Availability
Where Kling 4.0 stands right now
Kling announced Kling 4.0 at the end of September 2026 and said the full model is coming in October. The first thing to ship was Kling 4.0 Flash, a faster tier limited to 720P, and it opened only to Kling Ultra yearly subscribers inside Kling's own app. No public API has been released, and no pricing has been published.
That means any site offering “Kling 4.0 generation” before the API opens should be treated with caution. On Froging AI, this page is honest about the gap: the generator runs Kling 3.0, which already supports text-to-video, image-to-video, 4K output, and optional audio. The prompts you refine now will carry over when Kling 4.0 arrives.
For the full breakdown of what was announced, what is still unconfirmed, and how Kling 4.0 compares with Kling 3.0, read our Kling 4.0 release guide.

Prompt workflow
Write prompts that are ready for Kling 4.0
Longer clips and keyframes reward the same discipline that works in Kling 3.0: a clear subject, ordered beats, one camera behavior, and sound tied to visible action. Practice these in the generator above so your prompts are ready on day one.
Example to try with Kling 3.0 (15s): A barista in a green apron pours steamed milk into a white cup on a wooden counter. First, the milk stream thins and a leaf pattern forms. Then she slides the cup toward the camera and smiles. Finally, steam rises as morning light shifts across the counter. Slow push-in at counter height, warm window light, quiet café ambience with the soft hiss of the steam wand.
- 1
Write one shot, not a montage
Even with 30 seconds available, decide what the whole clip is about before adding beats. One subject and one location keep longer generations coherent.
- 2
Split the time into beats
Describe what happens at the start, the middle, and the end. This habit transfers directly to Kling 4.0 keyframes.
- 3
Anchor the look with an image
Use Image to Video with Kling 3.0 today to lock the product, character, or style. Kling 4.0 will extend this with multiple references.
- 4
Give the camera one job
A slow push-in, a tracking shot, or a locked frame. Changing camera behavior every sentence makes long clips drift.
- 5
Describe sound with the action
Tie each sound to something visible, such as footsteps, a door, or a spoken line, rather than adding generic music.
