Codex Quota Exhausted? Decode 5-Hour vs Weekly Limits & Reset Options

When Codex shows "5-hour quota exhausted," don't immediately hunt for a one-click restore. First open ChatGPT's Settings → Usage to identify which limit you hit: the 5-hour rolling window, the weekly quota, or a specific feature cap. Each limit has its own refresh schedule; planning tasks around the shown refresh time is more reliable than repeatedly switching models.

Follow the Normal Refresh Path

For Plus users, Work and Codex share the same plan quota. Both the 5-hour window and the weekly window must have remaining allowance for tasks to continue. If only the 5-hour window is used up while weekly quota remains, wait for the 5-hour refresh time shown in the UI. The new window starts from the first request after the previous window ends — logging out and back in does not reset it early. If the weekly quota is also exhausted, you must wait for the weekly refresh. Task size, model choice, and reasoning tier all affect consumption, so you cannot infer remaining balance from a fixed number of prompts.

Use "Available Reset" Only When the UI Offers It

If the desktop Settings → Usage & Billing page or the web usage page shows an available storage reset, open the usage summary first. Confirm which limits it covers and when it expires before deciding to use it. The Codex CLI also exposes a /usage command that may show a redemption entry. A full storage reset for Plus restores both the 5-hour and weekly main quotas, but the entry point is only offered to eligible accounts; receiving an offer does not mean it activates automatically. If the relevant quotas are still ample, the UI may not allow redemption at all.

Compare Instant Reset and Credits Only When Urgent

Some individual Plus users see a "Purchase Instant Reset" on the desktop usage page, or a banner after the weekly quota is depleted. Read the price, remaining quota, and new refresh date carefully: paid reset takes effect immediately and cannot be banked — the next Work or Codex request starts a new weekly cycle. It is not extra credits. Hitting only the 5-hour cap may not trigger the weekly-exhaustion banner. Credits apply only to supported additional usage; the two mechanisms serve different purposes, so choose based on what your interface actually shows.

If usage numbers don't update, refresh the page and verify the logged-in identity and workspace. If a purchase was recorded but quota didn't restore, avoid duplicate purchases; keep the receipt and contact support. Pro 100, 200, and 500 plans currently have no 5-hour window for Work/Codex, so when you see a "5-hour recovery" tutorial, first confirm your own plan. A reset restores only the quotas within its coverage; it does not delete project files and cannot permanently raise the plan's hard limits.
