Codex Usage Limits for ChatGPT Plus

Plus includes Codex, but it is not unlimited. You still have a rolling 5-hour window and, on most accounts, a weekly cap.

On ChatGPT Plus, Codex and ChatGPT Work share one included allowance. OpenAI publishes estimated local-message ranges per five-hour window by model — not your remaining quota. Check Settings → Usage or run /status for this account.

What Plus includes

Codex is included with Plus. Usage depends on model, task size, reasoning, and whether the turn runs locally or in the cloud. Cloud chats can consume more of the same five-hour window than a short local message.

Where both windows apply, you need remaining capacity in the 5-hour limit and the weekly limit.

Plus vs Pro

Pro plans include a larger multiple of the Plus allowance (commonly described as 5× or 20× depending on the Pro tier). If you hit Plus weekly walls most weeks, see Codex Pro limits and how to increase a Codex limit.

Do not treat a blog’s message table as your remaining %. Official ranges change with models.

How to check a Plus Codex limit

  1. ChatGPT → Settings → Usage
  2. Codex CLI → /status
  3. Confirm you are on the Plus account / workspace that hit the banner
