Key point

The NSA is reportedly using Mythos Preview despite it being on the DoD's Anthropic blacklist.

Details

The NSA has reportedly been using Anthropic's latest model, Mythos Preview.

This directly clashes with the situation where its parent agency, the Department of Defense (DoD), has designated Anthropic a supply chain risk and sought to block it. The dispute has now escalated into a court battle.

According to reports, access to Mythos has been limited to about 40 organizations, of which Anthropic officially disclosed only 12. The other organizations with access are said to be mainly using the model for security tasks such as vulnerability scanning within their own environments.

Also, Anthropic CEO Dario Amodei met with White House officials on Friday to discuss government use of Mythos and security policy. UK intelligence agencies are also reported to have access through their own AI Security Institute.
