WHAT IT DOES
Kling 4.0 is Kuaishou's next-generation Kling video model, announced September 28, 2026. It doubles the longest single generation to 30 seconds, continues a video across multiple shots up to 2 minutes, takes up to 15 references in text, image and video, and lets you pin up to 10 keyframes to control how a scene unfolds. Output goes up to 4K, with 10-bit HDR and a 21:9 ultra-wide ratio, plus stereo audio and more accurate lip sync. A lighter Kling 4.0 Flash went live the same day for Ultra Yearly subscribers only; Kling says the full Kling 4.0 is coming in October 2026.
WHY WE PICKED IT
Clip length and control are what limit AI video for real storytelling, and Kling 4.0 moves both: 30 seconds per generation and keyframes to steer the action, rather than regenerating until something usable appears. Kling 3.0 is already one of the directory's top-ranked video tools, so this is the upgrade to watch. It is listed now with its limited availability stated plainly.
