About Kling O3 4K
Kling O3 4K is the native ultra-high-definition tier of Kuaishou's omni Kling model, priced at $1.05 per second. It keeps the Kling O3 modes, text to video, image to video, start and end frame and references to video, and raises the reference limit to 7 images.
Lengths run from 3 seconds to 15 seconds, with 16:9, 9:16 and 1:1 from text or references. Sound is optional and does not change the price. A typical generation takes about 4 min, against about 3 min for Kling O3 Pro.
