How to Increase Codex Usage Limits

First identify whether the 5-hour window or the weekly cap is empty. The right fix depends on which clock blocked you.

You cannot raise a private remaining % from this site. Official options usually are: wait until Settings → Usage shows a reset, redeem a saved banked reset, purchase an instant reset if eligible, add credits, or upgrade the plan. A public Codex reset only helps if the announcement covers your plan.

1. Confirm which limit you hit

If you are stopped mid-session with weekly remaining, wait on the 5-hour timestamp. If a 5-hour refresh does nothing, you need the weekly clock — or an increase option below. Guide: limit reached.

2. Wait, banked reset, or purchased reset

3. Credits or upgrade

Eligible Plus and Pro users can buy credits without changing plans. Business workspaces may allow extra Work / Codex usage on workspace credits after included limits. Upgrading Plus → Pro (5× / 20×) raises included volume; it is not unlimited. See Plus and Pro.

4. Public resets are not a plan upgrade

A global or promotional reset is not guaranteed and may not cover your seat. Check the live public tracker, then re-open Settings. If the private clock looks stuck: reset not working.
