How do I check how much Codex or Claude usage I have left?
Claude: type /usage in Claude Code, or open Settings › Usage on claude.ai. Codex: open chatgpt.com/codex/settings/usage, or type /status in the CLI or the VS Code extension. Each one shows how much you have used and when it resets. whenreset tracks the resets a vendor gives everyone, not your own usage.
Codex
Open the usage page at chatgpt.com/codex/settings/usage, or type /status in the CLI or the VS Code extension.
The usage page has the most: which allowance has run out, your credit balance and each reset time. You can also reach it from Settings. While working in the CLI, type /status to see the limits you have left in the current session; in the VS Code extension, type / in the input box and pick /status, which shows your rate limits. /usage in the CLI is something else: it shows token usage by day, by week and in total, and it is where you use a banked reset. To keep the limits in view, run /statusline in the CLI and add them to the status line at the bottom.
What the official docs say
You can find your current limits in the usage dashboard. If you want to see your remaining limits during an active Codex CLI session, you can use /status.If you're nearing or have reached a Codex limit, open Settings or your usage dashboard. Check which allowance is exhausted, your credit balance, and any reset time shown. In an active Codex CLI session, enter /status.These estimates are not fixed message limits; check your usage dashboard for current limits and reset times./status: Show the chat ID, context usage, and rate limits./usage: View account token usage or use a rate-limit reset. Inspect daily, weekly, or cumulative ChatGPT token activity from inside the TUI.Claude
Type /usage in Claude Code. On the web and in the apps, open Settings › Usage (claude.ai/settings/usage).
The /usage panel currently shows three bars, labelled on the panel as Current session (the 5-hour limit), Current week (all models) (the weekly limit), and one more weekly bar for a single model. Which model gets its own bar changes over time, so go by what your panel says. Each bar is followed by Resets and a time. /cost and /stats are aliases for the same panel. In the VS Code extension, /usage opens the Account & usage dialog. On claude.ai, Settings › Usage starts with Plan usage limits, which shows the time left in the current session and when the weekly limit resets.
What the official docs say
/usage: Show session cost, plan usage limits, and activity stats. On a Pro, Max, Team, or Enterprise plan, includes a breakdown of what counts against your plan limits. /cost and /stats are aliases.If you're using a Pro, Max, Team, or seat-based Enterprise plan, you can navigate to Settings > Usage to view progress bars showing how much of your five-hour session and weekly usage limits you've consumed.Current session: How much of your plan's five-hour session limit you've used thus far, plus the amount of time remaining in the session.Run /usage to open the Account & usage dialog.It shows your signed-in account, your plan, and usage bars for your plan's limits, such as the current session and the week. Each bar shows how long until its limit resets.Which time zone are reset times shown in?
Claude Code shows them in the time zone of your machine, and the /usage panel writes the zone after the time, for example Resets 12:30am (Asia/Singapore), so there is nothing to convert. If you have changed time zones or are working on a remote machine, read the zone in the brackets.
OpenAI does not document a time zone rule for the Codex usage page, so go by the time the page shows. When you ask OpenAI support about a limit, they ask you to include your time zone.
What the official docs say
Include the limit or credit balance you're questioning, the reset time shown, a screenshot, the Codex client and model, and when it happened—including your time zone.Common misconceptions
- whenreset can show how much usage I have left
It cannot. whenreset does not connect to your account; it records the resets OpenAI and Anthropic give everyone, and the expected next one. Your own usage and reset times exist only in the official places: /usage and Settings › Usage for Claude, the usage page and /status for Codex.
- In the Codex CLI, /usage shows the limits I have left
No, that is /status. /usage in the CLI shows token usage by day, by week and in total, and lets you use a banked reset. OpenAI points to /status or the usage page for remaining limits. Claude Code is the other way round: /usage shows your limits, and /status shows the version, model and account.
- If the bar is not full, I will not be limited
Not true. The 5-hour limit and the weekly limit are two lines drawn down at the same time, and whichever fills first stops you. Claude adds a separate weekly bar for one model. Watching a single bar misleads you; look at all three.
In practice
- Check before you start a long task. Type /usage in Claude Code or /status in the Codex CLI. It takes seconds, and it beats being cut off halfway.
- See which bar is full before deciding what to do. If it is the 5-hour one, wait a few hours. If it is the weekly one, look at your weekly reset time, or check whenreset for a recent reset for everyone.
- To keep it in view: in the Codex CLI, /statusline adds your limits to the status line at the bottom. A custom status line in Claude Code can show 5-hour and weekly usage too.
- The lower half of /usage in Claude Code shows where your usage went: skills, subagents, plugins and MCP, with long context and cache misses flagged. That part counts this machine only, not your other devices or claude.ai. The bars at the top cover the whole account.
- Claude Code shows reset times in the time zone of your machine, and /usage writes the zone after the time.
- whenreset tracks resets given to everyone and cannot see your account. For what you have left and when it resets, go by the official places above. What whenreset tells you is whether a free reset happened recently.
