# 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, device_map="auto") |
|
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" |
|
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)) |
|
``` |
|
|
|
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 |
|
``` |
|
|
|

|
### 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. |
