Kling v3

Kling v3 is Kuaishou’s Kling VIDEO 3.0 model. Use kling-v3 for text-to-video or image-to-video with first-frame or first-and-last-frame control, at 720p or 1080p, from 3 to 15 seconds, with optional native audio.

text-to-video: omit image_urls.
image-to-video: 1 image sets the first frame; 2 images set the first and last frame.

kling-v3 is a separate model key from kling-ai. Use Kling v3 Omni when you need multiple reference images.
