Qwen Image 3.0 Provs.Chroma1-Flash

Which one is better?

In our own test, Qwen Image 3.0 Pro leads. 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.

Qwen Image 3.0 Pro: Product photography, first image from the fixed test run — Qwen Image 3.0 Pro71 out of 100

Chroma1-Flash: Product photography, first image from the fixed test run — Chroma1-Flash16 out of 100

Result for “Product photography”:Qwen Image 3.0 Pro ahead

Prompt given to both modelsCreate a square premium product photograph of a brushed titanium wristwatch standing upright on dark green marble. The watch has a cream dial, thin black hands set to 10:10, twelve distinct hour markers, a realistic crown, and a dark brown leather strap. Soft window light from the left, controlled reflections, shallow depth of field, no text, no logo, no extra objects.

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

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.
