AutoGen

AutoGen simplifies the creation of AI systems where agents coordinate to tackle problems beyond what a single model can handle. Agents exchange messages, call tools, and make decisions collectively, enabling patterns like code review loops, hierarchical problem-solving, and human-in-the-loop workflows.

Highlights

• Multi-agent orchestration with flexible message-based communication between agents
• Three API layers: Core API for fine-grained control, AgentChat for rapid prototyping, Extensions for custom LLM integration
• Includes AutoGen Studio, a no-code visual interface for building agent workflows without writing Python
• Support for tool use including web browsing, code execution, and custom MCP servers
• Works with Python and .NET for cross-platform development

Developers use AutoGen to prototype multi-agent systems quickly, then extend them with custom logic. Free and open-source under permissive licenses, making it accessible for research, startups, and enterprise teams building next-generation AI applications.
