NSA Utilizes Anthropic’s Mythos Model Amid Pentagon Dispute

NSA uses Anthropic's Mythos model amid Pentagon dispute.

The United States National Security Agency (NSA) is employing the much-discussed Mythos model from Anthropic, despite the startup’s conflict with the Pentagon. This was reported by Axios, citing sources.

Previously, disagreements arose between Anthropic and the Pentagon due to the company’s reluctance to allow the use of AI models for mass surveillance of U.S. citizens and the development of autonomous weapons. Consequently, President Donald Trump instructed all federal agencies to completely cease using the AI firm’s technologies within six months.

In April, Anthropic developed a new model, Claude Mythos, but refrained from releasing it publicly due to high security risks. During several weeks of testing, the neural network identified thousands of zero-day vulnerabilities in major operating systems and web browsers.

Instead of a public release, the company launched Project Glasswing—an initiative involving AWS, Apple, Broadcom, Cisco, CrowdStrike, Google, JPMorgan Chase, Linux Foundation, Microsoft, Nvidia, Palo Alto Networks, and others to test the tool in secure environments.

Axios discovered that the NSA is among the undisclosed recipients of the technology. It is unknown how the agency utilizes the startup’s artificial intelligence, but others use it to scan their own environments for vulnerabilities.

“Currently, the military is expanding the use of Anthropic’s tools while simultaneously claiming in court that their application threatens U.S. national security,” the journalists noted.

Relations between Anthropic and the authorities seem to have warmed. On April 18, the company’s CEO, Dario Amodei, discussed potential collaboration opportunities with administration representatives.

The meeting was attended by White House Chief of Staff Susie Wiles and Treasury Secretary Scott Bessent.

Earlier in April, Anthropic released an environment for running complex and long-term agent tasks—Claude Managed Agents.
