## In short

Grok Imagine Video 1.5 is generally available on the xAI Imagine API, grok.com/imagine, and the Grok iOS and Android apps. xAI prices 720p output at $0.14 per second and says a 6-second 720p clip renders in about 25 seconds, down from 40+ in the prior model.

## What it is

Grok Imagine Video 1.5 is xAI's image-to-video model, generally available on the Imagine API plus grok.com/imagine and the Grok iOS and Android apps. It accepts a text prompt, an image, or up to seven reference images and returns short clips with sound effects, ambience, and speech synthesized in the same pass.

## How it works

Grok Imagine Video 1.5 generates 1–15 second clips at 480p or 720p in seven aspect ratios. xAI exposes three modes: text-to-video from a prompt alone, image-to-video that animates a still, and reference-to-video that grounds the output in up to seven reference images for consistent characters, styles, or settings. xAI says a Video 1.5 Fast pipeline renders a 6-second 720p clip in about 25 seconds, down from 40+ in the prior model.

## Why it matters

Putting a documented, pay-per-second image-to-video API in front of developers — $0.14 per second at 720p — gives Grok Imagine Video 1.5 a third serious generally-available slot alongside OpenAI Sora and Google Veo. Synchronized audio generated in the same pass is the feature xAI is pitching against rivals that require a separate audio step.

## Who it's for

App and creative-tool developers, marketing teams, social-media producers, animation pipelines.
