Comparison
Fable 5 is back for everyone — Mythos 5 only for vetted orgs
Both were suspended on June 12, and both have returned — but to very different audiences. Fable 5, the public model, is back worldwide as of July 1 after the US lifted its export controls. Mythos 5, the less-restricted sibling, is back only for a set of vetted US 'Project Glasswing' organizations that defend critical infrastructure — not the general public.
Quick summary
- Fable 5 was the public model; Mythos 5 was a restricted, trusted-access model.
- Both were suspended June 12; both are back, but differently.
- Fable 5 is back worldwide (July 1) inside paid Claude plans; Mythos 5 is back only for vetted US orgs.
- If you're not in an official trusted-access program, Mythos 5 still isn't a route you can use — but Fable 5 is.
Before the suspension
Anthropic described Fable 5 as a public Mythos-class model, while Mythos 5 was reserved for trusted programs.
After the reversal: the two split
When the US lifted the controls on June 30, the two diverged in who got them back. Fable 5 returned worldwide on July 1 inside paid Claude plans. Mythos 5 came back earlier and separately — cleared June 26 for vetted critical-infrastructure organizations and redeploying on Amazon Bedrock and Microsoft Foundry through Anthropic's Project Glasswing program. Mythos 5 is not a public route; Fable 5 is now the model the public can actually use.
What users should know
If you are not in an official trusted-access program, treat Mythos 5 as context for understanding Fable, not as something to buy or unlock — and just use Fable 5, which is back for everyone (in-plan on Max and Team Premium, on metered usage credits for Pro).

Are Fable 5 and Mythos 5 the same?
They are related in Anthropic's launch framing, sharing the underlying model, with different access and safeguards.
