Solar Decide is Upstage's structured decision model family for typed choice/score/noul answers with calibrated probabilities via the System One (/v1/systemone) schema — not a chat LLM family. First public model solar-decide runs as a System One endpoint on Solar Mini 4. Peer of TypeSafe Jev as a decision model: own Upstage lab family; do not attach under system-one or solar-mini.
