⚡ Quick Fix — “Fable 5 Currently Unavailable” in Claude
- This is not a device or account bug — Claude Fable 5 was suspended server-side in June 2026.
- Open the model picker and switch to Claude Opus 4.8 (or Sonnet 4.6 / Haiku 4.5) to keep working.
- Check status.claude.com and Anthropic’s announcement for the latest availability.
If Claude shows “Fable 5 is temporarily unavailable” — or Claude Code returns a 404 saying “Claude Fable 5 is not available. Please use Opus 4.8” — nothing is wrong on your end. In mid-June 2026 Anthropic suspended access to Claude Fable 5 and Claude Mythos 5 following a U.S. government directive, so the model simply cannot be selected right now.

Why Is Fable 5 Currently Unavailable?
Claude Fable 5 was the first publicly available model in Anthropic’s new Mythos-class tier. According to Anthropic and multiple news reports, the U.S. Commerce Department issued a directive to block access to Fable 5 and Mythos 5 for foreign nationals. Anthropic said complying meant disabling the models entirely for all users, not just some.
As a result, on 12–13 June 2026 the Fable 5 option was pulled across Claude.ai, Claude Code and partner platforms. The landing page reported that Fable 5 was temporarily unavailable, and API/CLI calls to claude-fable-5 began returning a “not available” error pointing users to Opus 4.8.

Key Points (Important Points)
- Claude Fable 5 and Mythos 5 were suspended, not deprecated or broken.
- The suspension followed a U.S. government export-control directive.
- It affects all users and surfaces (Claude.ai, Claude Code, partner platforms).
- Other models remain available — Claude Opus 4.8, Sonnet 4.6 and Haiku 4.5.
- There is no client-side fix; updating or reinstalling will not restore Fable 5.
What to Do When Fable 5 Is Unavailable
1Confirm it’s the suspension, not a bug — If you see ‘temporarily unavailable’ or a 404 telling you to use Opus 4.8, this is the server-side suspension — not your account.
2Switch to Claude Opus 4.8 — Open the model picker and select Opus 4.8 (or Sonnet 4.6 / Haiku 4.5). These remain fully available.
3Update Claude Code (if the picker looks wrong) — Older Claude Code builds may not show models correctly; update to the latest version so Opus 4.8 appears cleanly.
4Don’t hard-code claude-fable-5 — In API/CLI workflows, point requests to an available model ID until Anthropic restores Fable 5.
5Watch the official status page — Check status.claude.com and Anthropic’s announcement at anthropic.com/news/fable-mythos-access for any change in availability.

Frequently Asked Questions (FAQ)
Why is Fable 5 currently unavailable in Claude?
Anthropic suspended Claude Fable 5 (and Mythos 5) in mid-June 2026 after a U.S. Commerce Department directive to restrict access for foreign nationals. Anthropic said meeting that requirement meant disabling the models for everyone.
Is ‘Fable 5 unavailable’ a bug I can fix?
No. It is a server-side suspension, not a fault on your device or account. Reinstalling, clearing cache or changing settings will not bring Fable 5 back.
What model should I use instead of Fable 5?
Switch to Claude Opus 4.8 for complex work, or Sonnet 4.6 / Haiku 4.5 for lighter tasks. All three remained available during the Fable 5 suspension.
Will Claude Fable 5 come back?
Availability depends on Anthropic and the regulatory situation. Watch status.claude.com and Anthropic’s official announcement page for updates rather than relying on third-party claims.
