Microsoft opened its Build 2026 keynote in San Francisco on June 2, unveiling a slate of developer announcements including new Microsoft AI models, Windows developer updates, and RTX Spark. The company announced a Copilot super app and a new reasoning model designed to accelerate coding and app development. Sarah Bird presented open-source observability and control tools to govern agents across the Microsoft Agent Framework and other stacks, focusing on safety, governance, and reliability for production agents. These changes push AI deeper into Windows and developer tooling, making it easier for apps to embed advanced models and for teams to monitor agent behavior in production.
