By now, most AI practitioners are likely familiar with LangChain or have had some experience using it. But is there something new and even more promising on the horizon?

Introducing Semantic Kernel

Microsoft’s Semantic Kernel presents a concept quite akin to LangChain. It stands as a sophisticated Software Development Kit (SDK) that integrates Large Language Models (LLMs) such as OpenAI, Azure OpenAI, and Hugging Face with conventional programming languages like C#, Python, and Java. The real magic happens when you harness Semantic Kernel’s potential to define plugins that can be intricately connected with just a few lines of code.

What makes Semantic Kernel special, however, is its ability to automatically orchestrate plugins with AI. With Semantic Kernel planners, you can ask an LLM to generate a plan that achieves a user’s unique goal. Afterwards, Semantic Kernel will execute the plan for the user.

Kernel and Plugins

Within this framework, the term “kernel” designates a processing engine instance responsible for fulfilling a user’s specific request by assembling an array of plugins.

In the above example, the kernel fuses together two plugins, each serving different functions. Similar to the idea of UNIX kernel but this…
