Hi @thorny glen. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
Hello! How can I help you with OpenAI today?

@limpid shell How many Questions can i ask GPT 5.5 as a Free Plan User
Let me check the knowledge base for you again. One moment! :books:
As a ChatGPT Free user, you can send:
- Up to 10 messages with GPT‑5.5 every 5 hours. After that, ChatGPT will automatically switch you to the mini version of the model until your 5‑hour window resets.[GPT‑5.5 usage limits]
Note: Some tools (data analysis, file/image uploads, image generation) have their own separate limits, in addition to this GPT‑5.5 message limit.[Free tier FAQ]

@limpid shell how many per week ?
Let me check the knowledge base for you again. One moment! :books:
The knowledge sources only specify that Free users can send up to 10 GPT‑5.5 messages every 5 hours; they do not state a weekly total limit.[GPT‑5.5 usage limits]
So I’m sorry, but there’s no information in these sources about an official per‑week cap for GPT‑5.5 on the Free plan.

@limpid shell ■ You've hit your usage limit. Upgrade to Plus to continue using Codex
(https://chatgpt.com/explore/plus), or try again at May 23rd, 2026 3:54 PM.
what's wrong ?
Let me check the knowledge base for you again. One moment! :books:
That message means you’ve hit a usage limit, not that something is broken.
From the docs:
- Codex usage “counts toward your agentic usage limit” and the number of messages you can send depends on your plan and how heavy your tasks are.[Codex usage limits]
- When you reach your Codex limit, you’ll see a banner and must either wait for the limit window to reset or upgrade / add credits (for eligible Plus/Pro/Business/Enterprise users).[[Codex usage limits]](https://help.openai.com/en/articles/11369540-using-codex-with-your-chatgpt-plan#usage-limits-by-plan;[What happens at limits](https://developers.openai.com/codex/pricing#what-happens-when-you-hit-usage-limits))
In your case, ChatGPT is telling you:
- You’ve exhausted your included Codex/agentic usage for your current window.
- You can either:
- Wait until May 23rd, 2026 3:54 PM for the limit to reset, or
- Upgrade to Plus (and then optionally buy credits) to continue using Codex immediately.[[Free tier FAQ]](https://help.openai.com/en/articles/9275245-chatgpt-free-tier-faq;[Credits in ChatGPT](https://help.openai.com/en/articles/12642688-using-credits-for-flexible-usage-in-chatgpt-freegopluspro)
Nothing is wrong with your account; you’ve just temporarily used up your Codex allowance for your plan.

@limpid shell but it has been 2 days, the limit doesn't reset
Let me check the knowledge base for you again. One moment! :books:
The knowledge sources don’t describe a Codex limit that should stay blocked for multiple days on a Free ChatGPT account, so I can’t say for sure why yours hasn’t reset.
What we do know:
- Free ChatGPT has time‑windowed limits (e.g., GPT‑5.5 is 10 messages per 5 hours), and separate, stricter limits for tools like Codex / data analysis / file uploads.[Free tier FAQ]
- Codex limits are based on 5‑hour and weekly windows, and can be exhausted quickly depending on how heavy your tasks are.[Codex pricing FAQ]
- There have been cases where Codex usage/limits behaved incorrectly and required a backend fix from OpenAI support.[Codex limit bug; Cloud task tracking fix]
Since your banner still shows a specific “try again at” time that has already passed, and the docs don’t explain a multi‑day lockout, this likely needs account‑specific support, not something you can fix yourself.
What you should do:
- In ChatGPT/Codex, use the in‑product help:
- Go to Settings → Help → Contact us (or the help widget) and include:
- Screenshot or exact text of the error
- Your plan (Free)
- That the “try again at” time has passed by 2+ days but the limit hasn’t reset
- Go to Settings → Help → Contact us (or the help widget) and include:
- If you’re using the Codex CLI/app, also send
/feedbackfrom the CLI as suggested by the Codex team.[Community guidance]
