AI SDK - OpenAI Provider

The OpenAI provider for the AI SDK contains language model support for the OpenAI chat and completion APIs and embedding model support for the OpenAI embeddings API.

Deploying to Vercel? With Vercel's AI Gateway you can access OpenAI (and hundreds of models from other providers) — no additional packages, API keys, or extra cost. Get started with AI Gateway.

Setup

The OpenAI provider is available in the @ai-sdk/openai module. You can install it with

npm i @ai-sdk/openai

Skill for Coding Agents

If you use coding agents such as Claude Code or Cursor, we highly recommend adding the AI SDK skill to your repository:

npx skills add vercel/ai

Provider Instance

You can import the default provider instance openai from @ai-sdk/openai:

import { openai } from '@ai-sdk/openai';

Example

import { openai } from '@ai-sdk/openai';
import { generateText } from 'ai';

const { text } = await generateText({
  model: openai('gpt-5-mini'),
  prompt: 'Write a vegetarian lasagna recipe for 4 people.',
});

Documentation

Experimental realtime models

Use the same factory for OpenAI Realtime and Live models:

openai.experimental_realtime('gpt-realtime');
openai.experimental_realtime('gpt-live-1');
openai.experimental_realtime('not-yet-released', { api: 'live' });

Live supports browser WSS sessions through an application-owned relay and experimental_useRealtime, with client delegation: your application owns the agent and tools. Optional browser-direct WebRTC is also available. Start with the OpenAI provider documentation for connection settings, startup options, and event mapping.

The experimental_useRealtime reference covers the JSON/PCM16 relay runtime, capture/playback controls, and application-handled client delegation, plus api.session WebRTC setup and server-owned data-channel permissions. Microphone capture requires browser permission; the application handles client delegation and submits context on either transport. The Realtime guide covers legacy token-based, turn-based sessions.

Runtime and provider authors can consult the repository's realtime integration notes.
