About AutoGen

AutoGen is a tool that is Microsoft's open-source framework for building applications where multiple AI agents converse, use tools and solve tasks together or with humans in the loop. It is built for researchers and developers building agent systems. The result is a focused workflow that saves time compared with doing the same work manually, while keeping the user in control of the final output and quality.
