Huawei HiFloat4 Outperforms MXFP4 on Ascend Chips
Huawei's HiFloat4 training format outperformed Western-developed MXFP4 in recent Ascend chip benchmarks. This technical win suggests that US export controls are accelerating China's internal development of specialized numerical formats. Practitioners should monitor these efficiency gains as they may reduce the hardware gap for large-scale model training in restricted markets.
