Microsoft Launches Decision-1 Specialist Model; Google Extends Gemini Reasoning Controls

Microsoft unveiled Decision-1, a specialized decision-scoring model designed for rapid classification and routing tasks, while Google made advanced reasoning controls available to all Gemini app users. Microsoft's Decision-1, built by post-training Alibaba's open-weight Qwen3.5-9B, returns calibrated probability scores for discrete decisions—yes/no questions, multiple-choice selections, and rubric-based evaluations—in a single pass. The model is priced at $0.042 per million input tokens with free output tokens and is now available through Microsoft Foundry, with OpenRouter access coming soon.
