Quoting Anthropic's announcement of Fable 5 (https://www.anthropic.com/news/claude-fable-5-mythos-5):

• From today through June 22, Fable 5 is included on Pro, Max, Team, and seat-based Enterprise plans at no extra cost.

• On June 23, we’ll remove Fable 5 from those plans. Using it after that will require usage credits. If capacity allows, we’ll extend the included window.

• After this point—when sufficient capacity allows us to do so—we aim to restore Fable 5 as a standard part of subscription plans. We intend to do this as quickly as we can.

This market concerns paid individual plans (currently: Pro, Max 5x, Max 20x). By "coverage" of a model by a plan, we mean that the model can be used as part of that plan's included usage, potentially at a usage multiplier, but not requiring usage credits.

If individual plan coverage for Fable 5 does not stop on or shortly after June 23, this market resolves N/A. If coverage does stop, then the market resolves to the first date on which Fable 5 (or a successor Fable-class model) returns to individual plan coverage.
