Microsoft pairs Scout agents with its first in-house reasoning model

Microsoft used Build to show a more independent AI stack: Scout, an always-on assistant built around OpenClaw-style agent behavior, and MAI-Thinking-1, the company's first internally developed reasoning model. Axios reports that MAI-Thinking-1 has 35 billion active parameters and is meant to compete on cost and controlled training rather than frontier-scale supremacy; Microsoft said it was not distilled from other models and was trained on commercially licensed data. TechCrunch reports that Scout will work across Microsoft 365, the desktop, and the browser with persistent user-specific skills, audit trails, and policy conformance checks. Together, the launches matter because Microsoft is no longer only distributing OpenAI capabilities through Copilot. It is assembling its own models, agents, devices, and governance layer around enterprise workflows.
