Anthropic's Mythos AI model found vulnerabilities in classified US government systems, official says

A U.S. official revealed that one of Anthropic's artificial intelligence models, Mythos, identified vulnerabilities in highly sensitive U.S. government computer systems during a testing exercise. The model found these flaws within hours, though it's not confirmed if it could exploit them. The administration recently directed Anthropic to prevent foreign nationals from using its advanced AI models, Fable 5 and Mythos 5, due to cybersecurity concerns.
