# Grok in ComfyUI: AI Image and Video Generation

> Use xAI's Grok models in ComfyUI: Grok Imagine Image for text-to-image and image editing, and Grok Imagine Video for video generation, editing, and extension

Grok is xAI's family of generative models, available in ComfyUI through the Grok partner nodes. It covers image generation and editing with **Grok Imagine Image** and video generation, editing, and extension with **Grok Imagine Video**, across multiple model versions.

<Tip>
  To use the Partner Nodes, you need to ensure that you are logged in properly and using a permitted network environment. Please refer to the [Partner Nodes Overview](/tutorials/partner-nodes/overview) section of the documentation to understand the specific requirements for using the Partner Nodes.

      Make sure your ComfyUI is updated.

      * [Download ComfyUI](https://www.comfy.org/download)
      * [Update Guide](/installation/update_comfyui)

      Workflows in this guide can be found in the [Workflow Templates](/interface/features/template).
      If you can't find them in the template, your ComfyUI may be outdated.

      If nodes are missing when loading a workflow, possible reasons:

      1. You are not using the latest ComfyUI version (Nightly version)
      2. Some nodes failed to import at startup

    <Tab title="Cloud users">
      * [Cloud](https://cloud.comfy.org) will update after ComfyUI stable release.

      So, if you find any core node missing in this document, it might be because the new core nodes have not yet been released in the latest stable version. Please wait for the next stable release.
