GPTQ vs AWQ vs NF4: Choosing the Right LLM Quantization Pipeline

Mar 12 · 15 min read · TLDR: GPTQ, AWQ, and NF4 all shrink LLMs, but they optimize different constraints. GPTQ focuses on post-training reconstruction error, AWQ protects salient weights for better quality at low bits, and NF4 offers practical 4-bit compression through bit...
