Released October 15, 2026, Kling 4.0 is Kuaishou's next-generation video model — longer clips (3–30 seconds), up to 4K, up to 10 keyframes, and an Omni Reference system — pitched at scenes with intense motion and complex camera moves.

Kuaishou launched Kling 4.0, the next generation of its Kling video model, with the full model becoming available to everyone on October 15, 2026. A faster, cheaper Kling 4.0 Flash tier had opened in limited early access on September 28, roughly two and a half weeks ahead of the main model. Kuaishou's own positioning puts motion at the center: Kling 4.0 is "designed for video creation scenarios featuring intense motion and complex camera movements," and the company says it holds subject structure, spatial relationships, and motion continuity together better during fast action and complicated camera work than earlier generations.
The headline spec changes are length and resolution. Kling 4.0 generates native clips from about 3 to 30 seconds — a large jump from the roughly 15-second ceiling of the Kling 3.0 line — at up to 4K, with support for a 21:9 ultrawide ratio. Kuaishou lists 10-bit HDR output at 1080p and 4K as "coming soon," so treat the top end of resolution and HDR as rolling out rather than fully shipped on day one. The model adds up to 10 flexible keyframes, letting you anchor specific visual moments across a longer generation instead of hoping a single prompt holds for the whole clip.
Control is the other theme. An Omni Reference system accepts up to 15 combined reference assets in one generation — reportedly up to 10 images, up to 5 videos, and several subjects, plus voice references to fix a character's voice — to steer appearance, actions, camera work, and setting. Audio improves too: higher-quality, two-channel stereo sound and sharper lip sync, with multilingual coverage that includes English, Chinese, and Korean. The Flash tier is tuned for speed and cost — shorter clips at 720p in standard dynamic range with text-to-video, image-to-video, and reference input.
Kling 4.0 lands in a crowded, fast-moving field alongside Google Veo, OpenAI's Sora line, ByteDance Seedance, and Alibaba's models, and it follows a record-setting year for the Kling unit, which raised nearly $3 billion in July 2026. Because Kuaishou iterates quickly and several 4.0 features are flagged as pending, treat clip lengths, resolution ceilings, HDR, and pricing as a snapshot and confirm the current spec on Kling's own site.
The most useful change in Kling 4.0 for a working creator is the 30-second clip, and it changes how you should treat the output: a long single-take action scene is a source reel, not a finished post. That is exactly where Kompozy earns its place. Run a Kling 4.0 render through Clipped Shorts and Kompozy pulls the strongest vertical moments out of the one generation — the hit, the turn, the reveal — so a single 4K scene becomes four or five posts instead of one upload. Each cut gets captions written in your voice through the Persona Brief, a clean reframe to 9:16, 1:1, and 16:9, and hook text stacked over the muted opening second via brand-exact HyperFrames — the fix for the thing that kills action clips on a silent-autoplay feed.
From there Kompozy generates the formats Kling doesn't touch and fans one scene into a week: a Carousel that walks the action beat by beat, a Quote Graphic, native Text Posts, a Blog Article, and an Email Newsletter, all held to one voice by banned-word governance, plus a face-locked Persona Short or avatar video for the reaction take. Then Autopilot and a per-post review pipeline schedule and publish the whole package across nine social platforms plus blog and email from one queue. Kling 4.0 makes the cinematic action; Kompozy is how that action actually reaches an audience — on-brand, sized for every feed, and everywhere at once.
Kling 4.0 is the next-generation video model from Kuaishou's Kling AI, made available to everyone on October 15, 2026. It generates native clips of roughly 3 to 30 seconds at up to 4K, adds up to 10 keyframes and an Omni Reference system, and is positioned for scenes with intense motion and complex camera movements.

The biggest changes are longer clips (about 3–30 seconds versus roughly 15 for Kling 3.0), higher resolution (up to 4K, with a 21:9 option and HDR coming soon), up to 10 keyframes, and a 15-asset Omni Reference system — all aimed at longer, more controllable, more motion-stable video. Confirm current specs on Kling's own site, since several 4.0 features are still rolling out.
No. Kling 4.0 generates the video and stops. To clip a 30-second render into shorts, caption it in your voice, size it per platform, fan it into other formats, schedule, and publish across nine platforms plus blog and email, use a content engine like Kompozy.
