# xAI Grok Provider

The [xAI Grok](https://x.ai) provider contains language model support for the [xAI API](https://x.ai/api).

## Setup

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

<Tabs items={['pnpm', 'npm', 'yarn', 'bun']}>
  <Tab>
    <Snippet text="pnpm add @ai-sdk/xai" dark />
  </Tab>
  <Tab>
    <Snippet text="npm install @ai-sdk/xai" dark />
  </Tab>
  <Tab>
    <Snippet text="yarn add @ai-sdk/xai" dark />
  </Tab>

  <Tab>
    <Snippet text="bun add @ai-sdk/xai" dark />
  </Tab>
</Tabs>

## Provider Instance

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

```ts
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:

```ts
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&lt;string,string&gt;_

  Custom headers to include in the requests.

- **fetch** _(input: RequestInfo, init?: RequestInit) => Promise&lt;Response&gt;_

  Custom [fetch](https://developer.mozilla.org/en-US/docs/Web/API/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](https://console.x.ai) using a provider instance. The
first argument is the model id, e.g. `grok-3`.

```ts
const model = xai('grok-3');
```

By default, `xai(modelId)` uses the Chat API. To use the Responses API with server-side agentic tools, explicitly use `xai.responses(modelId)`.

### Example

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

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

const { text } = await generateText({
  model: xai('grok-3'),
  prompt: 'Write a vegetarian lasagna recipe for 4 people.',
});
```

xAI language models can also be used in the `streamText`, `generateObject`, and `streamObject` functions
(see [AI SDK Core](/docs/ai-sdk-core)).

### Provider Options

xAI chat models support additional provider options that are not part of
the [standard call settings](/docs/ai-sdk-core/settings). You can pass them in the `providerOptions` argument:

```ts
const model = xai('grok-3-mini');

await generateText({
  model,
  providerOptions: {
    xai: {
      reasoningEffort: 'high',
    },
  },
});
```

The following optional provider options are available for xAI chat models:

- **reasoningEffort** _'low' | 'medium' | 'high'_

  Reasoning effort for reasoning models.

- **store** _boolean_

  Whether to store the generation. Defaults to `true`.

- **previousResponseId** _string_

  The ID of the previous response. You can use it to continue a conversation. Defaults to `undefined`.

## Responses API (Agentic Tools)

You can use the xAI Responses API with the `xai.responses(modelId)` factory method for server-side agentic tool calling. This enables the model to autonomously orchestrate tool calls and research on xAI's servers.

```ts
const model = xai.responses('grok-4-fast');
```

The Responses API provides server-side tools that the model can autonomously execute during its reasoning process:

- **web_search**: Real-time web search and page browsing
- **x_search**: Search X (Twitter) posts, users, and threads
- **code_execution**: Execute Python code for calculations and data analysis

### Vision

The Responses API supports image input with vision models:

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

const { text } = await generateText({
  model: xai.responses('grok-2-vision-1212'),
  messages: [
    {
      role: 'user',
      content: [
        { type: 'text', text: 'What do you see in this image?' },
        { type: 'image', image: fs.readFileSync('./image.png') },
      ],
    },
  ],
});
```

### Web Search Tool

The web search tool enables autonomous web research with optional domain filtering and image understanding:

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

const { text, sources } = await generateText({
  model: xai.responses('grok-4-fast'),
  prompt: 'What are the latest developments in AI?',
  tools: {
    web_search: xai.tools.webSearch({
      allowedDomains: ['arxiv.org', 'openai.com'],
      enableImageUnderstanding: true,
    }),
  },
});

console.log(text);
console.log('Citations:', sources);
```

#### Web Search Parameters

- **allowedDomains** _string[]_

  Only search within specified domains (max 5). Cannot be used with `excludedDomains`.

- **excludedDomains** _string[]_

  Exclude specified domains from search (max 5). Cannot be used with `allowedDomains`.

- **enableImageUnderstanding** _boolean_

  Enable the model to view and analyze images found during search. Increases token usage.

### X Search Tool

The X search tool enables searching X (Twitter) for posts, with filtering by handles and date ranges:

```ts
const { text, sources } = await generateText({
  model: xai.responses('grok-4-fast'),
  prompt: 'What are people saying about AI on X this week?',
  tools: {
    x_search: xai.tools.xSearch({
      allowedXHandles: ['elonmusk', 'xai'],
      fromDate: '2025-10-23',
      toDate: '2025-10-30',
      enableImageUnderstanding: true,
      enableVideoUnderstanding: true,
    }),
  },
});
```

#### X Search Parameters

- **allowedXHandles** _string[]_

  Only search posts from specified X handles (max 10). Cannot be used with `excludedXHandles`.

- **excludedXHandles** _string[]_

  Exclude posts from specified X handles (max 10). Cannot be used with `allowedXHandles`.

- **fromDate** _string_

  Start date for posts in ISO8601 format (`YYYY-MM-DD`).

- **toDate** _string_

  End date for posts in ISO8601 format (`YYYY-MM-DD`).

- **enableImageUnderstanding** _boolean_

  Enable the model to view and analyze images in X posts.

- **enableVideoUnderstanding** _boolean_

  Enable the model to view and analyze videos in X posts.

### Code Execution Tool

The code execution tool enables the model to write and execute Python code for calculations and data analysis:

```ts
const { text } = await generateText({
  model: xai.responses('grok-4-fast'),
  prompt:
    'Calculate the compound interest for $10,000 at 5% annually for 10 years',
  tools: {
    code_execution: xai.tools.codeExecution(),
  },
});
```

### File Search Tool

xAI supports file search through OpenAI compatibility. You can use the OpenAI provider with xAI's base URL to search vector stores:

```ts
import { createOpenAI } from '@ai-sdk/openai';
import { streamText } from 'ai';

const openai = createOpenAI({
  baseURL: 'https://api.x.ai/v1',
  apiKey: process.env.XAI_API_KEY,
});

const result = streamText({
  model: openai('grok-4'),
  prompt: 'What documents do you have access to?',
  tools: {
    file_search: openai.tools.fileSearch({
      vectorStoreIds: ['your-vector-store-id'],
      maxNumResults: 5,
    }),
  },
});
```

<Note>
  File search requires grok-4 family models. See the [OpenAI
  provider](/providers/ai-sdk-providers/openai) documentation for additional
  file search options like filters and ranking.
</Note>

### Multiple Tools

You can combine multiple server-side tools for comprehensive research:

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

const { fullStream } = streamText({
  model: xai.responses('grok-4-fast'),
  prompt: 'Research AI safety developments and calculate risk metrics',
  tools: {
    web_search: xai.tools.webSearch(),
    x_search: xai.tools.xSearch(),
    code_execution: xai.tools.codeExecution(),
  },
});

for await (const part of fullStream) {
  if (part.type === 'text-delta') {
    process.stdout.write(part.text);
  } else if (part.type === 'source' && part.sourceType === 'url') {
    console.log('\nSource:', part.url);
  }
}
```

### Provider Options

The Responses API supports the following provider options:

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

const result = await generateText({
  model: xai.responses('grok-4-fast'),
  providerOptions: {
    xai: {
      reasoningEffort: 'high',
    },
  },
  // ...
});
```

The following provider options are available:

- **reasoningEffort** _'low' | 'high'_

  Control the reasoning effort for the model. Higher effort may produce more thorough results at the cost of increased latency and token usage.

<Note>
  The Responses API only supports server-side tools. You cannot mix server-side
  tools with client-side function tools in the same request.
</Note>

## Live Search

xAI models support Live Search functionality, allowing them to query real-time data from various sources and include it in responses with citations.

        ],
      },
    },
  },
});
```

### Sources and Citations

When search is enabled with `returnCitations: true`, the response includes sources that were used to generate the answer:

```ts
const { text, sources } = await generateText({
  model: xai('grok-3-latest'),
  prompt: 'What are the latest developments in AI?',
  providerOptions: {
    xai: {
      searchParameters: {
        mode: 'auto',
        returnCitations: true,
      },
    },
  },
});

// Access the sources used
for (const source of sources) {
  if (source.sourceType === 'url') {
    console.log('Source:', source.url);
  }
}
```

### Streaming with Search

Live Search works with streaming responses. Citations are included when the stream completes:

```ts
import { streamText } from 'ai';

const result = streamText({
  model: xai('grok-3-latest'),
  prompt: 'What has happened in tech recently?',
  providerOptions: {
    xai: {
      searchParameters: {
        mode: 'auto',
        returnCitations: true,
      },
    },
  },
});

for await (const textPart of result.textStream) {
  process.stdout.write(textPart);
}

console.log('Sources:', await result.sources);
```

<Note>
  The table above lists popular models. Please see the [xAI
  docs](https://docs.x.ai/docs#models) for a full list of available models. The
  table above lists popular models. You can also pass any available provider
  model ID as a string if needed.
</Note>

## Image Models

You can create xAI image models using the `.image()` factory method. For more on image generation with the AI SDK see [generateImage()](/docs/reference/ai-sdk-core/generate-image).

```ts
import { xai } from '@ai-sdk/xai';
import { experimental_generateImage as generateImage } from 'ai';

const { image } = await generateImage({
  model: xai.image('grok-2-image'),
  prompt: 'A futuristic cityscape at sunset',
});
```

<Note>
  The xAI image model does not currently support the `aspectRatio` or `size`
  parameters. Image size defaults to 1024x768.
</Note>

### Model-specific options

You can customize the image generation behavior with model-specific settings:

```ts
import { xai } from '@ai-sdk/xai';
import { experimental_generateImage as generateImage } from 'ai';

const { images } = await generateImage({
  model: xai.image('grok-2-image'),
  prompt: 'A futuristic cityscape at sunset',
  maxImagesPerCall: 5, // Default is 10
  n: 2, // Generate 2 images
});
```
