AutoGen Reviews, Pricing, Features & Alternatives (2026)

Microsoft AutoGen is an open-source framework developed by Microsoft Research for building AI applications using multiple collaborating agents. Instead of relying on a single AI model, AutoGen allows developers to create systems where several agents communicate with each other to solve tasks, making it more suitable for complex workflows.

The framework focuses on “multi-agent conversation,” where agents can exchange messages, use tools, execute code, and even involve human input. This approach enables more advanced capabilities such as task delegation, iterative reasoning, and autonomous problem-solving.

AutoGen is commonly used in AI engineering for building agentic systems like autonomous assistants, coding agents, research tools, and workflow automation pipelines. It is positioned as a foundational framework in the growing ecosystem of agent-based AI development, alongside tools like LangChain, CrewAI, and newer Microsoft frameworks.
