Will DePue, a former OpenAI researcher who leads Unemployment Labs, analysed openly released model weights from DeepSeek, Moonshot AI, MiniMax and Ant Group. According to TechCrunch, he found evidence of Blackwell training configurations in models including DeepSeek V4 and Moonshot AI Kimi K3.
Nvidia Blackwell GPUs are restricted from export to China or Chinese-owned firms. The report notes that the chips could have been located in an offshore data centre, rather than in China.
For companies building with these AI models, the research offers a view into the computing infrastructure behind them. It also highlights a distinction worth keeping when assessing suppliers: a model developer's home country does not necessarily reveal where its training hardware operates.
