Summary
Anthropic launched Claude Fable 5 (generally available) and the access-restricted Claude Mythos 5 on June 9, 2026 for long-horizon AI work, with early debate centering on safety routing and trusted-access limits. On July 1, 2026 Anthropic began restoring worldwide access to both models after the US Department of Commerce notified the company it had removed the export controls that had limited their availability.
What changed
After the June 9 launch of Claude Fable 5 and the trusted-access-only Claude Mythos 5, the US Department of Commerce removed the export controls applied to the two models, and on July 1, 2026 Anthropic began restoring global access.
Why it matters
The reversal resolves the access-restriction overhang that defined these models at launch: it restores Anthropic's high-end models to international customers and underscores how policy, not just capability, now gates which frontier AI infrastructure enterprises can deploy and where.
Evidence excerpt
Anthropic said it would begin restoring access to Claude Fable 5 and Mythos 5 from tomorrow, after the US Department of Commerce notified the company that it had removed its export controls.
