The model

Kling O3 4K

by Kuaishou

Kuaishou Kling O3 (Omni line) in native 4K, served via fal. One id covers text-, image- and reference-to-video: reference images select reference-to-video, a source image selects image-to-video, otherwise text-to-video. Audio is OFF by default here (unlike Kling 3.0); the 4K rate is the same with or without audio. Richer per-subject control rides through parameters.elements (each {frontal_image_url, reference_image_urls:[...], voice_id} or {video_url}), cited in the prompt as @Element1, @Element2.
