Decider V1.2

Decider V1.2 is a new 27B checkpoint of Perplexity's decision model, succeeding [Decider V1.1 27B](/perplexity/pplx-decider-v1.1-27b) with the same API contract. Instead of generating text, it reads content passed as `state` (text, JSON, or images) and returns typed, probabilistic answers to one or more named questions in a single request: the probability of yes for a yes/no question (`noul`), a probability for every option plus the most likely one (`choice`, up to 255 options), or a probability for every level of an ordered rubric plus the expected score (`score`).

It is built for classification, routing, moderation, and rubric grading where application code thresholds the returned numbers rather than parsing a chat reply. For a smaller, lower-cost option with the same contract, see [Decider Flash V1.2](/perplexity/pplx-decider-flash-v1.2).
