JevModel is an independent, bilingual guide and browser workbench for TypeSafe's Jev decision model, aimed at developers and product teams who need a judgment their code can act on. Instead of free-form prose, Jev returns a typed answer: one choice from a set you define, a score on a scale, or the probability that a statement is true. The Jev Workbench ships ten editable workflow presets covering support routing, lead scoring, agent action gating, incident triage, release readiness and more; edit the state and questions and run a real decision in the browser. Each account gets five free runs per UTC day plus a one-time 100K token grant. Thirty-plus guides cover the API, question types, access paths, comparisons with LLM prompts and rules engines, and evaluation.
