Nano Banana 2 vs GPT Image 2
Nano Banana 2 vs GPT Image 2 on the same five prompts: portraits, packshots, exact text, a crowded scene and a flat illustration, with real costs and speed.
Updated · Tested: Nano Banana 2; GPT Image 2 (high quality)
The verdict
On quality this is close to a draw: both spelled the sign exactly and landed every detail of the crowded scene. GPT Image 2 took the portrait test with a true close-up, where Nano Banana 2 framed wider and sharpened the skin. Nano Banana 2 costs about half as much per image and finished in seconds rather than the minute and a half GPT Image 2 took, so it is the better default for iteration; GPT Image 2 is worth it for restrained, catalog-style finals.

Realistic portrait
Skin, wrinkles, beard texture and believable depth of field are where AI portraits look plastic.
Checked: Real skin texture, not waxy · Salt-and-pepper beard · Yellow oilskin hat · Overcast harbor background · Shallow depth of field
Close-up portrait of an elderly fisherman with deep wrinkles and a salt-and-pepper beard, wearing a yellow oilskin hat, overcast harbor light, 85mm lens, shallow depth of field, documentary photograph
Weathered skin, a worn yellow oilskin hat and a busy harbor are all there, but it framed a half-length shot rather than a close-up and the boats behind are only lightly blurred. Heavy HDR-style sharpening makes the skin look crunchy.
Natural skin texture and a scuffed oilskin hat and jacket, framed tight with the background melted into soft blur. The beard reads more white than salt-and-pepper, and the harbor is only hinted at by red nets and a hull.
Product packshot
Glass, metal and a clean set test material rendering and restraint.
Checked: Frosted glass reads as frosted · Gold dropper · Travertine block · Eucalyptus sprig · Soft light from the left on a beige backdrop
A frosted glass skincare serum bottle with a gold dropper standing on a travertine block, a sprig of eucalyptus beside it, soft window light from the left, plain beige backdrop, clean beauty product photography
Frosted bottle, gold collar, pitted travertine and a eucalyptus sprig, lit by a window on the left against a beige plaster wall. It added an invented "AURA" label, spelled cleanly.
A restrained, catalog-style frame: clearly frosted glass, a gold collar, travertine, eucalyptus and window shadows raking from the left across a beige wall. Its invented "LUMIÈRE" label stays legible down to the small print.
Exact text on a sign
Spelling two lines of quoted text exactly is still the clearest separator between image models.
Checked: "BLUE HOUR COFFEE" spelled exactly · "EST. 1987" spelled exactly · Cream serif letters on enamel · Red brick wall · Late afternoon sun
A vintage enamel shop sign mounted on a red brick wall that reads "BLUE HOUR COFFEE" in cream serif letters, with "EST. 1987" in smaller letters underneath, late afternoon sun, photograph
Spelled "BLUE HOUR COFFEE" and "EST. 1987" exactly in cream serif on a round blue enamel sign, adding a small flourish and dots. The street beyond glows with late sun, though the sign itself sits in softer light.
Both lines exact in cream serif on a weathered blue enamel plate with rusted edges and corner screws. A diagonal shadow across the wall sells the late-afternoon sun.
Crowded scene, many details
A long list of people, props and actions shows whether a model follows the whole brief or only the first half.
Checked: Three kids · Girl in a red raincoat painting stars · Boy with glasses taping fins · Toddler with a colander helmet · Golden retriever watching · Cardboard rocket · Toys on the grass
Three kids building a cardboard rocket in a sunny backyard: a girl in a red raincoat painting stars on it, a boy with glasses taping on the fins, a toddler wearing a colander as a helmet, a golden retriever watching, toys scattered on the grass, warm afternoon light, photograph
All seven items, down to the boy pressing tape onto a fin and a colander tied under the toddler's chin. It also put a NASA logo and a US flag on the rocket unprompted, worth noticing for commercial work.
Every item lands, including a ladybug-print red raincoat, a tape roll on the fin and a giggling toddler in a colander. Warm low sun and a seated retriever looking on finish the brief.
Flat illustration
Style control: a limited palette and flat vector look are easy to describe and easy to miss.
Checked: Flat vector look · Teal, mustard and coral only · Cat asleep on books · Rain on the window · Paper grain
Flat vector illustration of a cozy reading nook with a cat asleep on a stack of books, a window with rain outside, limited palette of teal, mustard and coral, subtle paper grain, children's book style
Flat and detailed, with the cat asleep on cleanly titled books, rain on the window and light paper grain. The palette spreads beyond teal, mustard and coral into browns, orange and mint.
A warm, well-composed nook with strong paper grain, rain and a cat asleep on four correctly spelled books. Dark browns, gray and a black-and-white cat break the three-color palette.

Which one renders text better?+
Both spelled two lines of quoted sign text exactly in our test, in the requested serif. Text accuracy did not separate them.
Why did GPT Image 2 take so long?+
We ran it at its high-quality setting, which took roughly a minute and a half per image in our runs, against seconds for Nano Banana 2. Lower quality settings are faster but were not tested here.
