⏱️ The 5-hour window: how not to wait
Claude (in the chat, the app and Claude Code) and, with ChatGPT, for example Codex on the Plus plan count usage in 5-hour windows. The window starts with your first message. When you use up the limit in 2 hours, you wait the remaining 3 hours for the next window to start.
My tip: send the AI a short message, like “hi”, 2–3 hours before you start working. The window starts running while you're doing something else. When you then run out of the limit while working, a new window starts shortly and you can carry on. Altogether you get 4–6 hours of work without a forced break.
- It won't get you more usage. Paid plans also have a weekly limit. The tip only moves the waiting to a time when you're not working anyway.
- How much you have left: in Claude under Settings → Usage, in Claude Code the command
/usage. In other AIs, look in the settings for Usage or Limits.
- The limit rules change. As of 25 October 2026.
