Kling 4.0 Complete Guide: Availability and Supported Kling Models

Service clarification — September 7, 2026: Kling 4.0 generation is not available on this website. We currently provide Kling 2.6 and Kling 3.0 Omni. Earlier claims on this page about verified Kling 4.0 features and free access were incorrect and have been withdrawn.

We run kling-4.ai, an independent platform, not affiliated with or endorsed by Kuaishou or Kling AI. This guide separates the Kling 4.0 topic from the services you can actually use here.

What is Kling 4.0?

Kling is Kuaishou's AI video model family. A future model name in our domain or editorial content does not mean that model is integrated, officially authorized, or available for purchase on this site. Consult official Kling announcements for release information and our actual model selector for available generation services.

The following are workflow options for the currently supported models, not confirmed Kling 4.0 specifications:

• Text and image direction. Describe the subject, action, camera and lighting; provide reference images where supported.
• Model-specific controls. Resolution, duration, references and audio depend on the selected model and input mode.
• Storyboard workflow. Use the available shot controls for supported configurations; do not assume longer durations than the workspace permits.
• Results vary. Reference images and detailed prompts can guide outputs but do not guarantee identity, motion or audio accuracy.

Creative gallery reference. We have not established this sample's exact model provenance; it is not proof of Kling 4.0 availability or guaranteed output.

Headline specs

The earlier figures for 120-second sequences, 80 references, 4K at 60fps and 99.8% stability were not substantiated. They are not current service specifications and should not be used to plan a purchase.

Check the selected model's reference limits before uploading. Use only material you have permission to process, and review outputs for unwanted changes before publishing.

What it actually looks like

These two existing gallery clips illustrate creative directions and prompting ideas. They are not verified Kling 4.0 outputs or benchmarks, and we do not claim that they are unedited model outputs.

Watch the product macros and lighting as visual references when writing your own shot list.

A continuous-take outfit transition is a useful creative brief; recreating it with the currently supported models may produce different results.

Both prompts are available word-for-word in the gallery on our homepage — hover any clip and hit "Prompt."

How to use supported Kling models with free credits

This is the part most guides bury under three affiliate links, so let's keep it simple. On kling-4.ai, guests can explicitly claim free credits from the account menu and spend them on any supported setup their balance covers. Here's the whole flow:

Step 1 — Describe your scene

Open the generator and type what you want: subject, action, camera move, lighting. You don't need a 3,000-character mega-prompt for your first run — "handheld close-up of a barista pouring latte art, warm morning window light, shallow depth of field" is plenty. If you're staring at a blank box, click "No ideas? click me" and grab one of the starter prompts.

Step 2 — (Optional) add a reference

Got a product shot, a character, a location? Attach it and the model will lock onto it. Skip this entirely for your first video if you just want to see what the model does.

Step 3 — Generate and download

Claim free credits from the account control, review the live credit quote, then generate. Renders take a few minutes depending on queue. Your video lands in your history where you can preview and download it. Free credits expire at the next UTC reset, so the account control always shows the current balance and countdown.

Kling 4.0 vs Kling 3.0 — should you care?

We cannot provide a verified 4.0-versus-3.0 benchmark because Kling 4.0 is not integrated here. Choose a currently available model based on your input needs, supported settings and quoted cost, not speculative future specifications.

For comparison criteria rather than an unverified winner, see Kling 4.0 vs Seedance 2.5.

FAQ

Is Kling 4.0 really free to use? No Kling 4.0 generation is offered here. Eligible visitors and signed-in users can claim free credits for supported models. Review the current plans and the live quote; buying credits does not unlock an unavailable model.

Can I use the videos commercially? Usage rights depend on the applicable model/provider terms and your local rules, including any AI disclosure requirements for ads.

Do I need prompt engineering skills? No, but they help a lot. Start simple, then steal structure from our prompt guide when you want multi-shot control.

Is this the official Kuaishou site? No. kling-4.ai is an independent platform — we provide hosted access to the Kling model series with our own generation pipeline, claimable free credits, and API documentation.

What about an API? API access is rolling out separately. Developer docs live here.

That's the whole picture. The fastest way to form an opinion is to claim today's free credits, open the generator, and type the weirdest shot you can think of. Worst case, you learn which settings fit your balance. Best case, you just found your new production pipeline.
