What a decision model answers

  • Typed questions about the evidence you send: yes or no, one option of a closed set, a level on a rubric.
  • Probabilities on every answer, and a confidence for choice and score. No generated text.
  • Every INFRO decision feature runs on it: decision policies, rerank, classifier guardrails, the route classifier and evals.

OpenAI's or TypeSafe's request body, on your own Perplexity connection or an OpenRouter one: your INFRO gateway key, spend limits checked before the call, and an estimated cost on every response.
