Codex Usage Limit

Direct answer
Codex enforces usage limits through two mechanisms: a rolling 5-hour window that smooths bursts and a weekly limit that caps total usage across seven days. Some accounts also receive banked resets. Your current limits, remaining quota and reset times are individual — the /status command in Codex shows them exactly.
The two limits that matter
The 5-hour limit constrains short-term intensity; the weekly limit constrains total volume. Hitting either one pauses usage until that window frees up. Limits can also vary by plan, so the authoritative source for your numbers is always /status on your own account.
Staying inside your limits
Track your remaining quota after each work session and compute your burn rate. If your weekly quota is draining faster than the window refills, cut daily usage to the safe budget the calculator recommends, and set a reset alert so you know the moment capacity returns.
Frequently Asked Questions
What is the Codex usage limit?
A combination of a rolling 5-hour usage window and a weekly cap. Exact amounts depend on your plan and are shown by /status.
What happens when I hit a Codex usage limit?
Usage pauses until the relevant window frees up — the 5-hour window refills continuously, the weekly limit at your weekly reset.
How do I check my Codex usage limit?
Run /status in Codex. It shows remaining quota and reset times for both windows. Paste it into the Quota Tracker for a dashboard view.
