DeepSeek open-sources Ascend infrastructure components with Huawei
On September 30, 2026, DeepSeek announced it had open-sourced a set of infrastructure components for Huawei's Ascend compute platform, including an Ascend version of its TileLang compiler as well as DeepGEMM-Ascend, DeepEP-Ascend, TileKernels, FlashMLA and DeepSelect. DeepSeek said the releases mirror its earlier Nvidia-oriented open-source components one-for-one and that every TileLang operator used to train its V4 model family now has a corresponding high-performance Ascend implementation. The company said it worked closely with Huawei to jointly optimize compute and communication on a 128-chip Ascend 950 supernode, advancing a domestic alternative to Nvidia's CUDA ecosystem.
