AutoGen (Microsoft)

AutoGen is an open-source framework developed by Microsoft that enables developers to build applications using multiple conversational AI agents that can work together to accomplish complex tasks. The framework allows these agents to communicate with each other, execute code, and interact with external tools and services. It is designed for developers and researchers who want to create sophisticated automated workflows where different specialized agents collaborate to solve problems that would be difficult for a single agent to handle alone.

AutoGen is available as a free and open-source project, which means developers can use it without licensing costs and modify it according to their needs. A practical use case would be building a data analysis system where one agent retrieves information from databases, another agent writes and executes Python code to process that data, and a third agent summarizes the findings in natural language. This collaborative approach allows each agent to focus on its specific capability while contributing to a larger automated workflow.
