Kling 4.0 is the newest AI video model from Kling AI, released in October 2026. It makes videos up to 30 seconds long in one generation, with stable action, accurate lip sync, and stereo sound.
What is Kling 4.0?
Kling 4.0 is the latest AI video model from Kling AI, made by the Chinese tech company Kuaishou. It's the follow-up to Kling 3.0, and it launched on October 15, 2026.
The big shift: Kling 4.0 is built for directing whole scenes, not just making short clips. You set the characters, the key moments, and the shots, and it keeps everything steady for up to 30 seconds.
Kling 4.0 features
Capture any action. Match every sound.
Stable big motion: fast chases, spinning camera moves, and crowd scenes stay smooth from start to finish.
More accurate lip sync: dialogue and singing match every word.
Stereo audio: sound that feels like it's all around you.
1080p with 10-bit HDR: richer color and more detail, especially in night and neon scenes.
21:9 ultrawide: a true movie-screen look.
Keep every character consistent.
Omni Reference: add up to 15 references (images, videos, and elements) so your characters, products, and scenes stay the same in every shot.
Recreate a video you love: keep its pacing and shots, and swap in your own character.
Edit with precision: change an expression, camera angle, or background without redoing the whole video.
Tell every story.
Up to 30 seconds in one generation: no stitching clips together.
Up to 10 keyframes: lock in the key moments and shape how your story unfolds. (A keyframe is a moment in the video you set ahead of time.)
Smarter prompts: start simple or go detailed, and Kling 4.0 fills in the director's touch.
Create in any style. Speak any language. Claymation, documentary, glitch art, felt, 3D, and more, plus many languages and accents and clear on-screen text.

Marcus, a young soldier with a scar on his left cheek and a red cloak, in a crowded army camp at dawn. 0–3s: he wakes up and pushes open his tent flap. 3–6s: he eats bread by the fire with his friends. 6–9s: he marches out through the fort gates as the sun rises.

A friendly animated octopus narrator with big curious eyes floats in a glowing coral reef. 0–2s: it swims into frame and looks into the camera. 2–9s: it says, "Did you know octopuses have three hearts? Here's why." Bright colors, playful 3D style, gentle bubbling ocean sounds.
Stay in character across scenes, from the opening shot to the last line.

Vertical 9:16, 9 seconds. A lone explorer with a flashlight in an abandoned 1920s hotel at night. 0–3s: she pushes open the creaking front doors. 3–6s: she walks slowly past a dusty grand piano. 6–9s: she looks up the staircase as a light flickers on the floor above.
