Comparison Preset
Semantic Kernel is the appropriate choice for an enterprise environment due to its permissive MIT license, which poses a much lower risk than AutoGen's CC-BY-4.0. Its active development, commitment to V1.0+ API stability, and explicit focus on enterprise business processes provide the long-term maintainability stakeholders require. While Semantic Kernel has a known critical vulnerability, its active maintenance suggests it will be addressed, unlike AutoGen which has seen no commits in over 150 days. The combination of a suitable license and clear support signals makes Semantic Kernel the more defensible long-term decision.
Overview
The bottom line — what this framework is, who it's for, and when to walk away.
Bottom Line Up Front
AutoGen is a Python framework for developing AI agents and applications, ranging from no-code prototyping to scalable multi-agent systems. It supports conversational AI, dynamic workflows, and distributed agent collaboration through its modular, event-driven architecture.
Semantic Kernel is a lightweight, open-source development kit for building AI agents and integrating AI models into C#, Python, or Java codebases. It acts as middleware, translating AI model requests into calls to existing APIs and passing results back. Designed for enterprise use, it emphasizes flexibility, modularity, and future-proofing.
