LLMs Quantization Recipes

Intel® Neural Compressor supported advanced large language models (LLMs) quantization technologies including SmoothQuant (SQ) and Weight-Only Quant (WOQ), and verified a list of LLMs on 4th Gen Intel® Xeon® Scalable Processor (codenamed Sapphire Rapids) with PyTorch, Intel® Extension for PyTorch and Intel® Extension for Transformers.
This document aims to publish the specific recipes we achieved for the popular LLMs and help users to quickly get an optimized LLM with limited 1% accuracy loss.
