Grok Imagine 1.5 AI video generator

Grok Imagine 1.5 is xAI’s image-to-video model, called Grok Imagine Video 1.5 in xAI’s API, where it was previewed on June 3, 2026, and became generally available on June 16, 2026. It turns a starting image into a clip of up to 15 seconds, with effects, ambience and dialogue generated alongside the picture, and it is on every DreamBench plan.

A Grok Imagine 1.5 clip runs up to 15 seconds. On DreamBench, a video can be longer, up to 30 seconds on Starter, 2 minutes on Plus and 5 minutes on Ultra and Studio, because DreamBench plans the scenes, generates each with Grok Imagine 1.5 and joins them.

Grok Imagine 1.5 renders at 720p or 1080p on DreamBench, both on the same model. You can frame it square (1:1), widescreen (16:9), portrait (9:16) or 4:3.

Yes. Every Grok Imagine 1.5 clip on DreamBench comes with sound: effects, ambience and dialogue generated together with the picture, and xAI says 1.5’s speech is easier to follow and better in sync than its previous model. Put a line in quotation marks and keep it short. xAI’s own API can also give up to 3 speakers a preset voice; on DreamBench the voice comes from the prompt.

Yes, through each clip’s opening frame. DreamBench draws that frame from your reference images, up to 8 per video, or from the characters and places it designs for you, and Grok Imagine 1.5 animates it; the model doesn’t receive the reference images directly. You can also write the prompt alone and let DreamBench draw the frame; xAI’s API likewise accepts a text prompt on its own.

Grok Imagine 1.5 on DreamBench is the API model xAI calls Grok Imagine Video 1.5. The Grok app and grok.com/imagine run Grok Imagine, including a Video 1.5 Fast variant, under xAI’s own accounts, quotas and resolutions. Queue, quota and resolution fallbacks in the Grok app don’t apply on DreamBench, where you pick 720p or 1080p and pay in credits.

Yes. Grok Imagine 1.5 costs credits to use on DreamBench, and credits come with a paid plan. It is on every plan, at a rate per second that depends on the resolution, plus a base amount per video, with sound always included; the composer shows the exact cost before you generate. You need no xAI account or API key: DreamBench runs Grok Imagine Video 1.5 through xAI’s API for you, in the browser on a phone, tablet or computer (Android, iPhone, Mac, Windows). xAI also sells it by the second through its API at its own rate.

Write a short shot brief: the camera move, the subject and what they do, when in the clip it happens, the setting and light, then the sound. Keep spoken lines short and in quotation marks. Because DreamBench draws the opening frame first, describe the motion you want from that frame.

Each clip runs to 15 seconds at up to 1080p, every clip comes with sound, and on DreamBench the model animates an opening frame rather than taking your reference images directly. If a scene misses, give it new direction and regenerate only that scene.

On DreamBench, Starter videos carry a small DreamBench watermark, which Plus, Ultra and Studio remove. xAI’s pages for Grok Imagine Video 1.5 don’t describe a watermark on its output.

Grok Imagine 1.5 and Kling 3.0 both run to 15 seconds a clip at up to 1080p; Veo 3.1 runs to 8 seconds. Every Grok Imagine 1.5 and Veo 3.1 clip comes with sound, while sound is optional on Kling 3.0. The compared table on this page lists the credits, and each model’s own page is linked below.

Grok Imagine 1.5 uses credits for each second of video, at a rate that depends on the resolution, plus a base amount per video, with sound always included. The table on this page shows the current rates, and you always see the exact cost before you generate.
