# Grok Video Generation

> Generate high-quality videos using Grok Video model

* Grok Video generation model
* Select `grok-video-3` model via the model parameter
* Supports text-to-video and image-to-video
* Async task management, query results via task ID

<Warning>
  **Important Change**: For better performance and cost control, we no longer support passing base64 image data directly in `images`. Please use the [Upload Image API](/docs/en/api-reference/uploads/images) to upload images first, then call this API with the returned URL.
