Huawei HiFloat4 Outperforms MXFP4 On Ascend Chips
Huawei's HiFloat4 training format outperformed Western-developed MXFP4 in recent Ascend chip benchmarks. This performance gap suggests that US export controls are accelerating Chinese development of proprietary numerical formats. The shift optimizes hardware efficiency for local silicon. Practitioners should monitor how these custom formats affect cross-platform model portability and training stability.
