New OSFP4 quantization scheme boosts LLM inference accuracy

Researchers have developed a new quantization scheme called OSFP4, designed to improve the accuracy of NVFP4 data types for large language model (LLM) inference. OSFP4 optimizes diagonal smoothing matrices and block scales to minimize quantization errors, outperforming existing methods in accuracy across various settings. This new scheme maintains a significant portion of the vendor NVFP4 prefill throughput, making it an attractive option for efficient LLM deployment. AI

IMPACT Optimizes LLM inference efficiency and accuracy, potentially enabling wider deployment of larger models on less powerful hardware.

    OSFP4: Joint Optimization of Diagonal Smoothing and Block Scales for NVFP4 Quantization

    arXiv:2610.08231v1 Announce Type: new Abstract: NVFP4 is an attractive datatype for large language model (LLM) inference, offering compact storage and native tensor-core acceleration. However, preserving accuracy using NVFP4 requires careful quantization. In this work we develop …
