Considering LLaMA's license constraints, the model is for research and learning only. Please strictly respect LLaMA's usage policy. We are not allowed to publish weights for LLaMA, of course, even finetuned, but there is no problem publishing the difference, a patch that we suggest to apply to the files. The encryption is a simple XOR between files, ensuring that only the people that have access to the original weights (from completely legal sources, of course) can transform them into finetuned weights. You can find the decrypt code on https://github.com/LianjiaTech/BELLE/tree/main/models .

Model description

8 bits quantization of BELLE-LLAMA-7B-2M using GPTQ

GPTQ is SOTA one-shot weight quantization method.

The code of inference can be found in our Github project repository: https://github.com/LianjiaTech/BELLE/tree/main/gptq.

Basically, 8-bit quantization and 128 groupsize are recommended.

This code is based on GPTQ-for-LLaMa

  1. Decrypt the files using the scripts in https://github.com/LianjiaTech/BELLE/tree/main/models

You can use the following command in Bash. Please replace "/path/to_encrypted" with the path where you stored your encrypted file, replace "/path/to_original_llama_7B" with the path where you stored your original llama7B file, and replace "/path/to_finetuned_model" with the path where you want to save your final trained model.

mkdir /path/to_finetuned_model
for f in "/path/to_encrypted"/*; \
    do if [ -f "$f" ]; then \
       python3 decrypt.py "$f" "/path/to_original_llama_7B/consolidated.00.pth" "/path/to_finetuned_model/"; \
    fi; \

After executing the aforementioned command, you will obtain the following files.

  1. Check md5sum

You can verify the integrity of these files by performing an MD5 checksum to ensure their complete recovery. Here are the MD5 checksums for the relevant files:

There still exists a few issues in the model trained on current base model and data:

  1. The model might generate factual errors when asked to follow instructions related to facts.

  2. Occasionally generates harmful responses since the model still struggles to identify potential harmful instructions.

  3. Needs improvements on reasoning and coding.

Since the model still has its limitations, we require developers only use the open-sourced code, data, model and any other artifacts generated via this project for research purposes. Commercial use and other potential harmful use cases are not allowed.
