Jev Overview

Jev is TypeSafe AI's System One decision model for fast, machine-consumable judgments. It evaluates structured or unstructured application state against typed questions and returns bounded choices, ordinal scores, or yes-or-no probabilities with confidence in a parallel pass. Unlike generative language models, Jev does not produce free-form prose; it is designed for routing, classification, ranking, verification, guardrails, and real-time workflows where software must act on predictable outputs.
