Until this week, Anthropic was the only AI company cleared to deploy its models on classified networks. Elon Musk's xAI is now the second.

A public showdown between the Trump administration and Anthropic is hitting an impasse as military officials demand the artificial intelligence company bend its ethical policies by Friday or risk

Anthropic CEO Dario Amodei said on Thursday the company "cannot in good conscience accede" to the military's terms over the use of Claude.

Anthropic issued a statement earlier today stating that the company will not allow its AI platform to be used for mass domestic surveillance and fully autonomous weaponry by the United States government. Employees from both Google and OpenAI have joined in this call for AI red lines.

Chief Pentagon Spokesman Sean Parnell said Thursday that the DoD has "no interest" in using Anthropic's models for fully autonomous weapons or to conduct mass surveillance of Americans, which he noted is illegal. He emphasized that the agency wants the company to agree to allow its models to be used for "all lawful purposes."

As well as designating Anthropic as a supply chain risk, the government could also cancel its contract or invoke a Cold War-era law called the Defense Production Act to give the military more sweeping authority to use its products, even if the company doesn’t approve.

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.

The US government is putting pressure on AI company Anthropic over military use of its technology. Defense Secretary Pete Hegseth has given a deadline for the company to allow its AI to be used in legal defense work.
