FAQ

About Kling 3.0 Omni Image API

It generates images from text with optional reference images and IMAGE-only element definitions. You choose resolution up to 4K and aspect ratio including Auto.

Aspect ratios include Auto and eight named ratios from square through ultra-wide. Output resolution can be 1K, 2K, or 4K depending on your access tier.

Reference images and elements share one pool of up to 10 images total across the fields, matching the playground and docs.

Omni Image adds Auto aspect ratio and optional 4K output while keeping IMAGE-only elements. O1 Image uses fixed aspect presets with no Auto option and 1K or 2K resolution in the playground.
