Anthropic Races to Washington to Lift Its Model Ban

The fight between Anthropic and the Trump administration has moved from order to negotiation. After a federal export-control order forced the company to switch off its two newest models for everyone, Anthropic sent senior engineers to Washington this week to try to undo it.

The order landed on Friday, June 12, when the administration invoked national-security export-control authority to bar foreign governments, companies and individuals from using Claude Fable 5 and Mythos 5. We reported the shutdown when it happened. Because the restriction reached any foreign national, including some of Anthropic's own foreign-born staff, and the company could not reliably wall those users off in real time, it took the blunt path and disabled both models worldwide rather than risk breaking the rule.

The meeting

On Monday, June 15, senior Anthropic technical staff met administration officials in Washington in pursuit of a deal, according to reporting from the Wall Street Journal and others. No resolution came out of the room. Both sides said they wanted one quickly, which is the kind of thing parties say when they have not got one.

The reported trigger is unsettling in its own right. Fortune reported that a warning from Amazon helped prompt the shutdown, after suspicions that a group linked to China had gained access to Mythos 5. An export-control order is a heavy instrument, and the speed with which it was used says something about how seriously Washington now treats access to frontier models.

A longer quarrel

This is not a one-off. The episode caps a months-long standoff between the company and the administration. Earlier this year the government designated Anthropic a supply-chain risk for Pentagon contractors after the company declined contract terms that would have allowed its models to be used for "all lawful purposes." Axios, citing people close to the talks, captured the mood in two words: "They screwed us."

The timing is awkward for Anthropic, which is preparing to seek public investors and cannot easily explain to them why its flagship products can be switched off by government order over a weekend. The wider lesson is harder to shake. Even a US lab, building what it calls safe models on home soil, now operates at the pleasure of its own government.

The same week, Anthropic was making a very different kind of argument about control, proposing a coordinated global pause on the most advanced development. For now the more immediate question is narrower: whether its engineers can talk Fable 5 and Mythos 5 back into existence.
