🧠 Redeploying Fable 5

Update
Claude Fable 5 and Mythos 5 redeployed

1 Jul 2026

Access to Claude Fable 5 and Mythos 5 is now restored.

On Friday, June 12, the US government applied export controls to our newest models, Claude Fable 5 and Claude Mythos 5. This required us to restrict access to foreign nationals, whether inside or outside the United States. Because the order took effect immediately and we had no reliable way to verify nationality in real-time, we suspended access to both models for all users.

As of today, June 30, the export controls on Fable 5 and Mythos 5 have been lifted.
