DeepSeek Open-Sources Infrastructure Components for Huawei Ascend Compute Platform, Matching Its Nvidia Offerings One-for-One
Summary
On September 30, DeepSeek announced via its official WeChat account that it has open-sourced infrastructure components for Huawei's Ascend compute platform, including the TileLang high-level language compiler, compute libraries and distributed communication libraries, all matching one-for-one its earlier open-source components for Nvidia platforms. DeepSeek says every TileLang operator used in its training now has a corresponding high-performance implementation on Ascend, with compute and communication performance approaching hardware limits in several key benchmarks.
Bubble analysis
This item carries no investment figures, valuations or capex, so it neither proves nor disproves an AI bubble. Its significance is indirect: a leading Chinese model company is moving its software stack from Nvidia's ecosystem to Huawei Ascend, which could weaken Nvidia's long-run China revenue outlook and reduce Chinese AI training's reliance on imported compute — but only follow-on procurement and capex data can settle that.
