Use it privately on Venice
On Venice, you can generate video with Grok Imagine under the private tier. Your creative prompts are processed with zero retention: they are immediately discarded, never stored, profiled, or used to train external models. Enjoy permissionless private video creation without Big Tech surveillance.
What can it do?
- •Native audio generation — Automatically synthesizes synchronized sound effects, dialogue, and background music directly with the video.
- •Top-tier instruction following — Highly accurate translation of complex text prompts into coherent visual motion and scene composition.
- •Flexible aspect ratios — Supports 7 different aspect ratios ranging from widescreen 16:9 to vertical 9:16 for social media.
- •Excellent motion control — Capable of rendering realistic camera movements like pans, tilts, and zooms smoothly.
- •High-velocity prototyping — Fast generation speeds make it ideal for rapid creative iteration and storyboarding.
- •Resolution capped at 720p, whereas some competitors support native 1080p output.
- •Closed-source and proprietary, preventing local hosting, fine-tuning, or weight inspection.
- •Maximum clip duration is capped at 15 seconds per generation.

Frequently asked questions
Grok Imagine is xAI's state-of-the-art video generation model, released in January 2026. It produces high-quality video clips up to 15 seconds long at 720p resolution, complete with native, synchronized audio including dialogue, sound effects, and music.
On Venice, Grok Imagine is priced per clip based on resolution and duration. A 5-second clip at 480p resolution costs $0.32, while a 5-second clip at 720p resolution costs $0.44. Longer durations up to 15 seconds scale accordingly.
You can try Grok Imagine on Venice using free trial credits provided to new accounts. For regular or high-volume usage, you can purchase Venice credits to pay per video clip, with no monthly subscription required.
No, Grok Imagine is a closed-source, proprietary model developed by xAI. Its weights are not publicly available for local hosting or fine-tuning. If you require an open-weights alternative, you can explore Wan 2.7 on Venice.
Yes, Grok Imagine natively supports audio generation. Unlike many video models that generate silent clips, Grok Imagine automatically synthesizes synchronized sound effects, dialogue, and background music directly aligned with the generated video.
Grok Imagine excels at native audio generation and rapid prototyping at 720p resolution. Kling O3 Pro supports higher native 1080p resolution and highly advanced cinematic motion, but does not include integrated audio generation. Choose Grok for complete multimedia clips and Kling for high-definition cinematic visuals.
Venice runs Grok Imagine under its private tier. Your prompts are processed with zero retention: they are immediately discarded, never stored, profiled, or used for model training, ensuring a private creation workflow.
Grok Imagine supports seven different aspect ratios: widescreen (16:9), classic (4:3, 3:2), square (1:1), and vertical formats (2:3, 3:4, 9:16), making it highly versatile for both cinematic projects and vertical social media content.
