Anthropic chief executive Dario Amodei has said the company has "no choice" but to challenge in court the Pentagon's formal designation of the artificial intelligence firm as a risk to US national security.

Anthropic PBC vowed to legally contest a Pentagon decision to declare the company a threat to the US supply chain under an authority normally reserved for foreign adversaries, escalating a showdown with the Trump administration over artificial intelligence safeguards.

A top Pentagon official says a fight with Anthropic centered on how the military could someday use artificial intelligence in autonomous weapons. Defense Undersecretary Emil Michael told

Anthropic CEO Dario Amodei is reportedly back at the negotiating table with the U.S. Department of Defense after the breakdown of talks on Friday.

After refusing the Pentagon’s demand for unrestricted access to its AI, Anthropic nearly faced a “supply chain risk” designation that could have cut the company off from defense contracts.

Anthropic’s moral stand on U.S. military use of artificial intelligence is reshaping the competition between leading AI companies but also exposing a growing awareness that maybe chatbots just aren’t capable enough for acts of war.

In tense negotiations, Anthropic sought specific restrictions on the use of its AI technology by the Department of Defense, which the agency did not agree to.

The Pentagon's top technology official told CBS News the military has offered compromises to Anthropic, amid a feud over whether its powerful AI technology will be restricted — but Anthropic called the offer inadequate.
