Huawei HiFloat4 Outperforms MXFP4 On Ascend Chips
Huawei's HiFloat4 training format beat Western-developed MXFP4 in recent Ascend chip performance tests. This development suggests that US export controls are accelerating China's internal hardware optimization. The shift forces a divergence in training standards. Practitioners should monitor how these proprietary formats impact cross-platform model portability and hardware efficiency.
