Forensic evidence claimed: top Chinese AI labs trained on export-banned Blackwell GPUs

Will Depue claims "conclusive forensic evidence" that DeepSeek, Moonshot, MiniMax, and Ant Group built their newest models on NVIDIA's export-banned Blackwell chips. The method: initial weight layouts depend on the specific GPU-seed combination, leaving a detectable hardware fingerprint that survives training. Quoter RoyalCities, who says he has sold B200s/300s, adds that despite KYC under export controls, a 2T-parameter model at bf16 is small enough to train in a friendly country and deploy in China from a single 4TB SSD.
