About this model

Jev 1.13 is TypeSafe's System One structured decision model designed for fast, predictable decision-making inside software applications. Rather than generating free-form text, Jev evaluates application state against explicitly defined questions and returns typed structured decisions with probabilities and confidence values. It supports Choice for classification among predefined options, Score for ordered numerical assessments, and Noul for probability-like binary decisions. The model is optimized for routing, classification, moderation-style decision gates, workflow automation, agent control, risk assessment, and other applications where deterministic output structure and calibrated uncertainty are more useful than generated prose.
