A visualization of INT4 weight tensors being dequantized and multiplied in a fused GEMM kernel

Build a Blockwise INT4 Inference Engine: A Hands-On Portfolio Project

A hands-on build guide for a blockwise INT4 inference engine with packed-nibble weights, per-group scales/zero-points, and fused dequantizing GEMM — a portfolio project that demonstrates real systems and ML engineering depth.
