Kling O3 vs Kling 3.0
What is the difference between Kling O3 and Kling 3.0?
Kling 3.0 is Kling's standard generator with separate nodes for text-to-video, first/last frame and motion control. Kling O3 is the "omni" model: one node that takes several reference images and can build multi-shot sequences, plus dedicated nodes for editing and restyling footage. Per run they start at the same price in OTOY Studio.

How to choose
Quality is a matter of taste and the shot, so the honest answer is to run the same prompt through each model and look. That's the main reason to use them in one place: in OTOY Studio you can wire one prompt and one set of reference images into all 2 models on the same canvas, run them side by side, and keep the winner. The comparison nodes let you view the results next to each other.
