| Summary | Semantic Kernel is an open-source SDK from Microsoft that helps developers build AI agents and orchestrate large language models with native code, plugins, and APIs across C#, Python, and Java. It serves as a middleware/orchestration layer connecting prompts, services, and functions in enterprise and production environments. | AI SDK UI is Vercel's open-source frontend toolkit providing framework-agnostic hooks (useChat, useCompletion, useObject) for React, Vue, Svelte, Solid, and Angular that handle streaming chat state and generative UI interactions. It is the UI layer of the broader Vercel AI SDK, enabling developers to build AI-powered chat and completion interfaces without managing low-level streaming logic. |
