unemploymentlabs.com/checkpoint-forensics Chinese frontier AI models carry the fingerprint of export-controlled GPUs
Forensic analysis of published model weights found six models from DeepSeek, Moonshot AI, MiniMax and Ant Group matching NVIDIA Blackwell hardware, suggesting these Chinese labs trained recent models on export-restricted chips. The report cautions the evidence supports but does not prove that inference and does not establish chip location, access route or whether controls were violated.
