GuideCodex usage limit
Codex usage limit reached? Here is what to do.
Codex on a ChatGPT plan runs on usage limits. Every plan has a weekly limit, and some plans, such as Plus, also have a window that resets every five hours. When one runs out, Codex stops and says when it resets. You can wait, buy more, switch to an API key, or carry on with another agent you already pay for, which is what Lunchbox does for you.
ACheck what is left
Inside Codex
Type /status in a Codex session. It shows how much of each limit you used and when each one resets.
In ChatGPT
The usage page in Codex settings on chatgpt.com shows the same limits and reset times.
Why it went fast
Larger models use more of a limit per message than smaller ones, and long tasks with many files use more than short questions.
BYour options
Wait for the reset
The message and /status give the time. Starting a new session does not refill the limit.
Buy more
ChatGPT plans can add credits for Codex, which keep you going until the reset.
Use an API key
Codex can sign in with an OpenAI API key instead of your plan. That bills per token and does not touch your plan limits.
Pick a smaller model
A lighter model uses less of what is left, so the rest of the window lasts longer.
Carry on with another agent
If you also pay for Claude, Gemini or Grok, those agents have their own limits. The hard part is moving the task, because the new agent starts knowing nothing.
CHow Lunchbox handles it
The next agent takes over
In a Lunchbox room, when Codex runs out mid task, the next agent in your crew, for example Claude Code, picks up the same task with a briefing of everything the room knows.
Codex comes back
Lunchbox shows when the limit resets and brings Codex back after it.
See it coming
Pool shows what is left in every plan's windows and when each resets, read through each tool's own login.
DQuestions
How do I check my Codex usage?
Type /status in a Codex session, or open the usage page in Codex settings on chatgpt.com. Both show what is left of each limit and when it resets.
Does the Codex limit reset every 5 hours?
On plans with a five hour window, such as Plus, yes. Every plan also has a weekly limit, which resets once a week.
Can I keep working when Codex hits its limit?
Yes. In Lunchbox the next agent in your crew takes over the same task with the same memory, and Codex comes back after its reset. Lunchbox is free for Mac, Windows and Linux.
