AI Concepts
Reasoning Model
Definition
AI models specifically designed to break down complex problems into steps and reason through them before answering. Examples include OpenAI's o3/o4 series, DeepSeek R1, and Gemini Deep Think. They trade speed for accuracy on hard problems.
In Plain English
AI models that "think harder" before answering. Instead of blurting out the first answer, reasoning models take extra time to work through problems step by step — like how you'd solve a hard maths problem on paper rather than in your head.
