Quantization
The process of reducing the numerical precision of a model's weights, typically from 16-bit or 32-bit floating point down to 8-bit, 4-bit, or even lower.
In depth
The process of reducing the numerical precision of a model's weights, typically from 16-bit or 32-bit floating point down to 8-bit, 4-bit, or even lower. Quantization dramatically reduces model size and memory usage, making it possible to run large models on consumer GPUs and edge devices. The trade-off is a small loss in output quality, though modern quantization techniques like GPTQ and AWQ minimize this gap.
