These are GPTQ 4bit model files for VMWare's XGEN 7B 8K Open Instruct .

It is the result of quantizing to 4bit using GPTQ-for-LLaMa.

How to use this GPTQ model from Python code

First, make sure you have AutoGPTQ installed:

pip install auto-gptq

Second, install tiktoken in order to use the tokenizer

pip install tiktoken

print(f"\n\n {tokenizer.decode(output[0]).split('### Response:')[1]}")
