About this model

Solar Decide Flash is Upstage's fast, low-latency structured decision model built on Solar Mini 4 and optimized for high-throughput classification, routing, scoring, and automated decision-making. Unlike conventional generative language models, it processes text or structured JSON state and answers predefined questions with structured decisions and associated probabilities. It supports Choice decisions for selecting among options, Score decisions for evaluating ordered scales, and Noul decisions for estimating yes/no probabilities. The model uses a single-forward-pass decision architecture, supports a 524,288-token context window, and is designed for customer-support routing, intent classification, policy evaluation, content moderation, risk assessment, and agent orchestration. It is served through the System One decision API.
