How to Check Codex Usage Limits and Remaining Quota
Check the allowance that is actually limiting you before waiting or changing plans.
Direct answer: In the Codex CLI, run /status to see your remaining quota and reset time. You can also open the official usage dashboard in ChatGPT to review the current limits and reset times shown for your account. This page cannot read private account usage.
Use this page when: you need to find the right usage screen or understand what its counters mean. You can also estimate a sustainable weekly usage pace from the numbers shown there. If Codex already says the limit is reached, use the limit-reached decision guide. If the displayed time has passed but access has not returned, use the reset-time guide.
Where to check Codex usage
| WHERE | WHAT IT SHOWS | USE IT FOR |
|---|---|---|
Codex CLI: /status | Active allowance, remaining usage, and reset time | A quick check while working in a session |
| ChatGPT official usage dashboard | Account and plan limits, reset details, and any visible options | Confirming the account-level source of truth |
| OpenAI API platform dashboard | API-key usage and billing data | Checking API usage, not subscription Codex quota |
Subscription usage is not API usage
Codex subscription usage and OpenAI API usage are different products and different accounting surfaces. A paid ChatGPT or Codex plan does not make API dashboard numbers a substitute for the allowance shown by /status or the official usage dashboard. For current product and plan context, see the official OpenAI pricing documentation.
What affects remaining usage?
Remaining usage is not a universal message count. It can vary with the selected model, task complexity, context size, reasoning effort, and tool calls. Local CLI work and cloud chats draw from the applicable shared plan allowance, while weekly limits may also apply. Use the percentage and time shown in your own account instead of assuming a fixed number of prompts or a fixed weekly schedule.
How to read the numbers
Read the allowance name, remaining percentage or quota, and the reset time as one record. Model, task complexity, context, and local versus cloud work can change how quickly usage is consumed, so a percentage is not a universal prompt count. A session window and a weekly allowance are separate counters and may show different times.
The API dashboard is not a substitute for subscription usage. API keys use separate billing and accounting. For current plan context, see the official OpenAI pricing documentation.
Frequently asked questions
How do I check my remaining Codex usage?
Run /status in a Codex CLI session, or open the official usage dashboard to see the active allowance, remaining quota, and reset time shown for your account.
Is Codex usage the same as API usage?
No. Subscription usage in Codex and ChatGPT is separate from API-key usage, which is tracked in the OpenAI platform dashboard and billed under API terms.
Why did my session limit reset but my weekly limit did not?
The short session window and the weekly allowance are separate counters. Check each allowance and its own reset time in /status or the official usage dashboard.
Can I reset my Codex usage limit early?
The available choices depend on your account. When a limit is reached, the product may show options such as waiting, buying credits, applying an available reset, or upgrading. Follow the options visible in your account.
