Grok Video 1.5 Lite: Features, Pricing, and Prompt Guide

Grok Imagine Video 1.5 Lite gives creators a lower-cost way to test short video ideas in xAI’s video model family. It takes a written scene or a starting image and generates a clip with audio. For product teasers, portrait animation, and social video concepts, the useful question is how much iteration you can afford before choosing a final shot.

Vercel’s model listing dates the release to October 1, 2026; its AI Gateway announcement followed on October 8. This guide reviews the published specifications as of October 9, with suggested prompts rather than hands-on test results.

What Grok Video 1.5 Lite Supports

The official model ID is grok-imagine-video-1.5-lite. According to xAI’s video overview, Lite supports:

Setting	Lite capability
Generation modes	Text-to-video and image-to-video
Clip duration	1–15 seconds
Output resolutions	480p, 720p, 1080p
1080p output	Upscaled from 720p
Audio	Native audio, including lip-synced speech
Image-to-video framing	Matches the input image’s aspect ratio

1080p output is not native 1080p generation. Inspect fine details at your delivery size before choosing that setting for a product shot.

Lite vs. Grok Imagine Video 1.5

Lite focuses on text and starting-image generation. The full grok-imagine-video-1.5 model adds native 1080p, multiple reference images, voice references, and first/last frame and intermediate keyframe controls. Lite does not support those reference or frame controls. Neither 1.5 variant supports the older model’s video editing and extension modes. These distinctions come from xAI’s capability comparison.

Choose Lite for a single scene you can describe clearly. Consider the full model when your brief needs specific references or an exact ending composition. Treat that as a workflow choice; published specifications do not establish which model will produce your best shot.

API Pricing: Resolution Changes the Cost

The xAI Lite model card lists the following output rates. The example totals are calculated for a six-second clip:

Resolution	Output price per second	Six-second output cost
480p	$0.02	$0.12
720p	$0.03	$0.18
1080p	$0.14	$0.84

Image input is listed at $0.01 per image, charged separately. A six-second image-to-video request at 720p with one image therefore totals $0.19 at these rates.

The full 1.5 model card lists $0.08, $0.14, and $0.25 per output second at 480p, 720p, and 1080p respectively. Lite’s output rate is 75% lower at 480p; the same percentage does not apply to every resolution.

These are xAI API prices, not PixVerse credit prices or consumer subscription fees. Check your provider’s current charge before submitting a request.

A Practical Workflow for PixVerse Creators

Start by preparing your visual brief in PixVerse. You can create a source image there and use the same composition to compare video workflows. This guide does not confirm Lite availability on PixVerse; select it only where your provider explicitly offers the Lite model.

Choose one action. Write a brief such as “the bottle stays still while the camera moves closer.” Avoid packing several scene changes into the first test.
Prepare the first frame. For image-to-video, compose the image in the intended format before generating.
Run a short draft. Try six seconds at 480p or 720p, keeping the prompt and image fixed.
Review motion and sound together. Check object shape, hands, camera stability, dialogue timing, and unwanted background noise.
Change one instruction at a time. Record what improved, then choose the resolution for your final version. Allow budget for a fresh generation rather than assuming a new request will reproduce the draft exactly.

Two Prompts to Try

These are starting points to test, not examples of verified output.

Animate a Product Image

Upload your product still, then describe the motion and the details that should stay consistent:

Animate this product photo into a six-second teaser. Keep the bottle shape, label, and tabletop consistent. The camera slowly moves closer while soft window light shifts across the glass. Gentle room ambience, no speech or music. One continuous shot, no added text.

Generate a Scene from Text

Specify the subject, action, camera, lighting, and sound:

A six-second vertical shot of a small paper boat drifting across a shallow puddle after rain. Low camera angle, slow sideways tracking, warm evening reflections. Soft water sounds and distant city ambience. One continuous shot, no scene cuts or on-screen text.

If the result is too busy, simplify the action before adding more stylistic instructions. Review generated text, logos, and speech individually before using a clip in a campaign.

Frequently Asked Questions

Is Grok Video 1.5 Lite the Same as SuperGrok Lite?

They refer to different things: this article covers a video model identified by grok-imagine-video-1.5-lite. For consumer subscriptions, consult the separate Grok plan information.

How Can I Try It?

Use xAI’s API with the model ID above, or a provider that lists it. Vercel also offers it through AI Gateway and its playground, as described in the Gateway announcement. Provider settings and billing can differ.

Should I Choose Lite for Every Video?

Use it to explore a simple short scene and evaluate whether it fits your brief. For references, precise frame control, or native 1080p, compare the full 1.5 model’s documented capabilities. For your PixVerse workflow, check the models and settings available in your account.
