Microsoft Copilot's Post-Build 2025 Expansion: Key Updates and Future Roadmap
Microsoft's Build 2025 conference changed everything for Copilot. What started as a simple AI assistant is now becoming a full collaboration platform for developers, businesses, and regular users. With new features like multi-agent systems, Copilot Tuning, and better Azure AI connections, Microsoft is pushing hard toward an AI-first workplace.
Here's what's new after Build 2025 and the trends everyone's talking about.
1. Copilot Tuning: Custom AI for Enterprises
What's New: Companies can now train Copilot using their own data and workflows without needing a team of data scientists.
Example: A law firm can teach Copilot to write legal documents in their specific style using old case files.
When: Starting in June 2025 for customers with 5,000+ Microsoft 365 Copilot licenses.
