What it asks Jev

These question sets are lifted from this project's source exactly as written.

import { experimental_evaluate as evaluate } from 'ai';

const { answers } = await evaluate({
  model: 'typesafe-ai/jev',
  state,
  questions: {
    binary: { type: 'boolean', instructions: 'Is the state about a refund?' },
    rating: { type: 'score', instructions: 'question',
      criteria: ['level', 'low', 'medium'] },
  },
});
