This builds upon deals with OpenAI and xAI, which have already reached agreements with the Pentagon for the “lawful” use of their AI systems. A report from The Information suggests Google has struck a similar agreement. As noted by The Wall Street Journal, Microsoft and Amazon already have “deep relationships with the Pentagon,” while contracts with Nvidia and Reflection are new.

And while Anthropic had a $200 million deal to handle classified materials for the Pentagon, it refused to loosen “red lines” around mass domestic surveillance and fully autonomous weapons for the agency, leading to a dispute that banned the AI startup’s products from the federal government. Anthropic sued the federal government in response and won a temporary injunction.

Emil Michael, the Defense Department’s chief technology officer, told CNBC on Friday that Anthropic is still a supply chain risk, but called its powerful security model, Mythos, a “separate national security moment,” adding that “we have to make sure that our networks are hardened up, because that model has capabilities that are particular to finding cyber vulnerabilities and patching them.”

In its announcement, the Pentagon says the agreements with the seven AI companies will allow for the “lawful operational use” of their systems, “establishing the United States military as an AI-first fighting force.”
