We ran Nano Banana 2 and its two closest rivals through six fixed prompts inside Krater on 27 Sep 2026. 1:1, 1024 px, one image per prompt, default settings, no prompt tuning, first output kept. Every output below is the first result, unedited.
Tests: photorealism, materials, lighting
Studio product photograph of a matte black ceramic coffee mug with a walnut wood lid, on a light grey concrete surface, soft window light from the left, shallow depth of field, a few coffee beans scattered in the foreground, no text, no logo.
Tests: skin, hands, eyes, natural light
Candid photograph of a woman in her sixties with short grey hair laughing while holding a yellow bicycle helmet in both hands, standing on a cobblestone street in Copenhagen at golden hour, 85mm lens, natural skin texture, both hands fully visible.
Tests: exact text rendering, layout
Minimalist concert poster. Large headline text reading "NORTH SEA JAZZ" at the top, smaller text "Rotterdam 10 to 12 July" at the bottom, a single saxophone silhouette in the middle, mustard yellow background, navy blue ink, risograph print style.
Tests: style control, charm, composition
Children's book illustration of a small red fox reading a map under an oversized green umbrella in the rain, forest in the background, watercolor and ink, warm palette, whimsical, storybook style.
Tests: counting, spatial layout, colours
Flat lay photograph on a white table: exactly three green apples in a row on the left, one blue ceramic bowl on the right containing exactly two lemons, a folded red napkin above the bowl, shot from directly above, even lighting.
Tests: labels, structure, legibility
Clean infographic showing a simple three-step process, horizontal, with three numbered circles connected by arrows. Labels under the circles read "Plan", "Build" and "Launch". Flat vector style, white background, teal and charcoal colours, sans-serif text.
Pass, partial and fail are about following the prompt (text, counts, layout, constraints), not about taste. Same prompt, same settings, no model-specific tuning. Read the full 10-model test
