Semantic Kernel
AI / LLMFreeVisit Site
An open-source SDK from Microsoft for integrating LLMs into applications, with a focus on enterprise-grade orchestration in C#, Python, and Java.
Overview
Semantic Kernel is the Microsoft approach to bringing LLM orchestration into existing enterprise codebases. Its appeal is pragmatic: first-class C# and Java support, plugin and function-calling abstractions, and a design meant to slot into apps that already exist rather than greenfield Python scripts. For .NET-heavy enterprises it is often the path of least resistance. The trade-off is a smaller ecosystem than the Python-first frameworks and a roadmap that tracks the broader Microsoft Agent Framework direction.
