# FreeWilly

## Model Description

`FreeWilly` is a Llama65B model finetuned on an Orca style Dataset

## Usage

### Apply Delta Weights

FreeWilly1 cannot be used from the `stabilityai/FreeWilly1-Delta-SafeTensor` weights alone. To obtain the correct model, one must add back the difference between LLaMA 65B and `stabilityai/FreeWilly1-Delta-SafeTensor` weights. We provide the [`apply_delta.py`](https://huggingface.co/stabilityai/FreeWilly1-Delta-SafeTensor/raw/main/apply_delta.py) script to automate the conversion, which you can run as:


```sh
python3 apply_delta.py --base /path/to/model_weights/llama-65b --target FreeWilly1 --delta stabilityai/FreeWilly1-Delta-SafeTensor
```



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

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

tokenizer = AutoTokenizer.from_pretrained("your_path_to_freewilly", use_fast=False)
model = AutoModelForCausalLM.from_pretrained("your_path_to_freewilly", torch_dtype=torch.float16, low_cpu_mem_usage=True, use_accelerate=True)
generator = pipeline(model=model, tokenizer=tokenizer)
system_prompt = "Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.\n\n"
system_prompt += "### Instruction:\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}### Input: {message}\n\n### Response:\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 prompts formatted similarly to Alpaca as below:
```
Below is an instruction that describes a task, paired with an input that provides further context. Write a response that appropriately completes the request.

## Instruction:
This is a system prompt, please behave and help the user.

### Input:
Your prompt here

### Response
The output of FreeWilly
```

## Model Details

### Training Dataset

`FreeWilly` 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   | 512        | 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.
