HiFloat4 Format for Language Model Pre-training on Ascend NPUs

Researchers at Huawei have introduced HiFloat4, a new 4-bit floating-point format for language model pre-training on Ascend NPUs, achieving up to four times improvement in compute throughput and memory efficiency compared to higher-precision methods. This development is crucial for developers seeking to reduce computational costs while maintaining performance in large-scale models. Further research will focus on optimizing stabilization techniques for FP4 training across various model architectures.
