What this error means

On ChatGPT Plus, the most capable models (e.g. GPT-4o / GPT-5 / advanced models) have a rolling message cap. When you hit it, ChatGPT limits that model for a few hours and usually offers a lighter model meanwhile.

Common causes

  • You sent many messages to a capped model in a short rolling window
  • Heavy use of advanced features (vision, large files, long context)
  • The free-tier limit on the advanced model is lower
  • Peak-demand caps are temporarily tighter

How to fix

  1. 1.Switch to the offered lighter model and continue
  2. 2.Wait for the cap to reset (often a few hours)
  3. 3.Spread heavy usage out over time
  4. 4.Upgrade to a higher plan (Pro) for larger caps
  5. 5.This is a usage limit, not an outage, but check the status above to be sure

When waiting helps (and when it won't)

The cap resets on a rolling window (commonly a few hours). Switch models to keep working, or wait for the reset.
