Research group publishing checkpoint-forensics analysis that infers training hardware from public weights.
Former OpenAI researcher Will DePue claims a forensic analysis uncovered technical fingerprints of Nvidia's export-controlled Blackwell GPUs inside models from six Chinese AI labs, including DeepSeek, Moonshot AI, MiniMax and Ant Group. He says the evidence shows access to the latest Nvidia hardware but does not by itself prove smuggling or a legal violation, since capacity could be rented at overseas data centers.
A forensic analysis by Unemployment Labs of publicly released model weights finds that six models from DeepSeek, Moonshot AI, MiniMax and Ant Group since April 2026 carry numerical fingerprints matching NVIDIA's Blackwell GPUs, while their earlier models match the prior Hopper generation. The evidence derives entirely from the models' own weights rather than leaks, and was confirmed on physical Blackwell hardware for DeepSeek-V4-Flash and Kimi K3, offering reproducible technical evidence relevant to export-control enforcement.
