About AutoGen
AutoGen is an open-source programming framework by Microsoft for building multi-agent AI applications. It enables agents to converse with each other and with humans to autonomously solve complex tasks. The framework supports multiple LLM providers (e.g., OpenAI GPT-4o), includes a no-code GUI called AutoGen Studio, and offers cross-runtime interoperability via A2A and MCP. Note: AutoGen is currently in maintenance mode; new users are directed to Microsoft Agent Framework (MAF) which provides stable APIs and long-term support.
