Pick a Kling 4.0 Tier and Settings

Choose Flash (free to try), Flash HD (1080p with audio), Standard or Pro for higher fidelity with native audio, or 4K for maximum resolution, then set aspect ratio and duration.

Capabilities

What Kling 4.0 Does for Your Next Clip

From native 4K to dialogue in the same pass: the four jobs creators bring to it, and the tier that handles each one.

Cinematic 4K from a text prompt

Describe the scene, camera move, lighting, and mood, and the model renders it as cinematic video, up to native 3840×2160 in 4K mode, with fine texture and depth of field holding up through fast motion.

  • Standard, Pro, and 4K tiers for final-quality renders
  • Six aspect ratios: 16:9, 9:16, 4:3, 3:4, 21:9, and 1:1
  • Clips up to 15 seconds

Multi-shot scenes with the same characters

It carries faces, clothing, and proportions across cuts and camera angles, so a sequence reads as one story instead of a stack of unrelated shots.

  • Character identity held from shot to shot
  • Setting and style stay consistent between cuts

Animate a photo with start and end frames

Upload a still and the model animates it with natural motion. On Standard, Pro, and 4K, add an end frame and decide exactly where the shot lands.

  • Image-to-video on every tier, including Flash
  • Start and end frames on Standard, Pro, and 4K

Dialogue, sound, and music in the same pass

Flash HD, Standard, and Pro generate synchronized audio with the picture: dialogue, ambient sound, foley, and music, so the clip is ready to post without a separate edit.

  • Flash HD: 1080p with audio at 5 or 10 seconds
  • Standard and Pro: audio billed per second of video

What Creators Say About Kling 4.0

Verbatim posts from creators who got early access to Kuaishou's Kling 4.0 and 4.0 Flash on September 28, 2026. Each links to the original post.

I only gave it a few reference images and asked it to create a consistent, artistic video. I tried the exact same prompt with Kling 3.0 before, but 4.0 Flash delivered an absolutely PERFECT result.

Kuaishou announced Kling 4.0 on September 28, 2026, with the full release scheduled for October; the lighter 4.0 Flash opened the same day, but only to Kling's Ultra Yearly subscribers. The announced model reaches 30-second single generations, takes up to 10 keyframes, combines up to 10 images, 5 videos, and 7 subjects as references in one task, accepts 8,000-token prompts, and adds stereo audio; 10-bit HDR output at 4K and 1080p and extending a clip to about 2 minutes are listed as coming soon. You need neither an annual plan nor a waitlist to create here: the tier here renders 4K, native audio, and multi-shot sequences today, and the 100 credits you get at signup cover your first 5-second Kling 4.0 Flash clip.

Kling 4.0 Flash is the lighter, lower-cost member of the 4.0 lineup, built for fast, high-volume generation. On Kling's own app it went live on September 28, 2026 for Ultra Yearly subscribers only, ahead of the full October release. On kling4.co, Flash is the free way in: a flat 75 credits for a 5-second clip, covered by the 100 signup credits, and Flash HD adds 1080p with audio.

There is a free way in. Every new account gets 100 credits at signup — no card, no subscription — and a 5-second Flash clip is a flat 75 credits, so your first video is covered by the signup grant. Those credits never expire. When a shot needs 1080p with audio, native 4K, or clips beyond 5 seconds, step up to Flash HD, Standard, Pro, or 4K and pay only for what you render.

Flash is a flat 75 credits per 5-second clip, and Flash HD is 95 for a 5-second 1080p clip with audio (185 for 10 seconds). Standard runs about 40 credits per second silent, so a 5-second clip is 200 credits and 290 with native audio. Pro with audio comes to 375 credits for 5 seconds, and native 4K is also 375. The generator shows the exact figure before you create, and a failed generation is refunded.

Six aspect ratios: 16:9, 9:16, 4:3, 3:4, 21:9, and 1:1 — so a single prompt covers YouTube, TikTok and Reels verticals, square social posts, and cinematic widescreen. Clip length runs to 15 seconds: Flash renders 5-second clips, Flash HD renders 5 or 10, and Standard, Pro, and 4K handle the longer multi-shot sequences.
