The Trump administration is close to allowing Anthropic to restore access to its powerful Fable 5 model, which has been offline for 15 days because of security fears by the government.

Insiders expect the administration’s limits on Fable 5 could be lifted as soon as this coming week, a source familiar with the situation tells me.

A second source tells Axios’ Sam Sabin that conversations are expected to continue over the weekend, and Anthropic expects to restore Fable access soon.

🦾 Why it matters: For developers and even non-technical early adopters, Fable 5’s blackout was unprecedented and deeply jarring — a top-tier model, already in users’ hands, pulled offline due to government intervention, Axios’ Zachary Basu writes.

🏛️ The big picture: The progress toward liberating Fable 5 marks a thaw in a bitter four-month, bicoastal standoff between the administration and Anthropic, based in San Francisco.

In another sign of de-escalation, the Commerce Department yesterday allowed Anthropic to restore access to Mythos 5, the company’s strongest cybersecurity model, for a limited number of trusted users. Mythos 5 has guardrails to deter its use in cyberattacks or biological terror, and has never been freely available.

💻 Fable 5’s return is eagerly awaited by users, who quickly fell in love with the model’s deep thinking and quick, sophisticated coding. Developers were wowed by the leap in capability. Every new model, especially open-source ones, is being measured against Fable 5.

The Pentagon and National Security Agency still have to give Fable 5 the green light, so the outcome remains unpredictable. But other government agencies have determined Fable 5 can safely return to the wild.🔎 

Behind the scenes: I’m told that Commerce Secretary Howard Lutnick and Treasury Secretary Scott Bessent have helped defuse the fight between the administration and Anthropic.

Anthropic “has worked positively with the government,” one administration source told Axios. That’s quite a change from the furious statement by Defense Secretary Pete Hegseth designating Anthropic a “Supply-Chain Risk to National Security,” after he and Anthropic CEO Dario Amodei couldn’t agree on how the Pentagon can use Claude.

🔭 Zoom in: Anthropic had billed it as the most capable model ever released to the public. The “Vibe Check” newsletter from Every, a media and software company, called it “the best coding model in the world” before it was pulled, just three days after launch.

In early testing highlighted by Anthropic, the payments company Stripe used Fable 5 to overhaul a 50-million-line codebase in a single day — a job that would have taken engineers more than two months by hand.

When access vanished June 12, developers found automated work frozen mid-task. Companies raced to swap in rivals, including cheaper Chinese models.Share this story … Go deeper: Commerce Department greenlights limited return of Anthropic’s Mythos.
