The Trump administration has forced Anthropic to take its latest AI models, Fable 5 and Mythos 5, offline after ordering the company to cut access for all foreign nationals—a move that effectively blocked the models for everyone, including US-based users and Anthropic's own employees. The government cited "national security authorities" to justify the export control action but has not publicly explained the legal basis, marking what appears to be the first time US export rules have been used to restrict AI model access in this manner.
Why it matters: This sets a precedent for how governments can use export controls to regulate AI access and raises critical questions about the legal frameworks governing AI distribution and the practical implications for AI companies operating across borders.
