You can quantize large language models to 4-bit precision using GPTQ to achieve a 4× memory reduction. This post-training quantization process uses group-wise scaling to compress model weights while preserving accuracy for consumer GPU inference.
GPTQ quantization supports major model families including Llama, Mistral, Qwen, Phi, Yi, Falcon, BLOOM, and OPT. It integrates directly with AutoGPTQ and transformers to ensure broad compatibility across popular large language models.
Yes, you can use PEFT and QLoRA fine-tuning on a 4-bit quantized model. GPTQ integrates with the peft library to enable parameter-efficient fine-tuning workflows directly on the quantized weights.
The best way to deploy large 70B to 405B scale models on consumer GPUs is through 4-bit GPTQ post-training quantization. This approach dramatically reduces the memory footprint while maintaining model accuracy for faster inference.
You need to install AutoGPTQ, transformers, optimum, and peft to perform 4-bit GPTQ model quantization. These dependencies provide the calibration, integration, and troubleshooting references required for end-to-end deployment.
