Anthropic says Trump admin has lifted export controls on Claude Fable 5 and Mythos 5

Anthropic's Claude Fable 5 and Mythos 5 AI models, which the U.S. government had restricted from being shared with foreign nationals due to national security concerns, have been cleared for release again following negotiations with the Trump administration. Fable 5 will be available globally starting Wednesday through Claude's platforms, while Mythos 5 access has been restored for some U.S. organizations with plans to expand through Anthropic's Glasswing program (a cybersecurity initiative providing selected organizations access to advanced AI models for defensive security testing).
