What is Kling 4.0?
Kling 4.0 is the newest AI video model from Kuaishou's Kling AI, available to everyone since October 15, 2026. It turns text, images, video clips and voice samples into 3 to 30 seconds of video with two-channel stereo sound, made in one pass.
Kuaishou offers it in its own Kling AI app. This site runs Kling 4.0 through a commercial API: write a prompt, start from a first frame (and optionally end on a last one), or give it reference images, clips and a voice, then download the MP4. Here it renders at 720P or 1080P; 4K, HDR, video editing and extension aren't offered on this site.
Kling is a trademark of Kuaishou Technology. Kling V4 AI is an independent service and is not affiliated with or endorsed by Kuaishou.

What's new in Kling 4.0
Longer takes, stereo sound and far more references than Kling 3.0, in one model for prompts, pictures and clips.
Up to 30 seconds in one take
Pick any length from 3 to 30 seconds. That's room for a whole scene — set-up, action and an ending — instead of a single beat.
Stereo sound with the picture
Dialogue, ambience, effects and music are generated with the video in two-channel stereo. Put spoken lines in quotes, in the language they should be spoken in.
Omni Reference
Up to 10 images, 5 clips (30 s combined) and 3 voice samples, 15 files in total. Name them @Image1, @Video1, @Audio1 and say what each one is for.
First and last frame
Start on your image and, if you like, end on another. The video takes the shape of the first frame.
Multi-shot by default
Kling 4.0 splits a longer prompt into shots and paces them itself. Write the beats in order, with rough timings, and it follows them.
720P or 1080P, four shapes
Render at 720P to try an idea and 1080P for the final. Text and reference renders come in 16:9, 9:16, 1:1 or ultrawide 21:9.

Kling 4.0 FAQ
Kling 4.0 is the newest video model from Kuaishou's Kling AI, available to everyone since October 15, 2026. It makes 3 to 30 seconds of video with stereo sound from text, images, video clips and voice samples. Kling V4 AI runs it in the browser, priced per second.
Yes. Kuaishou released Kling 4.0 to everyone on October 15, 2026, after early access to Kling 4.0 Flash began on September 28. You can use the full Kling 4.0 model right now in the generator at the top of this page.
No. Kling V4 AI is an independent site that runs Kling 4.0 through a commercial API. Kling is a trademark of Kuaishou Technology, and Kuaishou's own app is Kling AI at kling.ai.
Yes, once. A new account gets 110 free credits, enough for one 5-second Kling 4.0 video at 720P; they're valid for 30 days. After that, videos use one-time credit packs: 300 credits for $9.99. Failed renders cost nothing.
22 credits a second at 720P and 33 at 1080P, so a 5-second 720P clip is 110 credits. With a reference video you pay the output seconds plus the longer of the output or the video, at 14 credits a second at 720P (20 at 1080P). The form shows the exact total before you generate.
Clips up to 30 seconds instead of 15, up to 10 keyframes instead of a first and last frame, two-channel stereo sound instead of single-channel, a 21:9 ratio, more speech languages, and an Omni Reference that takes 15 assets (images, clips and voice) instead of 7. Our Kling 4.0 vs Kling 3.0 guide in the blog lists every change.
A faster, cheaper tier of Kling 4.0 in Kuaishou's own app: 3 to 20 seconds at 720p, from text, a first frame or Omni Reference, without first/last-frame control. Kling V4 AI runs the full Kling 4.0 model, not Flash.
Kuaishou's developer platform lists a Kling 4.0 API at about $0.14 a second for 720p and $0.21 for 1080p, rolling out as early access. It's meant for developers building their own app. Kling V4 AI is the no-code way in: type a prompt, press Generate and download the MP4.
3 to 30 seconds, in whole seconds. Kling 4.0 is multi-shot by default, so one long prompt can cover several shots. Extending a video past 30 seconds isn't offered here.
Not on this site. Kling's own app renders Kling 4.0 at 720p, 1080p and 4K, and lists 10-bit HDR as coming soon. Kling V4 AI offers 720P and 1080P.
Yes, always. Kling 4.0 generates dialogue, ambience, effects and music with the picture, in stereo. Put spoken lines in quotes and say who speaks; add "no background music" or "no subtitles" if you don't want them.
Yes. Choose Image, add a first frame (and optionally a last frame), and describe what happens. A last frame on its own isn't accepted. The video takes the shape of your first image.
Kling 4.0's way of following your files without using them as frames: up to 10 images, 5 video clips (3–30 s each, 30 s in total) and 3 voice clips of 5–30 s, 15 files in total. Name them @Image1, @Video1, @Audio1 in the prompt and say what each one is for. Audio sets a speaker's voice and needs at least one image or clip.
Not here yet. Kling 4.0 can edit footage in Kling's own app, and Kuaishou lists extension up to 2 minutes as coming soon. This site offers text, first/last frame and reference generation; a reference video guides a new clip but isn't edited.
Describe what we see and hear, not adjectives: subject and action, setting, camera move, light, then sound — spoken lines in quotes, plus ambience and music. For longer clips, list the beats with rough timings (0–5 s, 5–12 s…). Our prompt guide has examples.
Your credits go back to your balance automatically. Requests the provider rejects, for example for content, are not charged either.
Yes, the videos you make are yours to use, as long as your prompt and files don't infringe anyone's rights. See the terms for details.
They're used only to make your video and deleted 30 days later. Finished videos stay in your history until you delete them or your account.
