Reasoning model

Also called: reasoning, reasoning models, thinking model, extended thinking, thinking mode, reasoning tokens, thinking

A model, or a mode of a model, that works through a problem in intermediate steps before it answers. The extra thinking takes more time and uses more tokens, and those tokens are billed.

For example: A founder asks for a pricing analysis across three plans. With reasoning turned on, the model takes longer and its answer costs more tokens than a quick reply.
