Luma Uni-1: the image model that thinks before it creates
Luma Uni-1 is a multimodal reasoning model that understands your intention before generating a single pixel. Ranked #1 in human preference for overall quality, style, and reference-based generation — it doesn't just follow prompts, it reasons through them. Available on Picsart AI Playground.

What is Luma Uni-1?
Luma Uni-1 is a decoder-only autoregressive transformer that generates images through structured reasoning — the same token-by-token approach used by large language models. Unlike diffusion models that denoise random noise, Uni-1 decomposes your instructions, resolves constraints, and plans composition before rendering. The result is images that match what you actually meant, not just what you typed.
Built by Luma Labs, Uni-1 supports up to 9 reference images with assignable roles (style, character, composition, lighting, texture, mood), 76+ art styles, and multilingual text rendering including non-Latin scripts. It generates at 2K resolution across 9 aspect ratios.
How Luma Uni-1 reasons before it generates
Luma Uni-1 is available on Picsart AI Playground, giving you access to its reasoning-first generation alongside 90+ other models. Use Uni-1 when you need precise instruction following, complex scene composition, or reference-guided generation that maintains identity across images. Switch between Uni-1 and models like Flux 2 Pro, GPT Image 1.5, or Nano Banana 2 — all from one prompt.
