The U.S. is controlling global access to the world's most powerful AI

The U.S. Commerce Department ordered Anthropic to block all foreign nationals from accessing its most advanced AI models (Claude Fable 5 and Mythos 5) under export control law, forcing a global shutdown. After Anthropic significantly weakened the models' capabilities, the department lifted restrictions—establishing a precedent for treating AI service access as a controlled export, despite uncertain legal grounding.
