Weight Quantization in Large Language Models: How GPTQ, AWQ, and SmoothQuant Compress Neural Networks
Weight Quantization in Large Language Models: How GPTQ, AWQ, and SmoothQuant Compress Neural Networks Serving large language models in production requires balancing GPU memory footprint, memory bandwidth limits, and computational throughput. A standard 70-billion parameter transformer stored in 16-bit floating-point (FP16 or BF16) requires roughly 140 gigabytes of high-bandwidth memory (HBM) merely to hold its parameters. This memory footprint exceeds the capacity of a single 80GB GPU before ac
