The AI SDK is a provider-agnostic TypeScript toolkit designed to help you build AI-powered applications and agents using popular UI frameworks like Next.js, React, Svelte, Vue, Angular, and runtimes like Node.js.
AI SDK by Vercel - build apps like ChatGPT, Claude, Gemini, and more with a single interface for any model using the Vercel AI Gateway or go direct to OpenAI, Anthropic, Google, or any other model provider. (with updated dependencies)
By default, the AI SDK uses the Vercel AI Gateway to give you access to all major providers out of the box. Just pass a model string for any supported model:
const result = await generateText({
model: 'anthropic/claude-opus-5.5', // or 'openai/gpt-6-astra', 'google/gemini-3.8-flash', etc.
prompt: 'Hello!',
});
You can also connect to providers directly using their SDK packages:
import { anthropic } from '@ai-sdk/anthropic';
const result = await generateText({
model: anthropic('claude-opus-5-5'), // or openai('gpt-6-astra'), google('gemini-3.8-flash'), etc.
prompt: 'Hello!',
});
Usage
Generating Text
import { generateText } from 'ai';
const { text } = await generateText({
model: 'openai/gpt-6-astra', // use Vercel AI Gateway
prompt: 'What is an agent?',
});
import { ToolLoopAgent } from 'ai';
const sandboxAgent = new ToolLoopAgent({
model: 'openai/gpt-6-astra',
system: 'You are an agent with access to a shell environment.',
tools: {
shell: openai.tools.localShell({
execute: async ({ action }) => {
const [cmd, ...args] = action.command;
const sandbox = await getSandbox(); // Vercel Sandbox
const command = await sandbox.runCommand({ cmd, args });
return { output: await command.stdout() };
},
}),
},
});
UI Integration
The AI 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, and Vue.
You need to install the package for your framework, e.g.:
npm install @ai-sdk/react
Agent @/agent/image-generation-agent.ts
import { openai } from '@ai-sdk/openai';
import { ToolLoopAgent, InferAgentUIMessage } from 'ai';
export const imageGenerationAgent = new ToolLoopAgent({
model: 'openai/gpt-6-astra',
tools: {
generateImage: openai.tools.imageGeneration({
partialImages: 3,
}),
},
});
export type ImageGenerationAgentMessage = InferAgentUIMessage<
typeof imageGenerationAgent
>;
We've built templates 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.
