Title: MicroMix: Efficient Mixed-Precision Quantization with Microscaling Formats for Large Language Models

Abstract:
arXiv:2508.02343v2 Announce Type: replace-cross Abstract: Quantization significantly accelerates inference in large language models (LLMs) by replacing original high-precision matrices with low-precision counterparts. Recent advances in weight-activation quantization have primarily focused on mapping both weights and activations to the INT4 format. Although the new FP4 Tensor Cores in NVIDIA's Blackwell architecture offer up to 4x speedup over FP16, existing INT4-based kernels fail to fully expl
