Sources, read on 24 October 2026: Kling's Kling 4.0 vs 3.0 post (30 September) for the specs, and Kuaishou's press release of 19 October, carried by Bernama, for the launch date. fal's Kling 4.0 text-to-video page confirms the API modes. The quality claims below are Kling's, not Versely's own tests.
The launch, in order
Kling published its comparison of 4.0 and 3.0 on 30 September 2026 and said the full model would officially launch in October. A faster Kling 4.0 Flash had opened to "a limited group of users for early access" two days earlier, on 28 September. On 19 October Kuaishou announced that Kling 4.0 had officially launched on 15 October. By 24 October fal listed Kling 4.0 text to video and image to video in its API, and the model reached Versely the same day.
Kuaishou frames the release around three priorities: realism, control and professional quality. In practice that means three headline changes: steadier large-scale motion, native generation of up to 30 seconds, and Omni Reference, which takes up to 15 reference assets and up to 10 keyframes in one job.
What is new versus Kling 3.0
Kling's own comparison lists these differences:
| Spec | Kling 3.0 | Kling 4.0 |
|---|---|---|
| Clip length | 3-15 s | 3-30 s |
| Keyframes | Start and end | Up to 10 |
| Audio | Single-channel | Stereo |
| Dynamic range | 8-bit SDR | 10-bit HDR |
Kling gives 10-bit HDR at 1080p and 4K only. Both generations already offered 4K, so this is not a resolution upgrade.
Length. Thirty seconds in a single pass is the change most people will notice. Kling's argument is that a 15-second clip holds one main action, while 30 seconds leaves room to set a scene, develop it and end it on purpose. It also says the model is built to keep actions, camera moves and emotional beats continuous across the longer shot.
Keyframes. Kling 3.0 let you fix the first and last frame. Kling 4.0 takes up to 10 keyframe images, so you can set milestones along the timeline: a character enters at 0 s, the product appears at 6 s, the camera closes in at 12 s, and so on. That matters more as clips get longer.
References. One Kling 4.0 job can combine up to 15 assets: up to 10 images, 7 subjects, 5 videos (30 seconds combined), 3 video-based subjects and voice references. Kling 3.0 allowed up to 7 images or subjects, or one video plus 4.
Motion. Kling says fast action, several moving subjects, tracking and orbit shots hold together better than before, and names fight scenes, sport, dance and vehicle shots as the target.
Sound and language. Audio moves to two-channel stereo, with better lip-sync according to Kling. Spoken languages add Portuguese, German, French and Hindi to Kling 3.0's Chinese, English, Japanese, Korean and Spanish. Kling says on-screen text, logos and emoji also stay sharper through camera moves.
Editing and prompts. The full model edits existing footage (up to five input clips, 30 seconds combined), changing expressions, backgrounds, camera, weather or materials. A mode Kling calls Creative Recreation borrows the pacing and shot structure of a reference video and swaps in your own product or characters. Prompts can run to 8,000 tokens, though Kling says short prompts work too and the model will expand them.
Who it is for, and who should wait
Good fit:
- Long takes: a 20 to 30 second product walk-through, a tracking shot or a scene that needs to breathe, without stitching clips.
- Ads and social clips that need sound in the file, in 9:16 or 16:9.
- Cinematic framing: the Versely text-to-video row offers 21:9 as well as 16:9, 9:16 and 1:1.
- Image-to-video jobs where you control both ends with a start and an end frame.
Test first, or wait, if:
- You need 4K or HDR. Kling lists both, but the Versely rows output 720p or 1080p. For 4K today, the Kling Video V3 4K row is the one to use.
- Your plan depends on 10 keyframes, 15 references, video editing or Creative Recreation. Those are in Kling's own app; the Versely rows take a prompt, or a start image with an optional end frame.
- You want silent clips. Every Kling 4.0 clip on Versely comes with sound, so plan to mute or replace it in the edit.
- You only need 5 to 10 seconds. Kling 3.0 rows still cover that, and our Kling 3.0 guide explains which tier fits which job.

How to use it on Versely
Kling 4.0 runs on one Kling 4.0 model page in two modes: text to video, and image to video from a start image with an optional end frame. Clips run 3 to 15 seconds in one-second steps, or 20, 25 or 30 seconds, at 720p or 1080p.
On 24 October 2026 the model page showed Kling 4.0 from 19 credits, down from 38, for the shortest 720p clip. A 30-second 1080p clip costs up to 282 credits (564 before the discount). Price scales with length and resolution, and the model page always shows today's figure. For comparison on Versely, Kling Video V3 Standard text to video started at 26 credits and Kling 3 Turbo at 14 on the same day.
- Open the Kling 4.0 page and choose text or image to video.
- Write the shot as one continuous take: subject, setting, light, the camera move from start to finish, and what the scene should sound like.
- For long clips, describe the order of events ("first... then... as the camera rises...") so the 30 seconds have a shape.
- For image to video, add an end frame when the last shot matters, such as a product pack shot.
- Test at 720p and a short length, then render the keeper at 1080p and full length.
