## Model details

**Organization developing the model**  
Alibaba DAMO Academy, Tsinghua University

**Model date**  
Wombat-7B was released at 2023/04/13.

**Model version**  
Wombat-7B

**Training dataset**  
The training data of Wombat-7B is released in the [RRHF](https://github.com/GanjinZero/RRHF).

**Model type**  
Wombat-7B is a general-purpose instruction-following language model aligned with chatGPT (as proxy human preferences), fine-tuned from Alpaca models.  
We use a novel method named RRHF (Rank Response to align Human Feedback) to fine-tune Alpaca.

**How to use**
To recover Wombats from delta parameters:  
```bash 
python apply_delta.py \
    --base ./llama-7b \
    --target ./wombat-7b \
    --delta GanjinZero/wombat-7b-delta
```
where **apply_delta.py** is from [code](https://github.com/GanjinZero/RRHF/blob/main/apply_delta.py).

To infer with Wombats: Please refer to [code](https://github.com/GanjinZero/RRHF/blob/main/single_sentence_inference.py).

**Primary intended uses**  
The primary use of Wombat-7B and Wombat-7B-GPT4 is research on learning from human feedback and is a prototype of RRHF methods.

**Primary intended users**  
The primary intended users of Wombat-7B and Wombat-7B-GPT4 are researchers in natural language processing, machine learning and artificial intelligence.

**Out-of-scope use cases**  
Wombat-7B and Wombat-7B-GPT4 are not finetuned with proxy human feedback of OpenAI chatGPT and GPT4 and are not intended for use in production systems.
Any usage must not be competing with the OpenAI API.
