What Is Model Quantization? How Lower Precision Makes AI Faster and Cheaper
📌 概要
本文介绍模型量化技术：通过用更少比特表示模型权重、激活值或缓存值，降低内存占用、存储需求与能耗，并通常能缩短推理延迟。文章讲解了量化的工作机制、精度与性能的权衡取舍、效果评估方法及实际部署中的关键控制手段。
⚡ 关键要点
- ▸量化以更少比特表示权重、激活或缓存值
- ▸可减少内存流量、存储、能耗与推理延迟
- ▸需权衡精度损失并做好评估与控制
Model quantization represents model weights, activations, or cache values with fewer bits to reduce memory traffic, storage, energy, and often inference latency. This guide explains the mechanism, trade-offs, evaluation, and controls that matter in practice.
