Grok Imagine AI Video Generator
Create Stylized AI Videos with xAI's Aurora Engine in Grok Imagine
Grok Imagine is xAI's video generation model, powered by the Aurora autoregressive engine and trained on the Colossus supercomputer with 110,000 NVIDIA GB200 GPUs. It generates 6 or 10 second clips at 480p or 720p with native audio, supports text-to-video and image-to-video, and ships with three distinct style modes — Fun, Normal, and Spicy — that let you change the creative tone of any prompt with one click.
Grok Imagine 1.0 reached general availability on February 2, 2026, after launching as a preview in 2025. The model is built on Aurora, xAI's autoregressive frame-prediction architecture, which renders sequentially from left to right rather than via diffusion. The training run used the Colossus supercomputer with 110,000 NVIDIA GB200 GPUs — one of the largest training infrastructures in AI video to date — and the public surface has already produced more than 1.245 billion videos in a single 30 day window.
The model offers two input modes inside LoveGen AI. Text-to-video accepts a prompt up to 2,000 characters and renders motion across five aspect ratios — 16:9, 9:16, 1:1, 3:2, and 2:3 — covering landscape, portrait, square, and classic photographic framings. Image-to-video accepts a single reference image (JPG, JPEG, PNG, or WebP, up to 20 MB) and animates it according to your prompt. Both modes generate at 24 fps in either 6 or 10 second durations, with output capped at 720p.
The defining feature is the style mode toggle. Normal mode keeps the output balanced and faithful to your prompt. Fun mode pushes toward playful, exaggerated, creative interpretations. Spicy mode unlocks edgier, more dramatic renders. Audio is native to Aurora — dialogue with lip-sync, background music, and ambient sound effects come out of a single forward pass without any second-stage post-processing. On March 2, 2026 xAI shipped Extend from Frame, which chains clips together using the final frame of one as the start of the next, and the model returns a finished 6 or 10 second clip in roughly 30 seconds on average. Generation runs asynchronously inside LoveGen AI — submit the job and the finished video drops into your gallery so you can preview, download, and compare it directly against Sora 2, Veo 3.1, Seedance 2.0, and Happy Horse 1.0 in the same workspace.
How to Use Grok Imagine
Step 1: Choose Text-to-Video or Image-to-Video
Toggle between text-to-video for prompt-only generation, or image-to-video to animate a reference image you upload.
Step 2: Pick Your Settings
Select duration (6s or 10s), resolution (480p or 720p), aspect ratio (T2V only), and style mode (Fun or Normal).
Step 3: Generate and Download
Click Generate. Aurora returns a finished clip with native audio in roughly 30 seconds — preview, download, or compare it side by side with other models in your gallery.

Why Choose Grok Imagine
Aurora Autoregressive Engine
Grok Imagine is built on Aurora, xAI's frame-by-frame autoregressive video model trained on 110,000 NVIDIA GB200 GPUs — a fundamentally different approach from diffusion-based competitors and a key reason its motion feels distinct.
Three Style Modes Out of the Box
Fun, Normal, and Spicy let you dial creative tone without rewriting your prompt. Most video models give you one look; Grok Imagine gives you three from the same input.
Native Audio in a Single Pass
Dialogue with lip-sync, ambient sound, and background music are produced jointly with the video — no separate audio stage, no synchronization drift.
