What is Kling 4.0?

Kling 4.0 is a browser-based AI video generation platform for creating clips from text prompts, uploaded images, and reference material. Operated through Kling40.app, it is an independent service, not affiliated with or endorsed by Kuaishou or Kling AI. It offers multiple video models for projects such as product ads, cinematic scenes, creator-style videos, and social content.

Users enter a prompt or upload an image, choose a model and output settings, then preview and download the result. The full Kling 4.0 option supports clips from 3 to 30 seconds, up to 10 keyframes, and combinations of up to 10 reference images and five reference videos. Additional capabilities include output up to 4K, synchronized stereo audio, and targeted edits to subjects, motion, backgrounds, and camera direction. Available settings depend on the selected model and mode.

Generation uses credits, with the cost displayed before submission and determined by settings such as duration and resolution. Eligible accounts receive daily free credits. Paid subscriptions add monthly credit allowances, priority generation, watermark-free downloads, and commercial use.
