This is the official PyTorch implementation of QLLM: Accurate and Efficient Low-Bitwidth Quantization for Large Language Models.

By Jing Liu, Ruihao Gong, Xiuying Wei, Zhiwei Dong, Jianfei Cai, and Bohan Zhuang.

qllm

We propose QLLM, an accurate and efficient low-bitwidth post-training quantization method designed for LLMs.

📰 News

  • [10-03-2024] Release the code!🌟
  • [17-01-2024] QLLM is accepted by ICLR 2024! 👏

📖 Contents

🛠 Install

conda create -n qllm python=3.10 -y
conda activate qllm
git clone https://github.com/ModelTC/QLLM
cd QLLM
pip install --upgrade pip 
pip install -e .

⚙️ Usage

We provide the training scripts in scripts folder. For example, to perform W4A8 quantization for LLaMA-7B, run

sh scripts/llama-7b/w4a4.sh

Remember to change the path of model model and output path output_dir.

📋 Results

  • QLLM achieve SoTA performance in weight-activation quantization
