At Microsoft Build 2025, the focus was on agentic AI, with developments in AI agents across GitHub, Azure AI Foundry, Windows, and Microsoft 365. Microsoft's vision is for an "agentic web," where intelligent systems autonomously perform tasks. Demonstrating this vision, GitHub Copilot is upgrading to an AI coding agent, while Azure AI Foundry now offers Grok 3 models from xAI, availing over 1,900 AI models to developers.
