Choose one question or three different questions about the same context. Try a real scenario, edit the inputs, then inspect each typed answer.
Explore one answer type at a time. Each run uses one daily attempt.
Run a case to see one typed answer per question. Choice picks an option, Score places it on a scale, and Probability returns a value from 0 to 1.
The form above puts your text under state.input. Try one question or three named questions against that same state. Look for each result under answers.<question_id>.
The request defines the questions and answer formats. The response returns a separate result for each question. These are the fields you can inspect in the request preview and model response above.

One answer is not fed into another. This Playground caps a run at three questions and counts it as one daily attempt. A correctly shaped answer can still be wrong, so test representative cases before automating an action.

TypeSafe has its own endpoint, model IDs, and API keys. Its quickstart uses jev-latest and shows how to ask multiple questions in one request.
// Run on your server. Keep the API key out of browser code.
const apiKey = process.env.OPENROUTER_API_KEY;
if (!apiKey) throw new Error("Set OPENROUTER_API_KEY");
const response = await fetch("https://openrouter.ai/api/alpha/decisions", {

console.log(answers.team.choice, answers.urgency.score, answers.escalate.noul);Choose the type that matches the decision your code needs to make. In the multiple-question cases above, one request returns a separate answer for each question ID.

The score is a probability-weighted position and may fall between the levels you defined.
Read a value from 0 (no) to 1 (yes). Noul has no separate confidence field.
TypeSafe accepts text, JSON objects, or arrays of text as state; this simple form wraps your text under input. Jev does not accept images, audio, or video. Typed output keeps the format predictable, but an individual judgment can still be wrong. Test on your own examples and define when your code should ask for review.
