Grok Imagine is xAI’s generative media suite, and it stands out for range: where most video models stop at eight or ten seconds, Grok Imagine renders clips up to 30 seconds in a single pass, and the same family produces still images too. Elon Musk’s xAI positioned it as a fast, playful creation tool, and on Flux 3 AI you get the full toolkit with credits instead of a Grok subscription.
Six variants are wired into the platform. For video: text-to-video and image-to-video (each offering 6, 10, 15, or 30-second durations), the newer Grok Imagine 1.5 preview, plus two utilities — Extend, which continues an existing video, and Upscale, which sharpens finished footage. For stills, Grok Imagine text-to-image handles both text-to-image and image-to-image work in the image studio.
Video renders at 480p or 720p across five aspect ratios — 16:9, 9:16, 1:1, and the poster-friendly 2:3 and 3:2 — a wider framing menu than most competitors offer. A budget-friendly loop: draft long takes at 480p, pick the winner, then run it through Upscale; or generate a matching key art image and its motion version from one prompt.

What makes Grok Imagine stand out
30-second generations
Choose 6, 10, 15, or 30-second durations — enough runway for full jokes, walkthroughs, and narrative beats in one take.
Video and images together
One family covers moving and still output: Grok Imagine renders video in the Create studio and images in the image studio.
Five aspect ratios
Beyond 16:9 and 9:16, Grok Imagine frames 1:1, 2:3, and 3:2 — rare portrait and classic-photo formats for posters and feeds.
Extend tool
Feed a finished video back in and Grok Imagine Extend continues the shot, stretching a moment past its original length.
Upscale tool
Grok Imagine Upscale sharpens completed footage — draft cheaply at 480p, then upgrade the keeper instead of re-rendering.
1.5 preview access
The Grok Imagine 1.5 preview variant is available on Flux 3 AI, so you can test xAI’s newest generation as it evolves.

Which Grok Imagine version should you use?
Every version below is selectable in the Create studio on the same credits.
Grok Imagine (T2V)
The default starting point: describe a scene in text and render 6, 10, 15, or 30-second clips at 480p or 720p in any of five aspect ratios — 16:9, 9:16, 1:1, 2:3, or 3:2. Pick it when you have no source material, since every other video variant assumes an existing image or clip.
Grok Imagine (I2V)
Starts from an uploaded image instead of a blank canvas, animating your still with the same menu as text-to-video: 6 to 30-second durations, 480p or 720p, five aspect ratios. Choose it when the composition, character, or product look is already decided and only the motion is missing.
Grok Imagine 1.5 Preview
xAI’s newest generation in preview form. It accepts a text prompt or an image input and renders 6 or 10-second clips at 480p or 720p across the full five-ratio menu. Pick it to test where 1.5 is heading; stay on the main variants when a take needs 15 or 30 seconds.
Grok Imagine Extend
A utility rather than a generator: feed in a finished video and Extend continues the shot in 6 or 10-second passes at 480p or 720p. Reach for it when a clip ends too soon — it stretches a moment you already like instead of creating a new one from scratch.
Grok Imagine Upscale
The finishing pass of the family. Upscale takes a completed video and sharpens it, working in 16:9 or 9:16 at 480p or 720p. Use it to rescue economical 480p drafts before publishing — the second half of the draft-cheap-then-enhance loop this family is built around.
Grok Imagine Image
The stills side of Grok Imagine, found in the image studio rather than the video Create studio. It covers both text-to-image and image-to-image work, making it the pick for poster art, key frames, and artwork that needs to match clips produced by the video variants.
Grok Imagine prompt examples
Copy one as a starting point, or send it straight to the Create studio.
“A skateboarder carves through a neon-lit skate park at dusk, low tracking camera alongside, sparks flying off a rail grind, energetic handheld feel, one continuous 30-second take”
Uses the full 30-second duration for an unbroken narrative run
“A street-food vendor flips noodles in a flaming wok at a night market, slow push-in, red lantern glow, smoke curling through the frame, vertical 9:16”
Tests fire, smoke, and fluid motion in a vertical format
“Retro sci-fi movie poster of an astronaut riding a giant koi above a glowing city, bold flat colors, dramatic rim lighting, centered composition, 2:3 portrait”
An image-mode prompt showing the poster-friendly 2:3 still format

Grok Imagine questions, answered
What is Grok Imagine?
Grok Imagine is xAI’s generative media model, covering both video and image creation. On Flux 3 AI it appears as six variants — text-to-video, image-to-video, a 1.5 preview, extend and upscale utilities, and a text-to-image mode — all usable from the browser with credits.
How long can Grok Imagine videos be?
Up to 30 seconds in a single generation — you can pick 6, 10, 15, or 30-second durations for text-to-video and image-to-video. That 30-second ceiling is several times longer than most mainstream AI video models produce per clip.
Does Grok Imagine generate images as well as video?
Yes. Grok Imagine’s text-to-image variant lives in the Flux 3 AI image studio and handles both text-to-image and image-to-image generation, so you can produce matching stills and motion from the same model family.
What resolutions and aspect ratios does Grok Imagine support?
Video renders at 480p or 720p, with five framing options: 16:9, 9:16, 1:1, 2:3, and 3:2. The two portrait-photo ratios make it a strong pick for poster-style and print-inspired compositions.
Can I extend or upscale a Grok Imagine video?
Both. The Extend variant takes an existing video and continues it in 6 or 10-second passes, while the Upscale variant enhances finished footage — a practical way to polish a 480p draft you already like.
What is Grok Imagine 1.5?
Grok Imagine 1.5 is xAI’s newer generation, available on Flux 3 AI as a preview variant. It takes a text prompt or an image input, renders 6 or 10-second clips at 480p or 720p, and supports the same five aspect ratios as the main variants.
How do I use Grok Imagine without a Grok or X subscription?
Generate on Flux 3 AI. A free account comes with starter credits that work on Grok Imagine and every other listed model, downloads carry no platform watermark, and credit plans on the pricing page cover heavier use.
Grok Imagine vs Sora 2 — which should I pick?
Pick Grok Imagine for length and format flexibility: 30-second clips, five aspect ratios, and built-in extend and upscale tools. Pick Sora 2 for maximum realism in short 1080p clips. Since both run on Flux 3 AI, comparing them on your own prompt costs only a few credits.
