AI on demand: Mapika/decider-31b

Overview

System One decision models such as Mapika/decider-31b assess text and return structured answers and probabilities in a single forward pass.

They support three question types:

• Choice
  • Selects the single best option (or returns a probability distribution) from a fixed set of 2 to 255 declared options.

• Noul (Yes/No)
  • Returns a boolean probability distribution for a binary question.

• Score
  • Assigns a numeric value along a defined ordered scale (typically 2 to 10 levels) to represent a grading rubric or rating.

These models suit classification, routing, and decision support. They do not generate conversational answers or explanations, and their predictions can be wrong. Reported probabilities require evaluation on representative data before using them for consequential automation.

Our Mapika/decider-31b implementation has a multilingual checkpoint with a fixed 40960-token input limit.
