Solar DecideUpstage · Sep 28, 2026

Solar Decide does not write text. You describe a situation, ask typed questions, and it answers with one pick from your options, a number, or a yes or no, each with a probability. A whole document of about 500 pages can serve as the situation, and the Korean it understands is strong, which helps in routing, sorting and policy checks. Solar Decide Flash is the faster variant.
