# Microsoft-Decision-1

> Microsoft-Decision-1 is a small Microsoft model built for fast decisions: yes/no, multiple-choice and rating questions, plus rubric-based grading of AI responses and agent actions. Send application state and typed questions (noul / choice / score) and get back a calibrated probability for each fixed answer option, not generated chat text. It has a 32,768-token context window. Call POST /api/v1/decisions (POST /api/v1/systemone is the same handler).
