U.S. Orders Anthropic to Suspend Fable 5 and Mythos 5 Access for Foreign Nationals

Anthropic announced on Friday it will suspend access to its advanced AI models, Claude Fable 5 and Mythos 5, for foreign nationals following a U.S. government order. The order, received at 5:21 p.m. ET, cited national security concerns as the reason for restricting access for individuals who are not U.S. citizens or permanent residents, regardless of their location. Anthropic stated that to comply with the directive, it would "abruptly disable" these models for all users. The company indicated it is working to implement the necessary technical changes to enforce this restriction. This action comes amid growing international scrutiny and regulatory efforts concerning the development and deployment of powerful AI technologies.
