US Move to Limit Anthropic AI Models Signals New Phase in Technology Controls

San Francisco, 13 June 2026 – Anthropic has disabled access to its advanced Fable 5 and Mythos 5 artificial-intelligence models after the United States government issued an export-control directive restricting foreign access, marking a major escalation in how Washington is seeking to regulate frontier AI.

The directive suspends access to the models for foreign users, reflecting growing national-security concerns over the potential misuse of advanced AI systems. The move suggests that US technology controls are widening beyond chips, servers and hardware infrastructure into the AI models themselves.
