5 prompts to try first in ChatGPT o-3 mini-high
Sometimes you just need an extra boost, and in the case of ChatGPT, this is where the o-3 mini-high model comes in. The o3 mini-high model takes more time to analyze problems, offering higher intelligence and more thorough responses — particularly for STEM-related topics.
Whether that’s crafting blocks of code or solving a logic puzzle, your best bet at achieving high-quality results is by using this model that’s built for science, math, and coding. While ChatGPT-4o remains perfectly suitable for most everyday tasks, it’s useful to know there are more powerful options out there.
1. Create a website using HTML and CSS
Are you ready to create your own website? With a simple prompt, you can ask ChatGPT o-3 mini-high to use its coding skills to create a website using HTML and CSS, two languages used to structure the content and style of a webpage.

For example you can use this prompt: Create the HTML and CSS code for a sleek portfolio website to showcase the photos I take as a wedding photographer.
2. Solve a logic puzzle
Asking ChatGPT-4o to find a 5-digit number that, when multiplied by 5, yields the original number with its digits reversed yields a reply: 17985. However, ChatGPT o-3 mini-high correctly concluded that there is no 5‑digit number that satisfies the condition.

The prompt for this task could be: Find a 5-digit number that, when multiplied by 5, yields the original number with its digits reversed.
3. Design a game using Python and Pygame
Who said coding can’t be fun? What better way to make use of this model’s coding capabilities than asking it to create an original game for you?
To create your own game using AI try type: Design a novel, interactive game using Python and Pygame.

4. Refine business models and conduct SWOT analysis
Since Plus users of ChatGPT have limited usage of o3‑mini‑high, it may be worthwhile to refine prompts with less powerful models before asking your final queries to o3-mini.
For example, you can first ask ChatGPT-4 to create a business model for a bookstore and then switch to o3‑mini‑high for a detailed SWOT analysis using the prompt: You will be provided with a business model for a bookstore. Your task is to critically analyze it and provide a detailed SWOT analysis.
5. Test logical reasoning with LSAT question
The standard ChatGPT-4o model remains great to handle most tasks, including determining the correct answer to questions testing your logic. However, if you want to be sure you’re studying correctly, switching to o-3 mini-high may be a wise decision.
The prompt for this task can be a sample LSAT question like: The organizer of a book club must select at least five and at most six works from a group of nine works...

Spoiler alert: The correct answer is 1.
