gptq
About
GPTQ is a 4-bit post-training quantization technique for LLMs that enables 4x memory reduction and 3-4x faster inference with minimal accuracy loss. It's ideal for deploying large models on consumer GPUs and integrates with transformers and PEFT for QLoRA fine-tuning. Use it when you need to fit 70B+ parameter models on limited hardware while maintaining performance.
