US security agency is using Anthropic's Mythos despite blacklist

The US National Security Agency is reportedly using Anthropic's advanced AI tool, Mythos Preview. This comes even after the Pentagon flagged the company for supply-chain risks. The AI model is said to be highly capable in coding and autonomous tasks. Experts suggest its abilities could significantly enhance cyberattack capabilities. Discussions between the US administration and Anthropic have also taken place.

The United States National Security Agency is using Anthropic's Mythos Preview AI tool despite the Pentagon hitting the company with a formal supply-chain risk designation, Axios reported on Sunday.

The Mythos Preview model was ⁠being used ⁠more widely within the department, Axios said, citing sources. Reuters could not immediately verify the report.

Anthropic, the NSA and the Department of Defense did not immediately respond to requests for comment outside regular business hours. The ⁠NSA is part of the Defense Department.

Last week, U.S. President Donald Trump's administration and ⁠Anthropic's CEO discussed working together for the first time since a dispute earlier this year between the Pentagon and the AI firm over how that company's models should be used.
