FLUX.2 Provs.SenseNova U1.5 Lite
Which one is better?
In our own test both are on par. SenseNova U1.5 Lite has no arena rating yet. SenseNova U1.5 Lite has no API price.
Test images
Same task, the first image of each. The task with the biggest difference is preselected.
Result for “Character and detail”:FLUX.2 Pro ahead
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.
