- DeepSeek open sourced Ascend ports of its production kernel and communication libraries with Huawei’s support in tow
- Published benchmarks ran on a proof-of-concept hardware kit DeepSeek says is not a publicly distributed release
- Two repositories are genuinely new and have received hundreds of GitHub stars versus Nvidia’s thousands; the other announced components are updates to existing tools

DeepSeek published two completely new repositories, DeepGEMM-Ascend for matrix multiplication and DeepEP-Ascend for the all-to-all communication that mixture-of-experts models depend on.
