Solar Decide
Upstage's structured decision model, a System One endpoint on Solar Mini 4. Returns a choice, a score or a yes/no answer with a probability read from the model, in one forward pass, on the same /v1/systemone schema as Jev.
In beta on the Upstage Console (released 22 September 2026 per the console; OpenRouter lists it from 28 September on its Decisions API). $0.10 per million input tokens, output free, cached input $0.10; OpenRouter shows a 50% promotion to $0.05. A 512K-token context lets a whole document be the state, and Upstage highlights its Korean understanding. Solar Mini 4 is a 35B mixture of experts with 3B active parameters (Upstage Console). No accuracy numbers are published.
