Huawei HiFloat4 Outperforms MXFP4 on Ascend Chips
Huawei's HiFloat4 training format outperformed the Western-developed MXFP4 standard during tests on Ascend hardware. This efficiency gain suggests that US export controls are accelerating China's development of independent numerical formats. Hardware engineers must now track divergent standards as Huawei optimizes its silicon stack to bypass external dependencies and maintain competitive training speeds.
