The Fed rang the alarm about Anthropic's Mythos AI model — but had to go months without it

In April, the Federal Reserve and Treasury Department warned that Anthropic's Claude Mythos Preview (an AI model designed to find security weaknesses in software) could pose a cybersecurity threat to major financial institutions, yet the Fed itself lacked access to the model for at least three months afterward. As of July, Federal Reserve Chairman Kevin Warsh testified he was still working to secure access to Mythos and other advanced AI models so the Fed and banking system could identify and patch their own vulnerabilities.
