Kling 4.0 is the next-generation AI video model from Kling AI (Kuaishou), announced in September 2026, that generates up to 30 seconds of native video with stereo audio from text, image, and video references.
Kling 4.0 generates one continuous clip of up to 30 seconds, so long takes, emotion, action, and camera movement develop on a single narrative line instead of being stitched from short clips.
Kling 4.0 accepts up to 10 keyframe images, letting you pin character poses, scene changes, and story beats at chosen moments to build one-take sequences.
Kling 4.0 combines up to 10 images, 5 video clips, and 7 subjects in a single generation, so characters, motion, camera, and sound follow your references with fewer retries.
Kling 4.0 outputs high-quality dual-channel stereo sound and matches lip movement to dialogue more precisely, so voices, lines, and acting feel naturally in sync.
Kling 4.0 upgrades realism, creative control, and storytelling over earlier Kling models. Features marked coming soon have been announced by Kling but are not released yet.
Kling 4.0 keeps high-speed action, continuous movement, tracking shots, and orbit shots stable and coherent from the first frame to the last.
Kling 4.0 supports 21:9 ultra-wide framing for cinematic shots. Kling has also announced 4K and 1080p output in 10-bit HDR as coming soon, holding detail in backlit, night, and neon scenes.
Kling 4.0 adds, changes, or removes subjects and backgrounds in an existing video, and adjusts style, weather, color, material, and camera angle from text, image, or subject inputs.
Kling 4.0 analyzes the shot language and story structure of a reference video, then generates a new commercial video for social media, product ads, fashion and beauty, or electronics.
Kling 4.0 reads prompts up to 8,000 tokens and expands short ideas with director-style shot decisions, turning a one-line idea or a detailed script into a complete story.
Kling 4.0 Flash is the faster, lower-cost version of Kling 4.0 for high-volume creation. Kling opened limited Flash early access on its official platform on September 28, 2026.
Kling 4.0 AI runs in your browser with no install. These steps work today with Kling 3.0 and Kling 2.6, and will apply to Kling 4.0 once it is added.
Describe the scene, subject, and camera move in plain language, or upload a start image to animate it with image-to-video.
Pick Kling 3.0 for 3–15 second clips with optional native audio and multi-shot prompts, or Kling 2.6 for 5 or 10 second clips, then choose 16:9, 9:16, or 1:1.
Click Generate, follow progress in My Creations, and download the finished video for editing or publishing.
