# FreeWilly

## Model Description

`FreeWilly2` is a Llama2 70B model finetuned on an Orca style Dataset

## Usage

Start chatting with `FreeWilly2` using the following code snippet:

```python
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline

tokenizer = AutoTokenizer.from_pretrained("stabilityai/FreeWilly2, use_fast=False)
model = AutoModelForCausalLM.from_pretrained("stabilityai/FreeWilly2", torch_dtype=torch.float16, low_cpu_mem_usage=True, use_accelerate=True)
generator = pipeline(model=model, tokenizer=tokenizer)
system_prompt = "### System:\nYou are Free Willy, an AI that follows instructions extremely well. Help as much as you can. Remember, be safe, and don't do anything illegal.\n\n"

message = "Write me a poem please"
prompt = f"{system_prompt}### User: {message}\n\n### Assistant:\n"

output = generator(prompt, num_return_sequences=1, do_sample=True, top_p=0.95, top_k=0)
print(output)
```

FreeWilly should be used with this prompt format:
```
### System:
This is a system prompt, please behave and help the user.

### User:
Your prompt here

### Assistant
The output of FreeWilly2
```

## Model Details

* **Developed by**: [Stability AI](https://stability.ai/)
* **Model type**: FreeWilly is an auto-regressive language model fine-tuned on Llama2 70B.
* **Language(s)**: English
* **Library**: [HuggingFace Transformers](https://github.com/huggingface/transformers)
* **License**: Fine-tuned checkpoints (`FreeWilly2`) is licensed under the Non-Commercial Creative Commons license ([CC BY-NC-4.0](https://creativecommons.org/licenses/by-nc/4.0/))
* **Contact**: For questions and comments about the model, please email `lm@stability.ai`

### Training Dataset

`FreeWilly2` is trained on our internal Orca-style dataset

### Training Procedure

Models are learned via supervised fine-tuning on the aforementioned datasets, trained in mixed-precision (BF16), and optimized with AdamW. We outline the following hyperparameters:

| Dataset           | Batch Size | Learning Rate |Learning Rate Decay| Warm-up | Weight Decay | Betas       |
|-------------------|------------|---------------|-------------------|---------|--------------|-------------|
| Orca pt1 packed   | 256        | 3e-5          | Cosine to 3e-6    | 100     | 1e-6         | (0.9, 0.95) |
| Orca pt2 unpacked | 512        | 3e-5          | Cosine to 3e-6    | 100     | 1e-6         | (0.9, 0.95) |

## Use and Limitations

### Intended Use

These models are intended for research only, in adherence with the [CC BY-NC-4.0](https://creativecommons.org/licenses/by-nc/4.0/) license.

### Limitations and bias

Although the aforementioned dataset helps to steer the base language models into "safer" distributions of text, not all biases and toxicity can be mitigated through fine-tuning. We ask that users be mindful of such potential issues that can arise in generated responses. Do not treat model outputs as substitutes for human judgment or as sources of truth. Please use it responsibly.
