Kling 3.0 Omni Image API

Unifically: one endpoint, one API key, USD billing.

What is Kling 3.0 Omni Image?

Kling 3.0 Omni Image is the image generation route under Kling 3.0 Omni. It is one of the more capable reference-driven image models on the platform: up to 10 reference images, nine aspect ratios (Auto plus eight named ratios from square through 21:9), and a 1K, 2K, or 4K output mode. The reference syntax (@image_1, @image_2) matches the Kling 3.0 Omni video endpoints, so you can mock a composition in image, then animate the same prompt and references in video without changing the reference shape. Use it when the brief needs heavy reference handling, mixed aspect ratios across formats, or 4K stills straight out of the endpoint.

Key features of Kling 3.0 Omni Image

Four features define what production teams build with Omni Image.

Up to 10 reference images per call

Pass image_urls (max 10) and reference them in the prompt as @image_1 through @image_10. Useful for brand campaigns where the brief locks character, product, environment, and palette references.

1K, 2K, or 4K output

Pick the resolution at the end of the cycle. 1K for fast iteration, 2K for most delivery, 4K for hero stills and print.

Auto aspect ratio plus eight named ratios

Auto lets the model choose the output ratio based on your references. The eight explicit options (1:1, 16:9, 9:16, 4:3, 3:4, 3:2, 2:3, 21:9) cover every standard placement.

Reference shape matches Kling 3.0 Omni video

The same @image_1 syntax works in the Omni video endpoints, so a still composition you mock here can be animated in video with the same prompt and references.

Best for

Heavy-reference image work

Up to 10 reference images per call. Useful for brand campaigns with many fixed visual elements.

Cross-format campaign packs

Auto aspect plus the same prompt produces matched-look outputs across square, vertical, and widescreen.

Mock-then-animate workflows

Reference syntax matches Kling 3.0 Omni video. Mock in image, animate the same prompt and references in video.

4K hero stills

Single deliverable in 4K straight from the endpoint. Useful for print, billboards, and large-format hero placements.

Variant boards from one prompt

Different aspect ratios from the same prompt and references. Useful for moodboards and design exploration.

Use cases

Mock a campaign hero composition with 10 reference images locked (character, product, environment, brand palette), then animate the same prompt and references in Kling 3.0 Omni video without rewriting the call. Generate a cross-format pack from one prompt by running it once at Auto aspect and once each at 16:9, 9:16, and 1:1. Render a 4K hero still for a print run by setting resolution to 4K on the chosen prompt. Run a moodboard pass for a brand pitch by holding the references constant and varying only the aspect ratio across the boards.
