Ex-OpenAI researcher claims forensic proof Chinese labs trained on banned Blackwell chips

Former OpenAI researcher Will Depue claims 'conclusive forensic evidence' that the top 4 Chinese AI labs—DeepSeek, Moonshot, MiniMax and Ant Group—built their newest models on NVIDIA Blackwell chips barred from export to China. His method: a model's initial weight layout depends on the exact GPU and seed, leaving a hardware 'fingerprint' that survives training into the released model. The claim is self-reported and unverified, but is drawing wide attention.
