Kling AI is an advanced AI video generation platform developed by Kuaishou Technology, capable of producing photorealistic videos from text prompts, images, or reference videos. Since its global launch in mid-2024, Kling has grown to over 12 million monthly active users and approximately $240 million in annual recurring revenue, positioning it as one of the top AI video tools worldwide. Kling 3.0 (released February 2026) introduced native 4K generation at 3840x2160 resolution, Chain-of-Thought reasoning for improved scene coherence, multi-shot scene logic with consistent characters across cuts, and 60fps output for broadcast-quality footage. A standout capability is motion transfer: users upload a reference video and Kling extracts its motion pattern, applying it to an entirely different subject — a feature that went viral in early 2026. Kling also supports up to 3-minute video clips, the longest consumer-priced duration of any major AI video generator, along with precise camera motion controls (push, pull, pan, orbit) and exceptional rendering of physical phenomena like water, smoke, and fabric movement. The platform includes Avatar 2.0 for consistent AI avatars and a Kling API for developer integrations.
