AutoGen — Agent Frameworks Platform
Agent FrameworksLayer 3Open SourceWhat is AutoGen?
AutoGen is an open-source framework created by Microsoft Research that enables developers to build sophisticated multi-agent AI systems where multiple AI agents and humans collaborate toward shared goals. The framework stands out for its message orchestration layer that maintains focused, traceable, and goal-driven conversations between agents. AutoGen simplifies the development of complex agentic workflows by allowing developers to define agents in just a few lines of Python, specifying their name, role, and LLM backend, then immediately connecting them to other agents or external APIs.
The framework provides built-in capabilities for memory, reasoning, and communication, enabling agents to not only generate text but also execute code, call APIs, and query databases. AutoGen has demonstrated significant productivity improvements, with some teams reporting functional prototypes completed 3× faster than manual workflows. The framework has evolved into the Microsoft Agent Framework, combining AutoGen's multi-agent orchestration with Semantic Kernel's AI capabilities.
While AutoGen excels at complex multi-agent orchestration, it can be overly complex for simple workflows that could be achieved with lighter-weight tools. Users have identified challenges with scaling applications due to limited support for dynamic workflows and debugging tools, highlighting the need for stronger observability and more flexible collaboration patterns. As AutoGen transitions to maintenance mode with only bug fixes, Microsoft encourages migration to the new unified Agent Framework.
