Kling 4.0 is the text-to-video entry point to Kuaishou's fourth-generation Kling family, released in October 2026 alongside its image-conditioned sibling Kling 4.0 and the reference-conditioned Kling 4.0 R2V. It takes a written prompt and returns a generated clip, with no source image or reference asset required.

Within this catalog it supersedes the 3.0-generation text-to-video endpoints, including Kling V3 Pro, Kling V3 Standard, Kling V3 Turbo Pro and the higher-resolution Kling V3 4K, as well as the parallel O-series variants such as Kling O3 Pro and Kling O3 4K. Those earlier tiers remain listed, and the 4K-labelled variants are still the explicit high-resolution options in the lineup.

Clip length, resolution and control options are not documented in this catalog; consult the official Kling API documentation for current limits. The same applies to audio generation, keyframe control and reference-asset handling for this generation.

The model is developed by Kuaishou. The catalog describes the Kling family as aimed at cinematic quality, human motion and editorial scenes, which positions this text-to-video endpoint toward narrative and character-driven shots rather than purely abstract or motion-graphics output.
