Microsoft’s annual developer conference- Build 2025 was held yesterday at which the company shared about building the open agentic web, where AI agents make decisions and perform tasks on behalf of users or organizations. Microsoft Chairman and CEO Satya Nadella made some big announcements at this year’s Microsoft Build.
Today, at Build we showed you how we are building the open agentic web. It is reshaping every layer of the stack, and our goal is to help every dev build apps and agents that empower people and orgs everywhere. Here are 5 big things we announced today:

Here are some of the biggest announcements of Build 2025
GitHub Copilot Coding agent
GitHub Copilot is evolving from an in-editor assistant to an agentic AI partner with a first-of-its-kind asynchronous coding agent integrated into the GitHub platform. You can assign the agent issues like bug fixes, new features, or ongoing code maintenance, and it will complete these tasks autonomously.
Copilot Tuning
With Copilot Tuning, customers can use their company data, workflows, and processes to train models and create agents in a simple, low-code way. These agents perform highly accurate, domain-specific tasks securely from within the Microsoft 365 service boundary. For example, a law firm can create an agent that generates documents aligned with its organization’s expertise and style.
Upgrades to Azure AI Foundry
Azure AI Foundry is a unified platform for developers to design, customize,e and manage AI applications and agents. With Azure AI Foundry models, Microsoft is bringing Grok 3 and Grok 3 mini models from xAI to its ecosystem. New tools like Model Leaderboard are introduced across different categories and tasks, and the Model Router is designed to select an optimal model for a specific query or task in real time.
The company has announced new features in Azure AI Foundry Observability for built-in observability into metrics for performance, quality, cost, and safety, all incorporated alongside detailed tracing in a streamlined dashboard. With Microsoft Entra Agent ID, now in preview, developers create agents in Microsoft Copilot Studio or Azure AI Foundry and automatically assign unique identities to an Entra directory.
Microsoft has added support for Agentic retrieval in Azure AI Search, Foundry Agent Service, integration with Copilot Studio, and more.
NLWeb
Microsoft is introducing NLWeb, which is believed to play a similar role to HTML for the agentic web. NLWeb makes it easy for websites to provide a conversational interface for their users with the model of their choice and their data, allowing users to interact directly with web content in a rich, semantic manner. Every NLWeb endpoint is also an MCP server, so websites can make their content easily discoverable and accessible to AI agents if they choose.
Microsoft Discovery
It is an extensible platform built to empower researchers to transform the entire discovery process with agentic AI, helping research and development departments across various industries accelerate the time to market for new products and accelerate and expand the end-to-end discovery process for all scientists.
