Model type
Wombat-7B-GPT4 is general-purpose instruction-following language model aligned with GPT4 (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-gpt4 \
    --delta GanjinZero/wombat-7b-gpt4-delta

where apply_delta.py is from code.

To infer with Wombats: Please refer to code.
