Anthropic CEO Dario Amodei will meet with Defense Secretary Pete Hegseth at the Pentagon on Tuesday morning to discuss how the military will use the startup’s artificial intelligence models, CNBC confirmed.

Negotiations between Anthropic and the Department of Defense have hit a snag in recent weeks as the two organizations have clashed over the terms of use for Anthropic’s technology.

Anthropic wants assurance that its models will not be used for autonomous weapons or to spy on Americans. The DoD has made clear it wants to use Anthropic’s models “for all lawful use cases,” without limitation.

As of February, Anthropic is the only AI company that has deployed its models on the DoD’s classified networks and provided customized models to national security customers. The company was awarded a $200 million contract with the DoD last year.

Axios was first to report the upcoming meeting between Amodei and Hegseth.
