Kling O3 4K

by Kuaishou

Kling O3 4K brings native 4K rendering to Kuaishou's Omni line, the reference-driven branch of the Kling 3.0 family. One model covers three modes, picking reference-to-video when reference images are supplied, image-to-video when a source frame is given, and text-to-video otherwise. Like O3 Pro it is built for reference-heavy production, keeping the look and sound of registered elements consistent across shots, with optional native audio. The 4K tier renders that output at full resolution without upscaling, which suits character-led campaigns and branded series headed for large-screen delivery.
