Same prompt, both models
Unedited, at 1 megapixel, with the exact prompt each pair was given. How we ran the test.
Photorealism
What to look for: skin texture, natural light and a believable shallow depth of field.
“Close-up portrait of an elderly fisherman with a weathered face and grey stubble, wearing a yellow raincoat, soft overcast light from a window, shallow depth of field, 85mm photograph”

Text rendering
What to look for: both lines of text spelled correctly and placed on the sign, not floating beside it.
“A vintage enamel sign on a brick wall that reads "FRESH BREAD DAILY" in bold red serif letters, with "since 1962" in smaller script below, morning sunlight”

Product shot
What to look for: glass, metal and water rendered convincingly in one studio setup.
“A frosted glass perfume bottle with a brass cap on wet black slate, droplets on the glass, soft rim light, reflections on the stone, studio product photography”

Prompt adherence
What to look for: exactly three red cubes on the sphere, with the cone on the left and the cylinder on the right.
“Three red cubes stacked on top of a blue sphere, a green cone to the left and a yellow cylinder to the right, on a black and white checkerboard floor, soft studio lighting”

Illustration
What to look for: a consistent watercolor-and-ink style rather than a photo with a filter.
“Children's book illustration of a fox in a knitted scarf reading a book under a large mushroom in light rain, soft watercolor and ink, warm palette”

Complex scene
What to look for: mixed light sources, wet reflections and several subjects in one frame.
“A narrow street in Tokyo at night after rain, neon signs reflecting in puddles, a cyclist with an umbrella passing a lit ramen shop, cinematic”
