Generate videoGet API keyWhat is Kling O3 4K?
Kling O3 4K is Kuaishou's flagship unified multimodal AI video model, launched in February 2026. It generates 4K cinematic clips up to 15 seconds from text, images, or reference subjects, featuring native audio, multi-shot storyboarding up to six cuts, and visual chain-of-thought reasoning for coherent scene logic.
Use Kling O3 4K privately on Venice
On Venice you run Kling O3 4K with zero retention — your prompts are anonymized and not stored, profiled, or used for training. You pay per clip from $1.39 for a 3-second generation, scaling with duration and resolution, so you only spend for what you render. It is the same Kuaishou 4K pipeline, accessed privately without tying generations to a personal account history.
What can Kling O3 4K do?
- •Cinematic 4K output with native audio and frame-perfect lip-sync, backed by ultra high-res and audio collections on Venice.
- •Visual chain-of-thought reasoning plans scene logic, motion paths, and lighting before rendering, improving coherence across frames.
- •Multi-shot storyboard control supports up to six camera cuts in a single 15-second clip for complex narrative sequencing.
- •Three input modes — text-to-video, image-to-video, and reference-to-video — let you lock character consistency across scenes.
- •Long-duration generation up to 15 seconds, longer than many competing video models.
- •Closed and proprietary — no open weights, so you cannot self-host, fine-tune, or audit the model.
- •Per-clip pricing scales with duration and 4K resolution, making rapid iteration more expensive than flat-rate or open-weights alternatives.
- •Benchmark reports suggest cheaper rivals occasionally outperform it on raw prompt adherence despite superior feature coverage.
- •Maximum 15-second duration is still restrictive for longer narrative or documentary scenes.
- •Runs on Venice with anonymized privacy only — not inside a TEE or end-to-end encrypted environment.
Sample outputs
Generated on Venice with our standard prompt suite — the same prompts we run through every model of this type, so you can judge it like-for-like.
Slow aerial drone shot gliding over a misty mountain valley at golden hour, sunlight piercing clouds onto a winding river, ancient pine forests on either side, ultra-smooth motion, professional color grading, atmospheric haze, 4K
Calm ocean waves rolling onto a black-sand beach at sunrise, golden light on wet sand, foam dissolving into the shore, a single silhouetted figure at the waterline, smooth continuous forward push, serene cinematic atmosphere
A slow tracking shot through a rain-soaked Tokyo street at night, neon reflecting in puddles, steam rising from a food cart, a person with a translucent umbrella, shallow depth of field, teal-and-orange grade, smooth steady camera
Kling O3 4K model variants
Kling O3 4K runs on Venice as 3 variants of the same underlying model — pick by what you're starting from: a written prompt, a still image, reference images, or an existing clip. Each variant is its own model id on the API; the generation quality is the same across the family.
| Variant | What it is | Clip lengths | Resolutions | Aspect ratios | Audio | Model ID |
|---|---|---|---|---|---|---|
| Text to Videoflagship | Generate a clip from a written prompt | 3s – 15s | — | 16:9, 9:16, 1:1 | kling-o3-4k-text-to-video | |
| Image to Video | Animate a still image into motion | 3s – 15s | — | — | kling-o3-4k-image-to-video | |
| Reference to Video | Keep a subject consistent using reference images | 3s – 15s | — | 16:9, 9:16, 1:1 | kling-o3-4k-reference-to-video |
Capability data comes straight from the Venice model API and refreshes with every catalog ingest. The specs and pricing on this page are captured from the flagship variant; pass the model id of the variant you want to the API.

What is Kling O3 4K good for?
- •Cinematic social ads and trailers with synchronized native audio.
- •Character-driven short scenes using reference-to-video to maintain subject identity across cuts.
- •Product and fashion motion visuals animated from still images.
- •Pre-visualization and multi-shot storyboarding for film and commercial planning.
- •Multilingual content with generated dialogue and environmental sound design.
Prompting tips
- •Use reference-to-video and upload multiple source images to lock character identity across camera cuts.
- •Draft at 3–5 seconds to test motion and composition cheaply, then extend to 15 seconds once the prompt is locked.
- •Describe camera language explicitly (e.g., 'wide establishing shot, then close-up') to leverage multi-shot control.
- •Include audio direction in your prompt if you need specific dialogue tone, sound effects, or music style.

Kling O3 4K is Kuaishou's flagship unified multimodal AI video model, launched in February 2026. It generates 4K clips up to 15 seconds from text, images, or reference subjects, with native audio, multi-shot storyboarding, and visual chain-of-thought reasoning.
On Venice you pay per clip, starting at $1.39 for a 3-second generation. Price scales with clip duration and resolution, so longer or higher-fidelity renders cost more. There is no subscription required.
You can try it on Venice with welcome credits; new accounts receive free credits to test generations. Beyond that, each clip is billed per use in credits.
No. Kling O3 4K is a proprietary closed model from Kuaishou. It cannot be self-hosted or fine-tuned. For open-weights video generation, Wan 2.7 is the closest alternative on Venice.
Yes. The variant kling-o3-4k-image-to-video animates a still image into motion, supporting the same 3–15 second durations and native audio as the text-to-video mode.
Venice runs Kling O3 4K under an anonymized privacy tier — your prompts are not stored, profiled, or used for training. Generations are processed without tying them to personal account history.
Kling O3 4K is built for maximum resolution output (4K). Kling O3 Pro targets higher-fidelity motion and artistic quality at a lower resolution tier. If you need 4K deliverables, use O3 4K; if you need pro-grade motion and can work at standard resolutions, O3 Pro may be more cost-effective.
It supports 3-second to 15-second clips in 16:9, 9:16, and 1:1 aspect ratios, with optional native audio on every generation.
Yes. It produces native audio including dialogue, environmental sound, and music, with lip-sync that matches character mouth movements to the generated audio track.
