## Summary

DeepSeek released Ascend support for six of its open-source repositories, including TileLang, DeepGEMM, DeepEP, and FlashMLA, in a trade where Huawei supplies hardware and DeepSeek supplies models and workloads. SemiAnalysis benchmarks the Ascend 950PR, finding its best BF16 GEMM kernels reach 99.7% of the ceiling, while its memory bandwidth reaches 1.6384 TB/s. It also reports that most of the software works only on supernodes, with several issues remaining on x86 hosts.

## Why it matters

The article shows how DeepSeek's kernel work and Huawei's chip stack depend on each other, with benchmarks and an execution profile showing where the gains and remaining gaps are.
