What is Kling 4?

Kuaishou’s longest take yet.

Kling 4.0 is the fourth generation of Kling, the video model of Kuaishou Technology. Kuaishou launched it on October 15, 2026, after a faster Kling 4.0 Flash opened in limited early access on September 28.

Its focus is control over long shots: a single generation lasts up to 30 seconds, you can pin up to 10 keyframes along the way, and Omni Reference mixes images, videos, characters and a voice in one request.

Kling 4 is coming to Nano Banana. Until it lands, every other model runs in the same subscription: in the Video Studio, in Banana Computer, by API or MCP. Looking for Kling-style results today? See our Kling alternative page.
