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 a cloud 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 reads up to 262K input tokens per request. It runs through OpenRouter using your own API key, from $0.02 per million input tokens.

Examples

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.
