The AI SDK is an open-source TypeScript toolkit developed by Vercel (the Next.js team), designed to help developers efficiently build AI-powered applications and agents.
It supports major AI model providers such as OpenAI, Anthropic Claude, Hugging Face, and more through standardized APIs, making it easy to switch and integrate.
Requires Node.js 18+ environment, TypeScript/JavaScript development experience, and an API key for the respective AI service (e.g., OpenAI).
It abstracts underlying technical details, provides a unified API, prebuilt UI components, and rich examples, significantly reducing the amount of code and development time required to integrate AI features.
It is highly compatible with React, Next.js, Vue, Nuxt, SvelteKit, and other popular frontend and full-stack frameworks, with corresponding integration hooks.
It consists of AI SDK Core (providing core APIs for text generation, structured objects, tool calls, etc.) and AI SDK UI (focused on streaming UI integration and components).
Vercel AI Cloud is a platform that integrates AI development tools with cloud infrastructure, designed to help developers quickly build, deploy, and scale high-performance web and AI-native applications. By offering unified access to AI models, optimized deployment workflows, and a global performance network, it enables developers to focus on product innovation and streamline the end-to-end process from development to launch.
LiveKit AI is an open-source platform that integrates real-time audio/video with multimodal AI, helping developers quickly build production-grade intelligent applications with vision, hearing, and speech capabilities.
