# xAI

xAI is a platform for providing endpoints for Large Language models.

## Authentication

Set your `XAI_API_KEY` environment variable. You can get one [from xAI here](https://console.x.ai/).

<CodeGroup>
  ```bash Mac theme={null}
  export XAI_API_KEY=sk-***
  ```

  ```bash Windows theme={null}
  setx XAI_API_KEY sk-***
  ```
</CodeGroup>

## Example

Use `xAI` with your `Agent`:

<CodeGroup>
  ```python agent.py theme={null}

  from phi.agent import Agent, RunResponse
  from phi.model.xai import xAI

  agent = Agent(
      model=xAI(id="grok-beta"),
      markdown=True
  )

  # Get the response in a variable
  # run: RunResponse = agent.run("Share a 2 sentence horror story.")
  # print(run.content)

  # Print the response in the terminal
  agent.print_response("Share a 2 sentence horror story.")

  ```
</CodeGroup>
