This guide walks you through exactly where to click, how to choose models, how to insert references, and how to build UI moodboards.
Perfect for designers, founders, and beginners building apps and websites.
Where to Find the UI / UX Models in Leonardo AI
Leonardo does not have a section labeled “UI/UX,” so beginners often get confused.
Here’s what you actually need to do:
Step 1 — Go to “Models”
In the left sidebar, click Models → Image.
Step 2 — Choose a Model Optimized for UI/UX
Use these recommended models:
| Model | Best For | Why Use It |
|---|---|---|
| Flux 1.1 Pro | Clean UI, dashboards, mobile apps | Very stable layout structure and typography |
| Nero Banna Pro | Modern UI concepts, gradients | Crisp geometry + soft shadows |
| Photon 1.0 | Web design, hero sections | Balanced visuals + minimal distortion |
| GPT-Image-1 | Wireframes & simple layouts | Great for low-detail UI structure |
| Phoenix 3.0 | Landing pages & marketing UI | Strong composition + visual clarity |
Tip: For UI design, avoid highly artistic models like “Lucid” or “Phoenix Hyperreal” — they create too much noise.
