Wan 是什么？
Wan 是阿里开源的视频生成模型系列。权重公开，任何人都能下载运行——但跑它需要 GPU 算力，这就是各家托管服务收费的原因。
Open-weight, not a black box
The weights are public. You can run Wan yourself in ComfyUI if you own the GPU — this site just saves you the hardware and the setup.
Native audio, already in sync
Footsteps land when feet land. Speech matches mouth movement. Syncing audio afterwards is the slowest part of short video, and Wan removes it.
Text-to-video and image-to-video
Build a scene from a sentence, or keep your own photo and add motion to it. Image-to-video gives you far more control over the result.
Honest about cost
Wan 2.5 costs about $0.05 per second at 480p and $0.15 at 1080p in real GPU time. We tell you where the free tier ends instead of surprising you.
为什么选这里
把成本讲清楚，把能做什么和不能做什么讲清楚。
怎么用
三步出片：写提示词或传图 → 选模型 → 生成。
Start from text or a photo
Upload an image to animate it, or skip straight to a prompt if the scene does not exist yet.
Describe the motion, not the picture
"Camera slowly pushes in, her hair moves in the wind" beats "a beautiful woman". The model can already see the image — tell it what changes.
Pick length and resolution
5 or 10 seconds, 480p or 1080p. Iterate at 480p, then re-run the prompt you like at 1080p. Cheapest way to work.
Generate and download
Roughly 1–3 minutes. Audio comes back with the clip, already timed.
能力
文生视频、图生视频，多档分辨率与多个模型可选。
Native audio generation
Sound is produced with the video in a single pass and arrives already synced.
480p and 1080p
Draft at 480p, deliver at 1080p. Roughly a 3× cost difference between them.
5 or 10 second clips
The native length of short-form video. Join several clips for anything longer.
16:9, 9:16 and 1:1
Landscape for YouTube, vertical for Shorts and Reels, square for feeds.
Image-to-video that keeps your subject
Your photo stays recognisable — the model adds motion rather than reinventing the scene.
Open weights
Run it yourself in ComfyUI whenever you want. No lock-in, unlike closed models.
