DeepSeek open-sources full Ascend AI training stack, mirroring its NVIDIA components

aigclink · x · 2026-09-30

DeepSeek has open-sourced the entire in-house infrastructure stack it built for training its V4-series models, ported from NVIDIA GPUs to Huawei Ascend chips.

The stack powers most of the operators used in V4 training and includes the TileLang kernel DSL, the DeepGEMM matrix computation library, the DeepEP distributed communication library, plus TileKernels, FlashMLA, and DeepSelect — each component has a one-to-one NVIDIA counterpart. It marks the first time a full, open training stack of this scope is available for Ascend hardware.
