Best model: Flux or SDXL. Flux is better when the logo needs legible lettering; SDXL is fine for pure marks.
Left to its own devices a diffusion model makes logos that are far too detailed — gradients, textures, 3D bevels, drop shadows. Good logo prompting is mostly subtraction: ask explicitly for flat color, simple geometric shapes, minimal, vector style, and a plain background, and negative-prompt the clutter.
Treat the result as a concept, not a deliverable — generate a mark you like, then rebuild it cleanly in real vector software. For exploration, the model is a fast idea machine.
Example prompts
Hit Open in Builder to drop any of these straight into the workspace, then tweak, weight and generate.
minimalist flat vector logo of a fox head, simple geometric shapes, two flat colors, bold clean lines, negative space, centered, plain white background, modern, professional, high contrast
Negative: gradient, 3d, bevel, drop shadow, realistic, photographic, texture, cluttered, detailed, busy, text, watermark
flat design app icon, abstract geometric mark, rounded square, two-tone flat color, subtle depth, centered, plain background, clean, modern, minimal
Negative: realistic, photo, 3d render, gradient mesh, noisy, cluttered, text, watermark, lowres
Tips that actually move the needle
- Say "flat", "vector style", "minimal" and "simple geometric shapes" — and mean it. Under-describe rather than over-describe.
- Ask for a "plain white background" so the mark is easy to cut out and iterate on.
- Heavily negative-prompt the clutter: "gradient, 3d, bevel, drop shadow, texture, busy, photographic".
- Limit the palette in words ("two flat colors", "two-tone") — unconstrained color is what makes AI logos look amateur.
- For lettering, prefer Flux and put the exact word in quotes; expect to redraw type in real software regardless.
Frequently asked questions
Can AI make a usable logo?▾
Use it for concepts and marks, not final files. Diffusion output is raster and inconsistent at small sizes — generate ideas, then rebuild the chosen mark cleanly in vector software.
How do I stop AI logos from being cluttered and 3D?▾
Explicitly demand flat, minimal, vector style with simple shapes and a plain background, and push "gradient, 3d, bevel, drop shadow, texture, busy" into the negative prompt.
