xAI 发布图生视频模型 Grok Imagine 1.5 Preview
Grok Imagine 1.5 Preview grok-imagine-video-1.5-preview, our latest image-to-video model, is now available via the xAI API in preview. Jun 3, 2026
- 1xAI 发布 grok-imagine-video-1.5-preview 图生视频模型，以预览版通过 xAI API 开放
- 2输入一张静态图加动作提示词即可生成视频，支持镜头运动、氛围与物理效果，分辨率最高 720p
- 3官方称模型保留原图细节与光影，可逐帧编排并串联成整段风格一致的长场景
- 4用户用自然语言描述镜头、节奏与声音设计，并自行设定分辨率和片段长度
xAI 把图生视频能力做成 API 预览版开放，内容团队获得一个可用代码调用的视频生成入口。
- 影响：营销与内容团队可把静态素材经代码批量转成视频片段，用于广告或社媒生产；预览版上限 720p，效果只有官方口径，需用自家素材实测后再扩量。
- 参考：可考虑挑一批品牌静态图做小规模试跑，记录与人工动画的成本和质感差异；先核对接投渠道是否接受 720p 素材，再定试点范围。
- 依据：能力描述与 720p 上限均出自 xAI 官方公告，属官方口径，暂无独立验证；未附第三方评测或性能数据。
Our latest image-to-video model, grok-imagine-video-1.5-preview, is now available via the xAI API in preview.
grok-imagine-video-1.5-preview turns a single still image into fluid, cinematic video. Give it a starting frame and a prompt describing the motion, and it animates the scene, including camera moves, atmosphere, and physics, while staying faithful to your source image. You can generate clips at up to 720p.
Direct the shot with natural-language prompts. Describe the camera move, the pacing, and the sound design, then set your resolution and clip length. The model holds detail and lighting from the input frame, so the result continues the original image rather than reinterpreting it.
The model also works well for sequences. Stage each frame, animate it, and chain the shots together into longer scenes that keep a consistent look across an entire project.
Animate an image in a few lines of code.
