Anthropic disables Fable 5, Mythos 5 models per U.S. export control directive
Anthropic has shut down access to two frontier AI models (Fable 5 and Mythos 5) in response to a U.S. government export control order, marking the first major frontier lab capitulation to AI model restrictions.
WHY IT MATTERS
Signals that frontier AI labs now face real regulatory teeth on model distribution; expect similar pressure on OpenAI and Google to restrict access in non-allied jurisdictions.
