On June 12, the Commerce Department ordered Anthropic to immediately cut off foreign-national access to its top-tier model Claude Fable 5 and enterprise-only Mythos 5. With no real-time way to verify nationality, Anthropic disabled both models for every user worldwide. A week later, the models are still offline, and as negotiations over the terms of restoring them continue, President Trump weighed in publicly for the first time.
In a June 19 Axios interview, Trump said "we didn't like what they were doing," confirming the administration had viewed Anthropic as a national-security concern for some time. He credited a shift in tone to direct engagement with leadership: "He made a speech and responded very responsibly, I thought," referring to CEO Dario Amodei. Still, Trump left the door open to further action, saying "I have the power to use a lot of things."
The same day, reporting indicated the actual trigger wasn't the jailbreak concern the administration cited publicly. US officials reportedly took issue with Anthropic sharing its unreleased flagship model, Mythos, with SK Telecom, the South Korean carrier officials allege has ties to China. Separately, Amazon CEO Andy Jassy raised concerns directly to Treasury Secretary Scott Bessent that Fable 5's safety guardrails could be circumvented. Anthropic maintains it coordinated the Mythos rollout with the government in advance, has worked with SK Telecom for years without incident, and revoked the carrier's access immediately once the White House flagged it.
- Models offline: 8+ days and counting since June 12
- Anthropic's response time to the directive: disabled Fable 5 within 90 minutes
- Unaffected models: Opus 4.8, Sonnet 4.6, Haiku and the rest of the existing lineup remain available
- Official government statement: a single X post from White House tech adviser David Sacks remains the only on-record explanation
What makes this episode notable is how sharply it cuts against the administration's stated AI policy this year. The White House has spent 2026 rolling back Biden-era AI guardrails and stood up a federal task force to challenge state-level AI laws, arguing that regulation hands the lead to China. Just last month, it created a voluntary early-testing program for frontier labs with an explicit carve-out promising it would never become a mandatory licensing regime. The Fable 5/Mythos 5 shutdown produced functionally the same outcome as that licensing regime—just without the rules, timeline, or appeal process an actual regulatory framework would include.
| Date | Event |
|---|---|
| June 9 | Claude Fable 5 / Mythos 5 launch |
| June 12 | Commerce Dept. export-control directive; global shutdown |
| June 13–18 | Private negotiations, no public explanation |
| June 19 | Trump's first public comments: tensions "eased" |
| June 19 | SK Telecom / Amazon trigger reporting surfaces |
- Trump publicly confirmed tensions have eased, but the models remain offline more than a week after the shutdown
- The publicly cited reason (jailbreak risk) appears to differ from the actual trigger: Mythos access shared with SK Telecom, plus concerns Amazon's CEO raised directly to Treasury
- An administration that built its 2026 platform on deregulation effectively created an ad hoc mandatory-licensing outcome it had explicitly promised not to create
- No timeline or specific conditions for restoring the models have been disclosed
The longer this drags on, the worse it looks for both sides. Anthropic is keeping its two most capable models shelved for over a week while competitors capture market share, and the White House has invited criticism for intervening without clear rules. If restoration terms aren't settled this week, expect other frontier labs to start treating informal pre-launch coordination with regulators as a de facto requirement.
