Has anyone actually enabled /usage-credits to use Fable at API pricing?

It's ridiculously expensive. At my _previous_ usage in the subscription, I estimated (with Claude) that I would spend more than 20k USD in a month.

It's insane.

I personally thought we only had Fable until tonight so now I'm blazing through tomorrow. I'm somehow still only at 22% because I was late to the game!
