Microsoft Build 2025: The age of AI agents and building the open agentic web

We've entered the era of AI agents. Thanks to groundbreaking advancements in reasoning and memory, AI models are now more capable and efficient. We envision the internet evolving into an open agentic web, where AI agents make decisions and perform tasks on behalf of users or organizations.

At Microsoft Build 2025, we're showing the steps we're taking to make this vision a reality through our platforms, products and infrastructure, enabling developers and organizations to invent the next big thing. Key announcements include:

Reimagining the software development lifecycle with AI

• GitHub Copilot coding agent and new updates to GitHub Models: GitHub Copilot is evolving to an agentic AI partner with an asynchronous coding agent. GitHub Models gets prompt management, lightweight evaluations, and enterprise controls. Microsoft is also open-sourcing GitHub Copilot Chat in VS Code, reinforcing commitment to open, collaborative, AI-powered software development.
• Introducing Windows AI Foundry: A unified platform for the AI developer lifecycle across training and inference on Windows, offering simple model APIs and supporting open source LLMs via Foundry Local or proprietary models.
• Azure AI Foundry Models and new tools for model evaluation: Adds Grok 3 and Grok 3 mini models from xAI. Developers can choose from over 1,900 models and manage data integration, customization, and governance. New tools include the Model Leaderboard and Model Router.

Making AI agents more capable and secure

• General availability of Azure AI Foundry Agent Service: Empowers professional developers to orchestrate multiple agents for complex tasks, integrating Semantic Kernel and AutoGen. Azure AI Foundry Observability provides built-in metrics for performance, quality, cost, and safety.
• Discover, protect and govern in Azure AI Foundry: Microsoft Entra Agent ID (preview) assigns unique identities to agents for secure management and avoiding "agent sprawl". Integrates with Purview data security and compliance controls.
• Introducing Microsoft 365 Copilot Tuning and multi-agent orchestration: Copilot Tuning allows customers to train models and create agents with their own company data and workflows in a low-code way, enabling accurate, domain-specific tasks securely within Microsoft 365. New multi-agent orchestration in Copilot Studio connects agents to tackle complex tasks.

Supporting the open agentic web

• Supporting Model Context Protocol (MCP): Microsoft provides broad first-party support for MCP across its agent platforms. Microsoft and GitHub joined the MCP Steering Committee and announced an updated authorization specification and the design of an MCP server registry service to advance secure, at-scale adoption of the open protocol.
• A new open project called NLWeb: Introducing NLWeb, designed to play a role similar to HTML for the agentic web, making it easy for websites to provide a conversational interface and make content discoverable to AI agents.

Accelerating scientific discovery with AI

• Introducing Microsoft Discovery: An extensible platform built to empower researchers to transform the entire discovery process with agentic AI, accelerating time to market for new products and expanding the end-to-end discovery process for all scientists.

These announcements highlight Microsoft's focus on AI agents, developer tools, enterprise-grade capabilities, open standards, and accelerating scientific discovery, all driving the future of the open agentic web.
