GPT Image 2vs.MOSS-Image-SFT

Which one is better?

In our own test, GPT Image 2 leads. MOSS-Image-SFT has no arena rating yet. MOSS-Image-SFT has no API price.

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

GPT Image 2: Character and detail, first image from the fixed test run — GPT Image 261 out of 100

MOSS-Image-SFT: Character and detail, first image from the fixed test run — MOSS-Image-SFT17 out of 100

Result for “Character and detail”:GPT Image 2 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

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.
