Can the 5-hour limit block me if I still have weekly usage?

Yes. Where both limits apply, you need remaining allowance in both. You can hit the 5-hour limit before five hours have passed, even with weekly usage left.

Codex 5-Hour Limit Explained

Q: What is the Codex 5-hour limit?

Codex may enforce a rolling five-hour usage window in addition to a weekly allowance. The window starts when you send your first message after the previous window ends. Remaining capacity and the next reset time are shown in Settings → Usage or /status.

Q: When does the Codex 5-hour limit reset?

Your 5-hour reset time is account-specific. Open Settings → Usage or run /status in Codex. Third-party sites cannot calculate a private account’s exact 5-hour reset time.

The 5-hour limit is the short rolling window that can stop a session even when your weekly allowance is not empty.

Codex can apply a 5-hour usage window and a weekly allowance at the same time. If both apply, you need remaining capacity in both. Your exact 5-hour reset time is in Settings → Usage or /status — not on this page.

What is the Codex 5-hour limit?

OpenAI describes the five-hour limit as the amount of included usage in each short window. A new window starts when you send your first message after the previous window ends. You can reach the 5-hour limit before five hours have passed if that window’s allowance is used up.

This is why searches like “codex 5 hour limit reached” and “when can I use Codex again” usually mean: which window is blocking me?

5-hour vs weekly: which one is blocking you?

	5-hour limit	Weekly limit
Horizon	Hours — recovers inside a day	Days — the longer planning cap
Typical feel	Stopped mid-session	Out until the weekly reset
Can it block first?	Yes, even with weekly remaining	Yes, even after a 5-hour refresh
Where to check	Settings → Usage / `/status`	Same surfaces

Full model: How do Codex usage limits work?. If the 5-hour window has refreshed but you're still blocked, you may have reached your Codex weekly limit.

Personal vs public timing: Codex Reset Time.

What to do when the 5-hour limit is reached

Wait until the time shown in Settings / /status.
See whether a saved banked reset can refresh eligible windows.
Use credits or upgrade only if those options appear on your plan.
If weekly remaining is also 0, the 5-hour clock alone will not get you back in. See Limit Reached.

Codex 5-hour limit FAQ

Does a public Codex reset refill the 5-hour window?

A public automatic reset applies to the limits named in that announcement. A full banked reset refreshes both the 5-hour and weekly windows and changes the weekly reset date. Confirm in Settings after it lands.

Why did my 5-hour reset time change?

Using a full banked reset changes the weekly reset date; window timestamps can move after a refresh. Always re-check Settings → Usage.
