decisionsVision

Decider V1.1 27B is a new checkpoint of Perplexity's decision model, succeeding [Decider V1 27B](/perplexity/pplx-decider-v1-27b) 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`), 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. A request can carry up to 128 questions about the same content.
