FLUX.1 Kontext [max]vs.MOSS-Image-SFT
Which one is better?
In our own test both are on par. Neither is in the arena. Neither has an API price.
Same prompt, two images
Same task, the first image of each. The task with the biggest difference is preselected.
![FLUX.1 Kontext [max]: Product photography, first image from the fixed test run](/_astro-img/5fdb0754fb415677/1024.webp)

Result for “Product photography”:MOSS-Image-SFT ahead
What the rating looks at: Materials, reflections, and fine details.
“Ahead”: better in all three rating rounds. “Slightly ahead”: a higher value, but not in every round.
Test protocol of the images
Both models receive the same archived prompt in exactly one request, and the first result counts. 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.
