US directive pulls Fable 5 offline three days after launch

What happened. On 12 June 2026 Anthropic received a US export-control directive barring access to Fable 5 and the restricted Mythos 5 by any foreign national. Because that scope reaches foreign nationals everywhere — including Anthropic's own non-US staff — the only way to comply was to disable both models for all users. Every other Anthropic model still works.

What's disputed (developing). Anthropic says it received only verbal notice of a 'potential narrow, non-universal jailbreak,' saw a demo that surfaced a few previously-known minor bugs, and disagrees that any of it justifies a recall. The directive reportedly came via a letter from Commerce Secretary Howard Lutnick to CEO Dario Amodei (per WSJ/Bloomberg). The government's detailed rationale has not been published.

The kicker. Anthropic's rebuttal points at OpenAI's GPT-5.5, arguing rivals share the same underlying capability — and notes it is reportedly weeks from a major IPO. So far, only Anthropic's models are dark.
