Microsoft-Decision-1, our model for fast decision-making
Microsoft has introduced 'Microsoft-Decision-1', a specialized AI model designed for fast, structured decision-making tasks like routing and classification. The model is optimized for low latency and high performance, outperforming traditional LLMs in specific decision-scoring benchmarks.
Why it matters
This development signals a shift in AI utility from generative text to actionable, high-speed decision intelligence, which is critical for enterprise automation.
Decision models are quickly emerging as an important new category in AI. Unlike LLMs, which are designed to generate text or reason through complex problems, decision models are purpose-built to deliver structured outputs that software can immediately act on. And once you understand that capability—making decisions and classifying things at very low cost with high performance—all kinds of useful tasks get unlocked.
Today we’re introducing Microsoft-Decision-1 , our new model for fast decision-scoring, available in Microsoft Foundry and coming soon through OpenRouter. This model is designed for routing, classification, prioritization, verification, and workflow control, making it easier to incorporate decision intelligence into existing applications, agents, and workflows in a secure, trusted environment. Microsoft-Decision-1 delivers top performance in latency and quality on structured decision tasks to outperform both LLMs and other decision models.
