About
Kling 2.1 was released at the end of May 2025 by Kuaishou, following Kling 2.0's April debut. It ships in Standard (720p) and High Quality (1080p) modes plus a premium Master Edition with enhanced motion performance and semantic responsiveness, built on 3D spatiotemporal attention and a proprietary 3D VAE.
Kling AI reached a $100M annualized revenue run rate within ten months of its June 2024 launch, serving over 10,000 corporate clients via API, and competes directly with Google's Veo 3 in cinematic text-to-video. Access is through Kling's subscription platform and API; the model itself is closed.
