Will DePue of Unemployment Labs examined model weights from DeepSeek, Moonshot AI, MiniMax, and Ant Group, spotting numerical patterns that match NVIDIA's advanced Blackwell GPUs, including high-end GB200 and GB300 variants. Six models released since April 2026 showed these fingerprints, while earlier ones aligned with older Hopper chips; tests on real hardware reproduced the weights bit-for-bit, with matches reaching extreme statistical confidence like 1,385 sigma. The analysis estimates clusters of 2,000 to 3,000 GPUs per run, amid scrutiny of NVIDIA's China ties following CEO Jensen Huang's recent departure. Though it doesn't prove smuggling—rentals abroad remain possible—the findings highlight open model releases as a new source for tracking restricted AI hardware access.
