Reasoning models represent an advanced approach to AI that enables more sophisticated problem-solving capabilities. Cohere's reasoning models are _hybrid_, meaning reasoning can be enabled (in which case they generate internal reasoning processes before delivering their final responses) or disabled (in which case they function the way any other LLM would).

This architecture makes reasoning models particularly valuable for applications requiring high accuracy, transparency in reasoning, and the ability to handle complex, multi-faceted problems that benefit from systematic analysis.
