Huawei HiFloat4 Outperforms MXFP4 On Ascend Chips
Huawei's HiFloat4 training format outperformed Western-developed MXFP4 in recent Ascend chip benchmarks. This development suggests that US export controls are accelerating Chinese innovation in custom numerical formats. Hardware engineers should monitor these efficiency gains. The shift reduces reliance on standard Western precision formats for large-scale model training.
