TheAI SDK is a TypeScript toolkit designed to help you build AI-powered applications using popular frameworks like Next.js, React, Svelte, Vue and runtimes like Node.js.

To learn more about how to use the AI SDK, check out ourAPI Reference andDocumentation.

You will need Node.js 18+ and pnpm installed on your local development machine.

npm install ai

TheAI SDK Core module provides a unified API to interact with model providers likeOpenAI,Anthropic,Google, and more.

You will then install the model provider of your choice.

npm install @ai-sdk/openai

import{generateText}from'ai';import{openai}from'@ai-sdk/openai';// Ensure OPENAI_API_KEY environment variable is setconst{ text}=awaitgenerateText({model:openai('gpt-4o'),system:'You are a friendly assistant!',prompt:'Why is the sky blue?',});console.log(text);

TheAI SDK UI module provides a set of hooks that help you build chatbots and generative user interfaces. These hooks are framework agnostic, so they can be used in Next.js, React, Svelte, Vue, and SolidJS.

'use client';import{useChat}from'ai/react';exportdefaultfunctionPage(){const{ messages, input, handleSubmit, handleInputChange, status}=useChat();return(<div>{messages.map(message=>(<divkey={message.id}><div>{message.role}</div><div>{message.content}</div></div>))}<formonSubmit={handleSubmit}><inputvalue={input}placeholder="Send a message..."onChange={handleInputChange}disabled={status!=='ready'}/></form></div>);}

import{streamText}from'ai';import{openai}from'@ai-sdk/openai';exportasyncfunctionPOST(req:Request){const{ messages}=awaitreq.json();constresult=streamText({model:openai('gpt-4o'),system:'You are a helpful assistant.',    messages,});returnresult.toDataStreamResponse();}

We've builttemplates that include AI SDK integrations for different use cases, providers, and frameworks. You can use these templates to get started with your AI-powered application.

The AI SDK community can be found onGitHub Discussions where you can ask questions, voice ideas, and share your projects with other people.
