At the time a GPT subscription didn't include Pro usage in the rolling limits. It was billed at API rates. Does it now?
If anyone wants to fund the other five cases (~$125), I'll run them. I find that an unrealistic cost, though...simply not useful data. I'm certainly not going to spend $23 per file to audit a project with hundreds or thousands of files. I don't know anyone who would.
Also note that it was $100 cap per model, and the next most expensive model was GPT 5.5 at a 20th the price per case, about ten bucks for the whole batch.
I have ~100$/mo sub and I have Pro in chat app and Extra High in Codex for GPT-5.5
I think on sub tokens might be 100 times cheaper.
The quota is also generous in my opinion. I can vibecode a lot most days of the week and not run out.
