> **中国本土のユーザー向け：** 中国本土のユーザーは `https://toapis.cn` を API エンドポイント（Base URL）としてご利用ください。本ドキュメント内の例では `https://toapis.com` を `https://toapis.cn` に置き換えてください。

* Grok Video generation model

* Supports text-to-video and image-to-video

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