US bans Anthropic's Fable 5, Mythos 5 access for foreign nationals
On June 12, 2026, the U.S. government told Anthropic to stop access to its advanced AI models, Fable 5 and Mythos 5, for all foreign nationals. Because Anthropic could not easily check users' nationalities, the company took both models offline for everyone around the world. The order was based on export rules that say sharing certain technology with foreign people, even inside the U.S., may need special permission. Anthropic disagreed with the order and said it might hurt new AI model releases. Experts suggest this episode highlights gaps in current laws and may lead to clearer rules in the future.
