## Model overview

`codellama-13b-instruct` is a 13 billion parameter Llama model developed by Meta, tuned for coding and conversation. It is part of the Code Llama family of models, which also includes variants with 7 billion, 34 billion, and 70 billion parameters. These models are built by fine-tuning [Llama 2](https://github.com/facebookresearch/llama) and show improvements on inputs with up to 100,000 tokens. The 7 billion and 13 billion versions of Code Llama and Code Llama-Instruct also support infilling based on surrounding content.

## Model inputs and outputs

`codellama-13b-instruct` takes in a prompt and generates text output. The model supports a variety of input parameters, including top-k, top-p, temperature, max tokens, and different penalty settings to control the output. The output is a list of generated text.

### Inputs
- **Prompt**: The input text to guide the model's generation.
- **System Prompt**: An optional system-level prompt that helps guide the model's behavior.
- **Max Tokens**: The maximum number of tokens to generate in the output.
- **Temperature**: Controls the randomness of the output, with higher values generating more diverse text.
- **Top K**: Limits the number of most likely tokens to consider during generation.
- **Top P**: Limits the cumulative probability of the most likely tokens to consider during generation.
- **Frequency Penalty**: Penalizes the model for generating the same tokens frequently.
- **Presence Penalty**: Penalizes the model for generating tokens that have not appeared in the prompt.
- **Repeat Penalty**: Penalizes the model for generating repetitive text.

### Outputs
- **Generated Text**: A list of text generated by the model in response to the input prompt.

## Capabilities

`codellama-13b-instruct` is capable of generating code, providing explanations, and following instructions in a variety of domains. It can be used for tasks like code generation, code explanation, and even open-ended conversation. The model has been trained with safety mitigations to help address potential risks.

## What can I use it for?

`codellama-13b-instruct` can be used for a wide range of applications, from building AI-powered coding assistants to developing chatbots and virtual assistants. The model's capabilities make it useful for tasks like automating code generation, explaining programming concepts, and assisting with open-ended tasks. Developers and businesses can experiment, innovate, and scale their ideas using this model.
