Kling 4.0 — Coming Soon to Viberot
Kling 4.0 is the next flagship model from Kuaishou's Kling team, following Kling 3.0. Kuaishou has announced longer clips, up to 4K output and more reference images per shot. It is not yet open to developers, so it can't be generated on Viberot yet — we'll switch it on as soon as the API is available. Until then, Kling 3.0 is ready to use.

What's the difference between Kling 4.0 and Kling 3.0?
