LLM Weight Quantization in Production: Ensuring Quality and Throughput with Calibration Fingerprints, Kernel Compatibility Matrices, and Dual-Track Replay
A deep dive into the complete pipeline for deploying LLM weight quantization from experimentation to production, covering AWQ/GPTQ algorithm comparisons, calibration set fingerprinting, a four-layer compatibility model, kernel compatibility matrices, dual-track quality and throughput replay, and canary release/rollback strategies.
