Kling

Kling (可灵) is Kuaishou’s flagship AI video generation model, creating cinematic text-to-video and image-to-video clips with strong motion realism.

Overview

Kling burst onto the global AI video scene as one of the first openly accessible models that could rival Sora-class quality, and it has kept a fast release cadence since. It generates videos up to several minutes long from text or image prompts, with capabilities like lip-synced talking humans, motion brush control, start/end-frame conditioning and video extension. Trained inside Kuaishou — a short-video company — Kling’s outputs are tuned for the aesthetics and pacing of social video. The web studio and app offer consumer-friendly creation, while APIs serve developers and businesses.

Filmmakers use image-to-video with start and end frames to direct specific shots, while motion brush control adds targeted movement to static elements. The professional mode raises resolution and duration for ad-grade output, and lip-sync generation turns still portraits into speaking characters for storytelling. For studios, API access means generation slots can be embedded in production pipelines alongside rendering farms.

Who Is It For

It serves filmmakers, advertisers, content creators and game studios producing short-form and commercial video, plus developers building video features on top of generative models.

A creative studio storyboards a short film, then uses image-to-video with start and end frames to execute precise camera moves on generated shots. Motion brush animates specific elements — a hand gesture, fabric movement — while extension features carry scenes past the initial duration limit. Lip-sync turns still portraits into narrating characters, and API access slots generation into the studio’s existing pipeline.
