Quick answer

What is Jev Score?

Score turns an input and rubric into a numeric signal. Define the scale, anchors, and interpretation yourself; do not present an uncalibrated score as certainty.

Example rubric

Input“Customer asks for an immediate refund after a duplicate charge.”

QuestionHow urgent is this ticket?

Scale0 = routine · 50 = needs review · 100 = immediate escalation

GuardrailStore the rubric with the score so downstream users know what it means.

Integration shape

const result = await experimental_evaluate({
  model: "typesafe-ai/jev",
  providerOptions: { typesafeai: { question: "How urgent is this ticket?", scale: { min: 0, max: 100 } } },
  input: ticketText
});
