How Do ChatGPT Usage Limits Work?

“ChatGPT limit reached” is often a chat messaging cap — not the Codex 5-hour / weekly windows, even on the same Plus or Pro account.

ChatGPT plans include several meters. Consumer chat models can have their own messaging limits. Codex and ChatGPT Work share a different allowance when those features are on the plan. Open Settings → Usage and read which product the bar belongs to.

Do not mix the two dashboards

If Codex CLI /status still has remaining but ChatGPT web is blocked, you likely hit a chat cap. If ChatGPT chat works but Codex is blocked, you hit the Codex / Work pool.

Plan-specific Codex pages: Plus · Pro · Work.

How to check ChatGPT usage

  1. ChatGPT → Settings → Usage
  2. Note model family, messaging remaining, and any reset time on that bar
  3. If you also use Codex, scroll / switch to the Codex / Work section instead of assuming it is the same number

When ChatGPT usage resets

ChatGPT messaging windows are account- and model-specific. Trust the timestamp on that bar. For Codex personal vs public resets, use Codex reset time.
