Grok for volume

Lite is a faster, lower-cost model distilled from Grok Imagine Video 1.5. It keeps synchronized sound and lip-synced speech, trading some quality for speed and price — for drafts, social clips and high-volume pipelines.

From text or a first frame

Describe a scene, or give it an image to open on and describe the motion and sound; the clip keeps the image's shape.
