Grok Imagine Video 1.5 Lite with Native Audio

Grok Imagine Video 1.5 Lite is xAI's lowest-cost model in the Video 1.5 family for generating short clips from text or a starting image. It produces videos lasting 1 to 15 seconds with native audio and lip-synced speech.

Turn a written prompt into a complete video, or animate an existing image as the opening frame of a new scene. Both generation modes can produce synchronized dialogue, ambient sound, and effects in the same pass.

Choose the text-to-video endpoint for prompt-only generation or the image-to-video endpoint when you have a starting frame. Enter a prompt, select the duration and resolution, then submit the request. For image animation, also provide the required source image.

Yes, the model generates audio natively alongside the visuals and supports lip-synced speech. Describe the intended dialogue, ambience, and sound effects in your prompt so they can be incorporated into the scene.

Clips can run from 1 to 15 seconds and use 480p, 720p, or 1080p output. The 1080p option is upscaled from 720p rather than rendered at native 1080p.

Your supplied image becomes the first frame, while the prompt directs subsequent motion, camera behavior, and audio. The generated clip follows the aspect ratio of that source image.

Atlas Cloud lists a standard price of $0.02 per generated second for both the text-to-video and image-to-video endpoints. Billing scales with the requested output duration under pay-as-you-go pricing.

Lite prioritizes lower-cost text-to-video and image-to-video generation for simpler production needs. The full Video 1.5 model is intended for workflows requiring reference images, voice references, pinned frames, or native 1080p output. Choose Lite when cost-efficient iteration matters more than those advanced controls.
