Grok Imagine Video 1.5 Lite

Grok Imagine Video 1.5 Lite is xAI’s model for generating short videos from text instructions or a starting image. Its current documentation gives a 1–15-second duration range.

Resolution changes the price

The xAI video documentation lists the following direct rates:

The 1080p option is upscaled from 720p. A ten-second 720p generation at the listed direct rate therefore costs $0.30. Provider billing and supported settings can differ, so check the service being used.

Providers added it on different dates

Runware’s changelog records availability on 2 October 2026. Vercel added the model to AI Gateway on 8 October. The release-list date uses the earlier documented provider availability.

For a production workflow, test the motion, continuity and adherence to the input image at the intended duration and resolution. Cost comparisons are most useful when they include retries and the proportion of clips that are suitable for use.
