[WASHINGTON] US Treasury Secretary Scott Bessent and Federal Reserve chair Jerome Powell convened an urgent meeting with bank CEOs on Tuesday (Apr 7) to warn of the cyber risks posed by Anthropic’s latest artificial intelligence model, two sources said on Thursday.
The company launched the Mythos model on Tuesday but stopped short of a broad release, citing concerns it could expose previously unknown cybersecurity vulnerabilities.
Anthropic has said the model is capable of identifying and exploiting weaknesses in “every major operating system and Web browser”.
Last week, it shared that it was in ongoing discussions with US government officials about the model’s “offensive and defensive cyber capabilities”.
A third source close to the matter reiterated Anthropic’s outreach, saying the company proactively briefed senior US government officials and key industry stakeholders on Mythos’ capabilities ahead of its release.
The Treasury-hosted meeting in Washington on Tuesday was aimed at ensuring banks are aware of the risks posed by Mythos and similar models, and are taking steps to defend their systems, one of the sources said.

Invitations were sent while most CEOs of the largest US banks were already in Washington to attend other meetings, a source noted.
Access to Mythos will be limited to about 40 technology companies, including Microsoft and Google, the startup has said.
Bloomberg News, which first reported the matter on Thursday, noted that the CEOs of Citigroup, Morgan Stanley, Bank of America, Wells Fargo and Goldman Sachs were present.
JPMorgan CEO Jamie Dimon was unable to join, one of the sources told Reuters. Goldman Sachs, Wells Fargo and the Federal Reserve declined to comment.
