When will Anthropic release the next Mythos-Class model?

Resolves Yes if Anthropic releases a model under Anthropic's Mythos tier — including models branded "Mythos" or "Fable" - excluding Claude Fable 5 (released June 9, 2026) before Aug 1, 2026, then the market resolves to Yes.

Release must be to the public, outside of a closed beta, though limiting it to a high-cost subscription tier is acceptable.
