Use Wan 2.5 Preview privately on Venice
On Venice, Wan 2.5 Preview runs with full prompt privacy — your inputs are anonymized and not stored. This means you can generate videos without surveillance or data retention, ideal for creators and enterprises prioritizing sovereignty. As an open and uncensored model, it enables permissionless innovation while maintaining audio-visual fidelity.
What can Wan 2.5 Preview do?
- •Native audio-video synchronization — generates ambient sound, music, and lip-synced speech in one pass, eliminating post-production dubbing.
- •Dual input modes — supports both text-to-video and image-to-video generation, enabling animation of stills with motion cues.
- •Open weights allow self-hosting, fine-tuning, and auditability — rare among high-fidelity video models.
- •Strong prompt adherence with cinematic control language (e.g., 'dolly shot', 'slow motion').
- •Available on Venice with zero retention — prompts are not stored or profiled.
- •Limited to short clips (5s or 10s), making it unsuitable for long-form content.
- •Audio quality can be robotic in complex dialogue; background music and effects are more reliable.
- •Faces and fine details may drift during motion, especially in image-to-video mode.
- •No support for custom motion curves or frame-level editing in the preview version.
Sample outputs
Generated on Venice with our standard prompt suite — the same prompts we run through every model of this type, so you can judge it like-for-like.
Slow aerial drone shot gliding over a misty mountain valley at golden hour, sunlight piercing clouds onto a winding river, ancient pine forests on either side, ultra-smooth motion, professional color grading, atmospheric haze, 4K
Calm ocean waves rolling onto a black-sand beach at sunrise, golden light on wet sand, foam dissolving into the shore, a single silhouetted figure at the waterline, smooth continuous forward push, serene cinematic atmosphere
A slow tracking shot through a rain-soaked Tokyo street at night, neon reflecting in puddles, steam rising from a food cart, a person with a translucent umbrella, shallow depth of field, teal-and-orange grade, smooth steady camera

Yes. Venice runs Wan 2.5 Preview with anonymized privacy — no prompts are stored, profiled, or used for training. This makes it ideal for sensitive or commercial use cases requiring data sovereignty.
No. Wan 2.5 Preview is a generative video model and does not support tool use, function calling, or reasoning over external APIs. It generates video from prompts or images only.
Yes. The image-to-video variant 'wan-2.5-preview-image-to-video' accepts a still image as input and animates it into motion based on a text prompt.
Wan 2.7 is a newer version with longer clip support, improved motion consistency, and higher fidelity. Wan 2.5 Preview is an earlier release optimized for short, audio-synced clips and open deployment.
No. Wan 2.5 Preview does not perform web search or access real-time information. It generates video based solely on the provided prompt or image input.
It has limited reasoning — it follows cinematic language and prompt structure well, but does not perform logical inference or multi-step planning like a language model.
It generates clips of exactly 5 seconds or 10 seconds — no intermediate durations. This is fixed in the current preview version.
The model ID for the image-to-video variant is 'wan-2.5-preview-image-to-video'.
