Free deprecated educational framework that teaches multi-agent coordination fundamentals through minimal Agent and handoff abstractions.
Microsoft has been developing the Azure AI Agent Service and related agent tooling. AutoGen remains available as an open-source multi-agent framework. Check Microsoft's official documentation for the latest on how these projects relate.
Based on our testing, AutoGen excels at complex multi-agent orchestration with its event-driven architecture, cross-language support, and deep Azure integration. It has a steeper learning curve than CrewAI but offers more flexibility for advanced use cases.
Yes, AutoGen is fully open-source under the MIT license. You can use it freely for commercial and non-commercial projects. Azure AI Foundry hosting is a separate paid service.
Use v0.4 for new projects. It features a completely redesigned async architecture, better observability, and improved extensibility. v0.2 is the legacy version.
AutoGen works with OpenAI, Azure OpenAI, Anthropic Claude, Google Gemini, Mistral, and local models via Ollama. It uses a model-agnostic interface for easy provider switching.
Consider Microsoft AutoGen carefully or explore alternatives. The free tier is a good place to start.
