Kling 4.0 preview · example from the referenced showcase
Kling 4.0 is the next generation of the Kling AI video model family. It turns text or images into video, combines visual and voice references, and lets creators plan individual moments with multiple keyframes. Its focus is a more coherent scene: believable movement, stable subjects and sound that follows the performance.
Five creative directions from the Kling 4.0 announcement. Explore reference inputs alongside the published video examples.
01 / 05
Keep fast action and expressive performances readable, even when the camera moves.
Tracking and orbit shots, subtle facial expressions, lip-sync and two-channel stereo bring the visual performance and its sound into the same scene.
02 / 05
Guide the subject, movement and visual style with Omni Reference.
Combine up to 15 items across images, videos, voice references and subjects. The individual limits include 10 images, 5 videos totaling 30 seconds and 7 subjects; these share the overall 15-item budget.
03 / 05
Plan important visual moments instead of leaving every transition to chance.
Single-generation clips span 3–30 seconds. Up to 10 keyframe images guide character states, scene changes and story beats. Longer action can unfold in one continuous take.
04 / 05
Explore product films, short dramas, animation and campaigns for different audiences.
The announced model covers a wider range of visual styles, multilingual dialogue and readable in-scene text. Use references to keep product identity and composition aligned while exploring a new style.
05 / 05
A separate Kling 4.0 variant designed for frequent creative iteration.
Flash is announced with 3–20 second output at 720p and 8-bit SDR. It supports text-to-video, first-frame image-to-video and Omni Reference. The full model’s 4K and 10-keyframe specifications should not be assumed for Flash.

Prepare prompts, images and references for Kling 4.0. Explore these creative starting points while generation is coming soon.
Start with a scene, one clear action, a camera move and the sound you want. Useful for original shots and early story exploration.
Bring a product photograph, portrait or illustration. Describe what moves and what should remain unchanged.
Plan visual and motion references to keep your subject consistent across the scene.
Describe the subject, action, setting, camera and audio. For a long take, define the beginning, middle and ending. These are original example prompts, not claims about generated results.
01
A matte-black perfume bottle on a wet stone plinth at dawn. Start in a close-up of water droplets, slowly orbit the bottle, then pull back to reveal the coastline. Keep the label unchanged. One continuous shot, soft side light, natural ocean ambience, no spoken dialogue.
02
Two friends meet outside a quiet café at sunset. The woman stops, smiles and says, “I thought you had left.” The man turns and replies, “Not without saying goodbye.” A gentle push-in, natural pauses, consistent faces, street ambience and clearly synchronized speech.
03
Begin with the explorer at the entrance of a glass greenhouse. In the middle, follow her as she discovers a glowing plant. End with a close-up of her surprised expression. Match the supplied keyframe images and outfit, keep the action continuous, and use a smooth tracking camera.
Start with the control your scene needs. Kling 4.0’s announcement highlights multiple keyframes, stereo performance and reference-led direction. Seedance 2.5 offers a different reference and editing workflow in this studio. Compare real model availability and matching settings before choosing; there is no universal quality winner for every prompt.
Kling4.0 / Kling4 and Kling AI 4.0 are common ways to refer to Kling 4.0, the next generation of Kling AI’s video model family. The lineup includes a full model and the separate Flash variant.
The official announcement states an October launch and says limited Kling 4.0 Flash early access began September 28. It does not give a specific October launch day in the referenced note. Check the linked official release notes for current availability.
Kling 4.0 coming soon. Generation is not available on this website yet. This guide presents announced capabilities and published examples; availability will be updated here.
The official specifications list 720p, 1080p and 4K output for the full model. The release note separately marks 10-bit HDR at 1080p and 4K as coming soon. Flash is listed at 720p. Check the official interface for the output mode available to your account.
The full model is announced for 3–30 seconds in a single generation; Flash for 3–20 seconds. Repeated video extension up to two minutes is described as coming soon and is different from a single-generation duration.
The announced full model accepts up to 10 keyframe images to guide important visual moments. A keyframe defines a moment in the sequence; an ordinary reference guides appearance, style or motion without necessarily fixing a specific point in time.
The full model lists a combined maximum of 15 items across images, videos, voice references and subjects. Within that total: up to 10 images, 5 videos totaling 30 seconds and 7 subjects, including at most 3 video-based subjects. These are overlapping limits, not quantities to add together.
The full model announcement lists two-channel stereo, synchronized dialogue and voice reference input. Audio reference input is for voice reference only. The Flash specification table does not separately confirm the same audio output settings.
The full model lists up to 30-second clips, 4K output and multi-keyframe control. Flash lists up to 20-second clips, 720p, 8-bit SDR, text-to-video, first-frame image-to-video and Omni Reference, with an emphasis on frequent iteration.
This page does not offer Kling 4.0 generation or quote an official 4.0 price. Access and trial credits depend on Kling AI’s current rollout and account terms. Our pricing page covers credits for the models already connected to this studio.
The full model announcement describes targeted video editing. It lists up to five input clips with one primary clip; each is 3–30 seconds, and their total duration must not exceed 30 seconds. Actual access depends on the official rollout.
