Microsoft releases decision-focused AI model for quality checking other AI outputs

Microsoft introduced a specialized model called Microsoft-Decision-1 this month via OpenRouter. The model provides probability scores for yes/no questions about specific facts rather than making complex judgments. Developers at DEV Community tested it as a quality checker for AI tool calls, finding it unreliable for subjective questions but consistent for factual verification. They implemented a system where code first identifies facts, then asks the model clear-cut questions about those facts. The final version achieved their accuracy targets by focusing only on factual verification and rejecting judgment calls.
