Kling 4.0 Brings Professional-Grade Video Generation to 30 Seconds with Omni Reference Control

Kuaishou's Kling 4.0 video model is now widely available with doubled clip length, expanded reference capabilities, and production-quality features that challenge competitors in AI video synthesis. The model, fully launched on October 15, 2026, extends native generation to 30 seconds—double Kling 3.0's 15-second maximum—while introducing Omni Reference, a system that combines up to 15 reference assets including images, videos, subjects, and voice to guide consistent character and product appearance across sequences.
