Feature Request: Maximum Reasoning Mode - - Deeper Analysis and Self-Verification

The new deeper-thinking feature is a major improvement, and I genuinely appreciate the progress. However, I believe ChatGPT could go much further.

I would like to see a dedicated “Maximum Reasoning” / “Deepest Analysis” mode where the priority is not response speed, but the highest possible quality, accuracy, and reliability.

The goal should not simply be to make ChatGPT “think longer.” It should be able to reconsider its approach, challenge its own assumptions, detect mistakes, and improve its answer before submitting it.

For complex tasks, I would like ChatGPT to perform an internal verification process such as:

- Did I correctly understand the user’s actual goal and every important requirement?

- Did I miss any part of the request?

- Are my conclusions logically consistent?

- Are calculations, formulas, dates, units, and tables correct?

- Did I make an unsupported assumption?

- Is there a better or more accurate way to solve the problem?

- Did I properly verify important factual claims?

- Does the final answer actually satisfy the original request?

This would be especially valuable for research, legal documents, calculations, data analysis, Excel/spreadsheets, programming, and other complex tasks where one small mistake can compromise the entire result.

I would also like the model to be able to recognize when a task deserves substantially more reasoning than a normal request. For example, a simple question should remain fast, while a complicated multi-step task could automatically trigger a much deeper reasoning process.

An ideal implementation would provide several reasoning levels, such as:

Fast → Deep → Maximum

With Maximum explicitly optimized for quality over speed.

Most importantly, I want the model to think about its own process, not merely produce a longer chain of reasoning. The real improvement would be a system that can recognize uncertainty, revisit weak assumptions, verify its work, and deliberately improve the final result before presenting it.

I believe this could make ChatGPT significantly more reliable for serious professional and research work.

Thank you for continuing to improve the reasoning capabilities of ChatGPT. I hope a true maximum-depth reasoning and self-verification mode can become a future feature.
