Is claude-fable-5 back yet?

Yes — Fable 5 is back. FableWatch's monitor confirmed claude-fable-5 answering on July 1, 2026 at 7:29 PM ET and alerted the watch. Per Anthropic, it returned with a new safety classifier that routes some cybersecurity-adjacent requests to Opus 4.8. The live status at the top of this page tracks it continuously — and FableWatch now watches for the next Mythos-class model.

Why was claude-fable-5 suspended?

Anthropic suspended access to claude-fable-5 on June 12, 2026, reportedly after a US Commerce Department export-control directive — described in reporting as a letter from Secretary Howard Lutnick to Anthropic CEO Dario Amodei. The specifics are attributed to news outlets and remain partly unconfirmed; FableWatch is not affiliated with Anthropic and does not have inside information.

What is FableWatch watching now?

The next Mythos-class model. Fable 5 was the first Mythos-class release, and the next one — Fable 6, or a 5.1 — is the drop worth being first to. FableWatch pings the claude-fable-5 endpoint every 60 seconds and watches Anthropic's model lineup for new Mythos-class ids; the moment a new state-of-the-art model is live, subscribers are alerted. Our guarantee still stands: if you bought a paid tier and its alert never fired within 90 days of purchase, email us and we'll refund you in full. You're paying for the window, not a gamble.

Is this affiliated with Anthropic?

No. FableWatch isn't affiliated with, endorsed by, or connected to Anthropic. We built the independent monitor that caught claude-fable-5's July 1 return the minute it happened — and now we watch for the next drop.

Is it a subscription?

No. Every paid tier is a single one-time charge — The Signal and The Swarm both. Nothing recurring, nothing to cancel.

What exactly do I get for paying?

The Signal: you're alerted first — email and push fire instantly the minute a new state-of-the-art model answers, ahead of the free list, with SMS and an automated call to your verified number the same minute. The Swarm: all of that, plus a dedicated VPS that runs a 400+ question set in parallel on the new model on your own Anthropic key, plus GitHub fix suggestions — the Swarm drafts a suggested fix as a comment on your connected repos — with every answer appearing on your dashboard as it's captured (refresh to update).

When do SMS and calls actually fire?

Email and push are instant. SMS and an automated call are live too — US carrier registration (A2P 10DLC) has cleared, so once you verify your number, texts and calls fire the same minute Fable answers. And per our guarantee, if a paid tier never reaches you we refund it in full — you're never out money for a channel that couldn't deliver.
