Will DePue, a former researcher at OpenAI, has presented what he claims is the first technical proof that multiple Chinese AI models are utilizing Nvidia’s Blackwell GPUs, despite existing U.S. export restrictions. His forensic analysis involved examining model weights to identify unique chip signatures associated with Nvidia’s technology.
This revelation not only underscores the challenges of enforcing export controls but also raises significant national security concerns. The estimated cost of the hardware used in these models exceeds half a billion dollars, prompting discussions about the implications for U.S.-China relations in the burgeoning AI arms race.
