Redeploying Claude Fable 5
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.
TL;DR
- US government applied export controls to Claude Fable 5 and Claude Mythos 5 on June 12.
- Controls required restriction of access to foreign nationals.
- Access to both models was suspended for all users due to immediate effect and verification challenges.
