Huawei HiFloat4 Outperforms MXFP4 in Chip Tests
Huawei's HiFloat4 training format beat the Western-developed MXFP4 during tests on Ascend chips. This performance gain suggests that US export controls are accelerating Chinese domestic innovation in specialized hardware formats. The result provides a concrete alternative for high-efficiency training. Practitioners should monitor how these proprietary formats impact cross-platform model portability.
