Original post body:

I was genuinely excited to try Fable 5.1, especially since I’m already paying for the 20x Max plan.
But after just 2 proper Fable 5.1 coding sessions, my Fable-specific usage was already at 100%, and I had burned through almost 50% of my entire weekly usage.
That’s honestly crazy for a plan this expensive.
I understand that Fable 5.1 is probably much more compute-heavy than the other models, and I really like what I’ve seen from it so far. But if two serious sessions can consume that much of the allowance, I don’t see how it’s practical as a daily coding model.
At this rate, even the 20x Max plan feels extremely restrictive if you actually want to use Fable regularly.
Anyone else on Max 20x seeing the same kind of usage? How many Fable sessions are you realistically getting per week?
Right now, I’m seriously questioning whether the 20x plan is worth it.
