Forensic report links six Chinese AI models to Nvidia Blackwell GPUs

Unemployment Labs, a lab led by Will DePue, published a forensic analysis of publicly released model weights that it says shows six frontier models from DeepSeek, Moonshot AI, MiniMax and Ant Group were initialized on Nvidia Blackwell GPUs, hardware restricted from export to China. Earlier models from the same labs match Hopper-generation chips instead, the report says. The method recovers each model's random seed and thread layout from its preserved weights; the author says the matches were reproduced on physical H100, B300 and GB200 chips, and that reproduction scripts and test outputs are available to reviewers on request. The report estimates each training run required roughly 500 to 3,000 Blackwell GPUs over two to three months. The report states its evidence comes entirely from the models' published weights and provides technical evidence of access to advanced hardware, but does not establish where the chips were located, how access was obtained, or whether export controls were violated.
