AI Glossary / Reasoning models

🏗️ Models and training

Reasoning models are a generation of models that conduct extensive internal reasoning before answering - they consider options, check their own conclusions and only then formulate a result. In difficult math, programming and planning, they can outclass regular models. The price is time and cost: "thinking" consumes additional tokens, so responses take longer and cost more. That's why many tools let you choose a mode - fast for simple questions, reasoning for tasks where accuracy matters.
