Model Details

Model Details

Uni-1 is the standard tier of the Uni-1 family: it generates a single, high-quality image from a text prompt quickly and cost-effectively. It carries the full Uni-1 feature set — manga styling, web-grounded references, and reference-guided generation — and is the right default when you want a polished result without the higher cost of the Max tier. For maximum detail and the strongest prompt adherence on hero stills, reach for `luma/uni-1-max` instead.

## Features - Single high-quality output generated quickly and at low cost - Optional manga styling for line-art and comic aesthetics - Web-grounded generation that can consult the web for references when enabled - Reference-guided generation from up to nine images - Flexible framing via aspect_ratio, with PNG or JPEG output

## What it's good at - Fast, affordable single images for iteration and everyday generation - Faithful rendering of clear, specific prompts - Stylized illustration when manga mode is selected

## Style The `style` field selects the rendering aesthetic: - `auto` (default) — picks the most fitting photorealistic or illustrative style for your prompt. - `manga` — black-and-white manga / comic line-art. Choose this for paneled illustration, inked characters, or graphic-novel looks.

## Web-grounded references Set `enable_web_search` to let the model consult the web for visual references while generating — useful when your prompt names real, recent, or niche subjects it should depict accurately. Leave it off for faster, self-contained generation.

## Reference-guided generation Pass up to nine image URLs in `reference_image_urls` to steer composition, subject, or style toward your own references; the model blends their guidance with your prompt.

## Tips - Write clear, specific prompts to get the most out of each generation. - Use manga only when you want line-art; auto covers most photoreal needs. - Step up to `luma/uni-1-max` when you need the highest fidelity on a single hero image.

## Limitations - Produces one image per request (no batch variations).

To run via the ModelRunner JavaScript client: ```js import { modelrunner } from "@modelrunner/client";

const result = await modelrunner.subscribe("luma/uni-1", { input: { prompt: "a lighthouse on a cliff at golden hour, dramatic sky", aspect_ratio: "16:9", style: "auto", }, }); ```
