Microsoft AutoGen remains relevant in 2026 with In 2026, Microsoft announced a major strategic shift: AutoGen and Semantic Kernel will enter maintenance mode, with active development consolidating into the new Microsoft Agent Framework. This production-ready framework merges AutoGen's simple multi-agent abstractions with Semantic Kernel's enterprise features including session-based state management, filters, telemetry, and extensive model support. Existing AutoGen users are encouraged to plan migration to the Microsoft Agent Framework for continued access to new features and long-term support. AutoGen will continue to receive critical bug fixes and security patches during its maintenance phase, but no new feature development is planned. The v0.4 asynchronous architecture remains the final major release, and the AutoGen community is being directed toward the Microsoft Agent Framework GitHub repository for future contributions and roadmap discussions.. The multi-agent builders market continues to grow, making it a solid investment for professionals.
The free tier covers basic needs but upgrading unlocks advanced features like Full AutoGen framework under MIT license with no usage limits. Most professionals will need the paid version.
