A user posts a screenshot claiming two Kling 4.0 model entries have appeared: Kling 4.0 Preview and Kling 4.0 Flash Preview.

A user who applied for the Kling 4.0 beta says its quality reportedly falls between Seedance 2.0 and 2.5, with TOC access on the 28th and full rollout on October 13.

Commenter says Kling 4.0 is unconfirmed but 30s generation may become the default given Seedance 2.5 and Wan 3.0, and Kling's live-action texture could break Seedance 2.5's dominance.

A user says no model matches February's Seedance 2.0, as rivals fail at action scenes or have poor audio engines, and hopes Kling 4 competes.

Leaked testing details for Kling 4 include 30-second generations with up to 10 keyframes, Omni reference with up to 15 references including 3 voices, and an experimental 2-minute video mode.

A teaser says Kling 4.0 will generate videos up to 30 seconds, support Omni Reference with up to 15 multimodal references, and reach 4K resolution.

A longtime Kling user relays leaked 4.0 specs including Preview, Flash and Image 4.0, 30-second generations, 15 reference elements, 1080p, 60-second extensions and a 120-second experimental mode, while questioning the three voice references.

Leaked settings list Kling 4.0 at 3–30s with 720p/1080p and up to 10 keyframes, an experimental 3–120s long-video mode, and Flash at 3–20s locked to 720p, plus reference and API billing details.

A user who started with Kling 2.0 says Kling lost ground to Seedance and MiniMax, and wonders if Kling 4.0 can challenge current SOTA video models.
