Reasoning models

282 in the catalogue today. Every one with what it costs, who sells it and where it stands. 282 in all, a hundred to a page; this is page 1 of 3.

Models that plan before they answer, spending extra tokens on working the problem through. They win on mathematics, hard code and anything with several steps, and they are measured on boards like GPQA, AIME and ARC-AGI. The catch is what the thinking costs: reasoning is billed as output tokens, so the same model can cost several times more per answer at a high effort than a low one, and for a question that needed one turn you have paid for a monologue.
