AI SDK

The AI SDK is a free, open-source TypeScript toolkit designed to help developers build AI-powered applications. It provides a unified interface for integrating large language models (LLMs) across different providers, eliminating the complexity of managing multiple provider APIs and handling different response formats.

No. While the AI SDK is maintained by Vercel, you don't need to use Vercel to deploy it. It's free, open-source software that can be deployed anywhere.

Yes, the AI SDK is completely free and open-source.

The AI SDK consists of three main components: AI SDK Core, used for backend operations with Node.js, Deno, Bun, and other runtime environments, which handles server-side AI operations with functions like generateText for creating text responses, streamText for streaming responses, generateObject for structured data generation, and streamObject for streaming structured data; AI SDK UI, a set of framework-agnostic hooks and components for building interactive interfaces and linking a front end to an AI SDK backend; and AI SDK RSC, a framework for building with React Server Components.

The AI SDK is framework-agnostic and works with React, Next.js, Vue, Nuxt, SvelteKit, Svelte, and Node.js.

The AI SDK works with Large Language Models (LLMs) and Embedding Models. LLMs are the main models you interact with (like ChatGPT, Claude, or Perplexity), while embedding models help with tasks like semantic search and data retrieval.

Yes. One of the main features of the AI SDK is its unified provider API, which allows you to switch between AI providers by changing a single line of code. This eliminates the need to rewrite code when trying different models or providers.

The AI SDK can help you build RAG (Retrieval-Augmented Generation) agents, multi-modal agents that process images and PDFs, chatbots, and generative UI applications.

Yes. In addition to text generation, the AI SDK Core provides functions like `generateObject` and `streamObject` to generate structured JSON data, allowing you to constrain model outputs to a specific schema.

Yes. The AI SDK enables streaming AI responses so users don't have to wait for complete responses before seeing output.

The AI SDK has a dedicated troubleshooting section designed to help you quickly identify and resolve common issues encountered during development.
