Kling 4 AI Video Generator

Kling 4.0 is the latest generation of Kuaishou's Kling AI video model family, announced on September 28, 2026, with a full launch expected in October. This independent AI video generator platform, kling4.io, allows users to create cinematic video clips from text prompts, images, and reference clips. It is not affiliated with Kuaishou or Kling AI.

Key Features:

• Text to Video: Describe your desired scene in plain English, including subject, action, camera movement, lighting, and sound. Kling 4 transforms these prompts into cinematic clips within minutes, capable of following complex, multi-part prompts.
• Image to Video: Upload a product photo, portrait, or storyboard frame to serve as the initial visual. The model animates the scene while maintaining the integrity of faces, logos, and composition from your uploaded image.
• Multi-Keyframe Storyboards: Supports up to 10 keyframe images, allowing precise control over the sequence of events in a clip. Clips can be up to 30 seconds long natively.
• Omni Reference: Incorporates up to 15 reference items, including images, videos, voice references, and subjects, to lock specific elements like faces, outfits, or performance styles.
• Native Audio & Lip Sync: Generates two-channel stereo audio synchronized with the video, featuring lip sync capabilities across nine languages and various accents. It also renders on-screen text and emoji.
• Advanced Specifications: Offers clip lengths from 3 to 30 seconds, resolutions up to 4K with 10-bit HDR, up to 10 keyframes, and prompts up to 8,000 tokens.
• Flash Version: A lighter version of the model designed for faster, more frequent work, producing 3-20 second clips at 720p.
