## Environment

- Surface: Web / iOS / macOS
- Affected feature and model, if relevant: GPT 6 Pro

## Bug

Repeatedly, a request for GPT 6 Pro leads to ‘Thinking failed’ errors. In fact, this happens on more than 50% of my queries, and leads to hours of wasted effort.

This is extremely frustrating.

Has been happening for months.

## Screenshots

This has been happening for me recently as well. Almost every prompt I send fails.

My last day to use up my 200 pro 6 messages, and everything is failing. Money back please

you can’t use 200 messages if they keep rate limiting you for even the ones that fail LOL

what a great way to save on compute! @OpenAI_Support !

</div>

There is now an official status incident that overlaps part of this thread, which gives us a useful timing boundary.

OpenAI Status recorded **“Elevated Error Rates on GPT-6 Astra Pro”** on September 24:

- identified: about **18:59**
- monitoring after mitigation: about **19:32**
- resolved: about **19:46**

That overlaps the evening reports here around 19:12 and 19:18, so those failures should be treated as incident-confounded rather than clean evidence of some separate account-specific cause.

But it does **not** explain the whole report, because the original post says the “Thinking failed” problem has been happening for months and on more than half of queries.

So I would split the evidence into three windows:

1. **before the official Sep-24 incident** ;
2. **during 18:59–19:46** ;
3. **after the status page says the incident was resolved**.

The most useful next evidence is not another large batch of attempts. It is one naturally occurring post-resolution failure with:

- exact local timestamp/timezone;
- selected model/mode;
- surface (Web/iOS/macOS);
- exact “Thinking failed” text or screenshot;
- whether the failed request still consumed one of the Pro-message allowances.

If failures continue after the official recovery window, that separates the chronic issue from the known Sep-24 outage.

And I would keep “Thinking failed”, rate-limit accounting, and model-routing/substitution as separate questions unless native evidence actually ties them together.

This issue is persistent - it existed before, and continues to exist after that incident.

Here’s a screenshot of a conversation I just had with GPT 6 Pro. Why do I have to ask it to continue over and over again? It’s extremely frustrating.
