The National Security Agency is quietly integrating Anthropic’s Mythos Preview into its cyber‑defense arsenal, according to reporting by Axios. Mythos, announced earlier this month as a frontier model built for cybersecurity tasks, never saw a public rollout. Anthropic cited the model’s potential for offensive cyber operations as the reason for restricting its release, and instead offered access to a select group of about 40 organizations.

Among those privileged recipients, the NSA appears to be a key player. Agency officials are reportedly using Mythos primarily to scan networks and systems for exploitable vulnerabilities, a capability that aligns with the model’s design focus on threat detection and mitigation. The United Kingdom’s AI Security Institute has also confirmed it holds access to the model, underscoring the limited but high‑profile nature of Mythos’s early user base.

The NSA’s adoption arrives on the heels of a public dispute between Anthropic and the Pentagon. The Department of Defense labeled the AI firm a "supply chain risk" after Anthropic balked at granting Pentagon officials unrestricted access to its full‑capability models. The friction grew when Anthropic refused to make its Claude system available for mass domestic surveillance and autonomous weapons development, prompting the DoD to question the firm’s reliability as a defense supplier.

Despite the tension, Anthropic’s relationship with the current administration shows signs of improvement. Last Friday, CEO Dario Amodei met with White House chief of staff Susie Wiles and Treasury Secretary Scott Bessent. Sources said the meeting was productive, hinting at a possible easing of the earlier standoff. Anthropic declined to comment on the specifics of the NSA’s usage, and TechCrunch’s request for a comment from the agency went unanswered.

Mythos’s limited distribution raises questions about how the government balances the need for cutting‑edge AI tools with concerns over security and control. By restricting the model to a handful of vetted partners, Anthropic aims to mitigate the risk of its technology being weaponized while still offering a powerful resource to allies deemed trustworthy. The NSA’s involvement suggests the agency values the model’s advanced scanning capabilities enough to navigate the surrounding controversy.

Industry observers note that the episode reflects a broader trend of U.S. intelligence and defense agencies turning to private‑sector AI innovators for specialized tools. As AI models become more capable, the line between defensive and offensive applications blurs, prompting agencies like the NSA to seek solutions that can keep pace with evolving cyber threats. Anthropic’s cautious rollout of Mythos may serve as a template for future collaborations, where access is granted on a need‑to‑know basis rather than through open releases.

While the NSA’s use of Mythos remains largely under the radar, the development signals a shift in how the intelligence community approaches AI‑driven cybersecurity. The model’s ability to quickly identify vulnerabilities could accelerate threat remediation and strengthen national cyber defenses, even as policymakers grapple with the ethical and security implications of deploying such powerful technology.
