Developer claims GPU fingerprint evidence shows top Chinese labs trained on banned Blackwell chips

Developer willdepue says he found 'conclusive forensic evidence' that DeepSeek, Moonshot, MiniMax and Ant Group built their newest models on NVIDIA's Blackwell chips, which are barred from export to China. His method relies on the observation that almost every AI model carries a hidden signature of the GPU that trained it, detectable from the model's initialization. Researcher Dimitris Papail amplified the thread, calling it 'artisanal science' investigative work. The claim is unverified and touches on US–China export controls; follow-up discussion noted alternative explanations (e.g., faked inits, or initializing on one hardware and training on another) remain plausible.
