True/false

Ask whether one stated proposition holds.

The API type is noul. Write one proposition with a clear meaning for both true and false. Do not include options or levels.

request
{
  "model": "ren-zero-2026-11-12",
  "type": "noul",
  "situation": "The customer wrote: Please cancel my subscription before it renews.",
  "question": "Does the customer explicitly request cancellation?",
  "threshold": 0.9
}

The response’s probability is the probability of true. probabilities has "true" and "false" keys. choice is the more probable answer, and confidence is the probability of that chosen answer.

A low probability can therefore accompany high confidence in false. Always read choice and action before acting; action: "act" does not mean the proposition is true.

For missing evidence, ask a separate question or escalate. False should not silently mean both “contradicted” and “unknown” when those require different actions.
