DeepSeek opens source infrastructure components for Huawei ascend platform

On September 30, 2026, DeepSeek officially released open-source infrastructure components tailored for Huawei's Ascend platform, including TileLang, a high-level language compiler, along with compute and distributed communication libraries. These components mirror those previously made available for NVIDIA platforms. TileLang, designed to be simpler than NVIDIA's CUDA, enhances development efficiency and simplifies code logic. It is already integral to the training of DeepSeek V4 models, enabling high-performance operations. The Ascend version of TileLang preserves hardware performance while offering a higher-level programming interface. The release includes multiple repositories, each focusing on different components such as DeepGEMM, DeepEP, and TileKernels.
