Kling 4.0
Early access: 4.0 Flash for Ultra yearly members only. Full model promised for October.
Kling 4.0 is built for directing a scene, not rolling the dice on a prompt. The full model promises 30-second clips at up to 4K with stereo sound, up to 10 keyframes to pin the story beats, and up to 15 references (images, clips, characters, voices) to keep a face or a product the same from shot to shot. You can also edit an existing clip without regenerating it. What you can actually use today is smaller: the Flash version, 720p and up to 20 seconds, open since September 28 only to Ultra yearly subscribers.
- What’s new
- Announced September 28, 2026: single clips go from 15 to 30 seconds, with keyframes, references and native stereo audio.
- Best for
- Long, multi-shot scenes you direct beat by beat
- Where
- kling.ai web and app. Kling 3.x is also on the API and inside Adobe Firefly, Runway and Higgsfield.
The catch. Almost nobody can use it yet. Flash is 720p and has no keyframes, and it’s gated to the top yearly plan until October. One news report says the full model launched September 28. It didn’t. Source ↗
The one to watch. Wait for October unless you already pay for Ultra.
