Kling AI releases Kling 4.0 video model on OnSolo with 30-second clips

AIKling 4.0 extends native video generation to 30 seconds, and Leiphone's tests found it could handle a vintage-style rain dance but struggled with a sword-sleeve drum scene. Its video editing changed a dancer's suit color while keeping the rest of the footage, though the editing credit cost was close to regenerating the clip. Kling 4.0 launched on October 15, and the article reports it also extended generation to 30 seconds.

AIKling AI says Kling 4.0 is now available on OnSolo. The model generates 30 seconds of native video in one take, with stereo sound, sharper lip sync and 21:9 widescreen output. Users can combine up to 15 references and 10 keyframes in one job to keep characters and shots consistent.
