Anthropic Disables Claude Fable 5 for All Customers After US Order

On June 12, 2026, Anthropic immediately disabled access to its latest top-tier models Claude Fable 5 and Claude Mythos 5 for all customers, acting on an export-control directive from US national security authorities. The directive calls for halting access to these models by foreign residents inside and outside the US, including Anthropic's foreign employees, while other Claude models are unaffected. In its official statement, the company said the action is "based on a misunderstanding" and that it will restore access "as quickly as possible."
