Kuaishou's next-generation Kling video model — 30-second clips, up to 4K, 10 keyframes, and an Omni Reference system, built for scenes with intense motion and complex camera moves.

Kling 4.0 is the next-generation model of Kuaishou's Kling AI video line, made available to everyone on October 15, 2026, after a faster, cheaper Kling 4.0 Flash tier opened in limited early access on September 28. Kuaishou positions it explicitly for motion: it 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 through fast action than earlier Kling generations. For the scored verdict on the model itself, see the [Kling 4.0 review](/reviews/kling-4-0).
The headline change is scale. Native generation now runs from about 3 to 30 seconds — roughly double the ~15-second ceiling of the Kling 3.0 line — at resolutions up to 4K, with support for a 21:9 ultrawide ratio. Kuaishou lists 10-bit HDR at 1080p and 4K as "coming soon," so treat the very top of the resolution range as rolling out rather than fully shipped. Up to 10 flexible keyframes let you anchor specific visual moments across a longer clip instead of relying on a single prompt to hold the whole thing together.
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 up to 7 subjects, plus voice references to fix a character's voice — to steer appearance, actions, camera work, and setting. Audio improves to higher-quality, two-channel stereo with sharper lip sync and multilingual coverage including English, Chinese, and Korean. The Flash tier trades resolution and length for speed and price (shorter clips at 720p in standard dynamic range) for drafts and volume.
The honest boundary is the same one every generation model has: Kling 4.0 hands you a finished-looking scene and stops. It does not clip a 30-second render into shorts, caption in your brand voice, size a clip for six feeds, build a carousel or a blog, or schedule and publish anything. Kuaishou iterates quickly and several 4.0 features are flagged as pending, so treat clip lengths, resolution ceilings, HDR, and prices as a moving snapshot and confirm them on Kling's own site before quoting.
Kling 4.0's real edge is motion — a 30-second action scene that keeps its structure through fast movement and complex camera work, held consistent by the Omni Reference system. But a motion-heavy clip is the single worst thing to ship raw: on a muted autoplay feed, an action scene with no words is just unexplained chaos, and the Omni consistency you worked to get is wasted if the post around it doesn't look like your brand. Kompozy is the finishing layer that sits directly on that output. Drop a Kling 4.0 render in and Kompozy burns in captions styled to your brand, stacks a hook over the silent opening second via brand-exact HyperFrames so the action lands before anyone taps unmute, and reframes the clip cleanly to 9:16, 1:1, and 16:9 for each destination. The reference consistency you steered in Kling, Kompozy carries forward into a post that unmistakably reads as you.
Then it multiplies. Because a 30-second clip is really a source reel, Kompozy's Clipped Shorts pulls the strongest vertical moments into separate posts, and one scene fans into a whole content unit: a brand-exact Carousel breaking the sequence down, a Quote Graphic, native Text Posts, a Blog Article, and an Email Newsletter — every piece governed by your Persona Brief and banned-word filters so the volume still sounds like you, not a generic model. Kompozy also makes the formats Kling can't touch — Persona Shorts and HeyGen avatar video with a face-locked recurring identity, delivering your script in 175+ languages for real multilingual reach, plus Persona Frames and Marketing Shorts. Finally it does the part no generator does: schedules and publishes the whole package across nine social platforms plus blog and email from one queue, on Autopilot with a per-post review pipeline. Generate the action in Kling 4.0; make it captioned, on-brand, multiplied, and everywhere in Kompozy.
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 (up to 15 combined assets), and is built 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, a 15-asset Omni Reference system, and a motion-focused design for high-speed action. Several 4.0 features were still rolling out at launch, so confirm current specs on Kling's own site.
Kling 4.0 Flash is the faster, cheaper tier of the 4.0 generation — shorter clips at 720p in standard dynamic range, with text-to-video, image-to-video, and reference input. It opened in limited early access on September 28, 2026, ahead of the full model, and is built for speed, drafts, and volume.
No. It generates the clip but does not clip a long render into shorts, caption in your voice, brand it, size it per platform, schedule, or publish. To turn a Kling 4.0 render into finished, on-brand posts across nine platforms plus blog and email, use a content engine like Kompozy.
