Codex usage: check limits and reset times
Editorially updated · Independent guide
For your actual Codex allowance, use the official usage dashboard or /status in Codex CLI. WhenModelReset helps you interpret and save those times; it does not connect to your account or measure your usage automatically.
A quick reading checklist
| Account | Is this your intended personal account or workspace? |
|---|---|
| Allowance | Which window or feature is this number for? |
| Percentage | Does the label say used or remaining? |
| Time | Which date and time zone does the reset use? |
Worked example: 80% used
If the display says 80% used, 20% remains for that allowance. If it says 80% remaining, only 20% has been used. Do not average two windows: a weekly limit and a shorter limit each need their own label and reminder.
Why the tracker may disagree
An old manually entered value, a different workspace or an announcement about a future event can explain a mismatch. Refresh the official screen first, then update your saved time. The homepage burn-rate tool is a planning estimate; changing its slider does not change any account limit.
What to do
- Open the usage dashboard while signed in to the account you use for Codex.
- In the CLI, type /status when you want to inspect the active session and available limit information.
- Read the label beside each percentage: used and remaining have opposite meanings.
- Copy the reset date and time zone into your personal reminder, then check it again after any reset event.
Scope & exceptions
- A subscription usage display and API billing are different views. Use the dashboard for your authentication method.
- A browser-side estimate is only as accurate as the values you enter. It is not an official balance.
