Microsoft just made a ton of new AI announcements across GitHub, Copilot, Azure AI Foundry, Windows, and more.

Here’s everything important announced live from Microsoft Build 2025:

1. GitHub Copilot is going from an in-editor assistant to a fully autonomous coding agent!

It works asynchronously to add features, fix bugs, extend tests, refactor code, and improve documentation

Plus, Microsoft is open-sourcing Copilot Chat in VS Code

2. Copilot Tuning: A new, low-code capability in Copilot Studio to train models and create agents using company data

3. All agents built can now be integrated with Teams and Copilot

Users can chat with them, assign action items, and kick off new workflows by mentioning them in a chat or meeting

Plus, the enhanced Teams AI library now supports MCP and A2A protocols.

4. Azure AI Foundry updated with new models including Grok 3, Flux Pro 1.1, and Sora (coming soon)

Also includes new model router, multi-agent workflows, observability features, and Foundry local for creating localized AI apps on Windows and Mac

5. Windows enhanced with new AI-focused capabilities, including:

—Windows AI Foundry with Windows ML, Foundry Local, ready-to-use AI APIs for vision and language tasks
—Native MCP support
—App Actions
—Open-sourced Windows Subsystem for Linux

6. NLWeb: A new open protocol to make any website an agentic application, capable of supporting AI search

This will allow users to query the contents of the site by using natural language, just like with an AI assistant or Copilot

7. Microsoft Discovery: A new agentic platform that enables researchers to collaborate with specialized AI agents to drive scientific research and outcomes

The agents generate ideas, simulate results, and learn over time
