Marks the end of the 18-day government suspension of Anthropic's top models.
Summary
Anthropic said it had been notified that the Department of Commerce lifted export controls on Fable 5 and Mythos 5, and that restoration would start the next day. A few hours later it posted that Fable 5 would be globally available again, redeployed with new classifiers that block more cybersecurity tasks, with some routine coding tasks possibly affected at first (x.com/AnthropicAI/status/2072163884430229756, 2026-07-01T03:42Z UTC). Details are in the 'Redeploying Claude Fable 5' post (anthropic.com/news/redeploying-fable-5, June 30). Verified via syndication: 2026-06-30T23:52:59Z.
