Luma Uni 1 API for Reasoning-Driven Image Generation
The Luma Uni 1 API delivers Luma's first unified reasoning image model through Atlas Cloud, covering text-to-image, directable editing, and reference generation from up to 9 images. Uni-1 reasons through a prompt instead of matching keywords, so scenes complete with common-sense spatial logic and less of an AI look, output at 2048px across nine aspect ratios. Reach all four models through one Atlas Cloud key with pay-as-you-go pricing from $0.04 per image and no waitlist. Start building today.
Atlas Cloud (operated by Atlas Cloud AI LLC) provides access to third-party AI models developed and owned by their respective providers. Atlas Cloud does not own these models, and all model names, product names, and trademarks belong to their respective owners.

One Luma Uni 1 API, Four Models
Compare model versions side by side — resolution, speed, pricing, and capabilities at a glance to find the best option for your project.
| Modality | Description |
|---|---|
| Luma Uni 1 Text-to-Image | Turn a text prompt into a 2048px image across nine aspect ratios, with Uni-1's reasoning and cultural awareness built in. The standard tier for everyday text-to-image at the lowest price on the page. |
| Luma Uni 1 Edit | Send an image with an instruction, or up to nine reference images, and get highly directable edits that change only what you describe. Source-grounded controls keep the rest of the frame consistent. |
| Luma Uni 1 Max Text-to-Image | The Max tier for text-to-image, for work that calls for Uni-1's highest output quality. Same prompt-to-image flow, premium tier. |
| Luma Uni 1 Max Edit | The Max tier for editing and multi-reference generation, for the most demanding directable edits and reference composites. Same edit and up-to-nine-reference workflow, premium tier. |
Luma Uni 1: Built to Reason, Direct, and Stay in Style
Combining advanced models with Atlas Cloud's GPU-accelerated platform delivers unmatched speed, scalability, and creative control for image and video generation.
Reasoning, Not Keyword Matching
Uni-1 reasons through your prompt rather than matching keywords, drawing on broad world knowledge and a close read of your input. Scenes complete with common-sense logic, spatial reasoning, and plausibility-driven transformation.
Directable by Design
Give precise direction over camera angles, lighting, and composition, and the model follows it. Control stays with you instead of being left to a lucky sample.
Up to 9 Reference Images
Generate a new image from as many as nine references with source-grounded controls, so characters, styles, and objects carry across. Reference-based generation keeps outputs anchored to what you supply.
Culture-Aware Output
Uni-1 generates across aesthetics, memes, and manga with real cultural awareness. Manga and webtoon generation and style transfer rank among its best-in-class strengths.
Top-Ranked in Human Preference —
In human preference Elo, Uni-1 ranks first for Overall, Style & Editing, and Reference-Based Generation, and second in Text-to-Image. Directable edits change exactly what you describe and leave the rest intact.
Less of an AI Look
The unified architecture enables flexible prompting and highly diverse outputs with less of an AI look. Cinematic image generation and novel view synthesis are among its strongest cases.
Where Luma Uni-1's Reasoning Pays Off
Discover practical use cases and workflows you can build with this model family — from content creation and automation to production-grade applications.
Cinematic Key Art
Cinematic image generation is a best-in-class strength, and directable control over camera and lighting turns a written brief into a composed hero frame.
Manga and Webtoon Panels
Culture-aware generation handles manga and webtoon styles that generic models flatten, holding line, tone, and paneling conventions true to the form.
Character-Consistent Series
With up to nine references and top-ranked reference-based generation, a character or product stays recognizable across a full set of images.
Directed Photo Edits
Send an image and an instruction, and Uni-1 changes only what you describe while the rest of the frame stays intact, no full regeneration required.
Style Transfer and Restyling
Style transfer and style reference are core strengths, so one look can be carried across a batch of images with source-grounded control.
Novel View Synthesis
Spatial reasoning lets Uni-1 render a subject from a new angle, useful for product turntables and set extensions that need plausible geometry.

FAQ
Luma Uni 1 is Luma's first unified understanding and generation model, a multimodal reasoning model that generates pixels. It handles text-to-image, directable editing, and reference-based generation, reasoning through a prompt rather than matching keywords.
Yes. All four Luma Uni 1 models are live on Atlas Cloud now, reachable through one API key with pay-as-you-go pricing. Luma's own API access is waitlisted, so Atlas gives you a way to build on Uni-1 today without waiting.
Atlas Cloud offers each modality in two tiers: standard Luma Uni 1 and the higher Max tier, at $0.04 versus $0.10 per image for text-to-image, and $0.043 versus $0.103 for editing. Both share the same capabilities, with Max positioned as the premium-quality tier.
Uni-1 can generate an output image using up to nine reference images, with source-grounded controls that keep characters, objects, and styles anchored to what you provide.
Uni-1 outputs 2048px images across nine aspect ratios: 3:1, 2:1, 16:9, 3:2, 1:1, 2:3, 9:16, 1:2, and 1:3.
Yes. Atlas Cloud unifies all four models, standard and Max, text-to-image and edit, behind a single API key, so you can switch models by name without a separate account or setup.
