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.”
AI Judge Analysis
Nano Banana Pro
- + Excellent text legibility and clean graphic design for all three required text elements.
- + Very high photorealistic detail on the burger ingredients, especially the textures of the patty and bun.
- + Well-balanced composition with a vibrant, glowing starburst that fits the prompt perfectly.
- − The burger components feel vertically stacked rather than dynamically 'exploded'.
- − Background embers are somewhat generic compared to the motion blur in the competitor.
Seedream 4.5
- + Stronger sense of motion and 'exploded' dynamics with directional light trails and tilted angles.
- + Impressive fire-textured typography that captures the requested 'fiery effect' more literally.
- + Creative interaction between the cheese and patty, enhancing the sense of movement.
- − The starburst element in the bottom right looks a bit messy with overlapping jagged edges.
- − The overall lighting is darker, making some ingredient details less clear than in Model A.
Verdict: Nano Banana Pro produces a cleaner, more professional-looking commercial advertisement with superior food photography aesthetics and legible text. However, Seedream 4.5 better captures the 'dynamic' and 'exploded' aspects of the prompt with its aggressive angles and fiery font textures. Nano Banana Pro is the likely winner for its overall visual polish and superior execution of the starburst required by the prompt.
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.”
AI Judge Analysis
Nano Banana Pro
- + Perfect text rendering for both the title and the fine details.
- + Superior composition with symmetrical thorny borders and webs that frame the image well.
- + Atmospheric lighting that creates a strong focal point on the central jack-o-lantern.
- − The parchment texture is limited to the very edges rather than the whole background.
Seedream 4.5
- + Excellent cinematic lighting and depth of field in the background.
- + Creative use of barbed wire combined with thorns and webs for the border.
- + Accurate text spelling throughout the design.
- − The arrangement of details at the bottom is slightly cluttered and less grounded than Model A.
- − The scroll banner lacks the 'aged' gothic integration found in the first image.
Verdict: Nano Banana Pro is the winner because of its superior layout and perfectly rendered text, particularly in the event details section. While Seedream 4.5 offers beautiful cinematic lighting and a great moonlit atmosphere, Nano Banana Pro feels more like a finished invitation with its balanced composition and elegant typography.
Outfit Transfer Challenge
Editing“Use Image 1 as the base person. Dress them in the exact elaborate outfit from Image 2 (including all layers, accessories, jewelry, and shoes). Carefully adapt the clothing to the body shape and pose in Image 1 while maintaining realistic fabric behavior, correct proportions, and perfect lighting/shadow matching. Keep the person’s exact face, hair, and background completely unchanged.”
AI Judge Analysis
Nano Banana Pro
- + Retains the original person's face, features, and expression perfectly.
- + Successfully transfers all requested elements including the coat, scarf, sunglasses, watch, and ring.
- + Correctly handles the vitiligo pattern on the hand and neck while wearing the new outfit.
- − The placement of the person relative to the wooden post shifted slightly, causing some background misalignment.
- − The hand on the right (with the watch) has a slight anatomical distortion compared to the source.
Seedream 4.5
- + Excellent fabric rendering and integration of the outfit into the beach scene.
- + Accurately reproduces the specific accessories like the watch and ring.
- − Failed to keep the person's face and hair unchanged, merging the two subjects together.
- − Changed the person's head position and gaze, which was not requested.
- − Lost the skin texture of the original subject on many parts of the face.
Verdict: Nano Banana Pro followed the complex editing instructions much better by preserving the original subject's identity, face, and hair while accurately overlaying the complex outfit from the second image. Seedream 4.5 failed the primary instruction of keeping the person's face and hair unchanged, instead creating a hybrid of the two men and changing the head pose entirely.
Man and Car in California
Editing“Make a photo of the man driving the car down the California coastline”
AI Judge Analysis
Nano Banana Pro
- + Excellent integration of the man and the car into a scenic environment.
- + Maintains the specific lighting and warmth associated with the California coast.
- + Good dynamic composition with a sense of motion.
- − The man's hair is slightly simplified compared to the source image.
- − The car's interior details have some minor artifacts where they meet the shoreline.
Seedream 4.5
- + Near-perfect preservation of the man's outfit, hair, and footwear from the source image.
- + High degree of source preservation for the car's interior and door mechanics.
- + Realistic perspective of the man sitting inside the vehicle.
- − The car door is wide open while driving, which is safety-illogical and visually distracting.
- − The background is slightly more muted in color compared to the more 'Californian' feel of Model A.
- − The car lacks a driver-side mirror.
Verdict: Both models successfully combined the subjects from the two source images. Seedream 4.5 did a superior job of preserving the exact details of the man's clothing and the car's interior, but failed a logic test by leaving the car door wide open during the drive. Gemini 3 Pro Image Preview created a more cohesive and visually appealing scene that feels more like a professional photograph, despite some minor loss of detail in the man's hair.
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.”
AI Judge Analysis
Nano Banana Pro
- + Perfect adherence to all spatial instructions, including the plant behind the cube.
- + Highly realistic photographic quality with natural lighting and textures.
- + Excellent refraction and reflection properties on the glass surfaces.
- − Small smudge-like artifacts on the front glass pane.
Seedream 4.5
- + Clean, vibrant colors and sharp focus on the object.
- + Strong adherence to the book and sphere color requirements.
- − The plant is barely visible and extremely blurred, losing its identity as a green plant.
- − The blue sphere is clipping through the glass wall of the cube.
- − The geometry of the cube's base is physically impossible and distorted.
Verdict: Gemini 3 Pro Image Preview is the clear winner as it successfully follows all spatial prompts, particularly the placement of the plant behind the glass. While Seedream 4.5 captures the basic elements, it suffers from significant geometric distortions and a blue sphere that appears to be merging with the glass wall rather than inside it.
Pose & Character Mashup
Editing“Use Image 1 as the exact pose reference and Image 2 as the character reference. Recreate the person/character from Image 2 in the exact dynamic pose and body position from Image 1. Keep the exact face, hair, clothing style/details, and expression from Image 2. Match the lighting and environment of Image 1. The final image must show the character from Image 2 performing the precise action/pose from Image 1 with perfect anatomy and natural integration.”
AI Judge Analysis
Nano Banana Pro
- + Excellent character preservation including sunglasses, scarf details, and facial features.
- + Captures the lighting and yellow background of the source image perfectly.
- + Maintains the exact scarf pattern and texture from the character reference.
- − The pose is significantly altered from the reference, losing the crossed-leg balancing act.
- − The anatomy of the raised arm and hand is distorted and lacks clear definition.
Seedream 4.5
- + Captures the character's facial likeness and clothing style accurately.
- + Matches the environment and lighting of the pose reference successfully.
- + Stronger overall image clarity and resolution compared to the competitor.
- − The pose is completely changed to a simple crouch instead of the dynamic balancing pose requested.
- − The text on the shirt is garbled and does not match the reference image.
Verdict: Both models failed to replicate the complex 'crossed-leg' balancing pose from Image 1 accurately, with Nano Banana Pro attempting a stretch and Seedream 4.5 opting for a simple squat. Nano Banana Pro is slightly better for this specific request as it preserved the details of the character's scarf and accessories with much higher fidelity than Seedream 4.5.
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
- + Excellent photographic realism with a true film-like aesthetic.
- + Convincing rainy atmosphere with ripples in puddles and wet textures on clothing.
- + Perfectly captures the 'imperfect framing' requested with a slightly off-center, candid composition.
- − The passing car is sharp rather than having light trails or motion blur.
- − The man's right hand is somewhat muddled in detail against the bike frame.
Seedream 4.5
- + Captures the 'motion blur from passing cars' perfectly with long-exposure style light trails.
- + Stronger 'candid' eye contact with the subject.
- + Clearer action of 'repairing' with a visible wrench tool.
- − The bicycle mechanics are nonsensical, with a chain floating in mid-air and attached to the outside of the frame.
- − The man is kneeling directly in a deep puddle, which feels less realistic for a candid street shot.
- − Overall image has a slightly 'AI-smooth' texture compared to the grit of Model A.
Verdict: Gemini 3 Pro Image Preview produces a significantly more believable and high-quality photograph that looks like genuine 35mm street photography, despite missing the motion blur on the cars. Seedream 4.5 captures the motion blur and the repair tool well, but fails significantly on the structural integrity of the bicycle and has a more synthetic visual quality.
The Reversed Rodeo
Text-to-Image“Horse riding astronaut in space — horse on top, not vice versa. Surreal, highly detailed, cinematic.”
AI Judge Analysis
Nano Banana Pro
- + Perfectly follows the specific instruction of the horse being on top of the astronaut
- + Rich background detail with galaxies, planets, and a satellite
- + High quality rendering of the space suit and horse fur
- − The transition where the horse's hooves meet the astronaut's shoulders is a bit awkward visually
Seedream 4.5
- + Dynamic and cinematic posing of the horse
- + Vibrant and aesthetic color palette in the nebula background
- − Completely fails the primary instruction to have the horse on top of the astronaut
- − Anatomical issues with the astronaut's legs and the way they are 'riding' the horse's chest
Verdict: Nano Banana Pro successfully interpreted the challenging and surreal prompt instruction to place the horse on top of the astronaut, creating a unique and literal interpretation. Seedream 4.5 ignored the specific positioning requirement, defaulting to a standard (and anatomically messy) image of an astronaut riding a horse.
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.”
AI Judge Analysis
Nano Banana Pro
- + Excellent photorealism with realistic lighting and reflections on the taxi interior.
- + The capybara's texture and facial expression are highly convincing.
- + Detailed background city bokeh and taxi-specific elements like the fare meter.
- − The capybara's paws are rendered a bit awkwardly around the steering wheel.
Seedream 4.5
- + Includes a 'TAXI' label on the hat which reinforces the theme.
- + The businesswoman follows the boredom/phone prompt perfectly.
- + The capybara's jacket and seatbelt placement are logical.
- − The lighting feels flatter and more synthetic compared to Model A.
- − The steering wheel has a warped, digital appearance near the capybara's right paw.
Verdict: Nano Banana Pro is the winner due to its superior lighting and texture, creating a truly cinematic and photorealistic atmosphere. While Seedream 4.5 followed the prompt well, it lacked the depth of detail and realistic reflections found in Nano Banana Pro's depiction of a New York night.
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.”
AI Judge Analysis
Nano Banana Pro
- + Excellent text rendering with perfect spelling and no repetition.
- + Natural-looking chalk texture on both the board and the lettering.
- + Strong environmental depth and realistic café atmosphere.
- − The 'cursive' request for the title was interpreted more as a slanted print/script than elegant calligraphy.
- − Layout is a bit tight on the left side of the board.
Seedream 4.5
- + Text has a very authentic, slightly varying handwritten feel.
- + Good use of chalk dust and smudges to enhance the realism of the medium.
- + Center-aligned composition feels organized and legible.
- − Logically redundant text, repeating 'Risotto - $24' twice on separate lines.
- − The title font is all-caps rather than the requested 'elegant cursive'.
Verdict: Nano Banana Pro followed the text instructions perfectly, delivering clean and accurate spelling of all requested menu items with a very realistic chalk look. While Seedream 4.5 captures the 'handwritten' vibe slightly better with varied letter shapes, it fails on logic by repeating the price and item name for the first entry.
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.”
AI Judge Analysis
Nano Banana Pro
- + Excellent adherence to the grid layout request.
- + Professional typesetting with distinct sections for Appetizers, Pizza, and Mains.
- + Higher quality and more varied food photography.
- − Text contains a high amount of gibberish and repeating names.
- − The geometric accents feel slightly dated compared to modern minimalism.
Seedream 4.5
- + Clean, modern minimalist aesthetic with a very clear white background.
- + Bold, legible sans-serif fonts for section headers.
- + The colorful borders around photos provide effective 'vibrant accents'.
- − Failed the request for a 'grid' of food photos, opting for a vertical list.
- − Prices are unrealistically high (e.g., $79 for appetizers), which affects the professional look.
Verdict: Gemini 3 Pro Image Preview followed the structural instructions much better by providing a true grid layout and distinct sections as requested. Seedream 4.5 has cleaner typography and a more modern minimalist feel, but it failed the grid requirement and struggled with realistic pricing in the text.
Bald man challenge
Image Editing“Give the person a full, thick head of natural hair with realistic texture, density, and a natural hairline. Preserve facial features and lighting.”
AI Judge Analysis
Nano Banana Pro
- + The hair texture is highly realistic with varied strand directions and natural waves.
- + The hairline is very convincing, showing a soft transition into the skin.
- + Excellent preservation of the facial features, glasses, and background.
- − The added hair volume is significantly wider than the original head shape.
Seedream 4.5
- + Follows the forehead shape of the original image well.
- + Good alignment of the sideburns with the existing beard.
- − The hair texture is blurry and lacks the fine detail seen in the facial hair.
- − The hairline is quite harsh and lacks realistic 'baby hairs' or transition density.
- − Slightly altered the person's brow shape and facial expression.
Verdict: Gemini 3 Pro Image Preview provides a much more convincing and high-quality edit, featuring realistic hair texture, lighting, and a natural-looking hairline that matches the quality of the original photo. Seedream 4.5 produces a more matted, blurry hair texture that feels superimposed and doesn't blend as naturally with the existing beard hair.
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 with clean alignment and correct font weights
- + High variety of detailed sushi types and realistic food textures
- + Sophisticated diorama base with moss and cherry blossom details
- − The flag icon is slightly merged with the text layout compared to a standalone icon
Seedream 4.5
- + Accurate isometric 45-degree angle
- + Clean, minimalist composition
- + Good 3D lighting and shadow depth
- − Text is somewhat cramped and heavy
- − The texture of the diorama base looks like gritty concrete/sand rather than a refined diorama
- − Very limited variety of sushi compared to the other image
Verdict: Gemini 3 Pro Image Preview is the clear winner as it provides a much more professional and detailed illustration. It features a wide variety of sushi, superior text rendering, and a more aesthetically pleasing diorama base that fits the 'refined textures' prompt better than the gritty base in Seedream 4.5.
Over-the-top cartoon caricature
Editing“Create a caricature of me and my job. Make it exaggerated and humorous, incorporating my profession as a tv show anchor and my love for dogs and hockey.”
AI Judge Analysis
Nano Banana Pro
- + Successfully captures the 'humorous and exaggerated' tone of a traditional caricature.
- + Integrated all requested elements (anchoring, dogs, hockey) into a cohesive and busy scene.
- + The character design retains the recognizable features of the source person despite the shift in art style.
- − Compels a total change in art style toward a cartoon/illustration rather than a photo manipulation.
- − Some anatomical issues with the hands resting on the desk.
Seedream 4.5
- + Maintains a high degree of facial resemblance and realistic texture from the original photo.
- + Correctly interprets the 'bobblehead' style of caricature while keeping a photographic look.
- + Preserves the original background (living room/couch) while adding the desk and props.
- − The composition feels a bit less 'humorous' and more static compared to the chaotic energy of Model A.
- − The hockey stick and gloves look slightly pasted into the foreground with scale issues.
Verdict: Gemini 3 Pro Image Preview opted for a fully illustrated cartoon caricature style which allowed for a more creative and humorous interpretation of the prompt, including dogs playing hockey in the background and a custom news ticker. Seedream 4.5 maintained the photographic style and the source image's background, creating a high-quality 'big-head' caricature that is more grounded in the original photo's reality. Seedream 4.5 is the winner for better preserving the source person's likeness and background while still executing the requested additions and caricature effect.
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.”

Studio Ghibli Anime Style
Editing“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”
AI judge analysis unavailable for this challenge.
Golden Hour Stroll
Image Editing“Add dynamic motion to this photo: make hair blow in the wind, add leaves flying, energetic and lively feel.”
AI Judge Analysis
Nano Banana Pro
- + Excellent preservation of the original image's character, lighting, and background details.
- + The hair edit looks very natural and follows the requested motion.
- + Added leaves are colorful and well-integrated into the scene without obscuring the main subjects.
- − The leaves appear a bit sharp and lack motion blur compared to the dynamic intent of the prompt.
Seedream 4.5
- + Successfully added hair motion and flying leaves as requested.
- + Integrated motion blur on the leaves to enhance the feeling of speed and energy.
- − Failed to preserve the original image accurately, noticeably changing the woman's facial features and the dog's appearance.
- − The composition was altered, zooming out slightly and changing the path's perspective.
- − The lighting is significantly harsher and more 'blown out' compared to the source image.
Verdict: Gemini 3 Pro Image Preview is the clear winner as it perfectly preserves the identity of the woman and the dog from the source image while adding the requested motion effects. Seedream 4.5 recreates the scene rather than editing it, resulting in a different face and lighting that loses the original's charm.
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
- + Excellent hand-drawn etch style that feels authentic to the 'vintage' prompt.
- + Perfectly accurate text rendering including the grave accent on 'Caffè'.
- + Sophisticated use of negative space and line work for the steam.
- − The 'Est. 1720' text is slightly thinner than the main brand name, though still legible.
Seedream 4.5
- + Strong 'vector emblem' aesthetic that looks more like a modern-vintage badge logo.
- + Good use of warm brown and cream tones with subtle grain texture.
- + Clean, bold layout that would work well for physical signage.
- − The 'Est. 1720' banner feels a bit flat and disconnected from the circular badge.
- − The steam element is very small and lacks the 'vintage minimalist' elegance of the other model.
Verdict: Gemini 3 Pro Image Preview perfectly captures the requested vintage aesthetic with high-quality illustrations and impeccable typography. While Seedream 4.5 produces a solid vector-style badge, it lacks the artistic nuance and sophisticated line work found in Gemini 3 Pro's interpretation.
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
- + Excellent typographic layout with clear, legible headers and numbered steps.
- + The icons accurately match the requested hardware, particularly the descent and landing modules.
- + Engaging composition that makes good use of the full poster space.
- − The 'Descent' icon shows the lunar module upside down, which is technically inaccurate.
- − The trajectory line for Translunar is a bit busy with many redundant spacecraft icons.
Seedream 4.5
- + Cleanest execution of the requested flat-vector style with crisp, professional lines.
- + Highly accurate icons for the Saturn V and Lunar Module according to the prompt.
- + Logical linear timeline layout that is very typical of educational infographics.
- − The 'Descent' icon (step 5) is represented by a satellite with solar panels rather than a lunar module.
- − The composition has a large amount of empty white space at the bottom.
Verdict: Gemini 3 Pro Image Preview provides a more dynamic and visually interesting poster that feels like a complete product, though it has minor orientation issues with icon placement. Seedream 4.5 offers a cleaner, more professional flat-vector aesthetic that perfectly matches the 'modern infographic' request, but it fails to provide the correct icon for the descent stage, instead showing a generic satellite. Gemini 3 Pro is preferred for its better integration of text and illustrative flow.
