4 ways to generate, one endpoint

Set mode, send the inputs it needs — that's it.

Text to video

mode: "t2v" · prompt

Just a prompt — the model builds the shot from scratch.

Image to video

mode: "i2v" · image_url

Send an image in image_url and it becomes the opening frame.

First and last frame

mode: "flf" · image_url + last_image_url

Set the first and last frame; the model animates everything in between.

Reference to video

mode: "r2v" · reference_images (≤ 5)

Add up to 5 reference images to lock in characters, products and style.
