FAQ

About Kling O1 Image API

It generates still images from a prompt with optional reference images and IMAGE-only element definitions, 1K or 2K resolution, and explicit aspect presets.

You pick from 16:9, 9:16, 1:1, 4:3, 3:4, 3:2, 2:3, and 21:9. There is no Auto setting in this form.

Reference images and elements share a single pool capped at 10 images.

Choose Omni Image when you need Auto aspect or 4K. Stay on O1 Image when your pipeline already uses these eight aspects and 1K or 2K output.
