Forensic analysis claims top 4 Chinese AI labs trained on export-banned NVIDIA Blackwell chips

Will Depue claims "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.
The method: a model's initial weight layout depends on the exact GPU, so each GPU+seed combination leaves a hardware fingerprint that survives training into published weights. Analysis of publicly released weights — no insider leaks — allegedly reveals the training hardware.
Unverified independent claim, but if confirmed it would undermine US chip export controls.
