With the Mythos debacle, Anthropic gets its first taste of the Trump admin’s new AI regulation regime.

On today’s episode of Decoder, my guest is Hayden Field, senior AI reporter for The Verge. Often when Hayden comes on the show, it’s because something has gone wrong in the world of AI. Last weekend, that something was a pretty intense mix of Anthropic, the Trump administration, and Anthropic’s new AI model, Fable 5.

On Friday, not even a week since Anthropic released Fable to the public, the US government said it was imposing export controls on the new model, as well as the underlying Mythos model that Fable is based on. Those controls restricted foreign nationals, even those working for Anthropic in the United States, from accessing these models. Anthropic then took Fable and Mythos offline for everyone, because the company said it was worried it would not be able to restrict access and reasonably comply with the order otherwise.

As you might imagine, this is all a giant mess. Hayden actually just published a fantastic play-by-play on The Verge about how this all went down last Friday and the scramble through the weekend from both sides to figure out what exactly happened and how it might get resolved. So I wanted her to come on and just walk me through the timeline and what it all means.

The situation is ongoing. As of Tuesday when we’re recording this episode, Fable is still offline — in fact, if you boot up Claude, it tells you right above the chatbox window that “Fable 5 is currently unavailable.” Yet as you’ll hear Hayden explain, whether Fable comes back online this week or not, the ripple effects of the government’s feud with Anthropic have far-reaching consequences for the tech industry and the US’s AI regulatory regime.
