Kling 4.0 Announced

Kuaishou announced Kling 4.0 for October and switched on Kling 4.0 Flash the same day for Ultra yearly subscribers. The spec sheet reads like a list of everything filmmakers had been working around: native 30-second generation, up to 10 keyframes in a clip, up to 15 multimodal references in Omni Reference, 4K output with 10-bit HDR, stereo audio with tighter lip sync, video extension, and dialogue in multiple languages, accents and dialects.

Nearly eight months after Kling 3.0, the version number marks a convergence more than a leap. Thirty-second takes matched Wan 3.0, keyframe direction followed Luma Ray3.2, and HDR output followed Ray3 and Runway Ruby. By the fall of 2026 the leading models were competing on the same checklist.
