Anthropic Restores Access to Claude Fable 5 and Claude Mythos 5 Following U.S. Export Rule Changes

Anthropic has announced that access to Claude Fable 5 and Claude Mythos 5 has been restored after recent changes to U.S. export restrictions. Eligible users who temporarily lost access will gradually regain availability to both models. Claude Fable 5 is Anthropic's latest high-performance AI model designed for businesses and general users, offering advanced reasoning, coding, long-context understanding, and agent capabilities. Claude Mythos 5 is built on the same foundation but is intended for research organizations and government agencies, with fewer safety restrictions for specialized use cases. The announcement highlights how government policy and export regulations continue to influence the global availability of cutting-edge AI models, in addition to their technical capabilities.
