xAI Grok Provider

The xAI Grok provider contains language model support for the xAI API.

Setup

The xAI Grok provider is available via the @ai-sdk/xai module. You can install it with

pnpm add @ai-sdk/xai

Provider Instance

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

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

If you need a customized setup, you can import createXai from @ai-sdk/xai and create a provider instance with your settings:

import { createXai } from '@ai-sdk/xai';

const xai = createXai({
  apiKey: 'your-api-key',
});

You can use the following optional settings to customize the xAI provider instance:

• baseURL string

  Use a different URL prefix for API calls, e.g. to use proxy servers. The default prefix is https://api.x.ai/v1.

• apiKey string

  API key that is being sent using the Authorization header. It defaults to the XAI_API_KEY environment variable.

• headers Record<string,string>

  Custom headers to include in the requests.

• fetch (input: RequestInfo, init?: RequestInit) => Promise<Response>

  Custom fetch implementation. Defaults to the global fetch function. You can use it as a middleware to intercept requests, or to provide a custom fetch implementation for e.g. testing.

Language Models

You can create xAI models using a provider instance. The first argument is the model id, e.g. grok-beta.

const model = xai('grok-beta');

Example

You can use xAI language models to generate text with the generateText function:

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

const { text } = await generateText({
  model: xai('grok-2-1212'),
  prompt: 'Write a vegetarian lasagna recipe for 4 people.',
});

xAI language models can also be used in the streamText, generateObject, streamObject, and streamUI functions (see AI SDK Core and AI SDK RSC).

Chat Models

xAI chat models also support some model specific settings that are not part of the standard call settings. You can pass them as an options argument:

const model = xai('grok-2-1212', {
  user: 'test-user', // optional unique user identifier
});

The following optional settings are available for xAI chat models:

• user string

  A unique identifier representing your end-user, which can help xAI to monitor and detect abuse.
