How Trump officials pushed Anthropic to shut down the world’s most powerful AI models

Anthropic says it was forced to shut down access to its new Claude Fable 5 and Claude Mythos 5 AI models after the Trump administration issued a broad warning against use of the models by foreign nationals. The warning, from the Commerce Department, would have banned even many of Anthropic’s own employees from using or working on the models. That dramatic result came after a multiday back-and-forth involving numerous administration officials and input from tech industry leaders.
