Kling 4.0: 30-second clips with sound
Kuaishou's new video model makes clips up to 30 seconds long with synchronized sound.
Kling 4.0 came out on October 15, 2026. It makes clips of up to 30 seconds with synchronized sound, guided by up to 10 keyframes, and it can follow reference images, videos and voices.
It renders at 720p and 1080p, with 4K announced as coming soon. It is not on the Artificial Analysis video board yet, so there is no independent ranking to quote.
Kling 4.0 is not on Staglight yet. You can already make clips with Kling 3.0, and with Seedance 2.5, which ranks 5th for text to video with sound on Artificial Analysis.
