Huawei HiFloat4 Outperforms MXFP4 In Chip Tests
Huawei's HiFloat4 training format beat the Western-developed MXFP4 standard during tests on Ascend chips. This performance gap suggests that US export controls are accelerating Chinese innovation in custom numerical formats. Engineers can expect more specialized hardware optimizations as China seeks independence from Western silicon standards to maintain training efficiency.
