At 5:21pm Eastern on Friday 12 June, Commerce Secretary Howard Lutnick sent Anthropic chief executive Dario Amodei a directive barring every foreign national, inside or outside the United States, from accessing Claude Fable 5 and Claude Mythos 5 1. The order reached Anthropic's own foreign-national staff. To comply, the company disabled both models for every customer worldwide, three days after Fable 5 went on sale.
Anthropic is the San Francisco AI lab behind the Claude family of models; Commerce is the US federal department that polices what technology may leave American hands. Lutnick reached them through the deemed-export doctrine: under US law, granting a foreign national access to controlled technology on American soil counts as an export to that person's home country 2. A live consumer model cannot check the nationality of every user mid-conversation, so the only way Anthropic could keep foreign nationals out was to keep everyone out. The controlled item, in effect, became the act of using the model rather than possessing it, and no commercial AI product is built to gate inference by passport in real time.
The capability did not change on Friday. This desk has tracked the Mythos arc since April, when the Treasury and the Federal Reserve summoned five Wall Street bank chiefs over the withheld Mythos Preview, the model Anthropic distributed to twelve partners under Project Glasswing, that the UK AI Security Institute clocked at a 32-step autonomous attack chain, and that Anthropic then reframed in a 244-page Alignment Risk Update abandoning its own capability thresholds. By 1 May, OpenAI's rival GPT-5.5 had cleared the identical 32-step chain , and it remains on sale. The trigger, per Axios, was an unnamed rival claiming to have jailbroken Mythos 5 by asking it to read a codebase and fix the flaws it found; the administration first sought a launch pause, Anthropic refused, and the letter followed 3.
The campaign-money symmetry sharpens the irony. Anthropic backed the pro-regulation Public First campaign while the OpenAI camp funded the anti-regulation Leading the Future PAC . The lab that asked to be regulated is the one Washington reached first, while the untouched competitor is the one whose founders paid to weaken the rules. Restoration terms, whenever they come, will set the first precedent for how a deployed consumer model re-enters a market after a national-security recall.
