Cannot revert to original plan after one-month hackathon Pro 5x benefit expires

What version of the Codex App are you using (From “About Codex” dialog)?

26.707.72221 (Codex desktop / ChatGPT app, macOS arm64)

Codex CLI: 0.144.4

What subscription do you have?

My account was moved to a one-month Pro 5x / Pro X5 benefit during the Paris hackathon / Codex Build Week flow because the normal credit redemption path did not work (see related issues below).

That one-month benefit has now ended.

I do not want to:

• upgrade to Go / Plus / Pro,
• buy credits,
• or add auto top-up.

I only want to return to my original pre-hackathon plan and regain a normal, consistent account state.

Right now the UI is inconsistent:

• the pricing page at https://chatgpt.com/#pricing shows plan options (Go / Plus / Pro),
• repeated attempts to change plan show: There was a problem updating your subscription (multiple stacked error toasts),
• Codex usage is blocked with usage-limit messaging (prolite_rate_limit_reached / usage_limit in local logs).

What platform is your computer?

Darwin 25.5.0 arm64 arm

OS language: en-FR

What issue are you seeing?

After my one-month hackathon Pro 5x benefit expired, I am stuck in a broken billing/subscription state and cannot return to my original plan.

User-visible symptoms

• ChatGPT pricing page shows repeated orange banners: There was a problem updating your subscription
• I cannot preview or apply any plan change from the pricing UI
• Codex is effectively blocked by usage limits
• I am not trying to purchase a new paid tier or add credits — I only want my account restored to the plan I had before the hackathon subscription override

What steps can reproduce the bug?

1. Start from an account that received the Paris hackathon / Build Week one-month Pro 5x override because credits checkout/redemption failed.
2. Wait until that one-month benefit expires.
3. Open https://chatgpt.com/#pricing or the Codex app plan/subscription UI.
4. Try to return to the original pre-hackathon plan (or any plan change).
5. Observe repeated UI error: There was a problem updating your subscription.
6. Open Codex and try to use it.
7. Observe usage-limit blocking and no usable reset path.

What is the expected behavior?

When the temporary one-month hackathon Pro 5x benefit ends, the account should automatically and cleanly revert to the user's original plan.

If manual action is required, the subscription UI should allow a normal downgrade/revert without forcing a new purchase, credit pack, or auto top-up.

The backend should not leave the account in an Enterprisey/Gratis state that cannot be previewed/updated via /subscriptions/update/preview.

Additional information

Related issues from the same account/history

This is a continuation of an ongoing subscription/account-state problem:

• #32978 — No Codex reset available and subscription update fails on Pro 5x during Build Week (open; documents the hackathon override, missing resets, and the same subscription update error)
• #27645 — Codex Paris workshop promo applies discount but checkout fails (open; original hackathon/workshop credit redemption failure)
• #22714 — Codex mobile Remote Control stale host issue (closed; separate, but same account history)

Timeline / context

1. Paris workshop / hackathon promo checkout failed (#27645).
2. Account was moved to a one-month Pro 5x benefit instead of normal credits (#32978).
3. During that month: no usable Codex usage resets, subscription page already failed to update.
4. Now (July 14, 2026): the one-month benefit has ended, but I still cannot revert to my original plan and Codex remains blocked.

What I am asking for

Please restore my account to my original pre-hackathon plan and clear the inconsistent Enterprisey/Gratis / expired-benefit billing state so that:

• subscription changes work again, or automatic revert completes,
• Codex usage reflects the correct plan entitlements,
• I am not forced into go/Plus/Pro upgrades or credit purchases.

I can provide account email, exact original plan name, promo code, invoices, and full unredacted logs privately to OpenAI Support if needed.
