Solar Decide API pricing

upstage/solar-decide

Structured decisions. Solar Decide by Upstage, routed through INFRO on a Upstage account you connect — alongside every other provider you run. Upstage bills you for it directly, on that account and at your own rate. INFRO adds routing, failover, request logs, cost attribution and policy around it, and takes no part of what you pay Upstage.

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 Upstage connection or an OpenRouter one: your INFRO gateway key, spend limits checked before the call, and an estimated cost on every response.
