Reasoning models covers models trained with RL to think step-by-step before answering (test-time compute).
In brief
Reasoning models, in brief.
What it isReasoning models covers models trained with RL to think step-by-step before answering (test-time compute).
Where it sitsOne of 24 categories in the Models layer. Models are the trained systems that do the work: language models, and models for speech, images, video, code, translation and forecasting. This layer covers both closed models reached through an API and open models you can download.
What we track26 products, including Apriel Thinker, Claude (extended thinking), Command A Reasoning, DeepScaleR and DeepSeek-R1 / V-series thinking mode.
