Kling 4.0 R2V is the reference-to-video entry point into Kuaishou's 4.0 generation of video models, released in October 2026. Rather than working from a prompt alone, it conditions generation on supplied reference imagery, letting a character, product, or visual style carry consistently through a generated clip — the typical requirement for editorial, advertising, and narrative work where a subject has to stay recognisably itself from shot to shot.

Within the Kling lineup it sits alongside the text-to-video and image-to-video builds of Kling 4.0, sharing the same generation's rendering quality while specialising in reference conditioning. It follows the same role played by Kling V3 4K R2V and Kling O3 4K R2V in earlier branches of the family, and contrasts with faster tiers such as Kling V3 Turbo Standard that trade polish for throughput.

Kuaishou, best known internationally for the Kwai short-video app, has oriented the Kling line around cinematic motion quality, and that focus shows most in human subjects — gesture, gait, and facial continuity. Best suited to creators who need character- or product-consistent footage across multiple shots, rather than one-off exploratory clips.
