  • On the ChatGPT platform, Plus and Team users now enjoy tripled daily message limits (increased from 50 to 150 messages), while free users can try it out via the “Reason” option.

In my (admittedly short) time with the model, I’ve noticed that it does get stuck every now and then, but it just feels like a significant upgrade to the already great o1 and o1 mini models. But before I get into some basic prompt guides, what is a reasoning model and when should you use it?

What’s a “Reasoning model” anyway? :

A really simple metaphor is to imagine a reasoning model as a chef who doesn’t just serve a dish but first meticulously plots out each ingredient and step that he or she is going to take to cook that dish in their head, ensuring every flavor complements the next (plus the chef has some guidelines on what combinations don’t work together) before actually cooking. By breaking the problem up it creates all kinds of intermediate solutions and outputs which the chef can use on his way towards a more complicated final dish. Unlike a standard language model like ChatGPT4o that simply mix ingredients based on learned recipes, the reasoning model has an internal dialogue first and breaks complex recipes and techniques into logical, manageable steps. This deliberate process, often referred to as “simulated reasoning”, allows the model to check its work before it outputs everything to the user. The end result is that reasoning models reduce errors and enhance accuracy on intricate tasks such as math puzzles, coding challenges, and scientific queries.

How to Prompt a reasoning model ?

So if you are still reading, then you can agree that O3-mini is not the same as ChatGPT or any other conventional language model. So it also stands to reason that we interact with it in a different way. Reasoning models are great at really tough “zero shot” problem solving, because they are taking all these intermediate steps along the way to producing the output. To get a really good zero shot result though, you need to write a MUCH longer prompt ! Here is the Rosetta stone for a reasoning prompt:

And remember o3-mini also has search capabilities, so switch those on if you want to boost your reasoning model even further !! (just remember to specify how you want the output to be returned).

(you can ask a standard language model to create this prompt for you by the way, if you’re feeling particularly lazy).

The ingredients are:

  1. A Clear Goal — Defining what the output should achieve ensures that the model stays on track.
  2. A Well-Structured Return Format — By specifying what kind of response is needed (lists, summaries, specific fields), the output becomes more useful and actionable.
  3. Warnings for Accuracy — The model can generate plausible but incorrect information, so including accuracy checks (like verifying study sources or Unity-specific syntax) helps reduce hallucinations.
  4. Context Dump — This part grounds the model in your specific needs. It prevents generic answers by giving the model important constraints and preferences.

And here are some examples of some reasoning prompts:

Example: Research Assistance with Verified Sources

Prompt:

Goal: I need a summary of the latest scientific research on how intermittent fasting affects cognitive function, based on studies from the last 3 years.

Return Format: For each study, include:

  • Study title
  • Authors and publication year
  • Key findings in 2–3 sentences
  • The type of study (e.g., meta-analysis, clinical trial, observational)
  • A link to the full research paper if available

Warnings: Make sure the studies are from peer-reviewed journals and not just opinion pieces or low-quality sources. Do not include outdated research from before 2020. If human trials are not available, note that the study is based on animal research.

Context Dump: I’m writing an article on the effects of fasting on brain function and mental clarity. I already know the basics about how fasting influences insulin sensitivity and autophagy, so I’m more interested in new discoveries about how it affects memory, focus, and long-term cognitive health. If possible, include any research on how fasting impacts neurotransmitters, brain inflammation, or neuroplasticity.

The Reasoning step in 03-mini:

When I put this big ol’ prompt in 03 mini it really went to town ! Here are the steps it took before output. An additional note here, the model actually backtracked, which I’ve never seen o1 or o1 mini do before. It was almost ready to output and then it stopped and went back to the drawing board !!
