Is Kling 4.0 available now?

Yes. Kling 4.0 has been available since October 15, 2026 in Kling's creation workspace, through Kling's MCP server and command-line tool, and on third-party platforms. Features and parameters can differ by platform and account, so check the model selector and settings where you create.

The guide describes two creation entry points:

• Omni Reference: start with a written idea or use assets to direct appearance, actions, camera movement, and voice.
• Keyframes: place images at important moments to control how the visual sequence develops.

These entry points cannot be combined within a single generation task. Choose the workflow around the control your scene needs.

How to start using Kling 4.0 today

1. Open your Kling account, or another platform that offers Kling 4.0, and check the model and settings shown in the creation workspace.
2. Choose your workflow. Use Omni Reference for asset-based direction or Keyframes for predefined visual moments.
3. Write a concrete prompt. Describe the subject, scene, action, camera, and sound. The input limit is 8,000 tokens.
4. Set duration and framing. Omni Reference offers 3–30 seconds in one-second increments, with a 10-second default.
5. Review the result. Check identity, motion, timing, and audio before changing one instruction at a time.

Our how to use Kling 4.0 guide provides a broader walkthrough. On Kling4.tv, start from Kling AI text to video or image to video, depending on whether your idea needs an initial image. Kling 4.0 there is open to members on a paid plan or credit pack.

What is Kling 4.0 Flash?

Kling 4.0 Flash is the guide’s option for rapid creative iteration and short-form video. It supports clips up to 20 seconds at a maximum resolution of 720p. The guide says it does not support first-and-last-frame or multiple-keyframe workflows.

Choose the standard model when you need longer clips, higher resolutions, or keyframe control. The guide does not provide a measured speed comparison or a price table. Read our Kling 4.0 Flash guide for further context, or visit the Kling 4.0 overview.

What are the new Kling 4.0 features?

Beyond the Kling 4.0 Release Date, the official guide provides practical limits for planning a generation:

• Duration: 3–30 seconds per generation. A 30-second setting describes output length, not processing time.
• Resolution: 720p, 1080p and 4K; 10-bit HDR is marked as coming soon.
• Aspect ratios: 21:9, 16:9, 1:1, 9:16, and Auto. Omni Reference defaults to Auto.
• Prompt length: up to 8,000 tokens. This is a token limit, not a word count.
• Keyframes: up to 10 image inputs to guide important visual moments. See our Kling 4.0 keyframes guide.
• Omni Reference: up to 15 assets total, subject to individual input limits. Our Kling 4.0 Omni Reference guide explains asset roles.
• Audio: two-channel stereo, voice references, and improved lip synchronization, according to the guide.
• Editing: targeted changes to expressions, movement, camera position, backgrounds, and style while directing preservation of other content.

The reference limits are up to 10 images, five videos, seven elements, and three voice profiles. The seven-element allowance can include up to three video elements. These individual ceilings do not increase the overall 15-asset limit.

Reference videos, editing videos, and video elements share a quota of five clips and 30 seconds total. Reference clips must each be 3–30 seconds. An editing task can include one primary video within that shared allowance. Assign each asset a clear role, such as preserving a character’s appearance or borrowing camera pacing.

Audio input supports voice profiles only. You cannot upload background music or sound effects through that input; describe those requirements in the prompt for the model to generate. Audio-visual synchronization and Smart Storyboard are enabled by default, without separate toggles.

The guide lists Chinese, English, Japanese, Korean, Spanish, Portuguese, German, French, and Hindi. Accent and dialect examples include Beijing Mandarin, Taiwanese Mandarin, Northeastern Mandarin, Sichuan dialect, Cantonese, and American, British, and Indian English. It also describes multilingual text, emoji, and logo rendering.

For output resolution and HDR status, see our Kling 4.0 4K page.

How is Kling 4.0 different from Kling 4.0 Flash and Kling 3.0?

Kling's User Guide compares the standard model with Flash as follows.

When you compare models, use the same scene and instructions for each.

What should I check before a first generation?

Check the model, settings and credit estimate in the generator before you submit.

On Kling4.tv, new accounts receive 40 credits, enough to generate one video on the default model; Kling 4.0 itself needs a paid plan or credit pack. Start with one clear subject and action.

Can developers use Kling 4.0 through MCP or CLI?

Yes. Kling's MCP server and command-line tool support Kling 4.0. The Kling 4.0 API has been fully available since October 28, 2026, and the Kling 4.0 Flash API since November 4, 2026. The API outputs 720p and 1080p; 10-bit 4K is marked as coming soon.

See our Kling 4.0 API guide for setup and status.

Kling 4.0 Prompt Examples for 30-Second Videos

These shortened examples preserve the original creative directions. Treat timing as instructions to review in the output, not a guarantee of exact execution. The guide recommends concrete visual descriptions and adding only details that affect the result.

1. 30-second cinematic short film

Create a 30-second film about an elderly lighthouse keeper during a storm. Preserve clothing and geography.
0–6s: Approach the lighthouse at dusk; waves sound on the left.
6–12s: Follow the keeper upstairs with a brass lantern.
12–18s: The beacon fails; show hands reconnecting a cable.
18–24s: The keeper whispers, “Someone is still out there.” Warm light returns.
24–30s: Pull back as a distant boat answers with two lights.

Why it works: the prompt specifies a setup, problem, resolution, and restrained audio direction.

2. AAA game-style footage

Create a 30-second third-person action sequence featuring an original armored scout in a ruined aqueduct.
0–6s: Track the scout running over wet stone.
6–12s: A stone guardian blocks the route; the scout slides beneath its arm.
12–18s: Follow a chain swing to a neighboring platform.
18–24s: Show a dodge and spear strike.
24–30s: Follow the scout escaping toward sunrise. Emphasize footfalls, armor movement, and falling masonry.

Why it works: each beat describes visible action. Use references for character design or choose Keyframes to fix important compositions.

3. Stop-motion animation

Create a 30-second stop-motion scene about a clay gardener rescuing a fallen star. Preserve fingerprints, felt textures, and gently stepped movement.
0–6s: A star falls into a felt cabbage patch.
6–12s: The gardener approaches with a thimble watering can.
12–18s: Wrap the star in yellow fabric.
18–24s: Climb a spool staircase to a moon-shaped cradle.
24–30s: Pull back as the star brightens. Add soft bells and fabric rustling.

Why it works: material details make the style concrete; the guide explicitly includes felt among supported visual styles.
