What is AutoGen?

Microsoft no longer provides bug fixes, security fixes, new features or support, and it advises against production use.

AutoGen needs Python 3.10 or later. It ships AgentChat and Core APIs, extensions for model clients and tools such as MCP, and AutoGen Studio, a no-code GUI for prototyping multi-agent workflows.
