DeepSeek Open-Sources Full Ascend Stack, Mirroring NVIDIA's
On September 30, 2026, DeepSeek open-sourced its full Ascend infrastructure stack for Huawei chips — operators, comms and tooling mapped one-to-one against NVIDIA's CUDA platform.
Highlights
- Drop-in migration path from NVIDIA tooling
- Enables frontier-scale training on domestic silicon
- Comes after reports that new models cut HBM requirements to about a quarter
It extends DeepSeek's open-source strategy from model weights (MIT) down to the full training infrastructure layer.
