The Pentagon has warned Anthropic, an artificial intelligence company, that it must agree to the military's terms for using its AI technology by Friday or face termination of their partnership and being designated as a supply chain risk. The Pentagon says it wants to use Anthropic's AI models for all lawful purposes but won't let the company dictate any limits on how the technology is used.

Why it matters

This standoff highlights the tensions between tech companies and the military over the use of advanced AI systems. Anthropic has policies in place to prevent its models from being used for mass surveillance or autonomous weapons, but the Pentagon is pushing to have unfettered access to the technology for its own purposes.

The details

During a meeting on Tuesday, Defense Secretary Pete Hegseth warned Anthropic CEO Dario Amodei that the military could designate the company as a supply chain risk, cancel its contract, or invoke the Defense Production Act to compel Anthropic to provide its AI technology. Pentagon spokesman Sean Parnell reiterated on Thursday that the military wants to use Anthropic's models for all lawful purposes and won't let the company dictate any limits, giving it until 5:01 PM ET on Friday to agree to the demands.

  • The Pentagon meeting with Anthropic took place on Tuesday.
