Read the live strip, not a stale claim
Availability for a model under an active government directive changes faster than any static page can keep up with, so the verdict for Claude Fable 5 is rendered from live data in the status strip above this paragraph. Treat that as the answer, with an honest "as of" timestamp, and confirm it against the canonical live status.
How we got here
Fable 5 — the public, safeguarded edition of the June 2026 Mythos-class release — shipped on June 9 across the Claude API and major clouds. Three days later, on June 12, a US export-control directive suspended access to Fable 5 and Mythos 5 alike. Anthropic has said it intends to restore Fable 5 to its subscription plans once capacity and clearance allow, but no restoration date is confirmed.
What to do right now
If the live strip shows access is paused, your practical fallback is Claude Opus 4.8. When the directive lifts, the status page will reflect it first.
Frequently asked questions
Is Fable 5 the same model as Mythos 5?
Yes — they share the same underlying model. The difference is safeguards: Fable 5 ships safety classifiers that reroute a small share of flagged requests to Opus 4.8, while Mythos 5 runs with those classifiers lifted and is Glasswing-only.
Why might Fable 5 show as unavailable?
Because of a US export-control directive issued June 12, 2026 that suspended access. See why is Mythos restricted for the policy background.
Where is the authoritative answer?
