This is a reference LLM from [Data-Juicer](https://github.com/alibaba/data-juicer).

The model architecture is LLaMA-7B and we built it upon the pre-trained [checkpoint](https://huggingface.co/huggyllama/llama-7b). 
The model is fine-trained on 40k English chat samples of Data-Juicer's refined [alpaca-CoT data](https://github.com/alibaba/data-juicer/blob/main/configs/data_juicer_recipes/alpaca_cot/README.md#refined-alpaca-cot-dataset-meta-info).
It beats LLaMA-7B fine-tuned on 52k Alpaca samples in GPT-4 evaluation.
