US government forces Anthropic to shut down its most powerful AI models over security fears - Cryptopolitan

Commerce Department ordered Anthropic to block foreign access to Claude Fable 5 and Claude Mythos 5 over national security concerns. * Anthropic disabled both models for all users, saying it could not reliably enforce access by nationality. * The shutdown came just three days after launch, after criticism over safety filters, hidden restrictions, and data retention policies. **Anthropic disabled its two top-performing AI models on Friday, June 12 following an export control order from the U.S. Department of Commerce. Commerce Secretary Howard Lutnick ordered Anthropic CEO Dario Amodei at 5:21 p.m. ET on Friday to restrict access to Claude Fable 5 and Claude Mythos 5, according to Anthropic’s statement. The directive followed a warning from an unnamed company about a technique that could bypass parts of Fable 5’s safety system, Axios reported, citing an administration official. Anthropic had released the two models only three days earlier, on June 9. Fable 5 was publicly available, while Mythos 5 was limited to selected cybersecurity partners under Project Glasswing.
