Nano Banana 2.1vs.FLUX.1 Kontext [max]

Which one is better?

In our own test, Nano Banana 2.1 leads. Neither is in the arena. Neither has an API price.

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

Nano Banana 2.1: Product photography, first image from the fixed test run — Nano Banana 2.180 out of 100

FLUX.1 Kontext [max]: Product photography, first image from the fixed test run — FLUX.1 Kontext [max]9 out of 100

Result for “Product photography”:Nano Banana 2.1 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

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.
