Microsoft Build 2025: Top 5 announcements highlights from the developer conference

Microsoft kicked off its annual Build developer conference 2025 in Seattle on Monday with a flurry of announcements spanning Windows, Office, Azure, and a heavy dose of AI integrations. The company focused less on interface tweaks and more on automation, large model support, and tools that rewrite how users interact with software. Here are five major highlights from the tech giants’ conference.

1. GitHub Copilot becomes a coding agent

Developers will no longer need to hold Copilot’s hand. Microsoft turned GitHub Copilot into a full coding agent. It now takes assigned tasks, like fixing bugs, adding new features, or handling code cleanup, and finishes them on its own. Developers can now assign issues and let Copilot do the heavy lifting without constant intervention.

2. Copilot can be trained on your company’s voice, tone, and more

Microsoft 365 Copilot can now learn how your team writes. The new tuning feature lets companies set their tone, writing style, and domain expertise, turning Copilot into a workplace-specific writing assistant. It’s meant to keep communications consistent and on-brand.

3. AI Multimodel Support for Devs

Azure Foundry now supports models from Grok, Mistral, Meta, and Hugging Face. Developers can spin up multi-agent workflows inside Copilot Studio, tie them to Azure AI Search, and manage them with Microsoft’s identity and security tools. The NFL already used Foundry to analyze player data during its Combine.

4. NLWeb gives websites a voice

NLWeb is Microsoft’s new open standard that lets sites add natural-language interaction. It works like HTML, but instead of buttons and links, users can ask questions or make requests. Imagine typing “show me your refund policy” on any site and getting a straight answer, fast. Site owners can host their own AI agent using whatever model they want, no cloud middleman required.

5. Microsoft Discovery speeds up scientific research

Discovery combines agents, simulations, and data models to help researchers test ideas faster. Microsoft shared an example: a new coolant candidate that avoids harmful forever chemicals. Discovery can propose materials, simulate reactions, and surface patterns across datasets in ways that traditional analysis can’t match in speed or scale.

Microsoft Build 2025 clearly signaled where the tech giant is headed in the future. Developers and techies can expect less clicking, more asking. And if Microsoft gets its way, your next app might answer back.
