Quantization for PMs: Cheaper, Faster Models and Where the Quality Goes
Quantization represents model weights (and sometimes activations) with fewer bits, cutting memory, cost and latency. This guide explains the precision options, what a large 2024 study found about quality at 8 and 4 bits, why small models and certain tasks lose more, how to evaluate on your workload, and the product decisions quantization enables.
