Despite an ongoing dispute between Anthropic and the Pentagon, the National Security Agency (NSA) is reportedly using Anthropic’s new Mythos Preview AI model. This information comes from Axios, which spoke to two sources familiar with the situation. The news suggests a complicated relationship between the AI company and various parts of the U.S. government.
Anthropic unveiled Mythos Preview in early April, describing it as a versatile language model “strikingly capable at computer security tasks.” However, back in February, President Trump issued an order instructing all government agencies to cease using Anthropic’s services. This directive followed Anthropic’s refusal to compromise on certain safeguards concerning military applications during contract negotiations with the government.
This revelation about the NSA’s use of Mythos Preview surfaced just days after Anthropic CEO Dario Amodei met with White House chief of staff Susie Wiles and other officials. The purpose of this meeting was reportedly to discuss Mythos. The White House later described the Friday meeting as “productive and constructive.” Yet, when reporters questioned President Trump about it, he claimed he had “no idea,” according to Reuters.
According to Axios’ sources, the NSA is among roughly 40 organizations that Anthropic granted access to Mythos Preview. One source further indicated that the model is “being used more widely within the department,” suggesting broader adoption within government circles than previously understood.
Meanwhile, Anthropic remains embroiled in a legal battle with the U.S. government. In March, the AI company filed lawsuits against the Department of Defense in two separate courts after the Trump administration designated it a “supply chain risk.” The Pentagon filed its response shortly thereafter. While one court granted Anthropic a preliminary injunction to temporarily block this designation, federal judges in the other court denied its motion to lift the label.
The situation highlights the complex interplay between advanced AI technology, national security interests, and evolving government policies. Despite a direct order from the President and ongoing legal disputes, certain government entities appear to be exploring and utilizing Anthropic’s AI capabilities, particularly its cybersecurity features. This ongoing tension underscores the challenges of regulating and deploying cutting-edge AI in sensitive national security contexts.
