Kling O3 4K R2V brings Kuaishou's high-end reference-to-video pipeline to 4K, generating cinematic clips guided by reference imagery rather than text or a single seed frame. Released in April 2026, it sits in the O3 generation of the Kling family, which Kuaishou — the Chinese short-video giant behind the Kwai app — has tuned for lifelike human motion and editorial-grade scene composition.

Within the lineup it is the reference-to-video specialist, complementing the text-driven Kling O3 4K and the image-driven Kling O3 4K variants released the same day. It also runs parallel to the V3 track's Kling V3 4K R2V, giving creators a choice of model generations at the same resolution. As the newest entry in its reference-to-video line, it represents the current state of that workflow.

This model is best suited for creators who want to anchor a generated video to specific reference visuals — preserving a subject, style, or look — while leaning on Kling's strengths in fluid human movement and polished, film-like framing at 4K.
