Generate videos with Grok Imagine Video 1.5 Lite

Grok Imagine Video 1.5 Lite is the lightweight version of xAI's video model, released on October 1, 2026: a text or an image becomes a 1 to 15 second clip in 480p, with sound generated in the same pass, ambience, effects and voices. It is the cheapest video with sound in the catalog, built for exploring an idea, testing a camera move or producing drafts in bulk before moving to the full Grok Imagine Video 1.5 or to Seedance for the final version. It takes no reference images, only a start image.

12 credits per 5 s at 480p

Video with sound at the lowest price

Grok Imagine Video 1.5 Lite, released on October 1, 2026, keeps what makes Grok video 1.5: a text or a start image becomes a 1 to 15 second clip, and the sound, ambience, effects, voices, comes out in the same pass. It does so in 480p, for a per-second bill four times lower than the full 1.5.

It is the tool for drafts and series: testing a camera move, validating a shot idea, producing ten variants before handing the final version to 1.5 or Seedance. It takes no reference images and no video to edit, only a start image; our tests showed it always renders 480p, so that is the only tier offered.
