Huawei HiFloat4 Outperforms MXFP4 In Chip Tests
Huawei's HiFloat4 training format beat Western-developed MXFP4 during tests on Ascend chips. This performance gain suggests that US export controls are accelerating Chinese development of independent numerical formats. The shift reduces reliance on Western hardware standards. Practitioners should monitor these proprietary formats as they impact cross-platform model portability and training efficiency.
