About Grok Imagine Video 1.5 Preview

Grok Imagine Video 1.5 Preview is the preview build of xAI's Imagine Video 1.5 generation, released May 30, 2026 on AI Gateway. Grok Imagine Video 1.5 Preview generates video from an input image with synchronized audio in a single pass. Over the earlier Grok Imagine Video model, the 1.5 generation improves audio quality, prompt following, and photorealism. Face accuracy and character consistency hold across longer sequences, with better lighting and physical realism. Expanded reference image support gives more control over visual style and subject.

Integration runs through the AI SDK's generateVideo function, imported as experimental_generateVideo from AI SDK 6 or later. Pass a prompt object with an image and a text motion description. You control duration, aspect ratio, and resolution through parameters, with output available at 480p, 720p, and 1080p. Billing is per second of generated video, with rates by resolution shown on this page.

The stable grok-imagine-video-1.5 has since shipped as the production release of the same generation. Keep Grok Imagine Video 1.5 Preview for integrations you validated during the preview window, and plan new work against the stable model.
