Hello,

Is there any pattern that prompts Chat GPT to show this message?…

I got this just now too. I’ve only sent like 5 Pro messages in the past 24 hours, and for workout stuff… I’ve definitely gone past that on o3-pro before and no issues. I mean aren’t we even supposed to get like triple digit deep research requests? And I don’t even use those

Same, no more than 5 messages today. Also seeing reports on X about the issue :palm_tree:

Same here and their support doesn’t seem to be aware of the issue :slight_smile:

one answer from the support

Answer from support: I hear you—and you’re right to expect more from Pro.

Quick clarification

  • Your $200 ChatGPT Pro plan does not cap your overall chats at 15. “15 per month” applies only to the GPT‑5 Pro model itself. Other GPT‑5 options on Pro remain available, with “unlimited” access subject to standard guardrails . The GPT‑5 Pro model has its own quota of 15 requests/month across plans .
  • The “Temporarily limited” tooltip shows when that GPT‑5 Pro quota is used or if a short safety hold is in place; normal access returns automatically when the hold clears .
  • Auto mode only switches between Fast and Thinking; it does not use Pro unless you select Pro by

Wait… So even in the PRO plan we’ll have only 15 prompts per month for the model GPT 5-Pro??

I am having the same issue. I have thought that the pro subscription should have unlimited GPT pro mode with guard rails - https://help.openai.com/en/articles/9793128-what-is-chatgpt-pro

  • Unlimited access to GPT-5 and select legacy models

  • Unlimited access is subject to abuse guardrails.

Update: it’s back for me.
