Official examples from the model vendor: Kuaishou.

Kling 3.0 is Kuaishou's February 2026 video model. It handles text-to-video and image-to-video with an optional first and last frame, 3 to 15 seconds, in 16:9, 9:16 or 1:1. Resolution tiers are std (720p), pro (1080p) and 4K. Optional native audio covers dialogue, lip sync and ambient sound. Prompts go up to 2,500 characters. Kuaishou's multi-shot mode and @-elements are not available on Jantaris yet; instead, describe several shots in one prompt ("Shot 1: ..., Shot 2: ...").

Best for

  • Transitions from a first to a last frame
  • Talking characters with lip-synced dialogue
  • Product shots animated from a packshot
  • 4K social and ad content

Prompting tips

  • Put spoken lines in quotes and say who speaks and in what voice.
  • For a transition, send the first frame in image_url and the last in end_image_url, then describe the move between them.
  • Audio is off by default; set generate_audio: true for dialogue and ambience.
  • With images attached, the aspect ratio follows the image.
  • For several shots in one clip, list them in order: "Shot 1: ..., Shot 2: ...".
  • To copy motion from your own video onto a character, use Motion Control, covered in AI motion control for dance videos.
