You find out where your Codex limit is the worst way. Halfway through a task, when Codex stops and tells you to try again later.
Codex will tell you where you stand if you ask. Type /status in the CLI, or open the usage page at chatgpt.com/codex/settings/usage. The trouble is remembering to ask while you are deep in the work.
What the board shows
The AI usage widget draws your Codex plan as rings. One for the current five-hour window, one for the week. Each ring empties as you use it, turns amber under half and red under a fifth, and says when it comes back, like “resets in 2h 14m” or “resets Thu 2:00 PM”.
It draws the windows Codex reports for your plan. On Plus that is a five-hour window and a week. OpenAI says Pro plans currently have no five-hour limit, so there the week is the one to watch.
Claude Code sits beside it in the same widget, read the same way. So when Codex is down to 15% of its week and Claude Code still has 70%, you know which one gets the next big task.
Where the numbers come from
Codex already knows your limits. Each time it runs, it hears from OpenAI how much of the window and the week you have used, and keeps that count in its own session files on your computer.
The board’s runner, a small program you set up once with one line, reads the newest of those counts and sends your board the percentages and reset times. Nothing else. Not your prompts, not your code, not what Codex wrote back. The widget says when Codex last checked, so a number is never older than it looks.
One thing to know. The count moves when Codex runs on a linked computer. OpenAI says local and cloud use share one allowance, so after an hour of Codex in the cloud, the rings catch up the next time Codex runs on your machine.
Codex usage at a glance
/status answers inside one terminal, when you remember to type it. /statusline can keep your limits in the CLI’s footer, which helps, as long as you are looking at that terminal. A board answers when you glance at it, whichever window you are in.
Every new account gets an Agents board with the usage widget already on it, beside your Codex and Claude Code sessions, the one waiting for your OK and today’s commits. Put your revenue next to it, or anything else you check in a day.
If you run Codex on more than one computer, or on a server, link each one with the same line. Usage and sessions come from all of them.
