Former OpenAI researcher says he found Nvidia Blackwell fingerprints hidden inside six Chinese AI models
AI summary
1-flash. The method exploits the random seed pattern PyTorch uses to initialize weights, which reflects a GPU's core count: 148 cores for B200/B300 and 152 for GB200/GB300, versus 132 for Hopper H100/H800. DePue says he reproduced the results for DeepSeek-V4-Flash and Kimi K3 on real Blackwell chips, published verification code on GitHub, and that the method correctly identified all 24 control models with known hardware.
