Anthropic has once again found itself in the Trump administration's crosshairs over an inability to communicate effectively, sources tell Axios.

Why it matters: Governing the world's most consequential technology is coming down to speaking President Trump's language.

Catch up quick: On Thursday, Amazon CEO Andy Jassy called Treasury Secretary Scott Bessent expressing concerns that Anthropic's most powerful models, Mythos and Fable, could be jailbroken.

Behind the scenes: "Anthropic has not done a great job at trying to speak to the administration and appreciate the ideological differences," one source familiar with the administration's thinking said.

The administration first threatened Anthropic with export controls a couple of weeks ago after learning that its cutting-edge Mythos model was made available to an entity in a foreign country with direct ties to the Chinese Communist Party, according to the White House.

Even before this breakdown, a previous fight between Anthropic and the Pentagon also came down in some ways to just not liking the person on the other side of the negotiating table.

The big picture: Anthropic has been the loudest of the frontier AI labs on safety concerns, calling for strong regulation and spooking the Trump administration and the public with their own model's cyber capabilities.

What's next: "The immediate crisis was averted but longterm we have a problem," an administration official said.

The bottom line: One option is to make sure Anthropic's models can't be jailbroken — though perfect jailbreak resistance may be impossible.
