"Mythos" is a family, so "available" has nuance
Claude Mythos is shorthand for Anthropic's Mythos-class tier, the level above Opus. It spans the April 2026 Mythos Preview, the Glasswing-only Mythos 5, and the public Fable 5. None of these has ever been open self-serve, so the live status strip above is the right place to read the current verdict.
The access history in brief
The Preview reached roughly 50 vetted organisations through Project Glasswing. The June 9 release pushed Fable 5 to the public and kept Mythos 5 inside Glasswing. Then a June 12 US export-control directive suspended access to both June editions, and that suspension remains active.
Where to confirm
Because the situation is governed by a live directive, treat the strip above — and the canonical live status — as authoritative, with an honest "as of" reading.
