When will Mythos be unsuspended?

Availability & status informational Last reviewed Updated
Mythos & Fable: Suspended

Access is currently suspended: “We’ve suspended access to Claude Mythos 5 and Claude Fable 5.” The incident remains monitoring, started 2026-06-13.

Derived from live data (Anthropic Statuspage) as of . Canonical verdict: anthropicmythos.ai/status ↗.

No date has been promised

It would be misleading to put a calendar date on this, so we won't. As of the latest data, neither Anthropic nor the directive behind the suspension has published a restoration date. What Anthropic has stated is an intent: to restore Fable 5 to its subscription plans when capacity and clearance allow. That is a direction of travel, not a deadline.

What restoration likely depends on

Two things gate a return. First, clearance — the export-control directive that triggered the suspension would need to be lifted or narrowed. Second, capacity — Anthropic has framed re-enabling subscription access around available capacity. Mythos 5, the Glasswing-only edition, follows its own access path.

How to track it

The live status strip above is the fastest honest read, since it mirrors Anthropic's status incident. When the situation changes, the canonical status page will reflect it before any explainer can be rewritten — so watch that, with an "as of" eye.
