models/llama-v3-8b-instruct",
          prompt="Say this is a test",
          stream=True,
      )
      async for chunk in stream:
          print(chunk.choices[0].text, end="")

  asyncio.run(main())
  ```
</CodeGroup>

### Predicted Outputs

In cases where large parts of the LLM output are known in advance, e.g. code rewriting, specific edits within a longer document, you can improve output generation speeds with predicted outputs. Predicted outputs allows you to provide strong "guesses" of what output may look like.

To use predicted outputs, set the `prediction` field in the Fireworks API with the predicted output. For example, you may want to edit a survey and add an option to contact users by text message:

```
{
  "questions": [
    {
      "question": "Name",
      "type": "text"
    },
    {
      "question": "Age",
      "type": "number"
    },
    {
      "question": "Feedback",
      "type": "text_area"
    },
    {
      "question": "How to Contact",
      "type": "multiple_choice",
      "options": ["Email", "Phone"],
      "optional": true
    }
  ]
}
```

In this case, we expect most of the code will remain the same. We set the ‘prediction’ field to be the original survey code. The output generation speed increases using predicted outputs. See additional information about predicted outputs below the code block.

```python Python (Fireworks)
from fireworks.client import Fireworks
 
code = """{
"questions": [
    {
      "question": "Name",
      "type": "text"
    },
    {
      "question": "Age",
      "type": "number"
    },
    {
      "question": "Feedback",
      "type": "text_area"
    },
    {
      "question": "How to Contact",
      "type": "multiple_choice",
      "options": ["Email", "Phone"],
      "optional": true
    }
  ]
}
"""

client = Fireworks(api_key="<FIREWORKS_API_KEY>")

response = client.chat.completions.create(
  model="accounts/fireworks/models/llama-v3p1-70b-instruct",
  messages=[{
      "role": "user",
      "content": "Edit the How to Contact question to add an option called Text Message. Output the full edited code, with no markdown or explanations.",
    },
    {
      "role": "user",
      "content": code
    }
  ],
  temperature=0,
  prediction={"type": "content", "content": code}
)

print(response.choices[0].message.content)
```

Additional information on predicted outputs:

*   Using predicted outputs is free at this time
*   Using predicted outputs does not impact the quality of outputs generated
*   We recommend setting temperature=0 for best results for most intended use cases of predicted outputs
*   If the prediction is substantially different from the generated output, output generation speed may decrease
*   The max length of the `prediction` field is set by `max_tokens` and is 2048 by default. You need to update it if you have a longer input and prediction.
*   **Important Gotcha:** Ensure that the model output follows exactly the same format as specified in the prediction field. Common pitfalls include:
    *   Additional verbosity (e.g., "Sure, I updated this and that aspect ...")
    *   Markdown formatting (e.g., wrapping code in "\`\`\`")
    *   Extra new lines at the beginning of the output
        You may need to adjust the prompt to avoid these issues.
*   We are actively developing the feature and [welcome feedback on Discord!](https://discord.com/invite/mMqQxvFD9A)
*   Read our [blog post](https://fireworks.ai/blog/cursor) on how Cursor used predicted outputs (which leverages speculative decoding under the hood) in production with Fireworks

### Sampling options

The API auto-regressively generates text based on choosing the next token using the probability distribution over the space of tokens. For detailed information on how to implement these options, please refer to the [Chat Completions](/api-reference/post-chatcompletions) or [Completions](/api-reference/post-completions) API documentation.

#### Multiple choices

By default, the API will return a single generation choice per request. You can create multiple generations by setting the `n` parameter to the number of desired choices. The returned `choices` array will contain the result of each generation.

#### Max tokens

`max_tokens` or `max_completion_tokens` defines the maximum number of tokens the model can generate, with a default of 2000. If the combined token count (prompt + output) exceeds the model’s limit, it automatically reduces the number of generated tokens to fit within the allowed context.

#### Temperature

Temperature allows you to configure how much randomness you want in the generated text. A higher temperature leads to more "creative" results. On the other hand, setting a temperature of 0 will allow you to generate deterministic results which is useful for testing and debugging.

#### Top-p

Top-p (also called nucleus sampling) is an alternative to sampling with temperature, where the model considers the results of the tokens with top\_p probability mass. So 0.1 means only the tokens comprising the top 10% probability mass are considered.

#### Top-k

Top-k is another sampling method where the k most probable tokens are filtered and the probability mass is redistributed among tokens.

#### Min P

[`min_p`](https://arxiv.org/abs/2407.01082) specifies a probability threshold to control which tokens can be selected during generation. Tokens with probabilities lower than this threshold are excluded, making the model more focused on higher-probability tokens. The default value varies, and setting a lower value ensures more variety, while a higher value produces more predictable, focused outputs.

#### Repetition penalty

LLMs are sometimes prone to repeat a single character or a sentence. Using a frequency and presence penalty can reduce the likelihood of sampling repetitive sequences of tokens. They work by directly modifying the model's logits (un-normalized log-probabilities) with an additive contribution.

> logits\[j] -= c\[j] \* frequency\_penalty + (c\[j] > 0 ? 1 : 0) \* presence\_penalty

where

*   `logits[j]` is the logits of the j-th token
*   `c[j]` is how often that token was sampled before the current position

The [`repetition_penalty`](https://arxiv.org/pdf/1909.05858.pdf) modifies the logit (raw model output) for repeated tokens. If a token has already appeared in the prompt or output, the penalty is applied to its probability of being selected again.

**Key differences to keep in mind:**

*   `frequency_penalty`: Works on how often a word has been used, increasing the penalty for more frequent words. OAI compatible.
*   `presence_penalty`: Penalizes words once they appear, regardless of frequency. OAI compatible.
*   `repetition_penalty`: Adjusts the likelihood of repeated tokens based on previous appearances, providing an exponential scaling effect to control repetition more precisely, including from the prompt.

#### Mirostat (learning rate and target)

The [Mirostat algorithm](https://arxiv.org/abs/2007.14966) is a sampling method that helps keep the output’s unpredictability, or perplexity, at a set target. It adjusts token probabilities as the text is generated to balance between more diverse or more predictable results. This is useful when you need steady control over how random or focused the text output should be.

There are two parameters that can be adjusted:

*   `mirostat_target`: Sets the desired level of unpredictability (perplexity) for the Mirostat algorithm. A higher target results in more diverse output, while a lower target keeps the text more predictable.
*   `mirostat_lr`: Controls how quickly the Mirostat algorithm adjusts token probabilities to reach the target perplexity. A lower learning rate makes the adjustments slower and more gradual, while a higher rate speeds up the corrections.

#### Logit bias

Parameter that modifies the likelihood of specified tokens appearing. Pass in a Dict\[int, float] that maps a token\_id to a logits bias value between -200.0 and 200.0. For example

```Text python
client.completions.create(
  model="...",
  prompt="...",
  logit_bias={0: 10.0, 2: -50.0}
)
```

## Debugging options

#### Ignore EOS

This option allows you to control whether the model stops when it generated the End of Sequence (EOS) token. This is helpful primarily for performance benchmarking to reliably generate exactly `max_tokens`. Note the quality of the output may degrade as we override model's decision to generate EOS token.

### Logprobs

The `logprobs` parameter determines how many token probabilities are returned. If set to N, it will return log (base e)
probabilities for N+1 tokens: the chosen token plus the N most likely alternative tokens.

The log probabilities will be returned in a LogProbs object for each choice.

*   `tokens` contains each token of the chosen result.
*   `token_ids` contains the integer IDs of each token of the chosen result.
*   `token_logprobs` contains the logprobs of each chosen token.
*   `top_logprobs` will be a list whose length is the number of tokens of the output. Each element is a dictionary of size `logprobs`, from the most likely tokens at the given position to their respective log probabilities.

When used in conjunction with echo, this option can be set to see how the model tokenized your input.

### top\_logprobs

Setting the `top_logprobs` parameter to an integer value in conjunction with `logprobs=True` will also return the above information but in an OpenAI client-compatible format.

### Echo

Setting the `echo` option to true will cause the API to return the prompt along with the generated text. This can be used in conjunction with the chat completions API to verify the prompt template used. It can also be used in conjunction with logprobs to see how the model tokenized your input.

## Appendix

### Tokenization

Language models read and write text in chunks called tokens. In English, a **token** can be as short as one character or as long as one word (e.g., a or apple), and in some languages, tokens can be even shorter than one character or even longer than one word.

Different model families use different **tokenizers**. The <u>same text might be translated to different numbers of tokens</u> depending on the model. It means that <u>generation cost may vary per model</u> even if the model size is the same. For the Llama model family, you can use [this tool](https://belladoreai.github.io/llama-tokenizer-js/example-demo/build/) to estimate token counts. The actual number of tokens used in prompt and generation is returned in the `usage` field of the API response.


# Querying vision-language models



See [Querying text models](/guides/querying-text-models) for a general guide on the API and its options.

## Using the API

Both completions API and chat completions API are supported. However, we recommend users use the chat completions API
whenever possible to avoid common prompt formatting errors. Even small errors like misplaced whitespace may result in
poor model performance.

<Info>For Llama 3.2 Vision models, you should pass images before text in the content field, to avoid the model refusing to answer</Info>
<Info>You can pass images via a URL link or base64 encoded format. Code examples for both methods are below.</Info>

### Chat completions API

All vision-language models should have a conversation config and have [chat completions API](https://docs.fireworks.ai/api-reference/post-chatcompletions) enabled. These models are typically tuned with specific conversation styles for which they perform best. For example, Phi-3 models use the following template:

```
SYSTEM: {system message}

USER: <image>
{user message}

ASSISTANT:
```

The `<image>` substring is a special token that we insert into the prompt to allow the model to figure out where to put the image.

Here are some examples of calling the chat completions API:

<CodeGroup>
  ```python Python (Fireworks)
  import fireworks.client

  fireworks.client.api_key = "<FIREWORKS_API_KEY>"

  response = fireworks.client.ChatCompletion.create(
    model = "accounts/fireworks/models/phi-3-vision-128k-instruct",
    messages = [{

In the above example, we are providing images by providing the URL to the images. Alternatively, you can also provide the string representation of the base64 encoding of the images, prefixed with MIME types. For example:

<CodeGroup>
  ```python Python (Fireworks)
  import fireworks.client
  import base64

  # Helper function to encode the image
  def encode_image(image_path):
    with open(image_path, "rb") as image_file:
      return base64.b64encode(image_file.read()).decode('utf-8')

  # The path to your image
  image_path = "your_image.jpg"

  # The base64 string of the image
  image_base64 = encode_image(image_path)

  fireworks.client.api_key = "<FIREWORKS_API_KEY>"

  ```
</CodeGroup>

### Completions API

Advanced users can also query the completions API directly. Users will need to manually insert the image token `<image>` where appropriate and supply the list of images as an ordered list (this is true for the Phi-3 model, but may be subject to change for future vision-language models). For example:

```python
import fireworks.client

fireworks.client.api_key = "<FIREWORKS_API_KEY>"

response = fireworks.client.Completion.create(
  model = "accounts/fireworks/models/phi-3-vision-128k-instruct",
  prompt = "SYSTEM: Hello\n\nUSER:<image>\ntell me about the image\n\nASSISTANT:",
  images = ["https://images.unsplash.com/photo-1582538885592-e70a5d7ab3d3?ixlib=rb-4.0.3&ixid=M3wxMjA3fDB8MHxwaG90by1wYWdlfHx8fGVufDB8fHx8fA%3D%3D&auto=format&fit=crop&w=1770&q=80"],
)
print(response.choices[0].text)
```

## API limitations

Right now, we impose certain limits on the completions API and chat completions API as follows:

1.  The total number of images included in a single API request cannot exceed 30, regardless of whether they are provided as base64 strings or URLs.
2.  All the images should be smaller than 5MB in size, and if the time taken to download the images is longer than 1.5 seconds, the request will be dropped and you will receive an error.

## Model limitations

At the moment, we primarily offer Phi-3 vision models for serverless deployment.

## Managing images

The Chat Completions API is not stateful. That means you have to manage the messages (including images) you pass to the model yourself. However, we try to cache the image download as much as we can to save latency on model download.

For long-running conversations, we suggest passing images via URLs instead of base64 encoded images. The latency of the model can also be improved by downsizing your images ahead of time to be less than the maximum size they are expected to be.

## Calculating cost

For the Phi-3 Vision model, an image is treated as a dynamic number of tokens based on image resolution. For one image the number of tokens typically ranges from 1K to 2.5K. The pricing is otherwise identical to text models. For more information, please refer to [our pricing page here.](https://fireworks.ai/pricing)

## FAQ

### Can I fine-tune the image capabilities with VLM?

Not right now, but we will be working on Phi-3 vision model fine-tuning since it is now a more popular choice. If you are interested, please reach out to us via Discord.

### Can I use a vision-language model to generate images?

No. But we support image generation models for this purpose:

*   [Stable Diffusion](https://fireworks.ai/models/fireworks/stable-diffusion-xl-1024-v1-0)
*   [SSD-1B](https://fireworks.ai/models/fireworks/SSD-1B)
*   [Japanese Stable Diffusion](https://fireworks.ai/models/fireworks/japanese-stable-diffusion-xl)
*   [Playground v2](https://fireworks.ai/models/fireworks/playground-v2-1024px-aesthetic)

Please give these models a try and let us know how it goes!

### What type of files can I upload?

We currently support `.png`, `.jpg`, `.jpeg`, `.gif`, `.bmp`, `.tiff` and `.ppm` format images.

### Is there a limit to the size of the image I can upload?

Currently, our API is restricted to 10MB for the whole request, so the image sent through request in base64 encoding will need to be smaller than 10MB (when converted to base64 encoding). If you are using URLs, then each image needs to be smaller than 5MB.

### What is the retention policy for the images I upload?

We do not persist the images longer than the server lifetime, and will be deleted automatically.

### How do rate limits work with VLMs?

VLMs are rate-limited like all of our other LLM models, which depends on which tier of rate-limiting you are at. For more information, please check out [Pricing](https://fireworks.ai/pricing).

### Can VLMs understand image metadata?

No. If you have image metadata that you want the model to understand, please provide them through the prompt.


# Rate limits, spend limits and quotas

Rate limits, spend limits and quotas for serverless inference and on-demand deployments

## Rate limits

Rate limits exist on Serverless to ensure fair platform usage and reasonable performance for all users on serverless. The rate limit is currently `600` queries per minute (QPM). Rate limits apply across all serverless models.

<Info> We are actively working on increasing rate limits on Serverless. Come back in a few weeks to check for updates! </Info>

If you need higher rate limits, consider switching to on-demand deployments, where there are no hard rate limits and you can scale the size of your deployment to meet your needs.

## Spend limits

In order to prevent fraud, Fireworks imposes a monthly spending limit on your account. Once you hit the spending limit, your account will automatically enter a suspended state, API requests will be rejected and all Fireworks usage will be stopped. This includes serverless inference, dedicated deployments, and fine-tuning jobs.

Your spend limit will organically increase over time as you spend more on the platform. You can also increase your spend limit at any time, by purchasing prepaid credits to meet the historical spend required for a higher tier. For instance, if you are a new Tier 1 user with `$0` historical spend, you can purchase `$100` prepaid credits and become a Tier 2 user.

| **Tier**  | **Spending Limit** | **Qualification**                                                     |
| --------- | ------------------ | --------------------------------------------------------------------- |
| Tier 1    | \$50/mo            | Valid payment method added                                            |
| Tier 2    | \$500/mo           | Total historical spend of \$100+                                      |
| Tier 3    | \$5,000/mo         | Total historical spend of \$1,000+                                    |
| Tier 4    | \$50,000/mo        | Total historical spend of \$10,000+                                   |
| Unlimited | Unlimited          | Contact us at [inquiries@fireworks.ai](mailto:inquiries@fireworks.ai) |

<Note> There could be a propagation delay after you prepay for credits. You may still see "monthly usage exceeded error" for a few minutes after topup.</Note>
<Note>Credits are counted against your spending limit, so it is possible to hit the spending limit before all of your current credits are depleted.</Note>

## Other quotas

We impose limits on the number of custom models & LoRA you can have in your account, as well as the number of A100 and H100 GPUs you can deploy in your on-demand deployments. Higher quotas are available for enterprise accounts - contact the Fireworks team at [inquiries@fireworks.ai](mailto:inquiries@fireworks.ai).

| **Quota Name**                                                                         | **Default Value** | **Can be raised?** |
| -------------------------------------------------------------------------------------- | ----------------- | ------------------ |
| # [deployed models](https://docs.fireworks.ai/getting-started/concepts#deployed-model) | 100               | Yes                |
| # A100 GPUs                                                                            | 8                 | Yes                |
| # H100 GPUs                                                                            | 8                 | Yes                |

## Viewing quotas

You can view your current quota capacity by running:

```bash
firectl list quotas
```

## Account suspension

Account suspension occurs when your spending limit is hit, no payment method is on file after credits are depleted, or past invoice payment fails. If you have a failed payment, go to the \[Invoices] section at [https://fireworks.ai/billing](https://fireworks.ai/billing), pay all failed invoices, and your account will be automatically unsuspended. If your account is still suspended after 1 hour, contact the Fireworks team in Discord or via email.


# Data privacy & security

How we secure and handle your data

# Data handling

Your data is your data. No prompt or generated data is logged or stored on Fireworks; only meta-data like the number of tokens in a request is logged, as required to deliver the service. There are two exceptions:

*   For our proprietary FireFunction model, input/output data is logged for 30 days only to enable bulk analytics to improve the model, such as tracking the number of functions provided to the model.
*   For certain advanced features (e.g. FireOptimizer), users can explicitly opt-in to log data.


# Deploying models



A model must be deployed before it can be used for inference. Fireworks deploys the most popular base models to
serverless deployments that can be used out of the box (including PEFT addons). See [Querying text models](/guides/querying-text-models).

Less popular base models or custom base
models must be used with an [on-demand deployment](/guides/ondemand-deployments).

## Deploying a model

### PEFT addons

#### Deploying to serverless

Fireworks also supports deploying serverless addons for [supported base models](/fine-tuning/fine-tuning-models#appendix).
To deploy a PEFT addon to serverless, run
`firectl deploy` without passing a deployment ID:

```bash
firectl deploy <MODEL_ID>
```

Serverless addons are charged by input and output tokens for inference. There is no additional charge for deploying
serverless addons.

PEFT addons on serverless have higher latency compared with base model inference. This includes LoRA fine-tunes, which
are one type of PEFT addon. For faster inference speeds with PEFT addons, we recommend deploying to on-demand.

<Note>Unused addons may be automatically undeployed after a week.</Note>

#### Deploying to on-demand

Addons may also be deployed in an [on-demand deployment](/guides/ondemand-deployments) of [supported base models](/fine-tuning/fine-tuning-models#appendix).
To create an on-demand deployment, run:

```bash
firectl create deployment "accounts/fireworks/models/<MODEL_ID of base model>" --enable-addons
```

<Note>On-demand deployments are charged by GPU-hour. See [Pricing](https://fireworks.ai/pricing#ondemand) for
details.</Note>

Once the deployment is ready, deploy the addon to the deployment:

```bash
firectl deploy <MODEL_ID> --deployment <DEPLOYMENT_ID>
```

### Base models

Custom base models may only be used with [on-demand deployments](/guides/ondemand-deployments). To create one, run:

```bash
firectl create deployment <MODEL_ID>
```

<Note>On-demand deployments are charged by GPU-hour. See [Pricing](https://fireworks.ai/pricing#ondemand) for
details.</Note>

Use the `<MODEL_ID>` specified during [model upload](https://docs.fireworks.ai/models/uploading-custom-models#uploading-the-model-2). Creating the deployment will automatically deploy the base model to the deployment.

## Checking whether a model is deployed

You can check the status of a model deployment by looking at the "Deployed Model Refs" section from:

```
firectl get model <MODEL_ID>
```

If successful, there will be an entry with `State: DEPLOYED`.

Alternatively, you can list all deployed models within your account by running:

```
firectl list deployed-models
```

## Inference

### Model identifier

After your model is successfully deployed, it will be ready for inference. A model can be queried using one of the
following model identifiers:

*   The model and deployment names - `accounts/<ACCOUNT_ID of model>/models/<MODEL_ID>#accounts/<ACCOUNT_ID of deployment>/deployments/<DEPLOYMENT_ID>`,
    e.g.
    *   `accounts/fireworks/models/mixtral-8x7b#accounts/alice/deployments/12345678`
    *   `accounts/alice/models/custom-model#accounts/alice/deployments/12345678`

*   The model and deployment short-names - `<ACCOUNT_ID of model>/<MODEL_ID>#<ACCOUNT_ID of deployment>/<DEPLOYMENT_ID>`,
    e.g.
    *   `fireworks/mixtral-8x7b#alice/12345678`
    *   `alice/custom-model#alice/12345678`

*   Deployed model name - Instead of needing to use both the model and deployment name to refer to a deployed model, you can optionally just use a unique deployed model name. This name utilizes a unique deployed model ID that is created upon deployment. The deployed model ID takes the form \<MODEL\_ID>-\<AUTOGENERATED\_SUFFIX\&gt and can be viewed with "firectl list deployed-models"
    *   `accounts/alice/deployedModels/mixtral-8x7b-abcdef`

*   If you are deploying a custom model, you can also query it using the model name or model short-name, e.g.:
    *   `accounts/alice/models/custom-model`
    *   `alice/custom-model`

You can also use short names in place of the model and deployment names. For example:

*   `<ACCOUNT_ID>/<MODEL_ID>`
*   `<ACCOUNT_ID>/<MODEL_ID>#<ACCOUNT_ID>/<DEPLOYMENT_ID>`

### Multiple deployments

Since a model may be deployed to multiple deployments, querying by model name will route to the "default" deployed
model. You can see which deployed model entry is marked with `Default: true` by describing the model:

```
firectl get model <MODEL_ID>
...
Deployed Model Refs:
  [{
    Name: accounts/<ACCOUNT_ID>/deployedModels/<DEPLOYED_MODEL_ID_1>
    Deployment: accounts/<ACCOUNT_ID>/deployments/<DEPLOYMENT_ID_1>
    State: DEPLOYED
    Default: true
  },
  {
    Name: accounts/<ACCOUNT_ID>/deployedModels/<DEPLOYED_MODEL_ID_2>
    Deployment: accounts/<ACCOUNT_ID>/deployments/<DEPLOYMENT_ID_2>
    State: DEPLOYED
  },
]
```

To update the default deployed model, note the "Name" of the deployed model reference above. Then run:

```
firectl update deployed-model <DEPLOYED_MODEL_ID_2> --default
```

Deleting a default deployment:

To delete a default deployment you must delete all other deployments for the same model first,
or designate a different deployed model as the default as described above. This is to ensure that querying by model name
will always route to an unambiguous default deployment as long as deployments for the model exist.

### Querying the model

To test the model using the completions API, run:

```bash
curl \
  --header 'Authorization: Bearer <FIREWORKS_API_KEY>' \
  --header 'Content-Type: application/json' \
  --data '{
    "model": "<MODEL_IDENTIFIER>",
    "prompt": "Say this is a test"
}' \
  --url https://api.fireworks.ai/inference/v1/completions
```

See [Querying text models](/guides/querying-text-models) for a more comprehensive guide.

## Publishing a model

By default, models can only be queried by the account that owns them. To make a model public, pass the `--public` flag
when creating or updating it.

```bash
firectl update model <MODEL_ID> --public
```

To unpublish it, run:

```bash
firectl update model <MODEL_ID> --public=false
```


# Overview



## Introduction

A *model* is a foundational concept of the Fireworks platform, representing a set of weights and metadata that can be
deployed on hardware (i.e. a *deployment*) for inference. Each model has a [globally unique name](https://docs.fireworks.ai/getting-started/concepts#resource-names-and-ids) of the
form `accounts/<ACCOUNT_ID>/models/<MODEL_ID>`. The model IDs are:

*   Pre-populated for models that Fireworks has uploaded. For example, "llama-v3p1-70b-instruct" is the model ID for the Llama 3.1 70B model that Fireworks provides. It can be found on each model's page ([example](https://fireworks.ai/models/fireworks/llama-v3p1-70b-instruct))
*   Either auto-generated or user-specified for fine-tuned models [uploaded](https://docs.fireworks.ai/models/uploading-custom-models#uploading-the-model) or [created](https://docs.fireworks.ai/fine-tuning/fine-tuning-models#model-id) by users
*   User-specified for [custom models](https://docs.fireworks.ai/models/uploading-custom-models#uploading-the-model) uploaded by users

There are two types of models:

*   Base models
*   Parameter-efficient fine-tuned (PEFT) addons

### Base models

A base model consists of the full set of model weights. This may include models pre-trained from scratch as well as
full fine-tunes (i.e. continued pre-training). Fireworks has a library of common base models that can be used for
[serverless inference](#serverless-inference) as well as [dedicated deployments](#dedicated-deployments). Fireworks
also allows you to upload your own custom base models.

### Parameter-efficient fine-tuned (PEFT) addons

A PEFT addon is a small, fine-tuned model that significantly reduces the amount of memory required to deploy compared to
a fully fine-tuned model. A common technique for training PEFT addons is low-rank adaptation (LoRA). Fireworks
supports both [training](/fine-tuning/fine-tuning-models), [uploading](/models/uploading-custom-models#peft-addons),
and [serving](/models/deploying) PEFT addons.

PEFT addons must be deployed on a serverless or dedicated deployment for its corresponding base model.

## Using models for inference

A model must be deployed before it can be used for inference. Take a look at the [Querying text models](/guides/querying-text-models)
guide for a comprehensive overview of making LLM inference.

### Serverless inference

Fireworks supports serverless inference for popular models like Llama 3.1 405B. These models are pre-deployed by the
Fireworks team for the community to use. Take a look at the [Models](https://fireworks.ai/models) page for the latest
list of serverless models.

Serverless inference is billed on a per-token basis depending on the model size. See our [Pricing](https://fireworks.ai/pricing#text)
page for details.

<Note>Since serverless deployments are shared across users, there are no SLA guarantees for up-time or latency. It is
best-effort. The Fireworks team may also deprecate models from serverless with at least 2 weeks notice.</Note>

Custom base models are not supported for serverless inference.

### Serverless addons

The most popular base models for fine-tuning will also support serverless PEFT addons. This feature allows users to
quickly experiment and prototype with fine-tuning without having to pay extra for a dedicated deployment. See the
[Deploying to serverless](/models/deploying#deploying-to-serverless) guide for details.

<Note>Similar to serverless inference, there are no SLA guarantees for serverless addons.</Note>

### Dedicated deployments

Dedicated deployments give users the most flexibility and control over what models can be deployed and performance
guarantees. These deployments are private to you and give you access to a wide array of hardware. Both PEFT addons and
base models can be deployed to dedicated deployments.

Dedicated deployments are billed by a GPU-second basis. See our [Pricing](https://fireworks.ai/pricing#ondemand) page
for details.

Take a look at our [On-demand deployments](/guides/ondemand-deployments) guide for a comprehensive overview.

## Data privacy & security

Your data is your data. No prompt or generated data is logged or stored on Fireworks; only meta-data like the number of tokens in a request is logged, as required to deliver the service. There are two exceptions:

*   For our proprietary FireFunction model, input/output data is logged for 30 days only to enable bulk analytics to improve the model, such as tracking the number of functions provided to the model.
*   For certain advanced features (e.g. FireOptimizer), users can explicitly opt-in to log data.


# null



By default, models are served using 16-bit floating-point (FP16) precision. Quantization reduces the number of bits
required to serve the model, improving performance and reducing cost to serve. However, this can changes model numerics
which may introduce small changes to the output.

Take a look at our [blog post](https://fireworks.ai/blog/fireworks-quantization) for a detailed treatment of how
quantization affects model quality.

## Quantizing a model

A model can be quantized to 8-bit floating-point (FP8) precision using using `firectl prepare-model`:

```bash
firectl prepare-model <MODEL_ID> --precision FP8
```

<Note>This is an additive process that adds a new FP8 checkpoint for your model. The original FP16 checkpoint is still
available for use.</Note>

You can check on the status of preparation by running

```bash
firectl get model <MODEL_ID>
```

and checking if the state is still in `PREPARING`. A successfully prepared model will have the desired precision added
to the `Precisions` list.

## Creating an FP8 deployment

By default, creating a dedicated deployment will use the FP16 checkpoint. To see what precisions are available for a
model, run:

```bash
firectl get model <MODEL_ID>
```

The `Precisions` field will indicate what precisions the model has been prepared for.

To use the quantized FP8 checkpoint, pass the `--precision` flag:

```bash
firectl create deployment <MODEL> --precision FP8

In addition to the predefined set of models already available on Fireworks and models you fine-tune on the Fireworks
platform, you can also upload your own custom models. Both custom base models and PEFT addons are supported.

## PEFT addons

### Requirements

Your PEFT addon must contain the following files:

*   `adapter_config.json` - The Hugging Face adapter configuration file.
*   `adapter_model.bin` or `adapter_model.safetensors` - The saved addon file.

The `adapter_config.json` must contain the following fields:

*   `r` - The number of LoRA ranks. Must be between an integer between 4 and 64, inclusive.
*   `target_modules` - A list of target modules. Currently the following target modules are supported:
    *   `q_proj`
    *   `k_proj`
    *   `v_proj`
    *   `o_proj`
    *   `up_proj` or `w1`
    *   `down_proj` or `w2`
    *   `gate_proj` or `w3`
    *   `block_sparse_moe.gate`

Additional fields may be specified but are ignored.

### Enabling chat completions

To enable the chat completions API for your PEFT addon, add a `fireworks.json` file directory containing:

```json
{
  "conversation_config": {
    "style": "jinja",
    "args": {
      "template": "<YOUR_JINJA_TEMPLATE>"
    }
  }
}
```

### Uploading the model

To upload a PEFT addon, run the following command. The MODEL\_ID is an arbitrary [resource ID](https://docs.fireworks.ai/getting-started/concepts#resource-names-and-ids) to refer to the model within Fireworks.

> NOTE: Only some base models support PEFT addons.

```bash
firectl create model <MODEL_ID> /path/to/files/ --base-model "accounts/fireworks/models/<BASE_MODEL_ID>"
```

## Custom base models

### Requirements

Fireworks currently supports the following model architectures:

*   [Gemma](https://huggingface.co/docs/transformers/en/model_doc/gemma)
*   [Phi, Phi-3](https://huggingface.co/docs/transformers/en/model_doc/phi)
*   [Llama 1,2,3,3.1](https://huggingface.co/docs/transformers/en/model_doc/llama2)
*   [LLaVa](https://huggingface.co/docs/transformers/main/en/model_doc/llava)
*   [Mistral](https://huggingface.co/docs/transformers/en/model_doc/mistral) & [Mixtral](https://huggingface.co/docs/transformers/en/model_doc/mixtral)
*   [Qwen2](https://huggingface.co/docs/transformers/en/model_doc/qwen2)
*   [StableLM](https://huggingface.co/docs/transformers/main/en/model_doc/stablelm)
*   [Starcoder(GPTBigCode)](https://huggingface.co/docs/transformers/en/model_doc/gpt_bigcode) & [Starcoder2](https://huggingface.co/docs/transformers/main/en/model_doc/starcoder2)
*   [DeepSeek V1 & V2](https://huggingface.co/deepseek-ai)
*   [GPT NeoX](https://huggingface.co/docs/transformers/en/model_doc/gpt_neox)

The model files you will need to provide depend on the model architecture. In general, you will need the following files:

*   Model configuration: `config.json`.
    <Note>Fireworks does not support the `quantization_config` option in `config.json`.</Note>
*   Model weights, in one of the following formats:
    *   `*.safetensors`
    *   `*.bin`
*   Weights index:`*.index.json`
*   Tokenizer file(s), e.g.
    *   `tokenizer.model`
    *   `tokenizer.json`
    *   `tokenizer_config.json`

If the requisite files are not present, model deployment may fail.

### Enabling chat completions

To enable the chat completions API for your custom base model, ensure your `tokenizer_config.json` contains a
`chat_template` field. See the Hugging Face guide on [Templates for Chat Models](https://huggingface.co/docs/transformers/main/en/chat_templating)
for details.

### Uploading the model

To upload a custom base model, run the following command.

```bash
firectl create model <MODEL_ID> /path/to/files/
```

## Deploying

A model cannot be used for inference until it is deployed. See the [Deploying models](/models/deploying) guide to deploy
the model.


# Using grammar mode



## What is grammar-based structured output?

Grammar mode is the ability to specify a forced output schema for any Fireworks model via an extended BNF formal grammar ([GBNF format](https://github.com/ggerganov/llama.cpp/tree/master/grammars)). This method is popularly used to constrain model outputs in [llama.cpp](https://github.com/ggerganov/llama.cpp/blob/master/grammars/README.md). What is a formal grammar? It's a way to define rules to declare strings to be valid or invalid. See the "Syntax for Describing Grammars" below for more info. Similar to our [JSON mode](/structured-responses/structured-response-formatting) format, you provide `response_format` field in the request like `{"type": "grammar", "grammar": <your BNF grammar string> }`.

For best results, we still recommend that you do some prompt engineering and describe the desired output to the model to guide decision-making.

## Why grammar-based structured output?

*   Relying solely on system prompt engineering is finicky and time-consuming. It can be difficult to coerce the model to do certain things, for example
    *   Behave like a classifier, only output from a predefined list
    *   Output only Japanese, Chinese, a specified programming language, or otherwise prevent the model from generating a large set of of tokens
*   Sometimes JSON is not what you need (e.g. it may be finicky with string escaping) and you need some other structured output
*   Small models may have difficulty following instructions

## End-to-end examples

This guide provides a step-by-step example of creating a structured output response with grammar using the Fireworks.ai API. The example uses Python and the OpenAI library to define the schema for the output.

### Prerequisites

Before you begin, ensure you have the following:

*   Python installed on your system.
*   `openai`  libraries installed. You can install them using pip:

    ```bash
    pip install openai
    ```

Next, select the model you want to use. In this example, we use `mixtral-8x7b-instruct`, but all fireworks models support this feature. You can find your favorite model and get structured responses out of it!

### Step 1: Configure the Fireworks.ai client

You can use either Fireworks.ai or OpenAI SDK with this feature. Using OpenAI SDK with your API key and the base URL:

```python
import openai
client = openai.OpenAI(
    base_url="https://api.fireworks.ai/inference/v1",
    api_key="Your_API_Key",
)
```

Replace `"Your_API_Key"` with your actual API key.

### Step 2: Define the output grammar

Define a grammar to restrict the specified output. Let's say you have a model that is a classifier and classifies patient requests into a few predefined classes:

```
root      ::= diagnosis
diagnosis ::= "arthritis" | "dengue" | "urinary tract infection" | "impetigo" | "cervical spondylosis"
```

Then you can ask the model to only respond within these classes.

### Step 3: Specify your output grammar in your chat completions request

```python Python
from fireworks.client import Fireworks

client = Fireworks(
    api_key="Your_API_Key",
)

diagnosis_grammar = """
root      ::= diagnosis
diagnosis ::= "arthritis" | "dengue" | "urinary tract infection" | "impetigo" | "cervical spondylosis"
"""

chat_completion = client.chat.completions.create(
    model="accounts/fireworks/models/llama-v3p1-405b-instruct",
    response_format={"type": "grammar", "grammar": diagnosis_grammar},
    messages=[
        {
            "role": "system",
            "content": "Given the symptoms try to guess the possible diagnosis. Possible choices: arthritis, dengue, urinary tract infection, impetigo, cervical spondylosis. Answer with a single word",
        },
        {
            "role": "user",
            "content": "I have been having trouble with my muscles and joints. My neck is really tight and my muscles feel weak. I have swollen joints and it is hard to move around without becoming stiff. It is also really uncomfortable to walk.",
        },
    ],
)
print(chat_completion.choices[0].message.content)
```

and for the response, we will only get one of the 5 classes we specified, in this case, the model output is

```
'arthritis'
```

Note, that we still have done some prompt engineering to instruct the model about possible diagnoses in free form. Alternatively, we may have used one of the fine-tuned models for the medical domain.

## Advanced examples

### Japanese and Chinese

Make a request to the Fireworks.ai API to get a structured response. In your request, specify the output schema you used in step 3. For example, we are pretending

```python
from fireworks.client import Fireworks

client = Fireworks(
    api_key="Your_API_Key",
)

cjk_grammar = """
root        ::= jp-char+ ([ \t\n] jp-char+)*
jp-char     ::= hiragana | katakana | punctuation | cjk
hiragana    ::= [ぁ-ゟ]
katakana    ::= [ァ-ヿ]
punctuation ::= [、-〾]
cjk         ::= [一-鿿]
"""
chat_completion = client.chat.completions.create(
    model="accounts/fireworks/models/llama-v3p1-405b-instruct",
    response_format={"type": "grammar", "grammar": cjk_grammar},
    messages=[
        {
            "role": "user",
            "content": "You are a Japanese tour guide who speaks fluent Japanese. Please tell me what are some good places for me to visit in Kyoto",
        },
    ],
)




print(chat_completion.choices[0].message.content)

```

The model will reply in Japanese

```
こんにちは、私は日本語を母国語として話せるキョトの私が案内する旅行案内者です。京都を旅行にお付き合いいただきありがとうごさいます。京都にはたくさんの楽しいところがありますが、私はあなたの需要に基いて、いくつかのおすすめていきます。\n最初に、古都の一面を体感できる場所として、清水寺をおすすめします。清水寺は世界的に有名な寺院で、美しい金面山だまのホームページと、きれいな庭で知られています。\n次に、京
```

And since the grammar is actually more lenient than Japanese and covers Chinese as well, we can also just prompt the model to be a fluent Chinese speaker.

```
You are a Japanese tour guide who speaks fluent Chinese. Please tell me what are some good places for me to visit in Shanghai?",
```

And you can see here that we are trying something a little difficult, asking a Japanese tour guide to speak Chinese. But with the help from the grammar, the model replied in Chinese, with the same grammar specified

```
当您访问上海时、我建议您参观以下几个地方。\\n上海外国语大学。这是一所著名的大学、校园美景优秀、还有各种餐馆可供您选择。\\n上海中山公园。这是一座位于城市中心的公园、风景优美、有许多古老的建设和展览馆。\\n南京路。这是一条繁华的商业大街、有许多品牌商店和餐馆可供您选择。\\n上海南京东路步行街。这是全球最大的步行街之一、有许多商店和餐馆可供您选择。\\n上海世博中心。这是一座展览馆复合体、经常举办各种展览和会议
```

Without the help from the grammar, here is the model reply in a mix of Chinese and English

```
你好！uming as a Japanese tour guide who speaks fluent Chinese, I would be happy to recommend some places for you to visit in Shanghai!\\n\\n1. The Bund: This is a famous waterfront area in Shanghai that offers stunning views of the city's skyline, including the iconic Oriental Pearl Tower. You can take a leisurely stroll along the promenade and enjoy the beautiful scenery.\\n\\n2. Yuyuan Garden: This is a beautiful classical Chinese garden that dates back to the Ming Dynasty. It features pavilions, halls, rockeries, ponds, and cloisters, and is a great place to experience traditional Chinese architecture and garden design.\\n\\n3. Shanghai Tower: This is the tallest building in China and the second-tallest building in the world. You can take the elevator up to the observation deck on the 128th floor for breatht
```

### C code generation

This is one of the community contribution on llama.cpp. You can hook that with our Mixtral model and try to come up with a good solution for a coding problem you have.

```python
from fireworks.client import Fireworks
client = Fireworks(
    api_key="your_API_Key",
)

c_grammar = """
root ::= (declaration)*

declaration ::= dataType identifier "(" parameter? ")" "{" statement* "}"

dataType  ::= "int" ws | "float" ws | "char" ws
identifier ::= [a-zA-Z_] [a-zA-Z_0-9]*

parameter ::= dataType identifier

statement ::=
    ( dataType identifier ws "=" ws expression ";" ) |
    ( identifier ws "=" ws expression ";" ) |
    ( identifier ws "(" argList? ")" ";" ) |
    ( "return" ws expression ";" ) |
    ( "while" "(" condition ")" "{" statement* "}" ) |
    ( "for" "(" forInit ";" ws condition ";" ws forUpdate ")" "{" statement* "}" ) |
    ( "if" "(" condition ")" "{" statement* "}" ("else" "{" statement* "}")? ) |
    ( singleLineComment ) |
    ( multiLineComment )

forInit ::= dataType identifier ws "=" ws expression | identifier ws "=" ws expression
forUpdate ::= identifier ws "=" ws expression

condition ::= expression relationOperator expression
relationOperator ::= ("<=" | "<" | "==" | "!=" | ">=" | ">")

expression ::= term (("+" | "-") term)*
term ::= factor(("*" | "/") factor)*

factor ::= identifier | number | unaryTerm | funcCall | parenExpression
unaryTerm ::= "-" factor
funcCall ::= identifier "(" argList? ")"
parenExpression ::= "(" ws expression ws ")"

argList ::= expression ("," ws expression)*

number ::= [0-9]+

singleLineComment ::= "//" [^\n]* "\n"
multiLineComment ::= "/*" ( [^*] | ("*" [^/]) )* "*/"

ws ::= ([ \t\n]+)"""
                           
chat_completion = client.chat.completions.create(
    model="accounts/fireworks/models/llama-v3p1-405b-instruct",
    response_format={"type": "grammar", "grammar": c_grammar},
    messages=[
        {
            "role": "user",
            "content": "You are an expert in writing C code. Can you write a program that prints hello world?",
        },
    ],
)

print(chat_completion.choices[0].message.content)
```

In this case, we get a cute little valid C program as the output:

```
char\nc(int a){return 2*a;}
```

## Syntax

### Background

[Bakus-Naur Form (BNF)](https://en.wikipedia.org/wiki/Backus%E2%80%93Naur_form) is a notation for describing the syntax of formal languages like programming languages, file formats, and protocols. Fireworks API uses an extension of BNF with a few modern regex-like features, inspired by [Llama.cpp's implementation](https://github.com/ggerganov/llama.cpp/blob/master/grammars/README.md).

### Basics

In BNF, we define *production rules* that specify how a *non-terminal* (rule name) can be replaced with sequences of *terminals* (characters, specifically Unicode [code points](https://en.wikipedia.org/wiki/Code_point)) and other non-terminals. The basic format of a production rule is `nonterminal ::= sequence...`.

Consider an example of a small chess notation grammar:

```
# `root` specifies the pattern for the overall output
root ::= (
    # it must start with the characters "1. " followed by a sequence
    # of characters that match the `move` rule, followed by a space, followed
    # by another move, and then a newline
    "1. " move " " move "\n"

    # it's followed by one or more subsequent moves, numbered with one or two digits
    ([1-9] [0-9]? ". " move " " move "\n")+
)

# `move` is an abstract representation, which can be a pawn, nonpawn, or castle.
# The `[+#]?` denotes the possibility of checking or mate signs after moves
move ::= (pawn | nonpawn | castle) [+#]?

pawn ::= ...
nonpawn ::= ...
castle ::= ...
```

### Non-terminals and terminals

Non-terminal symbols (rule names) stand for a pattern of terminals and other non-terminals. They are required to be a dashed lowercase word, like `move`, `castle`, or `check-mate`.

Terminals are actual characters ([code points](https://en.wikipedia.org/wiki/Code_point)). They can be specified as a sequence like `"1"` or `"O-O"` or as ranges like `[1-9]` or `[NBKQR]`.

### Characters and character ranges

Terminals support the full range of Unicode. Unicode characters can be specified directly in the grammar, for example `hiragana ::= [ぁ-ゟ]`, or with escapes: 8-bit (`\xXX`), 16-bit (`\uXXXX`) or 32-bit (`\UXXXXXXXX`).

Character ranges can be negated with `^`:

```
single-line ::= [^\n]+ "\n"`
```

Dot `.` symbol matches any character:

```
any-three-symbol-sequence ::= ...
```

### Sequences and alternatives

The order of symbols in a sequence matter. For example, in `"1. " move " " move "\n"`, the `"1. "` must come before the first `move`, etc.

Alternatives, denoted by `|`, give different sequences that are acceptable. For example, in `move ::= pawn | nonpawn | castle`, `move` can be a `pawn` move, a `nonpawn` move, or a `castle`.

Parentheses `()` can be used to group sequences, which allows for embedding alternatives in a larger rule or applying repetition and optional symbols (below) to a sequence.

### Repetition and optional symbols

*   `*` after a symbol or sequence means that it can be repeated zero or more times.
*   `+` denotes that the symbol or sequence should appear one or more times.
*   `?` makes the preceding symbol or sequence optional.

### Comments and newlines

Comments can be specified with `#`:

```
# defines optional whitespace
ws ::= [ \t\n]+
```

Newlines are allowed between rules and between symbols or sequences nested inside parentheses. Additionally, a newline after an alternate marker `|` will continue the current rule, even outside of parentheses.

### The root rule

In a full grammar, the `root` rule always defines the starting point of the grammar. In other words, it specifies what the entire output must match.

```
# a grammar for lists
root ::= ("- " item)+
item ::= [^\n]+ "\n"
```


# Using JSON mode



## What is JSON mode?

JSON mode enables you to provide a JSON schema to force any Fireworks language model to respond in

## Why JSON responses?

1.  Clarity and Precision: Responding in JSON ensures that the output from the LLM is clear, precise, and easy to parse. This is particularly beneficial in scenarios where the response needs to be further processed or analyzed by other systems.

2.  Ease of Integration: JSON, being a widely-used format, allows for easy integration with various platforms and applications. This interoperability is essential for developers looking to incorporate AI capabilities into their existing systems without extensive modifications.

## End-to-end example

This guide provides a step-by-step example of how to create a structured output response using the Fireworks.ai API. The example uses Python and the `pydantic` library to define the schema for the output.

### Prerequisites

Before you begin, ensure you have the following:

*   Python installed on your system.
*   `openai` and `pydantic` libraries installed. You can install them using pip:

    ```bash
    pip install openai pydantic
    ```

Next, select the model you want to use. In this example, we use `mixtral-8x7b-instruct`, but all fireworks models support this feature. You can find your favorite model and get a JSON response out of it!

### Step 1: Import libraries

Start by importing the required libraries:

```python
import openai
from pydantic import BaseModel, Field
```

### Step 2: Configure the Fireworks.ai client

You can use either Fireworks.ai or OpenAI SDK with this feature. Using OpenAI SDK with your API key and the base URL:

```python
client = openai.OpenAI(
    base_url="https://api.fireworks.ai/inference/v1",
    api_key="Your_API_Key",
)
```

Replace `"Your_API_Key"` with your actual API key.

### Step 3: Define the output schema

Define a Pydantic model to specify the schema of the output. For example:

```python
class Result(BaseModel):
    winner: str
```

This model defines a simple schema with a single field `winner`. If you are not familiar with pydantic, please [check the documentation here](https://docs.pydantic.dev/latest/) . Pydantic emits JSON Schema, and you can find more informations [about it here](https://json-schema.org/).

### Step 4: Specify your output schema in your chat completions request

Make a request to the Fireworks.ai API to get a JSON response. In your request, specify the output schema you used in step 3. For example, to ask who won the US presidential election in 2012:

```python
chat_completion = client.chat.completions.create(
    model="accounts/fireworks/models/mixtral-8x7b-instruct",
    response_format={"type": "json_object", "schema": Result.model_json_schema()},
    messages=[
        {
            "role": "user",
            "content": "Who won the US presidential election in 2012? Reply just in one JSON.",
        },
    ],
)
```

### Step 5: Display the result

Finally, print the result:

```python
print(repr(chat_completion.choices[0].message.content))
```

This will display the response in the format defined by the `Result` schema. We get just one nice json response:

```
'{\n "winner": "Barack Obama"\n}'
```

And you can parse that as a plain JSON, and hook it up with the rest of your system. Current we enforce a structure with a grammar based state machine, to make sure that the LLMs would always generate all the fields in the schema. If your provided output schema is not a valid json schema, we will fail the response.

## Structured response modes

Fireworks support the following variants:

*   **Arbitrary JSON**. Similar to [OpenAI](https://platform.openai.com/docs/guides/text-generation/json-mode), you can force the model to produce any valid json by providing `{"type": "json_object"}` as `response_format` in the request. This forces the model to output JSON but does not specify what specific JSON schema to use.
*   **JSON with the given schema**. To specify a given JSON schema, you can provide the schema according to [JSON schema spec](https://json-schema.org/specification) to be imposed on the model generation. See supported constructs in the next section.

**Important:** when using JSON mode, it's also crucial to instruct the model to produce JSON and describe the desired schema via a system or user message. Without this, the model may generate an unending stream of whitespace until the generation reaches the token limit, resulting in a long-running and seemingly "stuck" request.

To get the best outcome, you need to include the schema in **both the prompt and the schema.**

Technically, it means that when using "JSON with the given schema" mode, the model doesn't automatically "see" the schema passed in the `response_format` field. Adherence to the schema is forced upon the model during sampling. So for best results, you need to include the desired schema in the prompt in addition to specifying it as `response_format`. You may need to experiment with the best way to describe the schema in the prompt depending on the model: besides JSON schema, describing it in plain English might work well too, e.g. "extract name and address of the person in JSON format".

**Note:** that the message content may be partially cut off if `finish_reason="length"`, which indicates the generation exceeded `max_tokens` or the conversation exceeded the max context length. In this case, the return value might not be a valid JSON.

Structured response modes work for both Completions and Chat Completions APIs.

If you use [function calling](/docs/function-calling), JSON mode is enabled automatically and function schema is added to the prompt. So none of the comments above apply.

### JSON schema constructs

Fireworks supports a subset of [JSON schema specification](https://json-schema.org/specification).

Supported:

*   Nested schemas composition, including `anyOf` and `$ref`
*   `type`: `string`, `number`, `integer` `boolean`, `object`, `array`, `null`
*   `properties` and `required` for objects
*   `items` for arrays

Fireworks API doesn't error out on unsupported constructs. They just won't be enforced. Not yet supported constraints include:

*   Sophisticated composition with `oneOf`
*   Length/size constraints for objects and arrays
*   Regular expressions via `pattern`

**Note**: JSON specification [allows for arbitrary field names](https://json-schema.org/understanding-json-schema/reference/object#additionalproperties) to appear in an object with the `properties` constraint unless `"additionalProperties": false` or `"unevaluatedProperties": false` is provided. It's a poor default for LLM constrained generation since any hallucination would be accepted. Thus Fireworks treats any schema with `properties` constraint as if it had `"unevaluatedProperties": false`.

An example of `response_format` field with the schema accepting an object with two fields - a required string and an optional integer:

```
{
  "type": "json_object",
  "schema": {
    "type": "object",
    "properties": {
      "foo": {"type": "string"},
      "bar": {"type": "integer"}
    },
    "required": ["foo"]
  }
}
```

## Similar features

Check out our [function calling model](/guides/function-calling) if you're interested in use cases like:

*   Multi-turn capabilities: For example, the ability for the model to ask for clarifying information about parameters
*   Routing: The ability for the model to route across multiple different options or models. Instead of just having one possible JSON Schema, you have many different JSON schemas to work across.

Check out [grammar mode](/structured-responses/structured-output-grammar-based) if you want structured output specified not through JSON, but rather through an arbitrary grammar (limit output to specific words, character limits, character types, etc).

```


# OpenAI compatibility



You can use [OpenAI Python client library](https://github.com/openai/openai-python) to interact with Fireworks.
This makes migration of existing applications already using OpenAI particularly easy.

## Specify endpoint and API key

You can override parameters for the entire application using environment variables

```shell Shell
export OPENAI_API_BASE="https://api.fireworks.ai/inference/v1"
export OPENAI_API_KEY="<YOUR_FIREWORKS_API_KEY>"
```

or by setting these values in Python

```python
import openai

# warning: it has a process-wide effect
openai.api_base = "https://api.fireworks.ai/inference/v1"
openai.api_key = "<YOUR_FIREWORKS_API_KEY>"
```

Alternatively, you may specify these parameters for a single request (useful if you mix calls to OpenAI and Fireworks in the same process):

```python
# api_base and api_key can be passed to any of the supported APIs
chat_completion = openai.ChatCompletion.create(
    api_base="https://api.fireworks.ai/inference/v1",
    api_key = "<YOUR_FIREWORKS_API_KEY",
    ...
)
```

## Usage

Use OpenAI's SDK how you'd normally would. Just ensure that the `model` parameter refers to one of [Fireworks models](https://fireworks.ai/models).

### Completion

Simple completion API that doesn't modify provided prompt in any way

```python
completion = openai.Completion.create(
  model="accounts/fireworks/models/llama-v3p1-8b-instruct",
  prompt="The quick brown fox",
)
print(completion.choices[0].text)
```

### Chat Completion

Works best for models fine-tuned for conversation (e.g. llama\*-chat variants)

```python
chat_completion = openai.ChatCompletion.create(
  model="accounts/fireworks/models/llama-v3p1-8b-instruct",
  messages=[
    {
      "role": "system",
     	"content": "You are a helpful assistant.",
    },
    {
      "role": "user",
      "content": "Say this is a test",
    },
  ],
)
print(chat_completion.choices[0].message.content)
```

## API compatibility

### Differences

The following options have minor differences:

*   `stop`: the returned string includes the stop word for Fireworks while it's omitted for OpenAI (it can be easily truncated on client side)
*   `max_tokens`: behaves differently if the model context length is exceeded. If the length of `prompt` or `messages` plus `max_tokens` is higher than the model's context window, `max_tokens` will be adjusted lower accordingly. OpenAI returns invalid request error in this situation. This behavior can be adjusted by `context_length_exceeded_behavior` parameter.

### Token usage for streaming responses

OpenAI API returns usage stats (number of tokens in prompt and completion) for non-streaming responses but doesn't for the streaming ones (see [forum post](https://community.openai.com/t/chat-completion-stream-api-token-usage/352964)).

Fireworks.ai returns usage stats in both cases. For streaming responses, the `usage` field is returned in the very last chunk on the response (i.e. the one having `finish_reason` set). For example:

```bash cURL
curl --request POST \           
     --url https://api.fireworks.ai/inference/v1/completions \
     --header "accept: application/json" \
     --header "authorization: Bearer $API_KEY" \
     --header "content-type: application/json" \
     --data '{"model": "accounts/fireworks/models/starcoder-16b-w8a16", "prompt": "def say_hello_world():", "max_tokens": 100, "stream": true}'
```

```
data: {..., "choices":[{"text":"\n  print('Hello,","index":0,"finish_reason":null,"logprobs":null}],"usage":null}
       
data: {..., "choices":[{"text":" World!')\n\n\n","index":0,"finish_reason":null,"logprobs":null}],"usage":null}
       
data: {..., "choices":[{"text":"say_hello_","index":0,"finish_reason":null,"logprobs":null}],"usage":null}
       
data: {..., "choices":[{"text":"world()\n","index":0,"finish_reason":"stop","logprobs":null}],"usage":{"prompt_tokens":7,"total_tokens":24,"completion_tokens":17}}

data: [DONE]
```

<Note>
  Note, that if you're using OpenAI SDK, they `usage` field won't be listed in the SDK's structure definition. But it can be accessed directly. For example:

  *   In Python SDK, you can access the attribute directly, e.g. `for chunk in openai.ChatCompletion.create(...): print(chunk["usage"])`.
  *   In TypeScript SDK, you need to cast away the typing, e.g. `for await (const chunk of await openai.chat.completions.create(...)) { console.log((chunk as any).usage); }`.
</Note>

### Not supported options

The following options are not yet supported:

*   `presence_penalty`
*   `frequency_penalty`
*   `best_of`: you can use `n` instead
*   `logit_bias`
*   `functions`: you can use our [LangChain integration](https://python.langchain.com/docs/integrations/providers/fireworks) to achieve similar functionality client-side

Please reach out to us on [Discord](https://discord.gg/fireworks-ai) if you have a use case requiring one of these.
