❓ Frequently Asked Questions
What is Microsoft AutoGen?
Microsoft AutoGen is an open-source framework for creating AI-agent applications, including systems in which multiple agents exchange messages, use tools, execute workflows, and involve human input.
Is Microsoft AutoGen free and open source?
Yes. AutoGen's source code is publicly available on GitHub under the MIT License. Using it may still incur charges from external model APIs, cloud services, or infrastructure.
What programming languages does AutoGen support?
The current official documentation provides Python and .NET APIs. Capabilities and package maturity can differ between those implementations, so developers should consult the relevant API documentation.
What is the difference between AutoGen Core, AgentChat, and AutoGen Studio?
Core is the event-driven foundation for scalable agent systems. AgentChat is a higher-level API for common conversational and multi-agent patterns. Studio is a low-code interface for prototyping and inspecting agent workflows.
Is Microsoft AutoGen still active?
Yes. The official documentation and GitHub organization remain available, and Microsoft has published the redesigned AutoGen 0.4 release and migration guidance. This record therefore classifies the project as active.
