ChatGPT Plus vs Pro: Codex and Work limits, explained
Short answer: On Plus, Codex and ChatGPT Work have a 5-hour window and a weekly limit, and you need room in both. Pro $100, $200 and $500 currently have no 5-hour limit in Work and Codex, but they still have an included weekly allowance. [1]
How the windows work
- 5-hour window: a new window starts with your first Work or Codex message after the previous window ends. [1]
- Weekly limit: caps how much included work you can do over the weekly period. [1]
- Local messages and cloud tasks share your plan's allowance. [3]
- Check what's left in Settings → Usage, or run
/statusin the Codex CLI. [1][2]

Not published: OpenAI does not publish exact weekly caps or 5-hour message counts for Codex and Work. Usage varies by model, task complexity and context. [2][3]
Resets: banked, purchased and global
- Banked resets are promotional one-time resets saved to your account. Using one refreshes your 5-hour and weekly windows and moves your weekly reset date. [5]
- Purchased instant resets are available to some Plus and Pro accounts, depending on billing country. They apply immediately and can't be saved. [1]
- Future resets are not guaranteed. [5]
When you hit a limit
You can add credits, apply an available reset, upgrade, or wait. Switching to a lower-cost model makes the allowance last longer. [2][3]
