Mode-specific validation rules
| Model slug | Mode | Duration | Resolution | Required input |
|---|---|---|---|---|
wan_2_6_flash_i2v |
Image to video | 5, 10 or 15 seconds | 720p or 1080p | Prompt (2-1500 characters) plus exactly one input_image_urls value (jpeg/png/webp, at least 256x256). The output inherits the image aspect ratio. |
wan_2_6_flash_v2v |
Video to video | 5 or 10 seconds | 720p or 1080p | Prompt (2-1500 characters) plus one to three input_video_urls values (mp4/mov/mkv, up to 10 MB each). |
The sound flag decides the price and the native audio track: audio costs twice the silent rate and is always submitted as an explicit on/off value.
Pass multi_shots (boolean) to let the model plan multiple shots.
