Hi,
I've been using Codex since day one, but I now feel very disappointed.
I burned through my 5-hour quota in less than 10 minutes this morning using 5.5 High in plan mode and 5.5 Low for implementation.
About a month ago, it felt almost unlimited, but now I’m getting a Claude-like experience!
Is there a bug causing this?
Thanks

What steps can reproduce the bug?

Just use Codex

What is the expected behavior?

Yep, had to switch back to 5.4, which is working as expected with much lower drain on credits, if the usage limits for 5.5 is working as intended, then it's barely useable at all on a business plan, for anything but two simple prompts for minor code changes every 5h.

But "luckily" 5.4 is pretty decent even compared to 5.5 for the tasks we use it for here at work, didn't notice any real code quality benefit with 5.5 for our codebase over 5.4

Had exactly the same experience today. One prompt with 5.5 xHigh running for 10-20 minutes and quota was 0. That's just useless.
