Comparison Preset
Semantic Kernel is the more prudent choice for an enterprise environment due to its explicit commitment to v1.0+ API stability and non-breaking changes. Its MIT license presents lower legal friction than AutoGen's CC-BY-4.0, and the active commit frequency (4x/week) demonstrates strong, ongoing maintenance. However, teams must immediately address its two known vulnerabilities, one of which is rated critical. Despite this, AutoGen's lack of commits for over 100 days and pre-1.0 version status represent a greater long-term risk of project abandonment. Therefore, Semantic Kernel's manageable technical risks are preferable to the project viability risk posed by AutoGen's inactivity.
Overview
The bottom line ā 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 offers a modular architecture, enabling conversational agents, complex workflows, and integration with external services. The framework supports research and distributed applications.
Semantic Kernel is a lightweight, open-source SDK for building enterprise-grade AI agents and integrating AI models into C#, Python, or Java codebases. It acts as middleware, connecting AI models to existing APIs for business process automation, emphasizing modularity and future-proofing.
