What are Codex usage limits?

Codex may apply a rolling 5-hour usage window and a weekly allowance. Where both apply, you need remaining capacity in both. Exact remaining usage and reset times are in Settings → Usage or /status.

How do I check Codex usage limits?

Open Settings → Usage on desktop, web, or CLI. In an active Codex CLI session, run /status. Those surfaces show which allowance is exhausted and the reset time.

Does a public Codex reset refill my limits?

A public automatic reset applies to the limits named in the announcement. A full banked reset refreshes 5-hour and weekly windows and changes the weekly reset date. Eligibility varies by offer and plan.

Codex Usage Limits Explained

Codex is not one daily quota. A practical map of 5-hour windows, weekly limits, and public resets. For the question-form guide, see How do Codex usage limits work?.

Your remaining usage and reset timestamps are private. Check Settings → Usage or run /status. This page explains the model; it does not compute your account’s numbers.

Codex has more than one limit

5-hour usage window — rolling; a new window starts after the previous one ends. Dedicated: Codex 5-Hour Limit.
Weekly allowance — the longer cap. Dedicated: Codex Weekly Limit.

Where both apply, you need remaining allowance in both to continue. Limits vary by plan, model, and task — published message counts are only estimates.

Rate limit vs usage limit

People also search “Codex rate limit”. In practice the banner you care about is usually a usage window (5-hour or weekly), not a burst rate-limit on a single API call. If the product says usage limit reached, start with what to do next.

Codex usage limits FAQ

Plus vs Pro usage limits

Included volume differs by ChatGPT plan. This site does not republish unofficial message tables as if they were your quota. Trust Settings → Usage for the plan you actually have.

Did my limits reset?

Re-open Settings after the timestamp, or after a public announcement lands. If it still looks wrong: reset not working.

Plan around Codex limits, not against them

AI Limit monitors public Codex reset signals and sends an alert directly to your iPhone. It does not read your private ChatGPT / Codex remaining usage.
