Agents League Hackathon
Microsoft
📌 About the Event
Agents League is a Microsoft AI developer challenge where people build AI agents and compete in an esports-style format. The focus is on live AI battles and community builds, so the goal is both learning and competition. Use agentic AI ideas to create practical, creative solutions. The challenge is designed to make AI agent development feel fast, fun, and game-like. Also connects with Microsoft’s broader push to teach AI skills at scale.
