April 9 (Reuters) – U.S. Treasury Secretary Scott Bessent and Federal Reserve Chair Jerome Powell convened an urgent meeting with bank ‌CEOs this week to warn of cyber risks posed by Anthropic’s ‌latest AI model, two sources familiar with the matter said on Thursday.

Anthropic launched the powerful Mythos ​model earlier this week but stopped short of a broad release, citing concerns it could expose previously unknown cybersecurity vulnerabilities.

The company has said the model is capable of identifying and exploiting weaknesses across “every major operating system and every major ‌web browser”.

Last week, Anthropic said ⁠it was in ongoing discussions with U.S. government officials about the model’s “offensive and defensive cyber capabilities.”
