Vance, Bessent questioned tech giants on AI security before Anthropic's Mythos release

The meeting occurred over the phone, according to a person familiar with the matter who asked not to be named because the meeting was private.

The person said that Anthropic's Dario Amodei, Google's Sundar Pichai, OpenAI's Sam Altman, Microsoft's Satya Nadella, CrowdStrike's George Kurtz and Palo Alto Networks' Nikesh Arora also participated.

The tech CEOs met to discuss the security posture of large language models and safe deployment, according to the person. Officials also discussed how to respond if models scale in favor of attackers, they added.

OpenAI declined to comment on the meeting. CNBC has reached out to the White House and the other companies for comment.

An Anthropic official declined to comment on the meeting, but told CNBC Friday that the company has been in touch with White House officials about cybersecurity in recent weeks and has made itself available to support "the government's own testing and evaluation of the technology."
