Microsoft-Decision is Microsoft's family of decision-scoring models. Instead of generating text, a model reads a state (text or JSON) plus typed questions (noul for yes/no, choice, or score) and returns a probability for each fixed answer option. The first release, Microsoft-Decision-1 (2026-10-09), is a hosted model in Microsoft Foundry and on OpenRouter, post-trained by Microsoft from Qwen3.5-9B. Weights are not distributed. Not a chat model family.
