Microsoft Build 2025 announces the age of AI agents with 15M GitHub Copilot developers and major updates for M365 extensibility.

Microsoft Build 2025 announces the age of AI agents with 15M GitHub Copilot developers and major updates for M365 extensibility.

🤖 The Era of AI Agents Has Officially Begun

Microsoft’s Build conference kicked off on May 19 in Seattle — their big annual event where they share the latest news and tools for developers. And they made one thing crystal clear: we’re officially entering the age of AI agents.
With huge leaps in reasoning and memory, today’s AI models are smarter and more efficient than ever. We’re already seeing real-world examples of AI helping us tackle challenges in totally new ways.

These are Microsoft’s statements about the figures that define developers; I personally find them interesting.

  • 💻 15 million developers use GitHub Copilot, relying on agent mode and code review to streamline coding, testing, and deployment.
  • 🧠 Hundreds of thousands of customers are using Microsoft 365 Copilot to support research, brainstorming, and solution building.
  • 🏢 Over 230,000 organizations — including 90% of the Fortune 500 — have leveraged Copilot Studio to build AI agents and create automation flows.

🔧 Developers Are the Heart of This Transformation

For over 50 years, Microsoft has empowered developers with tools and platforms to bring their ideas to life. With AI-driven automation and integrated cloud services, developers are now driving the next digital revolution.


🚀 Highlights from Microsoft Build 2025

📘 The new Book of News is full of game-changing updates for #Microsoft365 and #Copilot — focused on making work smarter, more personalized, and proactive.

Here are the standout announcements from my perspective:


🔹 Microsoft 365 Copilot APIs — My absolute favorite!

🎯We’ve been waiting a long time for this — and now they’re live.
These APIs allow developers to embed Copilot experiences directly into their own apps and workflows. This is a major milestone in bringing AI assistance to custom business scenarios.

➡️ Explore the Copilot APIs


🔹 Copilot Tuning & Multi-Agent Orchestration

With Copilot Tuning, organizations can use their internal data, workflows, and processes to train models and build precise, domain-specific AI agents using a low-code approach.

Example: A law firm could train an agent to draft legal documents aligned with the firm’s style and knowledge base.

And now, with multi-agent orchestration in Copilot Studio, these agents can collaborate — combining skills to tackle more sophisticated, end-to-end processes.

🔹 Microsoft 365 Agents Toolkit

Formerly known as Teams Toolkit, this new Agents Toolkit brings a whole new developer experience for building and deploying intelligent agents.

It includes:

  • 🔧 A new Agents SDK
  • 🧠 The new version Teams AI Library
  • 🧩 Support for A2A and MCP in public preview

➡️ Check the documentation


🌐 What’s Next? A Web of Intelligent Agents

We’re heading toward a world where AI agents operate at personal, team, organizational, and enterprise levels.

This emerging vision? An open agentic web — where agents perform decisions and actions on behalf of users and businesses across platforms.

With the Microsoft 365 Copilot Wave 2 Spring Release now in general availability, it’s time to start experimenting and building.


🗣️ My Take as a Microsoft MVP

As a Microsoft MVP deeply involved in AI and Microsoft 365 technologies, I see these announcements as a real game changer. The ability to tailor AI agents to specific organizational needs, combined with the ease of embedding Copilot into custom workflows, opens unprecedented opportunities for innovation.

The developer-centric approach Microsoft is taking, especially with Copilot APIs and the Agents Toolkit, means that the power of AI is no longer confined to large enterprises — small and medium businesses, as well as individual developers, can now harness it to transform their daily work.

This shift will accelerate digital transformation across industries, making AI a true everyday ally rather than a distant futuristic concept. I’m incredibly excited to explore these tools and help others do the same.
