Comparison Preset
Neither AutoGen nor Semantic Kernel is a clear winner for an enterprise deployment, as both present significant, distinct risks. Semantic Kernel's MIT license, v1.0+ release, and 205 dependent repos suggest maturity, but its active CRITICAL vulnerability is a major security concern that must be addressed. Conversely, AutoGen has no known vulnerabilities, which is a significant advantage for risk management. However, its CC-BY-4.0 license requires legal review for attribution compliance, and its low commit frequency raises concerns about long-term maintainability. A decision requires weighing Semantic Kernel's immediate security flaw against AutoGen's potential licensing and maintenance hurdles.
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 building AI agents and applications, ranging from no-code prototyping to scalable, event-driven multi-agent systems. It supports conversational applications, complex workflows, and features like secure code execution and distributed agents.
Semantic Kernel is a lightweight, open-source development kit for building AI agents and integrating current AI models. It acts as efficient middleware, connecting AI prompts with existing APIs to automate business processes and deliver enterprise-grade solutions. Its modular design supports extensibility and future-proof AI integration.
