Forensic claim: top Chinese labs trained newest models on export-banned Blackwell GPUs

felipesuch · x · 2026-11-13

Developer felipesuch claims to have 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: nearly every AI model carries a hidden signature of the GPU that trained it — he notes these labs used plain torch.randn for initialization instead of a custom GPU- and shard-agnostic method, making the training hardware traceable from the weights. The claim is unverified personal analysis, but would be significant if confirmed.
