Solar Decide

Upstage's Solar Decide joins the Decisions family: send state and typed questions, get structured answers instead of chat text, with a 524,288-token context window at $0.05 per million input tokens.

upstage/solar-decide is Upstage's structured decision model, served as a System One endpoint on Solar Mini 4. Send state and typed questions (noul / choice / score) to POST /api/v1/decisions and get answers back rather than generated chat text. It has a 524,288-token context window, so the state can carry a long document or a full ticket thread.

  • Terminal — anyr decision --model upstage/solar-decide (Decisions app).
  • App code — plain fetch to /api/v1/decisions, see the example below.

Solar Decide is **BYOK-only**, reached through OpenRouter. Add an OpenRouter key under Dashboard → BYOK — AnyRouter charges nothing for a BYOK route, and OpenRouter lists the model at $0.05 per million input tokens and $0 per million output tokens. AnyRouter has no direct Upstage route for it yet.

        },
      },
    },
  }),
})
console.log(await res.json())
One request, one choice question.
