Semantic Kernel

AI / LLM

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.

Pros & Cons

Pros

  • First-class C#, Python, and Java support
  • Designed to fit into existing enterprise apps
  • Backed and maintained by Microsoft
  • Clean plugin and function abstractions

Cons

  • Smaller ecosystem than Python-first frameworks
  • Roadmap is converging with Microsoft Agent Framework
  • Less suited to rapid Python prototyping
