Anthropic suspends access to Claude Fable 5
A U.S. export-control directive barred foreign nationals from Fable 5 and Mythos 5, leading Anthropic to suspend access for every customer because it could not verify nationality in real time.
What happened
Event details
Anthropic said the directive applied to foreign nationals inside and outside the United States, including its own foreign-national employees. Because the order took effect immediately and did not include specific details of the cited national-security concern, the company disabled both models for all users while continuing to dispute the technical basis for the action and working to restore access.
Assessment
Why it matters
A nationality-based restriction became a global shutdown because real-time nationality verification was unavailable, showing how export controls can directly reshape access to newly released frontier models.

Access notes
Access was suspended for all users on June 12, 2026. The export controls were lifted on June 30 and Fable 5 returned globally on July 1.
