Developer claims GPU fingerprinting reveals top Chinese labs trained on Blackwell chips
terryyuezhuo · x · 2026-11-13
Will Depue says he found 'conclusive forensic evidence' that DeepSeek, Moonshot, MiniMax and Ant Group built their newest models on NVIDIA's most advanced Blackwell chips, which are barred from export to China. His method: weight initialization patterns depend on the exact GPU, and each GPU+seed combination leaves a unique hardware fingerprint that survives training into the published model — a hidden signature of the training hardware. The claim is unverified; quote-tweets quip that Chinese models are 'a great use of NVIDIA GPUs.'
