Anthropic says Pentagon's "final offer" is unacceptable

Catch up quick: The Pentagon and Anthropic are in a high-stakes feud over the limits Anthropic wants to place on the department's use of its AI model Claude: no mass surveillance or autonomous weapons.

The Pentagon this week started laying the groundwork for one consequence — blacklisting the company as a supply chain risk — by asking defense contractors including Boeing and Lockheed Martin to assess their exposure to Anthropic.
Alternatively, Hegseth threatened to invoke the Defense Production Act to compel Anthropic to provide its model without any restrictions. Such an order may be on murky legal ground.

The Pentagon's threats "are inherently contradictory: one labels us a security risk; the other labels Claude as essential to national security," Amodei said in a blog post.

"Regardless, these threats do not change our position: we cannot in good conscience accede to their request," he added.

The big picture: The Pentagon's requirement that AI models be offered for "all lawful purposes" in classified settings is not unique to Anthropic.

While Anthropic has been the only model used in classified settings to date, xAI recently signed a contract under the all lawful purposes standard for classified work.
Negotiations to bring OpenAI and Google into the classified space are accelerating. 

What's next: Amodei said the company remains committed to continuing talks.

But if the Pentagon decides to offboard Anthropic, Amodei said the company "will work to enable a smooth transition to another provider."
