SoScale method improves FP4 quantization accuracy for LLMs

By PulseAugur Editorial · [1 sources] ·

Researchers have developed SoScale, a novel method for second-order scale search in FP4 quantization of large language models. This technique aims to improve the accuracy of FP4 quantization, which is crucial for reducing memory footprint and inference costs. SoScale optimizes scale codes based on their impact on layer outputs, rather than just local reconstruction error, and integrates with GPTQ-style error recovery. Experiments on Qwen3 models show that SoScale consistently reduces quantization degradation across various FP4 formats like MXFP4, NVFP4, and HiF4. AI

IMPACT This research could lead to more efficient LLM deployment by reducing memory and computational requirements.

    SoScale: Second-Order Scale Search for FP4 Quantization

    arXiv:2611.16426v1 Announce Type: cross Abstract: Low-bit quantization reduces the memory footprint and inference cost of large language models (LLMs), yet accurate FP4 quantization remains challenging. Practical formats such as MXFP4, NVFP4, and HiF4 pair a 4-bit floating-point …
