Codex usage cycles not aligned with ChatGPT billing cycles - Plus quota immediately gone on downgrade from Pro

What version of Codex is running?

codex-cli 0.77.0

What subscription do you have?

Pro subscription downgrading to Plus

Which model were you using?

gpt-5.2-codex

What platform is your computer?

Darwin 25.3.0 arm64 arm

What issue are you seeing?

When downgrading from Pro to Plus subscription, the Plus quota is immediately exhausted and no longer available.

This occurs because Codex usage cycles are not aligned with ChatGPT billing cycles. The misalignment causes unexpected quota depletion when users downgrade their subscription tier.

What steps can reproduce the bug?

Downgrade from Pro to Plus. Continue using Pro until the last minute. When the billing cycle renews and Codex requests start to count towards the Plus plan, it counts the weekly requests used as part of the Pro plan.

What is the expected behavior?

When downgrading from Pro to Plus, the Plus subscription quota should be reset when the billing cycle renews. Users should not experience immediate quota exhaustion upon downgrade.

None of those are duplicates, since they don't address the context of a downgrade; they relate to other fluctuations in usage calculations.

Was this ever resolved? This just happened to me. I downgraded from PRO to PLUS and when it took effect, my weekly usage limit instantly became 0%.

The chatgpt help assistant said:

Yes, that's correct—when you switch from Pro to Plus, any Codex usage you made during the current week (while on Pro) is applied to the new, lower Plus weekly limit as soon as your plan changes. This means if you already used more than the Plus weekly allotment before switching, your Plus usage for the rest of that week will show as 0% left, and any further usage will start using your purchased credits. The usage window resets on the regular Plus schedule.

Based on official documentation, when you switch plans (for example, from Pro to Plus), your usage for the current week is applied to the new (lower) weekly limit of the Plus plan immediately. This means if you already used more than the Plus allowance while on Pro during that week, you will see 0% remaining right after the switch, and any further usage begins consuming paid credits.

It doesn't seem reasonable.

I paid for a month of PRO and used it. Then I paid for a month of PLUS, but my week starts with 0%? That's like downgrading a gym membership, but you're not allowed to re-enter the gym until the next week.

The person assigned to my case basically reiterated what the help assistant said. So apparently this situation is intended.

Yeah, that is funny. Gotta remember to purchase to brand new account next time, great!
