Boogu-Image-0.1-Basevs.PixArt-Sigma-XL-2-1024-MS

Which one is better?

In our own test both are on par. Neither is in the arena. Neither has an API price.

Test images

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

Boogu-Image-0.1-Base: Character and detail, first image from the fixed test run — Boogu-Image-0.1-Base8 out of 100

PixArt-Sigma-XL-2-1024-MS: Character and detail, first image from the fixed test run — PixArt-Sigma-XL-2-1024-MS27 out of 100

Result for “Character and detail”:PixArt-Sigma-XL-2-1024-MS slightly ahead

Prompt given to both modelsCreate a square cinematic full-body portrait of a fictional bicycle courier waiting under a transparent umbrella at a rainy tram stop in Hamburg at blue hour. She wears a mustard raincoat, navy trousers, red sneakers, a silver helmet, and carries a teal messenger bag. Keep both hands visible, render the bicycle correctly, use realistic wet-street reflections, and include no readable brand names.

What the rating looks at: Anatomy, clothing, and spatial consistency.

“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.
