Kling AI

Kling AI is a state-of-the-art video generation platform capable of producing high-fidelity cinematic content. It features advanced camera control, localized motion brush tools, and industry-leading temporal consistency for long-form narrative generation. Newer API tiers add native 4K-class pipelines (including O3-class routes on hosts such as fal.ai) so teams can aim for broadcast-ready masters without always chaining a separate upscaler.

Kling 4.0 is Kuaishou's next-generation Kling video model, announced September 28, 2026. It doubles the longest single generation to 30 seconds, continues a video across multiple shots up to 2 minutes, takes up to 15 references in text, image and video, and lets you pin up to 10 keyframes to control how a scene unfolds. Output goes up to 4K, with 10-bit HDR and a 21:9 ultra-wide ratio, plus stereo audio and more accurate lip sync. A lighter Kling 4.0 Flash went live the same day for Ultra Yearly subscribers only; Kling says the full Kling 4.0 is coming in October 2026.

Supports video generation up to 10 seconds with realistic physics, natural camera movements, and synchronized audio that matches the visual content.
