Anthropic's two best AI models lasted three days before the US government shut them down.
On June 12, Commerce Secretary Howard Lutnick sent Anthropic an export control letter at 5:21 p.m. Eastern ordering the company to cut off all foreign access to Fable 5 and Mythos 5. These are the same models we covered Wednesday for their self-imposed bio and cyber restrictions. By the weekend, Anthropic had pulled both offline globally rather than try to police access millions of users at a time.
The trigger wasn't Anthropic. It was Amazon. According to the Wall Street Journal, Amazon CEO Andy Jassy had been talking with US officials about a security report Anthropic shared with Amazon as part of their cloud partnership. Those conversations are what put Fable 5 on the White House's desk in the first place.
The report itself described a narrow jailbreak that let outside researchers prompt Fable 5 into helping identify software vulnerabilities. Anthropic considered the issue limited, and built the model to silently downgrade to Opus 4.8 when its safety classifiers flagged a session. That happened in fewer than 5% of cases. The administration was unmoved.
Katie Moussouris, the CEO of security firm Luta Security and one of the researchers Anthropic shared the report with, told Yahoo News the response "seems way out of line with what's actually in the research report." She pointed out that her team was finding vulnerabilities the same way normal security defenders find them every day.
None of this came out of nowhere. Back in February, Axios reported that Defense Secretary Pete Hegseth gave Dario Amodei until Friday evening to grant the military unrestricted access to Claude or face penalties. Anthropic held firm. The friction between the company's safety brand and the administration's preference for fewer guardrails has been quietly building for months, and Fable 5 gave Washington the opening it needed.
Anthropic's official response was measured but sharp. The company said it disagreed "that the finding of a narrow potential jailbreak should be cause for recalling a commercial model deployed to hundreds of millions of people," and warned that if a one-off jailbreak became the bar for action, every frontier lab's next deployment would be in jeopardy.
The international reaction has been some mix of frustrated and resigned. Anton Leicht, a fellow at the Carnegie Endowment for International Peace, told TIME the move "shows how irrelevant most other countries have become to AI policy," noting that neither foreign market access nor any country's ability to retaliate appears to have factored into the decision. UK AI Minister Kanishka Narayan said the lesson is that access to frontier AI is now a national security question, full stop.
INTO THE VALLEY
The real story isn't Fable 5 or even Anthropic. It's that a private conversation between Amazon's CEO and the White House was enough to take the most powerful AI models in the world offline within a week of launch. That's a level of discretionary power over the frontier that didn't exist a year ago, and there's no reason to expect it'll be used sparingly going forward. The other labs are watching. The next safety report any of them shares with a cloud partner is going to come with a much more careful decision about who actually sees it.
