What is AutoGen?
AutoGen is Microsoft Research’s framework for building multi-agent systems where AI agents have conversations to solve problems. Agents can discuss, delegate, execute code, and collaborate—similar to humans working together.
In 2026, AutoGen became part of the broader Microsoft Agent Framework, integrating with Semantic Kernel for enterprise features like session management, telemetry, and middleware.
AutoGen’s standout feature is AutoGen Studio—a no-code GUI for building and testing multi-agent applications without writing Python code.
