In plain language
A reasoning model is designed to spend more effort on multi-step problems. This describes what the model or system does, not a promise that every product behaves identically.
An analogy
It is the difference between answering immediately and working through a difficult problem step by step.
The analogy is a shortcut, not a complete technical definition.

Should you care?
Consider it for hard tasks. Simple classification, rewriting or short answers may not justify extra latency or cost.
How it differs
A reasoning model is not automatically best for every task and can still make mistakes.
