Geometric Composition
Text-to-Image“A glass cube on a wooden table. Inside the cube is a small blue sphere. On top of the cube sits a red book. A green plant is behind the cube, partially visible through the glass. Soft window light from the left.”
Nano Banana 2
OmniGen v2
AI Judge Analysis
Nano Banana 2
- + Exceptional photographic realism with natural textures on the wooden table and plant leaves.
- + Follows all spatial instructions including the sphere inside the cube and the plant behind it.
- + Includes legible, contextually relevant text on the book spine.
- − The glass cube has some impossible geometry with the back corner edges appearing slightly confused with the plant behind.
OmniGen v2
- + Clean, minimalist composition with vibrant colors.
- + Accurately places all requested elements in the correct positions.
- + Reflections on the table and sphere are well-rendered for a CGI-style look.
- − The sphere appears to be floating unnaturally rather than resting on the bottom of the cube.
- − The overall image looks significantly more like a 3D render than a real photograph compared to the other model.
Verdict: Nano Banana 2 produces a much more realistic and detailed photograph with clever touches like the thematic book title 'The Greenhouse Effect'. OmniGen v2 successfully follows all prompt instructions but lacks the textural depth and convincing lighting found in Nano Banana 2, resulting in a more plastic-like appearance.
Candid Street Photography
Text-to-Image“A candid street photo of an elderly Japanese man repairing a red bicycle in light rain, reflections on wet pavement, shallow depth of field, 50mm lens, natural skin texture, imperfect framing, motion blur from passing cars, cinematic but realistic, no stylization.”
Nano Banana 2
OmniGen v2
AI Judge Analysis
Nano Banana 2
- + Excellent adherence to the 'candid street photo' aesthetic with authentic urban Japanese signage.
- + Strong realism in the man's skin texture and clothing.
- + Effective use of reflections on the wet pavement and complex lighting.
- − Physical logic error where the wrench handle is disconnected from the hand.
- − The red bicycle's frame geometry is slightly distorted/melted near the rear wheel.
OmniGen v2
- + Clean composition with a clear subject.
- + Strong color contrast with the vibrant red bicycle.
- − Fails the 'repairing' prompt as the man is simply standing with the bike.
- − Lacks the requested 'motion blur from passing cars' and 'imperfect framing'.
- − Rain effect looks like a simple digital overlay rather than a natural environmental interaction.
Verdict: Nano Banana 2 captures the complex atmosphere of a rainy Japanese street with authentic details and a genuine 'candid' feel. OmniGen v2 fails to follow multiple prompt instructions, such as the act of repairing the bike and the motion blur of cars, resulting in a generic and less realistic image. Nano Banana 2 is the clear winner for its superior storytelling and adherence to the cinematic photographic style.
Fantasy Warrior
Text-to-Image“Close portrait of a battle-worn paladin in ornate engraved plate armor, hair braided with small beads, faint scars and dirt on the skin, warm torchlight reflecting off metal, shallow depth of field, bokeh sparks, lifelike eyes, highly detailed texture on leather straps and cloth underlayer.”
Nano Banana 2
OmniGen v2
AI Judge Analysis
Nano Banana 2
- + Excellent adherence to the 'battle-worn' descriptor with realistic dirt and facial textures.
- + Superior detail in the engraved plate armor, showing complex runes and metallic wear.
- + Very high quality texture on the leather straps and underlayer fabric.
- − The hand holding the sword has anatomical inconsistencies, particularly in the finger placement.
OmniGen v2
- + Clean composition with a very strong bokeh effect from the background fire.
- + Clearer rendering of the requested beads in the hair braids.
- − Does not look 'battle-worn'; the skin is too smooth and the dirt looks like applied makeup.
- − The armor texture is less detailed and lacks the realistic weathering seen in the other image.
- − Missed the 'faint scars' requirement in favor of a polished aesthetic.
Verdict: Nano Banana 2 is the clear winner for its superior interpretation of the 'battle-worn' paladin archetype, featuring grit and highly detailed textures that match the prompt perfectly. OmniGen v2 produced a much cleaner, airbrushed portrait that failed to capture the realistic scars and weathering requested, looking more like a cosplay than a veteran warrior.
Modern Clean Menu
Text-to-Image“Modern minimalist restaurant menu design, white background with colorful food photos in grid, sections for appetizers/pizza/mains, bold sans-serif fonts, vibrant accents, clean professional layout for casual dining.”
Nano Banana 2
OmniGen v2
AI Judge Analysis
Nano Banana 2
- + Excellent text legibility with accurate spelling throughout.
- + Clear and professional grid layout that follows all prompt requirements.
- + High-quality, realistic food photography that aligns with the specific menu items.
- − The layout is slightly crowded towards the top sections.
- − Vibrant accents are present but somewhat limited to the label bars.
OmniGen v2
- + Strong use of vibrant color accents and minimalist white space.
- + Good balance of image grid and text blocks.
- − Severe spelling errors in headers like 'PIZZZZAN' and 'RESTAURATED MENTS'.
- − The text description for menu items is unreadable gibberish.
- − Only captures two of the three requested sections (Mains are missing/mislabeled).
Verdict: Nano Banana 2 is the clear winner as it produces a fully functional and professional menu design with legible, correctly spelled text and high-quality food photography. OmniGen v2 fails significantly on the text rendering, producing nonsensical words and unreadable blocks, which makes the design unusable for a real-world application.
Magic Burger Explosion: Fiery Photorealism Challenge
Text-to-Image“Ad for 'Magic Burger'. Dynamic, exploded burger with all components (bun, patty, cheese, lettuce, tomato, sauce) suspended in mid-air. Emphasize photorealistic detail and a sense of motion. Dark, fiery background with glowing embers. Integrate text: 'MAGIC BURGER' as a prominent title, 'LIMITED TIME ONLY' as a secondary message, and '€6.99' in a starburst, all rendered with a fiery, glowing effect.”
Nano Banana 2
OmniGen v2
AI Judge Analysis
Nano Banana 2
- + Excellent adherence to the 'exploded burger' requirement with all components clearly suspended.
- + Superior photographic detail and texture in the food elements like the patty and sauce splashes.
- + Strong integration of all requested text with the correct pricing symbol and fiery effects.
- − The background is slightly busy, though it fits the 'fiery' prompt well.
OmniGen v2
- + Clean, vibrant colors that pop against the dark background.
- + Bold, legible main title text.
- − Completely failed the 'exploded burger' requirement, showing a mostly assembled burger.
- − The secondary text 'LIMITED TIME ONLY' is cut off at the edge of the frame.
- − Missing the Euro currency symbol requested in the pricing starburst.
Verdict: Nano Banana 2 is the clear winner as it followed every instruction, specifically the complex 'exploded burger' layout and the specific currency symbol. OmniGen v2 failed to explode the burger components and had technical errors with text placement, resulting in a much less dynamic advertisement.
Chalkboard Menu
Text-to-Image“Handwritten-style chalkboard menu in a cozy café, all text rendered in the exact same realistic chalk handwriting style with natural variations in letter size, slight slant, and chalk texture — no printed or digital fonts anywhere on the board. Title at the top in elegant cursive chalk handwriting: ‘TODAY’S SPECIALS – APRIL 30, 2026’. Below it, three menu items also in the same handwritten chalk style: ‘Truffle Mushroom Risotto – $24’, ‘Grilled Octopus with Lemon & Herbs – $28’, ‘Brown Butter Chocolate Chip Cookies – $9’. At the very bottom, smaller text in the identical handwritten chalk style (slightly smaller but still clearly legible with the same handwriting characteristics): ‘All items made fresh daily • Ask about our gluten-free options’. Warm ambient café lighting, visible chalk dust and smudges, realistic handwriting imperfections, no clean printed text anywhere.”
Nano Banana 2
OmniGen v2
AI Judge Analysis
Nano Banana 2
- + Excellent text rendering with perfect spelling and realistic chalk texture.
- + Deeply atmospheric background with high visual quality and depth of field.
- + Accurately follows the prompt instructions, including the specific date and menu items.
- − The title is in a clean sans-serif/script mix rather than the requested 'elegant cursive'.
OmniGen v2
- + Natural variation in the chalk texture on some letters.
- − Significant spelling errors, including 'SPECALS' and garbled menu item text.
- − Poor composition with text overlapping and messy placement of prices.
- − Lacks the atmospheric cafe background requested by the prompt.
Verdict: Nano Banana 2 is far superior, delivering near-perfect text legibility and a beautiful, coherent cafe setting. OmniGen v2 struggled significantly with the text rendering, producing several spelling errors and a disorganized layout that failed to follow the prompt's specific menu requirements.
The Reversed Rodeo
Text-to-Image“Horse riding astronaut in space — horse on top, not vice versa. Surreal, highly detailed, cinematic.”
Nano Banana 2
OmniGen v2
AI Judge Analysis
Nano Banana 2
- + Successfully followed the difficult spatial constraint of 'horse on top'.
- + High cinematic quality with impressive lighting, atmosphere, and detail.
- + Creative interpretation of 'surreal' with the upside-down riding position.
- − The astronaut's leg and hand positioning are physically confusing.
- − Some minor harness details are messy.
OmniGen v2
- + Clean, simple character and animal anatomy.
- + Clear representation of an astronaut and a horse.
- − Completely failed the negative constraint/instruction of 'horse on top'.
- − Lacks the 'cinematic' and 'highly detailed' quality of the galaxy background.
- − Composition is very basic and lacks the requested surrealism.
Verdict: Nano Banana 2 is the clear winner as it successfully interpreted the complex prompt instruction to place the horse on top, whereas OmniGen v2 defaulted to a standard horse-riding image. Nano Banana 2 also captures the atmospheric and surreal tone requested, while OmniGen v2 feels like a basic clip-art style illustration.
The Capybara Taxi Driver
Text-to-Image“Photorealistic scene inside a yellow New York taxi at night. A capybara is driving, wearing a yellow taxi driver cap and a dark jacket. It has a calm, professional expression and both front paws on the steering wheel. In the back seat sits a human businesswoman in a coat, looking at her phone with a completely normal, bored expression (as if this is just another normal ride). Through the windows you can see the streets of Manhattan at night with blurred lights. Realistic taxi interior, photorealistic, detailed fur and fabric, 35mm lens, night lighting with reflections, shallow depth of field.”
Nano Banana 2
OmniGen v2
AI Judge Analysis
Nano Banana 2
- + Excellent photorealism with an authentic New York taxi interior including meter and driver license.
- + Perfect prompt adherence with the capybara's paws on the wheel and the passenger bored in the back seat.
- + High detail in textures, from the capybara's fur to the rainy windshield and city lights.
- − The 'captain' name on the license is slightly humorous but the text on the signage has minor AI gibberish.
OmniGen v2
- + Features a bright yellow hat as requested.
- + The capybara and passenger are clearly visible in the frame.
- − Total failure in composition, showing a human hand coming out of the capybara's jacket to steer.
- − The passenger appears to be in the front seat or mid-car rather than the back seat.
- − Visual style is more digital/plastic than photorealistic.
Verdict: Nano Banana 2 is the clear winner, delivering a highly cinematic and photorealistic interpretation of the prompt with incredible attention to detail, including a 'Captain Cappy' ID. OmniGen v2 fails on basic anatomy and logic, showing human hands driving the car while the capybara's head is superimposed on a human body.
The Halloween Invitation
Text-to-Image“Vintage gothic Halloween party invitation. Dark parchment poster, spooky border with webs and thorns, central glowing jack-o-lantern, bats, twisted trees, moody night sky. Add elegant gothic title text saying "Halloween Party Invitation", a small scroll banner saying "You are invited to a night of frights", and event details at the bottom: Date: 30.10.2026 Time: 7pm Location: The Arches, NYC Spooky but polished, cinematic lighting, square format.”
Nano Banana 2
OmniGen v2
AI Judge Analysis
Nano Banana 2
- + Perfect text rendering for all requested details and the specific phrases.
- + Intricate and aesthetically pleasing gothic composition with excellent details like skulls and cobwebs.
- + Coherent parchment texture and consistent vintage lighting.
- − The text at the bottom is slightly crowded compared to the top.
OmniGen v2
- + Bold, clean colors and a clear central jack-o-lantern focal point.
- + Correctly follows the square format and dark parchment border concept.
- − Significant text errors and garbled characters in the banner and bottom details.
- − Lacks the 'vintage gothic' complexity, appearing more like a modern vector illustration.
- − Fails to render the full text strings requested, repeating '7pm' and misspelling 'The Arches'.
Verdict: Nano Banana 2 is the clear winner as it flawlessly rendered all requested text, including the specific date and address, whereas OmniGen v2 struggled with spelling and legibility. Nano Banana 2 also better captured the 'vintage gothic' and 'cinematic' aesthetic with its rich detail and illustrative style, compared to the flatter, more cartoonish look of OmniGen v2.
Isometric Miniature Diorama Scenes
Text-to-Image“Create a clear, 45° top-down isometric miniature 3D cartoon scene of Japan's signature dish: sushi, with soft refined textures, realistic PBR materials, gentle lighting, on a small raised diorama base with minimal garnish and plate. Solid light blue background. At top-center: 'JAPAN' in large bold text, 'SUSHI' below it, small flag icon. Perfectly centered, ultra-clean, high-clarity, square format.”
Nano Banana 2
OmniGen v2
AI Judge Analysis
Nano Banana 2
- + Excellent high-detail PBR materials and realistic lighting.
- + Accurate Japanese flag icon placement.
- + High visual complexity with a diverse variety of sushi types.
- − Texture style is more realistic than the requested '3D cartoon' aesthetic.
- − Text is placed side-by-side rather than stacked vertically as requested.
OmniGen v2
- + Perfect adherence to the 3D cartoon/isometric miniature style.
- + Followed typography layout perfectly with 'JAPAN' large and 'SUSHI' below.
- + Clean, solid blue background as requested.
- − Small flag icon at the top is incorrect/generic.
- − Anatomy of the sushi is nonsensical, blending nigiri toppers into maki rolls.
- − Lower overall detail compared to Model A.
Verdict: Nano Banana 2 produces a much more visually impressive and technically accurate image, although it leans more toward realism than the specific '3D cartoon' style requested. OmniGen v2 captures the requested layout and isometric cartoon styling perfectly but fails significantly on the actual content of the sushi and the accuracy of the flag icon. Nano Banana 2 is the preferred winner for its superior rendering quality and accurate cultural icons.
Adorable Baby Animals in Sunny Meadow
Text-to-Image“Hyper-photorealistic scene of fluffy baby animals—a golden retriever puppy, tabby kitten, baby bunny, and red fox kit—with big expressive eyes and ultra-detailed soft fur, playfully chasing butterflies and tumbling together in a lush wildflower meadow, warm golden sunrise light with god rays and dew sparkles, joyful wholesome vibe, 8K masterpiece.”
Nano Banana 2
OmniGen v2
AI Judge Analysis
Nano Banana 2
- + Excellent adherence to the photographic and realistic style requested.
- + Follows the prompt's count and species list perfectly, including all four animals.
- + Dynamic composition with realistic 'god rays' and dew sparkles on the grass.
- − None significant, though the fox's hind leg is slightly blurred due to depth of field.
OmniGen v2
- + Bright, cheerful colors that convey a wholesome vibe.
- + Clean rendering with no anatomical glitches across the subjects.
- − Failed to include the baby bunny as requested in the prompt.
- − The style is very plastic/3D-animated rather than 'hyper-photorealistic'.
- − Static posing neglects the 'tumbling' and 'chasing' actions requested.
Verdict: Nano Banana 2 followed every detail of the prompt, delivering a hyper-realistic, dynamic scene with all four requested animals and atmospheric lighting. OmniGen v2 failed to include the bunny and produced a cartoonish, static image that ignored the request for photorealism and action.
Studio Ghibli Anime Style
EditingEdit instruction
“Transform this photo into a Studio Ghibli–inspired illustration. Use soft pastel colors, hand-painted textures, gentle lighting, dreamy backgrounds, and a warm, nostalgic mood”
Source
Nano Banana 2
OmniGen v2
AI Judge Analysis
Nano Banana 2
- + Perfectly captures the Studio Ghibli aesthetic with watercolor textures and soft, painterly backgrounds.
- + Preserves the original source image's composition and character expressions (especially the man's longing look and the girlfriend's anger) much better.
- + Effectively uses soft pastel colors and dreamy lighting as requested in the prompt.
- − The foreground woman's face is slightly blurry, though this mimics the depth of field in the original photo.
OmniGen v2
- + Clean, vibrant anime-style lines and clear character features.
- + Preserves the basic structural layout and color scheme of the source image.
- − Completely fails to capture the emotions of the original photograph; the man and the girlfriend both appear vaguely happy rather than conflicted and angry.
- − The style is more generic modern anime than the specific hand-painted Studio Ghibli aesthetic requested.
- − Lacks the 'warm, nostalgic' texture requested, appearing very digital.
Verdict: Nano Banana 2 is the clear winner as it successfully translates both the visual style and the emotional narrative of the original photograph into a Ghibli-esque illustration. While OmniGen v2 creates a clean image, it fails to preserve the crucial expressions that make the 'Distracted Boyfriend' meme recognizable, resulting in a generic and flat output.
Golden Hour Stroll
Image EditingEdit instruction
“Add dynamic motion to this photo: make hair blow in the wind, add leaves flying, energetic and lively feel.”
Nano Banana 2
OmniGen v2
AI Judge Analysis
Nano Banana 2
- + Excellent adherence to the 'energetic and lively' instruction through an improved facial expression.
- + Successfully added wind-blown hair and flying leaves that match the scene's lighting.
- + Strong source preservation of the background details, clothing, and dog.
- − The leash handle area has some minor artifacting where it connects to the hand.
OmniGen v2
- + Successfully applied wind-blown hair effect.
- + Maintained the basic composition and identity of the subjects.
- − The flying leaves look like flat, low-quality clip-art 2D overlays.
- − The overall image quality and skin textures are significantly smoothed and less realistic compared to the original.
- − The dog's face and fur details are noticeably blurred and simplified.
Verdict: Nano Banana 2 is the clear winner as it skillfully integrates the requested movement while enhancing the subjects' expressions to match the new energy of the scene. OmniGen v2 significantly degraded the overall image quality, resulting in a plasticky look with poorly integrated graphic elements for the leaves.
Vintage Cafe Logo
Text-to-Image“Vintage minimalist restaurant logo for "Caffè Florian", retro cloche dome with steam and "Est. 1720" banner, classic typography, warm brown and cream tones, subtle texture on light background, vector emblem style.”
Nano Banana 2
OmniGen v2
AI Judge Analysis
Nano Banana 2
- + Perfect text rendering of Caffè Florian with correct accents and spelling.
- + Excellent vintage aesthetic with detailed woodcut-style shading.
- + Strong vector emblem composition with a decorative border and banner.
- − The subtle texture on the background is slightly less noticeable than requested.
OmniGen v2
- + Clean minimalist silhouette design.
- + Correct warm brown and cream color palette.
- + Accurate date rendering for Est. 1720.
- − Misspelled brand name as CAFFFLORIN rather than Caffè Florian.
- − The banner placement overlaps the cloche awkwardly.
- − Lacks the classic typography and sophisticated texture mentioned in the prompt.
Verdict: Nano Banana 2 is the clear winner as it perfectly captures the vintage emblem style and renders all requested text accurately, including the accent on 'Caffè'. OmniGen v2 failed the spelling of the core brand name and provided a much simpler, less professional layout.
Apollo 11: Journey to Tranquility
Text-to-Image“Create a clean, modern vector infographic poster about the Apollo 11 mission. NASA-inspired palette (navy, white, muted red, light gray). Flat-vector style, crisp lines, consistent iconography, subtle gradients only. Steps (stop at landing): 1. Launch (Saturn Vicon) 2. Earth Orbit (Earth + orbit ring icon) 3. Translunar (trajectory arc icon) 4. Lunar Orbit (Moon + orbit ring icon) 5. Descent (lunar module descending icon) 6. Landing (lunar module on the surface icon) Small supporting elements (minimal text): • Crew strip: three silhouette icons with only last names: Armstrong, Aldrin, Collins. • Landing site marker: Moon pin labeled "Tranquility" only. Layout constraints: generous margins, large readable labels, clean background with subtle stars. Vector-only, print-poster look, high resolution.”
Nano Banana 2
OmniGen v2
AI Judge Analysis
Nano Banana 2
- + Excellent typography with clean, readable, and mostly correctly spelled English text.
- + Strict adherence to the 6 requested infographic steps with logical, high-quality vector iconography.
- + Perfect application of the NASA-inspired color palette and flat-vector style.
- − One extra figure in the astronaut section that doesn't correspond to a specific name.
OmniGen v2
- + Follows the requested color palette reasonably well.
- + Includes some related keywords like 'Tranquility' and 'Aldin'.
- − Numerous spelling errors including 'Apolo 17' and 'NSA' instead of NASA.
- − Fails to follow the 6 specific steps requested in the prompt, resulting in a confusing layout.
- − Poor text rendering and nonsensical iconography in several sections.
Verdict: Nano Banana 2 is the clear winner as it creates a professional-grade, legible infographic that follows every instructional step from the prompt. OmniGen v2 fails significantly on prompt adherence, providing incorrect mission numbers, severe spelling errors, and a nonsensical layout that does not represent the requested chronology.
