Two gates, not one
Even setting the suspension aside, Mythos 5 was never available to the general public. It is the edition of the June 2026 model with safety classifiers lifted, and Anthropic distributes it exclusively through Project Glasswing to a small set of vetted organisations. So "available" here has always meant "available to approved Glasswing participants" — and on top of that, the live verdict above reflects whether the current export-control suspension is in force.
What the live strip tells you
Read the status strip at the top of this page for the as-of answer; it renders from Anthropic's status feed. The June 12 directive suspended access to both June editions, so unless and until that lifts, even Glasswing access is constrained. The canonical mirror is the live status page.
Frequently asked questions
Can I sign up for Mythos 5 directly?
No. It is Glasswing-only — see Project Glasswing access. There has never been a self-serve path to the classifiers-lifted edition.
How is Mythos 5 different from Fable 5?
Same underlying model; Mythos 5 runs with classifiers lifted, while Fable 5 ships them on. Full comparison: Fable 5 vs Mythos 5.
Is the suspension specific to Mythos 5?
No — the June 12 directive covers both Mythos 5 and Fable 5. See mythos export control.
