On June 13, 2026, the US government ordered Anthropic to disable its advanced AI models, Fable 5 and Mythos 5, for all users globally. This action was taken by the US Commerce Department under a new executive order, invoking "deemed export" rules that treat advanced AI as dual-use munitions. The order aimed to prevent foreign nationals from accessing the models, but due to Anthropic's inability to distinguish users in real-time, a complete shutdown was mandated. This event signals the end of unrestricted AI access and the beginning of geopolitical fragmentation in AI development and availability. AI
