Synopsis
The meeting, held at the Treasury Department in Washington on Tuesday, was aimed at ensuring banks are aware of the potential risks posed by Mythos and similar models, and are taking steps to defend their systems. Access to Mythos will be limited to about 40 technology companies, including Microsoft and Google, and Anthropic has been in ongoing talks with the US government about the model's capabilities, the startup has said.White House national economic adviser Kevin Hassett confirmed the meeting during an interview with Fox News' "The Story with Martha MacCallum."
"Those bankers were in town for meetings that day, and it was appropriate (for) the Secretary Bessent to do what he did. He brought them over to the Treasury, along with Jay Powell, and went through the cyber risks to make sure that they were aware of them," Hassett said, adding that the Trump administration is taking steps to ensure the public is safe from potential risks.
Anthropic launched the powerful Mythos model 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 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.
