Grok Imagine 1.5 is xAI’s image-to-video model, and it generates the soundtrack together with the picture. On DreamBench it animates each clip of your video from an opening frame DreamBench draws, and you can redo any scene without starting over.

**What Grok Imagine 1.5 is.** Grok Imagine 1.5 is a video model from xAI. It reached xAI’s API as a preview on June 3, 2026, and became generally available on June 16, under the name Grok Imagine Video 1.5. xAI presents it as an image-to-video model: it turns a starting picture into a clip of up to 15 seconds, at up to 1080p. xAI says 1.5 improves on its previous video model in motion, physics and sound: less warping, more convincing weight across a whole clip, and speech that is easier to follow and better in sync. The model creates effects, ambience and dialogue alongside the images, matched to what happens on screen. xAI also offers a variant called Grok Imagine Video 1.5 Fast on grok.com/imagine and in its iOS and Android apps. DreamBench uses the model from xAI’s API, grok-imagine-video-1.5.

**What Grok Imagine 1.5 is good at.**
- Sound made with the picture: Effects, ambience and dialogue are generated with the picture, so a skid, a splash or a shouted line arrives with the movement that makes it.
- Motion and physics, improved: xAI says 1.5 improves on its previous model in motion and physics, which suits action scenes: a jump, a tumble, a wave breaking over a wall.
- Made to animate a still: xAI built 1.5 to bring a starting image to life. DreamBench draws that image for each clip from the characters and places in your video, and Grok Imagine 1.5 sets it moving.
- Up to 15 seconds a clip: Each generation can run up to 15 seconds, long enough for an action to build, land and settle within a single clip.

**Grok Imagine 1.5 on DreamBench.**
- Grok Imagine 1.5 makes both 720p and 1080p video on DreamBench, on the same model, and every clip comes with sound.
- Your reference images don’t go to Grok Imagine 1.5 directly. DreamBench draws an opening frame for each clip from them, or from the characters and places it designs for you, and the model animates that frame.
- In xAI’s own API, Grok Imagine 1.5 can also make a silent clip, pin the last frame of a clip, work from a text prompt alone or from reference images and give a subject one of xAI’s preset voices. On DreamBench, you shape each scene with your prompt and reference images, and change it by giving it new direction.

**Prompt ideas.**
- Down the forest trail: A single 15-second shot, vertical 9:16. A mountain biker in a red helmet races down a muddy forest trail, skids around a root-covered bend, launches off a dirt jump and lands in a spray of mud. The camera follows low behind her back wheel, then swings round as she brakes hard and punches the air. Tires tearing through mud, birds scattering, her shout of “Yes!”.
- Storm at the harbor: Widescreen 16:9. A storm wave explodes against a stone harbor wall and throws spray over stacked fish crates as a trawler rolls through the swell behind. A fisherman in yellow oilskins grabs a mooring rope and shouts, “Hold her steady!” The camera stays low behind a bollard as the water drains back. Booming surf, hissing foam, clanking rigging, crying gulls.
- Friday night on the line: A 4:3 shot of a busy restaurant kitchen on a Friday night. A chef tosses vegetables in a flaming wok while a second cook slides plates onto the pass and calls, “Service, please!” Steam rolls under the lights as the camera weaves between them. Sizzling oil, clattering pans and the ticket printer chattering.
- The honest review: Vertical 9:16, filmed like a phone video. A young man in a hoodie sits at his kitchen table holding a new pair of wireless earbuds up to the camera. He pops one in, nods along to the music and says, “Okay, these actually block out the kettle.” Behind him the kettle starts to boil. Morning light through the window, the click of the charging case, a muffled beat.

**Grok Imagine 1.5 FAQ.**
- **What is Grok Imagine 1.5?** 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.
- **How long can a Grok Imagine video be?** 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.
- **What resolution does Grok Imagine 1.5 use on DreamBench?** 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.
- **Does Grok Imagine 1.5 make sound and lip-sync dialogue?** 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.
- **Can Grok Imagine 1.5 animate a photo or use reference images?** 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.
- **Is Grok Imagine 1.5 the same as Grok Imagine in the Grok app?** 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.
- **Does Grok Imagine 1.5 cost anything to use?** 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.
- **What makes a good Grok Imagine 1.5 prompt?** 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.
- **What are Grok Imagine 1.5’s limits?** 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.
- **Are Grok Imagine 1.5 videos watermarked?** 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.
- **How does Grok Imagine 1.5 compare with Kling 3.0 and Veo 3.1 on DreamBench?** 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.
