TL;DR: Anthropic has suspended user access to Claude Fable 5 following a U.S. government export control directive.
Summary: Anthropic temporarily suspended access to Claude Fable 5 and Mythos 5 after a U.S. government export control directive targeting foreign nationals, including its own non-U.S. employees. During this suspension, new sessions will default to Opus 4.8 or the user's selected model, while active Fable 5 sessions will result in errors. Anthropic believes the directive is a misunderstanding and is actively working with authorities to restore access.
Why it matters: This highlights how geopolitical regulatory compliance can abruptly disrupt access to cutting-edge models. AI builders should design robust fallback options into their multi-model applications to handle sudden API suspensions.
