# FreeWilly

## Model Description

`Stable Beluga 1` is a Llama65B model fine-tuned on an Orca style Dataset

## Usage

### Apply Delta Weights

Stable Beluga 1 cannot be used from the `stabilityai/StableBeluga1-Delta` 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-model-path /path/to/model_weights/llama-65b --target-model-path StableBeluga1 --delta-path stabilityai/StableBeluga1-Delta
```



Start chatting with `Stable Beluga 1` using the following code snippet:

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

tokenizer = AutoTokenizer.from_pretrained("your_path_to_StableBeluga1", use_fast=False)
model = AutoModelForCausalLM.from_pretrained("your_path_to_StableBeluga1", torch_dtype=torch.float16, low_cpu_mem_usage=True, device_map="auto")

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 Stable Beluga, 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"

inputs = tokenizer(prompt, return_tensors="pt").to("cuda")
output = model.generate(**inputs, do_sample=True, top_p=0.95, top_k=0, max_new_tokens=256)

print(tokenizer.decode(output[0], skip_special_tokens=True))
```

Stable Beluga 1 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 Stable Beluga 1
```

### 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

### Ethical Considerations and Limitations

Beluga is a new technology that carries risks with use. Testing conducted to date has been in English, and has not covered, nor could it cover all scenarios. For these reasons, as with all LLMs, Beluga's potential outputs cannot be predicted in advance, and the model may in some instances produce inaccurate, biased or other objectionable responses to user prompts. Therefore, before deploying any applications of Beluga, developers should perform safety testing and tuning tailored to their specific applications of the model.
