What Is Kling 4.0?
Kling 4.0 is the next generation of Kling's AI video system, designed to combine text, images, videos, subjects and voice references in a more complete production workflow. It has been officially announced, with Kling 4.0 Flash entering limited early access. The generator on this page continues to use the available Kling 3.0 task until Kling 4.0 is integrated.

Kling 4.0 Brings Story-Level Control to Video Generation
The main upgrade is not one isolated quality setting. It is the ability to direct a longer, reference-rich sequence as a connected piece of video.
Build a Complete Scene in Up to 30 Seconds
A single generation can hold a setup, a change and an ending. That gives actions and emotional beats enough time to develop without stitching together a stack of short clips.
- Use 3 to 30 seconds for short moments or complete scenes
- Describe pacing and shot changes inside one longer prompt
- Keep the character and setting connected across the sequence
Direct Kling 4.0 With Up to 10 Keyframes
Keyframes let you define the visual moments that matter most. Set character states, scene changes and important story beats, then let the model build the motion between them.
- Move beyond a single first-and-last-frame transition
- Place turning points across a longer sequence
- Control composition and narrative timing more deliberately
Combine More Creative References in Kling 4.0
Omni Reference brings several kinds of direction into one generation. Images can define characters and composition, videos can guide motion and pacing, and a voice reference can help anchor a subject.
- Use up to 10 images and up to 5 reference videos
- Define up to 7 subjects within the announced input limits
- Combine no more than 15 total reference items
Create Richer Picture, Sound and Visual Styles
Kling 4.0 pairs more stable movement with stereo audio, improved lip sync, clearer generated text and a wider range of visual treatments for commercial and personal work.
- Generate synchronized dialogue and environmental sound
- Work across cinematic, documentary, animation and 3D styles
- Use 21:9 framing for wider, more cinematic compositions
What Changes From Kling 3.0 to Kling 4.0?
Kling 4.0 expands the current workflow from controlled short clips toward longer scenes with more reference inputs and more points of direction.
| Capability | Kling 3.0 | Kling 4.0 |
|---|---|---|
| Single-generation duration | 3 to 15 seconds | 3 to 30 seconds |
| Frame direction | First frame and optional last frame | First and last frames plus up to 10 keyframes |
| Reference workflow | Text and frame-based modes in the current generator | Omni Reference with images, videos, subjects and voice |
| Prompt capacity | Up to 2,500 characters in the current generator | Up to 8,000 tokens in the announced specification |
Kling 3.0 values reflect the task currently available in this generator. Kling 4.0 values reflect the official announced specification and will be verified against the final integrated model.
