AutoGen

✓

Microsoft's multi-agent conversation framework for complex AI workflows

AutoGen is Microsoft's open-source framework for building multi-agent AI systems. Version 0.4 (early 2025) introduced a major architectural redesign with an event-driven foundation, segmenting the framework into distinct components: AutoGen-Core, AgentChat, AutoGen-Extensions, and a rebuilt low-code AutoGen Studio. It enables specialized agents to collaborate on complex tasks through async conversations with human-in-the-loop capabilities. Features superior scalability, observability, and cross-language support for Python and .NET.
