Pro and 2.1 on the same 8 prompts
We ran the same eight prompts through both on October 7, 2026, one try each at 1K, nothing retouched. Short version: 2.1 matched Pro on text, the infographic, the product shot and all three photo edits, and got the counting test right. Pro made the most detailed portrait. Full write-up: Nano Banana 2.1 vs Pro.
1. Words on a chalkboard
Prompt: "A bakery chalkboard menu, hand-lettered in white chalk, that reads exactly: TODAY — Cinnamon Roll $4 — Sourdough Loaf $7 — Oat Latte $5. Warm cafe light, a few croissants on the counter in front." · 4:3, 1K
Every line came out spelled right in both, prices included. Pro's lettering looks a bit more like real chalk; 2.1 kept the dashes we asked for.
2. An infographic with four steps
Prompt: "A clean flat infographic titled 'How Coffee Gets to Your Cup' with four numbered steps in a vertical column: 1 Harvest, 2 Dry, 3 Roast, 4 Brew. Each step has a simple icon and a one-line caption. Cream background, brown and green accents." · 3:4, 1K
Both got the title, all four steps and readable captions. Pro's layout is tidier, 2.1's has more character. Call it a draw.
3. A realistic portrait
Prompt: "Candid 35mm film photo of an elderly fisherman mending a net on a wooden dock at dawn, weathered hands, soft natural light, shallow depth of field." · 4:5, 1K
Pro wins this one. The face, the knit sweater and the hands are closer and sharper. 2.1's is a good photo, just wider and softer.
4. Counting objects
Prompt: "Exactly five red apples and three green pears in one straight row on a wooden table, studio lighting, white background." · 16:9, 1K
The clearest difference in our runs. We asked for exactly five apples and three pears. 2.1 got it right; Pro made four apples and alternated them with the pears.
5. A product ad
Prompt: "Commercial ad photo: a pair of white running shoes floating above a puddle on a city street at night, pink and blue neon reflections in the water." · 1:1, 1K
Both look like real ads. Pro invented neon signs with a made-up brand ('NEO-STRIDE'), which you'd have to clean up before using it. 2.1's has no stray text.
6. Restoring an old photo
Edit prompt: "Restore this old photo: remove the scratches, creases, dust and the torn corner, sharpen the faces and colorize it naturally. Keep the people, their poses and the composition exactly the same." · 4:3, 1K
Both removed the damage, kept both faces and colorized naturally. They picked different colors for the clothes, which is a guess either way.
7. A phone snapshot into a product photo
Edit prompt: "Turn this into a professional product photo: the same candle on a travertine stone pedestal, soft warm light from the side, a gentle shadow, a clean beige background and a few dried flowers. Keep the jar and its label exactly the same." · 4:5, 1K
Both kept the FIG & CEDAR label letter for letter. Pro's pedestal is a smooth cylinder; 2.1's looks more like real travertine. Either works for a shop listing.
8. A pet photo into a collectible figure
Edit prompt: "Create a 1/7 scale commercialized figurine of the cat in the picture, in a realistic style, in a real environment. The figurine stands on a round transparent acrylic base with no text, on a computer desk. The computer screen shows the 3D modeling of this figurine. Next to the screen is a premium collectible toy box printed with artwork of the same cat." · 1:1, 1K
Both kept the cat's sitting pose and its markings. 2.1's toy box is busier and more fun; Pro's is calmer.
