Reasoning models need a clear architectural brief

A note on o3-mini and two proposed review exercises: separate the evidence, assumptions and questions that remain open.

OpenAI introduced o3-mini on 31 January 2025 as a reasoning model oriented toward science, mathematics and coding. Its release documentation describes text input without image understanding. That makes it a useful reference for thinking about what a written architectural task must contain.

Exercise one: inspect a planning question

Provide the applicable, dated rules with the project quantities. Ask the assistant to separate stated facts, assumptions and missing information, and to show the calculation steps with a source for each rule.

The responsible designer must check those sources and calculations. A coherent explanation without the applicable references cannot establish project compliance.

Exercise two: outline a specification

Ask for a structure that identifies which performance values need confirmation. Supply approved values where they exist; leave missing ones explicit. The model should help organize the draft without inventing project requirements.

A useful output gives the architect and consultants something specific to review: the requirement, its source and the decision still needed.

Keep the review reproducible

  • Retain the supplied rules and project inputs with the draft.
  • Distinguish a quoted requirement from the assistant’s suggestion.
  • Check calculations independently before using the result.

The output we would assess in these two exercises is a draft whose sources can be followed. Another designer should be able to see what information the assistant used, what it assumed and which decisions remain open.
