On Wednesday, Anthropic told 50,000 contractors across 56 countries to start using Claude.
On Friday, the United States government told Anthropic that no foreign national on earth was allowed to touch its two most powerful models.
Same company. Same week. Read the two announcements back to back and you are watching the global AI economy and the national security state collide in real time.
Here is what actually happened, stripped of the panic.
The models are Fable 5 and Mythos 5, the most capable systems Anthropic has ever shipped, live for three days. At 5:21 on Friday evening, Commerce Secretary Howard Lutnick sent an export control directive citing national security. It barred access by any foreign national, inside or outside the United States, including Anthropic’s own foreign-national employees. Because a company cannot reliably sort its users by citizenship in real time, the only way to comply was to switch the models off for everyone, everywhere. The most advanced public AI on earth went dark worldwide because of a clause in a letter.
The internet immediately decided this meant green-card holders, including a famous foreign-born researcher, were locked out of their own lab’s models. That part is almost certainly wrong, and the error matters. Under the same export law the directive draws on, a green-card holder is a US person, not a foreign national, and the deemed-export rule explicitly does not apply to permanent residents. The people actually swept up are visa holders. H-1Bs. The engineers on temporary status who hold up a huge share of every American AI lab.
Now hold the two announcements together and the absurdity sharpens.
The trigger, by Anthropic’s own account, was a single demonstration where the model was asked to read a codebase and fix its flaws, and it surfaced a handful of previously known, minor vulnerabilities. That is the capability. Finding bugs in code, the thing defenders do every day, the same kind of work a researcher used two weeks ago to catch a four-year-old hole in Zcash before it could be drained. Anthropic says the identical task runs on OpenAI’s GPT-5.5, which sits under no control at all. One lab’s model is pulled from the entire planet. A rival’s model, doing the same thing, stays online.
This is the contradiction the United States has not resolved and is now living inside. It wants its champion labs to win the world, so it blesses a deal to push Claude to 50,000 workers across 56 countries. It wants those same models treated as munitions, so it bars every foreign national from the strongest ones. You cannot run an export regime built for physical weapons and classified blueprints on a product used by hundreds of millions of people in every country at once. The two goals are now openly at war, and a frontier model is the battlefield.
Step back and the pattern is the one that keeps repeating. A zero-knowledge proof hid a four-year flaw. A clean audit hid a redemption gate. And an export rule written for missiles turns out to have no clean answer for who, inside a global company, is even allowed to use the software.
The safest lab in AI shipped its most powerful model, signed its biggest global deal, and got that model switched off by its own government in the same week, over a bug-finding trick a competitor runs untouched.
Anthropic calls it a misunderstanding and says it is working to restore access. As of now the models are dark, the contradiction is not, and the kill switch turned out to belong to the state.
