alibaba/wan/2.2/5b/fast/text-to-video
Wan 2.2 5b is Alibaba's text-to-video AI model. Turn written scripts and prompts into professional-quality video clips with realistic motion, lighting, and scene composition.
Input
The text prompt to guide video generation.
The aspect ratio of the generated image. Allowed values: 21:9, 16:9, 3:2, 4:3, 5:4, 1:1, 4:5, 3:4, 2:3, 9:16.
Resolution of the generated video (580p or 720p). Allowed values: 480p, 580p, 720p.
110
Classifier-free guidance scale. Higher values give better adherence to the prompt but may decrease quality. Range: 1 to 10.
Random seed for reproducibility. If None, a random seed is chosen.
04
Number of frames to interpolate between each pair of generated frames. Must be between 0 and 4. Range: 0 to 4.
17161
Number of frames to generate. Must be between 17 to 161 (inclusive). Range: 17 to 161.
If true, the number of frames per second will be multiplied by the number of interpolated frames plus one. For example, if the generated frames per second is 16 and the number of interpolated frames is 1, the final frames per second will be 32. If false, the passed frames per second will be used as-is.
The quality of the output video. Higher quality means better visual quality but larger file size. Allowed values: low, medium, high, maximum.
460
Frames per second of the generated video. Must be between 4 to 60. When using interpolation and `adjust_fps_for_interpolation` is set to true (default true,) the final FPS will be multiplied by the number of interpolated frames plus one. For example, if the generated frames per second is 16 and the number of interpolated frames is 1, the final frames per second will be 32. If `adjust_fps_for_interpolation` is set to false, this value will be used as-is. Range: 4 to 60.
If set to true, output video will be checked for safety after generation.
The model to use for frame interpolation. If None, no interpolation is applied. Allowed values: none, film, rife.
The write mode of the output video. Faster write mode means faster results but larger file size, balanced write mode is a good compromise between speed and quality, and small write mode is the slowest but produces the smallest file size. Allowed values: fast, balanced, small.

Wan
Wan is the Wan 2.2 speed-oriented workflow for prompt-led video. It models visual appearance and time together so the route’s written direction, source imagery, speech, masks, or structural conditions influence one coherent result rather than a collection of disconnected frames or a generic endpoint response.
Choose this exact route when the available assets and deliverable specifically call for prompt-led video. Identify every subject and source, state the desired action or transformation, then describe camera behavior, pacing, environment, lighting, atmosphere, and preservation requirements; local schema fields handle resolution, duration, seed, and delivery separately from the creative brief.
Highlights
- 2.2 Fast Written-scene filmmaking. Builds subjects, action, setting, and shot language from a text brief.
- 2.2 Fast Temporal motion coherence. Maintains plausible movement and interaction across consecutive frames.
- 2.2 Fast Cinematic camera interpretation. Responds to framing, lens behavior, camera movement, and pacing.
- Compact 5B fast synthesis. Uses the smaller Wan 2.2 architecture for speed-oriented prompt-to-video generation.
Pricing
| Configuration | Billing unit | Price |
|---|---|---|
| Base generation | Per request | $0.025 |
When to Use
| ✅ Good fit | ❌ Consider alternatives |
|---|---|
| The project needs this exact named workflow | The intended task belongs to another media route |
| All required reference or control media is available | Necessary assets or rights are unavailable |
| The brief can state transformation and preservation goals | Output must be deterministic at pixel or frame level |
| Supported duration, resolution, and format fit delivery | Final placement requires unsupported specifications |
| An asynchronous generated result fits production | A live frame-synchronous response is mandatory |
Prompt Guide
Identify the primary subject and every source or condition, state the intended transformation or action, then describe composition, camera or viewpoint, lighting, materials, pacing, atmosphere, and exact preservation requirements. Refer to multiple inputs in their schema order.
