Reasoning Model

In one sentenceA model that "thinks" step by step before answering. Slower, but much better at complex problems.

What it means

Reasoning models spend extra time working through a problem internally (planning, checking, reconsidering) before they give a final answer. Some apps show this as "thinking".

They shine at strategy, math, analysis, planning and multi-step tasks. For a quick rewrite, a standard model is faster and just as good.

How to use it

• Use a reasoning or "thinking" mode for: pricing decisions, analyzing a spreadsheet, building a 90-day plan, comparing contracts.
• Give it the whole problem and the constraints, then let it work. Do not micro-manage the steps.
