A Hands‑On Test Drive: From Math Puzzles to Coding Mastery
One of the most exciting aspects of the new release is how it handles test scenarios that previously stumped older models. Let’s walk through a few examples to see the transformation in action.
Testing Basic Arithmetic
Consider a simple test: “Which is bigger, 9.11 or 9.9?” Previous versions like the 01 mini had occasionally miscalculated or given incomplete answers. However, when this query was posed to 03 Mini, the response was both prompt and accurate. In just four seconds, the new model not only provided the correct answer—“9.9 is larger than 9.11”—but also demonstrated the thought process behind the calculation.
Tackling a Complex Puzzle
The next test involved a multi‑step problem: “A horse costs 50, a chicken costs 20, and gold costs 40. You bought four animals for a total of 140. Which combination did you buy?”
Here, 03 Mini was challenged to provide not one but two viable solutions. While older models might have produced an incomplete answer, the new model walked through the reasoning process step‑by‑step, ultimately presenting both combinations:
-
-
-
-
- Option 1: Zero horses, one chicken, three goats.
- Option 2: Two horses, two chickens, zero goats.
-
-
-
By showing its working process and covering all potential correct solutions, the model not only passed the test—it set a new benchmark for reasoning clarity.

The Coding Challenge: Building a Chess Game
One of the most striking demonstrations of the 03 Mini High variant is its ability to handle complex coding tasks. In a recent test, a user requested the model to generate a working game of chess that could run locally on their computer. The task was multifaceted: it wasn’t just about writing code but also ensuring that the code implemented logical game mechanics and proper asset management.
How the Chess Game Code Works
When tasked with creating the chess game, the model provided code that outlined the movement rules for different chess pieces (pawns, bishops, queens, etc.) and even indicated how to detect game‑ending conditions like checkmate. The user later prompted the model to incorporate an advanced feature—combining web search with its reasoning—to find appropriate chess piece graphics.
In our test drive, the chess game not only ran smoothly but also responded correctly to user inputs. When the user made a move, the game recognized legal moves, and upon reaching a checkmate situation, it appropriately prevented further moves—showing that the model can generate not just code, but well‑structured, logically sound code.
Merging Reasoning with Web Search in ChatGPT 03 Mini and 03 Mini High
One standout feature in this new release is the integration of web search with the reasoning model. Previously, ChatGPT’s reasoning capabilities were confined to its internal knowledge base. Now, however, users can enable search mode to have the model find external assets or additional data.
For example, after generating the initial chess game code, the user asked the model to locate proper chess piece images. The model quickly provided a link and detailed instructions:
-
-
-
- Search Results: The model combined its reasoning with a live search query, yielding a URL where high‑quality chess piece images could be downloaded.
- Asset Organization: It then recommended saving these files in a folder named assets—a crucial step for the game to locate and load the images.
