FLUX.2 Provs.Stable Diffusion XL 1.0

Which one is better?

In our own test, FLUX.2 Pro leads. Stable Diffusion XL 1.0 has no arena rating yet. Stable Diffusion XL 1.0 has no API price.

Test images

Same task, the first image of each. The task with the biggest difference is preselected.

FLUX.2 Pro: Typography and layout, first image from the fixed test run
FLUX.2 Pro69 out of 100
Stable Diffusion XL 1.0: Typography and layout, first image from the fixed test run
Stable Diffusion XL 1.05 out of 100

Result for “Typography and layout”:FLUX.2 Pro ahead

Prompt given to both modelsCreate a square editorial poster for an imaginary night train called MONDFALTER. Show the exact German headline MONDFALTER and the exact subline BERLIN NACH LISSABON. Use a restrained midnight-blue and warm-cream palette, one stylized moth, strong Swiss-grid typography, generous negative space, and no additional words or logos.

What the rating looks at: Legible text, hierarchy, and composition.

“Ahead”: better in all three rating rounds. “Slightly ahead”: a higher value, but not in every round.

Test protocol of the images

Each test attempt uses the same archived prompt and one request. The first output of that attempt counts. Repeats after technical test failures are disclosed for the affected images. Files are normalized to 1,024 × 1,024 pixels without cropping. Provider resolution, randomness, quality tier and prompt processing can still differ. The images are a practical visual test, not a reconstruction of the arena configuration.
