Microsoft Build 2025 focused heavily on AI-driven development, multi‑agent architectures,
Copilot enhancements, and advances in Azure, Windows AI, Fabric, and developer tooling.
These sessions showcased both conceptual and deep‑dive technical content across real enterprise and developer scenarios.
1. Multi‑Agent AI Systems & Copilot Studio Enhancements
A central theme of Day 2 was the introduction of powerful improvements to Copilot Studio, enabling developers to build
sophisticated multi‑agent AI systems, integrate external models, and orchestrate end‑to‑end workflows.
These systems combine structured agent coordination, model routing, and domain‑specific knowledge. [1](https://www.hubsite365.com/en-ww/crm-pages/microsoft-build-2025-day-2-keynote-de0629ff-7470-4af8-b70a-5b8371b5c036.htm)
