Woofun AI reports that Anthropic will reopen Claude Fable 5 to global users starting July 1 across Claude Platform, Claude.ai, Claude Code, and Claude Cowork. Pro, Max, Team, and certain Enterprise plan users face a 50% weekly usage cap until July 7, after which access shifts to usage quotas. AWS, Google Cloud, and Microsoft Foundry access restoration is imminent.

Regarding Claude Mythos 5, Anthropic confirmed partial access restoration for specific US institutions following June 26 government approval, with plans to expand under the Glasswing program. Both models, released June 9, share an underlying architecture; Fable 5 prioritizes security for general use, while Mythos 5 serves defensive cybersecurity for trusted partners. Anthropic also deployed a new security classifier blocking over 99% of bypass attempts, acknowledging potential false positives in routine coding tasks.
