Perplexity Decider V1.1 27B
Perplexity's 27B decision model, a newer checkpoint of Decider V1 that reads a state and returns typed, probabilistic answers to choice, score and yes/no questions.
Perplexity's Decider V1.1 27B is an open-weight decision model. It reads a piece of text and answers typed questions about it, such as a choice between labels, a yes or no, or a score on a scale, with a probability for every option instead of written text. It runs entirely on your own hardware through Ollama: no API key and no per-use fees.

Answered by Decider V1.1 27B via OpenRouter. A decision model returns probabilities, not prose, so each card shows how sure it was about every option. The same four questions run against every Decision model in the catalog.
