Kling (by Kuaishou) is a video-first model family with text-to-video, image-to-video, start/end-frame control, motion control, talking avatars, and native audio. Kling V3 is the flagship: the only version with multi-shot storyboards and native 4K (3–15s), with Kling V3 Turbo as a faster variant. The lineup also spans image generation and a TTS / video-to-audio side.
