AutoGen

MAINTENANCE MODE. AutoGen is Microsoft's open-source framework for building multi-agent AI applications, where agents converse and collaborate to solve tasks. Supports tool use, human-in-the-loop, and a layered architecture (Core, AgentChat, Extensions). Microsoft has placed AutoGen in maintenance mode: its README states the project will receive no new features and is community managed, and directs new users to Microsoft Agent Framework.
