"For subscription plans, we’d rather give access sooner than later, so we’re rolling out more conservatively, in stages:

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."

Now it's a "promotion" that we get to access to Fable for 9 days instead of the original 14 days announced. They are generously throwing in a special halving of the usage "at no extra cost", and freely admit that their classifier is broken and will need to be improved.

Well thanks!
