Huawei HiFloat4 Outperforms MXFP4 on Ascend Chips
Huawei's HiFloat4 training format outperformed the Western-developed MXFP4 standard during tests on Ascend chips. This performance gap suggests that US export controls are accelerating China's development of independent hardware optimizations. Engineers can expect a divergence in training standards as Chinese firms pivot away from global norms to maximize local silicon efficiency.
