Unlocking AI’s Hidden Power: The Secret Magic of Model Quantization

Chay published on 2025-06-27 included in AI

Quantization in Artificial Intelligence (AI) is a crucial technique that optimizes neural networks by reducing the precision of the numerical representations of their internal components, primarily weights and activations. Instead of using high-precision floating-point numbers like 32-bit floats (FP32), quantization converts them to lower-precision formats such as 8-bit integers (INT8), 16-bit floats (FP16), or even as low as 4-bit integers (INT4) or binary (1-bit). Purpose and Benefits of Quantization The main reasons for using quantization are:
