Note that Max is the $100/$200 per month plan; In addition to the obvious incentive to upsell, I suspect attempting to use Fable on the $20 per month plan would wreck your quota.
On a related note, Codex just reset their weekly quota, again.
Not true. I have used Fable for all my planning work in a reasonably large but well organsied codebase and I rarely hit a session limit. I would use all of the Fable specific usage if I accidently let it do the full implementation of the plan. Pro was perfect for me. I would then used GPT-5 / Composer 2.5 for implementation followed by a Fable check over. I will definetly see if the API usage in Cursor is enough to cover my Fable needs before upgrading.
Now if they could just extend the 50% weekly limit increase promotion which will otherwise expire on July 19th at 11:59PM Pacific, they might actually remain competitive.
