Upstage Solar Decide is a decision model served as a System One endpoint on Solar Mini 4: send application state and typed questions (noul / choice / score) and get structured answers back — not generated chat text. It has a 524,288-token context window. Call POST /api/v1/decisions (POST /api/v1/systemone is the same handler).
Solar Mini 4 is Upstage's small, fast tier in the Solar 4 generation: a text-only model with a 524,288-token context window at roughly $0.05 / $0.20 per million input / output tokens. It is the cheap sibling of upstage/solar-pro4, not a packaging of it, so it gets its own listing row.
Solar Pro 4 is Upstage's cost-efficient large language model with a 524K context window, built for long-horizon tasks and agentic workflows.
