AWQ: On-Device LLM Compression and Acceleration

This July 2024 paper introduces Activation-aware Weight Quantization (AWQ), a novel method for compressing Large Language Models (LLMs) by quantizing weights to low-bit integers for efficient deployment on edge devices. It highlights that AWQ identifies and protects crucial "salient" weights by observing activation distributions, which significantly reduces quantization error without requiring computationally intensive training or overfitting to specific datasets. Complementing AWQ, the paper also presents TinyChat, an inference framework specifically designed to optimize and accelerate these 4-bit quantized LLMs on various hardware, including mobile GPUs and even resource-constrained devices like the Raspberry Pi, achieving substantial speedups compared to traditional implementations. The combination of AWQ and TinyChat aims to make powerful LLMs accessible for on-device applications, addressing challenges like memory limitations and power consumption.Source:https://arxiv.org/pdf/2306.00978
