AutoGen is an open-source framework developed by Microsoft for building multi-agent AI systems and advanced LLM-powered applications.

It enables developers to create autonomous agents that can collaborate, converse, and solve problems together, or with human feedback integrated into the loop.

AutoGen provides abstractions for defining roles, tasks, and communication protocols between agents, allowing flexible setups from simple assistants to complex, multi-agent ecosystems.

It is designed for rapid prototyping as well as production deployment, with features like conversation orchestration, human-AI collaboration, and tool integration.
