Quantization formats compared: GGUF vs GPTQ vs AWQ vs NF4
The article compares four major LLM weight quantization formats: GGUF, GPTQ, AWQ, and NF4. Quantization is crucial for reducing model size to fit within limited hardware constraints, such as consumer GPUs or unified memory systems. Each format offers different trade-offs between memory footprint, inference speed, and accuracy, making them suitable for specific deployment scenarios. AI
