Jev question types: Choice vs Score vs Noul

0

Choice, Score, and Noul answer different kinds of structured questions. Start with the decision your application needs: a routing label, an ordered assessment, or the estimated truth of a proposition. The table uses customer-support examples to explain the distinction.

Several questions can be evaluated against the same input. A billing ticket may still be urgent and require security review; routing, urgency, and escalation should therefore remain separate decisions. Validate the response schema before applying business rules and keep consequential actions behind an authorization boundary.

Prepared by Jev AI (jev-ai.pro), an independent playground and API platform for the Jev model developed by TypeSafe. This is a product-authored, AI-assisted implementation guide, not an independent benchmark. Examples and review policies are illustrative; no accuracy or latency measurements are claimed.

When to useSelect one label from a fixed, unordered set. Useful for routing tickets to billing, technical, or account queues.Evaluate an input against an ordered rubric. Useful for urgency levels with explicit definitions for each score.Estimate whether one clearly stated proposition is true. Useful for a separate escalation flag, independent of the routing label.
Example questionWhich team should handle this ticket? Choices: billing, technical, account. Include a fallback policy for unclear inputs.How urgent is this ticket? Define a rubric such as 1 = routine question, 2 = degraded function, 3 = service blocked. These are illustrative business definitions.Does this ticket describe an active account-security incident? Phrase one testable proposition rather than combining unrelated conditions.
Result to inspectchoice plus confidence and probabilities. Validate the label against the allowed choices; do not assume confidence equals the winning label probability.score plus confidence, legend, and probabilities. Interpret the score using the declared rubric, not as a universal measure of severity.noul: a value from 0 to 1 representing the model's estimated truth probability. It is an estimate, not verified evidence that an incident occurred.
Human review boundaryRoute unknown labels, malformed responses, and ambiguous cases to review. Keep refunds, deletions, and access changes behind separate authorization.Choose action thresholds using a labeled evaluation set and the cost of mistakes. A high urgency score can trigger review without directly executing an action.Use a review band between positive and negative decisions. Set thresholds with representative cases; do not copy a numeric threshold as a default safety guarantee.
Evaluation approachMeasure per-label precision and recall, plus confusion between queues. Include empty text, mixed intents, unseen topics, and instructions embedded in customer text.Measure disagreements against human rubric labels, especially large errors. Review whether two annotators interpret each level consistently.Measure false positives, false negatives, and calibration on labeled statements. Recheck results when input language or the incident definition changes.

A practical comparison of Jev Choice, Score, and Noul: select the right question type, interpret its output, evaluate errors, and decide when a person should review the result.
