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 Pro
Stable Diffusion 3.5 Large

AI Judge Analysis

Nano Banana Pro

  • + Perfect adherence to the spatial arrangement requested.
  • + Highly realistic textures, especially the wood grain and glass reflections.
  • + Excellent lighting that feels natural and follows the prompt's direction.
  • The plant is slightly more to the side than directly behind, though it is visible through the glass.

Stable Diffusion 3.5 Large

  • + Clean, modern aesthetic.
  • + Clear visibility of the sphere and glass cube.
  • Failed the spatial instruction by placing the book inside the cube instead of on top.
  • The blue sphere appears to be floating unnaturally.
  • The plant is positioned above the cube rather than behind it.

Verdict: Gemini 3 Pro Image Preview followed the prompt's spatial instructions perfectly, placing the red book on top of the cube and the sphere inside. Stable Diffusion 3.5 Large failed the core composition by placing the cube over the book and floating the sphere, resulting in a less realistic and less accurate image.

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.”

AI Judge Analysis

Nano Banana Pro

  • + Exceptional photographic realism with natural skin textures and authentic clothing details.
  • + Perfectly captures the 'imperfect framing' and 'candid' street photography aesthetic.
  • + Highly realistic environment with legible Japanese signage and accurate wet pavement reflections.
  • The motion blur on the passing taxi is subtle rather than pronounced.

Stable Diffusion 3.5 Large

  • + Good use of shallow depth of field to isolate the subject.
  • + Strong rain effects with visible droplets on the man and bicycle.
  • + Includes more noticeable motion blur on the background bus.
  • The anatomy of the man's hands is mangled and physically impossible.
  • The bicycle frame is structurally incoherent where it meets the handlebars and pedals.
  • The image has a visible 'AI sheen' or smooth texture that contradicts the 'no stylization' request.

Verdict: Gemini 3 Pro Image Preview captures the requested 'candid street photo' look with remarkable authenticity, featuring realistic skin textures and a perfectly composed (yet intentionally imperfect) urban scene. In contrast, Stable Diffusion 3.5 Large suffers from significant anatomical errors in the hands and structural issues with the bicycle, looking much more like a digital painting than a real photograph.

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.”

100% wins 0% ties 0% wins

AI Judge Analysis

Nano Banana Pro

  • + Excellent adherence to all prompt details including beads in hair and leather straps.
  • + Superior lighting with realistic torchlight reflections and orange bokeh sparks.
  • + High-quality skin texture with convincing dirt and subtle scarring.
  • The torch in the foreground is a bit blurry and takes up significant space.

Stable Diffusion 3.5 Large

  • + Intricate engraving patterns on the armor plates.
  • + Good character expression and lifelike eyes.
  • + Detailed chainmail and cloth underlayer.
  • Missed the request for beads in the hair braids.
  • The lighting feels more like daylight than flickering torchlight.
  • Less bokeh effect and fewer sparks than requested.

Verdict: Gemini 3 Pro yielded a more atmospheric and accurate result, successfully incorporating every detail including the hair beads and the specific warm torchlight lighting. Stable Diffusion 3.5 Large produced high-quality armor engravings but failed on several prompt specificities such as the beads and the intended lighting mood.

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.”

100% wins 0% ties 0% wins

AI Judge Analysis

Nano Banana Pro

  • + Excellent layout that perfectly mimics a real restaurant menu.
  • + High-quality, appetizing food photography that is logically arranged.
  • + Text is highly legible with a clear hierarchy and relatively fewer spelling errors.
  • Repeated item names (Bruschetta and Margherita Pizza used for every line).
  • Some minor gibberish in the smaller description text.

Stable Diffusion 3.5 Large

  • + Creative use of a wide grid of food photos.
  • + Strong, bold typography for the main header.
  • The layout is less practical for a real menu with poor text legibility.
  • The text contains significant 'AI gibberish' and spelling errors (e.g., 'MAIMAES', 'APPETIZRS').
  • Does not follow the request for specific sections as effectively as the other model.

Verdict: Gemini 3 Pro Image Preview is the clear winner as it produces a professional, functional menu layout that closely follows all prompt instructions, including specific sections and a clean white background. Stable Diffusion 3.5 Large creates a more abstract design with significant text corruption and a cluttered grid that is less suitable for a casual dining menu.

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 Pro
Stable Diffusion 3.5 Large

AI Judge Analysis

Nano Banana Pro

  • + Excellent typography rendering with perfect spelling of all three requested fields.
  • + Dynamic 'exploded' composition with clear separation of ingredients.
  • + The starburst element is correctly included as requested.
  • The 'fiery' effect on the text is a bit flat compared to the burger lighting.

Stable Diffusion 3.5 Large

  • + High level of photorealistic detail on the patties and melting cheese.
  • + Strong atmospheric lighting and cinematic fire effects.
  • Completely failed to include any text or the starburst element.
  • Failed the 'exploded' requirement; the burger is assembled and floating rather than having separated components.

Verdict: Nano Banana Pro followed the prompt instructions near perfectly, including all requested text, the starburst price tag, and the specific 'exploded' layout. Stable Diffusion 3.5 Large produced a visually stunning and realistic image, but it failed almost every specific instruction regarding text and composition.

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 Pro
Stable Diffusion 3.5 Large

AI Judge Analysis

Nano Banana Pro

  • + Excellent text accuracy with no spelling errors.
  • + Perfectly follows the request for specific pricing and item names.
  • + Realistic chalk texture and board smudging effects.
  • The text looks more like a digital handwriting font than natural, variable human writing.
  • Missed the request for 'elegant cursive' for the title.

Stable Diffusion 3.5 Large

  • + Features more organic variation in letter shapes and layout.
  • + Includes the requested 'Brown But...' completion in a creative way.
  • Significant spelling errors throughout the text (e.g., 'TODAAY', 'Ottpups', 'Mughrrom').
  • Incorrect year (2024 instead of 2026).
  • The composition is far away, making the text hard to read.

Verdict: Nano Banana Pro is the clear winner for its perfect adherence to the text prompt and legible, accurate spelling of all items. While Stable Diffusion 3.5 Large attempted a more complex layout, it suffered from severe hallucinations in the spelling and failed to follow the specific date and pricing instructions.

The Reversed Rodeo

Text-to-Image

“Horse riding astronaut in space — horse on top, not vice versa. Surreal, highly detailed, cinematic.”

Nano Banana Pro
Stable Diffusion 3.5 Large

AI Judge Analysis

Nano Banana Pro

  • + Excellent adherence to the specific 'horse on top' spatial instruction
  • + Surreal and humorous composition featuring a horse wearing a cosmic cape
  • + High clarity and clean rendering of both the astronaut suit and the horse
  • The astronaut holding the horse is more of a 'carrying' pose than a 'riding' pose
  • Some anatomical awkwardness where the horse's hoof meets the astronaut's hand

Stable Diffusion 3.5 Large

  • + Atmospheric and cinematic lighting with great particle effects
  • + Strong sense of motion and scale in the background planet
  • + Intricate detail on the astronaut's life support systems
  • Failed the negative constraint; the astronaut is riding the horse instead of the inverse
  • Anatomy issues with the horse's front legs merging into the light trails

Verdict: Nano Banana Pro successfully interpreted the challenging 'horse on top' spatial prompt, creating a surreal image where the astronaut serves as the mount. While Stable Diffusion 3.5 Large produced a more visually cinematic and epic environment, it completely ignored the specific instruction to reverse the traditional riding roles.

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 Pro
Stable Diffusion 3.5 Large

AI Judge Analysis

Nano Banana Pro

  • + Excellent adherence to the full prompt, including the specific passenger and her expression.
  • + Highly photorealistic lighting and textures for both the animal and the taxi interior.
  • + Superior composition that captures the scene's requested scale and narrative context.
  • The capybara's paws on the steering wheel are slightly small and less defined.
  • A bit of lens distortion near the edges of the frame.

Stable Diffusion 3.5 Large

  • + Bright, vibrant colors and sharp details on the capybara's fur.
  • + Strong rendering of the leather jacket and modern baseball cap.
  • Completely failed to include the human businesswoman in the back seat.
  • The capybara's paws are not on the steering wheel as requested, with one floating in the air.
  • The perspective and character anatomy (legs) feel slightly inconsistent with a seated driver.

Verdict: Nano Banana Pro followed every aspect of the prompt, including the specific demand for a bored businesswoman in the back seat, creating a cohesive and humorous narrative. In contrast, Stable Diffusion 3.5 Large ignored the passenger entirely and failed to place the driver's paws on the steering wheel, resulting in a much less accurate output despite its vibrant colors.

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 Pro
Stable Diffusion 3.5 Large

AI Judge Analysis

Nano Banana Pro

  • + Perfect text rendering for all requested details including date, time, and location.
  • + Excellent composition with a focused central jack-o-lantern and symmetrical gothic borders.
  • + Follows the 'Vintage gothic' aesthetic perfectly with atmospheric lighting and aged parchment textures.
  • The glowing effect on the text makes the smaller details slightly thicker, though still very readable.

Stable Diffusion 3.5 Large

  • + Good use of negative space and a large, impressive moon in the background.
  • + Detailed scroll illustration at the bottom.
  • Failed to include the specific event details (Date, Time, Location) requested in the prompt.
  • Text rendering is inconsistent with some gibberish characters below the main banner.
  • Poor adherence to the 'square format' request as it produced a vertical composition.

Verdict: Nano Banana Pro is the clear winner as it fulfilled every aspect of the prompt, including the complex requirement of rendering specific event details accurately. Stable Diffusion 3.5 Large failed to include the event information and ignored the square format instruction, resulting in a less functional invitation design.

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.”

AI Judge Analysis

Nano Banana Pro

  • + Excellent text rendering and layout following the spatial instructions.
  • + Superior material realism with believable textures for the fish and rice.
  • + Clean, minimalist composition that perfectly matches the 'diorama' and 'isometric' request.
  • The lighting is a bit flat compared to the PBR request, though it remains professional.

Stable Diffusion 3.5 Large

  • + Captures the '3D cartoon' style effectively with vibrant colors.
  • + Good use of 3D modeling aesthetics for the base and background elements.
  • Failed to place the text at the top-center as requested, putting it on a small flag instead.
  • The sushi models look more like plastic toys than the requested refined PBR materials.
  • The composition feels more cluttered and less 'ultra-clean' than the prompt specified.

Verdict: Gemini 3 Pro Image Preview followed the prompt with much higher precision, correctly placing the text at the top-center and utilizing a cleaner isometric layout. While Stable Diffusion 3.5 Large interpreted the 'cartoon' aspect well, it ignored the specific text placement instructions and the textures look significantly more artificial.

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.”

AI Judge Analysis

Nano Banana Pro

  • + Excellent clarity and sharpness across all four animals
  • + Vibrant colors and highly detailed fur textures
  • + Perfect adherence to the list of animals, correctly identifying all four types
  • Has a slightly more 'digital' or CGI-rendered look rather than true photorealism

Stable Diffusion 3.5 Large

  • + Beautiful soft lighting and bokeh effect that feels more like a professional photograph
  • + Great sense of motion and dynamic energy in the composition
  • The cat and fox look very similar, lacking distinct features for the kitten
  • A butterfly is awkwardly merged with the rabbit's ear
  • Slight lack of fine detail in the background and foreground elements

Verdict: Gemini 3 Pro Image Preview provides a much clearer and more accurate representation of the four distinct animals requested, with sharp details and vibrant colors. Stable Diffusion 3.5 Large offers more atmospheric lighting and a photographic feel, but suffers from anatomical errors, such as a butterfly growing out of a rabbit's ear, and less distinction between the kitten and the fox kit.

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.”

AI Judge Analysis

Nano Banana Pro

  • + Perfect text rendering for 'Caffè Florian' including the grave accent.
  • + Excellent hand-drawn etch style that fits the vintage aesthetic.
  • + Clean, professional composition with a balanced banner.

Stable Diffusion 3.5 Large

  • + Follows the color palette and minimalist prompt well.
  • + Includes decorative corner accents that enhance the vintage feel.
  • Spelling error in the main title ('Cafféé' instead of 'Caffè').
  • The cloche graphic is poorly constructed, appearing to float disjointedly above a strange flame/steam element.
  • The layout is vertically stretched and less cohesive as a logo.

Verdict: Gemini 3 Pro Image Preview is much more successful, delivering a high-quality vector-style emblem with perfect typography and a charming hand-etched illustration style. Stable Diffusion 3.5 Large fails on text accuracy and creates a confusing, disjointed cloche graphic that lacks the professional finish of a real logo.

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.”

AI Judge Analysis

Nano Banana Pro

  • + Perfectly follows the requested 6-step structure and narrative flow.
  • + Excellent text rendering for headers, labels, and names.
  • + Consistent flat-vector style with professional iconography.
  • The 'Descent' icon is slightly cluttered compared to the other clean vectors.
  • Missing the NASA red in the text, though present in the rocket illustration.

Stable Diffusion 3.5 Large

  • + Captures the NASA-inspired color palette effectively.
  • + Includes complex textured elements for the lunar surface.
  • Failed to follow the requested 6-step infographic structure.
  • Text is mostly illegible gibberish and 'Lannch' is misspelled.
  • Inaccurate imagery including a Space Shuttle-style orbiter instead of Saturn V.

Verdict: Gemini 3 Pro Image Preview is the clear winner as it perfectly adheres to the complex infographic structure requested in the prompt, rendering all six steps with legible text and appropriate icons. Stable Diffusion 3.5 Large failed to follow the logical sequence, produced illegible text, and incorrectly used a Space Shuttle wing design for an Apollo 11 mission prompt.
