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
- + Excellent photographic realism with film-like texture.
- + Accurately represents the spatial arrangement and lighting direction.
- + Natural-looking green fern with realistic lighting interaction.
- − The glass cube has some perspective issues on the left edge.
- − The blue sphere is slightly small relative to the prompt 'small blue sphere' and looks more like a marble.
Seedream 4.0
- + Clean, vibrant colors and sharp focus on the central subjects.
- + Excellent rendering of light refraction and reflections through the glass.
- + Perfect adherence to all object placement requirements.
- − The base of the glass cube appears to be a mirror rather than just glass.
- − The plant behind the cube is slightly blurry compared to the foreground.
Verdict: Both models followed the prompt perfectly, including the specific lighting and object arrangement. Gemini 3 Pro Image Preview has a more convincing photographic quality with a beautiful natural environment, while Seedream 4.0 provides a cleaner, more stylized look with superior handling of glass reflections and refraction. Seedream 4.0 is slightly preferred for the clarity of the objects, although Gemini 3 Pro's realism is impressive.
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 and sectioning requirements.
- + Highly legible typography with professional hierarchy and pricing.
- + Realistic and vibrant food photography that fits the casual dining theme.
- + Clean, professional mock-up presentation on a wooden surface.
- − Nonsense filler text for descriptions.
- − Minor repetition of item names in the lists.
Seedream 4.0
- + Bold, clean sans-serif typography.
- + Vibrant food colors.
- − Failed to include menu items or pricing.
- − Poor composition with fragmented, overlapping text and images.
- − Lacks the professional layout requested in the prompt.
Verdict: Gemini 3 Pro Image Preview successfully followed all prompt instructions, creating a comprehensive and realistic menu layout with distinct sections for appetizers, pizza, and mains. Seedream 4.0 failed to create an actual menu, instead producing a collage of food and headers without specific items or structured design.
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 quality with a high level of detail in the man's face and clothing.
- + Beautiful light reflections on the wet pavement that enhance the mood.
- + Strong sense of place with the recognizable Tokyo-style taxi and background signage.
- − Missed the request for motion blur on passing cars; the vehicles are quite static.
- − The bicycle's structure is slightly incoherent near the handlebars and seat post.
Seedream 4.0
- + Successfully incorporated motion blur on the passing vehicle as requested.
- + Good focus on the 'repairing' aspect with visible tools on the ground.
- + Accurately captured the 'imperfect framing' and shallow depth of field.
- − The man's hands are anatomically incorrect and blurry.
- − The bicycle's geometry is very poor, with the frame and chain guard merging unnaturally.
- − The texture of the man's hair and face looks slightly 'mushy' compared to the sharpness of the ground.
Verdict: Gemini 3 Pro Image Preview produces a much more convincing and high-quality image with exceptional skin textures and lighting, though it fails to include the requested motion blur. Seedream 4.0 follows the motion blur instruction and includes tools for more narrative context, but it suffers from significant anatomical and structural errors in the hands and bicycle. Gemini 3 Pro is the winner for its superior realism and photographic clarity.
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 preservation of the man's facial features and specific hairstyle from the source.
- + The car interior and exterior details closely match the source Rolls Royce.
- + Dynamic composition with realistic motion blur and high-quality lighting.
- − The man appears to have three arms/hands (one on the wheel, one resting on the door, one partially visible below).
Seedream 4.0
- + Perfectly maintains the exact car from the source image at a similar angle.
- + Successfully places both the car and the man in the requested California coastline setting.
- − The man's facial features are significantly altered and lower quality compared to the source.
- − The scale of the man inside the car feels slightly off, making him look too small for the vehicle.
Verdict: Gemini 3 Pro Image Preview provides a much more convincing edit by accurately preserving the man's identity and the car's luxurious textures, though it suffers from a structural error with multiple arms. Seedream 4.0 does a great job of preserving the car's exterior, but fails to maintain the man's face and creates a less integrated, flatter composition. Gemini 3 Pro is the winner for its superior visual quality and likeness preservation.
Bald man challenge
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
- + Perfectly preserves facial features, glasses, and background from the original.
- + Highly realistic hair texture with natural waves and highlights.
- + Integrates the hair seamlessly with the original sideburns and lighting.
- − The hairline is a bit high, though it remains stylistically grounded.
Seedream 4.0
- + Successfully adds a full head of hair while preserving the rest of the image.
- + Maintains consistent lighting and background.
- − The hair texture looks slightly fuzzy and lacks the clear individual strand definition seen in Model A.
- − The hair shape is very uniform and stiff, looking less natural than Model A.
Verdict: Gemini 3 Pro Image Preview provides a significantly more realistic result with natural-looking texture, waves, and a believable integration into the wearer's existing sideburns. Seedream 4.0 successfully follows the instructions but produces a more 'helmet-like' hair shape that lacks the realistic highlights and definition found in Gemini 3 Pro.
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 adherence to text instructions with clean, white, bold typography.
- + Highly polished 3D rendering with realistic wooden textures and subtle steam effects.
- + Superior composition that includes a diorama base and complementary elements like tea and soy sauce.
- − The flag icon is placed to the left of the text rather than at the top-center as part of the text block.
Seedream 4.0
- + Accurate 45-degree isometric perspective and diorama style.
- + Effective use of the light blue background and centered layout.
- + Good sushi variety and color saturation.
- − Black text is less aesthetically pleasing for the 'cartoon' style than white text.
- − Rendering quality is lower with some noise on the rice and less refined textures.
- − The flag icon is placed strangely beneath the text and lacks the requested 'bold' impact.
Verdict: Gemini 3 Pro Image Preview is the clear winner due to its superior rendering quality and professional-grade typography. While Seedream 4.0 followed the isometric layout well, its textures are grainy and the black text feels disconnected from the overall soft 3D aesthetic achieved by Gemini.
Night Sky Transformation
Editing“Change the scene to night: a deep, dark sky with subtle, glistening stars visible behind the mountain.”
AI Judge Analysis
Nano Banana Pro
- + Excellent source preservation, keeping almost every building and tree identical to the original.
- + The starry sky is dense and realistic, following the prompt's request for 'glistening stars'.
- + Successful color grading to shift the sunset lighting to a convincing moonlit night.
- − The transition line between the mountain peak and the new sky is slightly sharp.
Seedream 4.0
- + Successfully changes the time of day to a deep, dark night.
- + Preserves the overall composition and city layout effectively.
- − The distribution of stars is very sparse compared to the prompt's request for 'glistening stars'.
- − Slightly less clarity in the textures of the foreground village compared to the original.
Verdict: Both models did an excellent job of preserving the source image while modifying the sky. Gemini 3 Pro is the winner because its star field is much more detailed and 'glistening' as requested, whereas Seedream 4.0's sky is quite empty. Gemini 3 Pro also maintained slightly better sharpness and detail in the village buildings.
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
- + Excellent caricature style with highly expressive, exaggerated features.
- + Follows all prompt elements perfectly, including dogs, hockey, and a news anchor desk.
- + Clean, vibrant illustration style with readable text.
- − Departs completely from the photographic style of the source image.
- − The subject's facial likeness is slightly more generic than Model B.
Seedream 4.0
- + Preserves the actual facial likeness and hair of the woman in the source image much better.
- + Successfully integrates the hockey, dog, and anchor desk elements in a semi-realistic setting.
- + Correctly maintains the denim shirt from the source image.
- − The 'caricature' effect is limited to just a large head, which looks a bit like a 'bobblehead' or a sticker swap.
- − Anatomical issues with the hand holding the phone (too small, warped).
- − Lower overall visual polish compared to the illustration.
Verdict: Gemini 3 Pro Image Preview provides a much more creative and fun interpretation of a 'caricature,' making it a humorous illustration that incorporates every detail of the prompt into a cohesive scene. While Seedream 4.0 does a better job of preserving the woman's actual face and the photographic nature of the source, the execution of the caricature effect is awkward and suffers from technical artifacts in the hands.
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
- + Perfect adherence to the animal list including a golden retriever, tabby kitten, bunny, and fox.
- + Excellent clarity and sharp details in the fur and eyes.
- + Balanced composition with clearly defined god rays and dew sparkles.
- − The style leans slightly towards a 3D digital illustration rather than 'hyper-photorealistic'.
- − The kitten is quite small and positioned deep in the background.
Seedream 4.0
- + Captures a more realistic photographic lighting and soft-focus aesthetic.
- + Dynamic poses that better reflect the 'playfully chasing' and 'tumbling' part of the prompt.
- + Beautiful bokeh and more realistic interaction with the environment.
- − The fox kit has anatomical issues, appearing more like a red panda/fox hybrid with a distorted body.
- − The puppy's front paw has some blurring and structural incoherence.
- − The floating dew sparkles look slightly like digital noise in some areas.
Verdict: Gemini 3 Pro Image Preview provides a cleaner, more stable image with perfect prompt adherence, though it feels a bit like a high-end digital painting. Seedream 4.0 achieves a much more convincing 'photorealistic' look with superior lighting and dynamic energy, but suffers from anatomical distortions particularly on the fox's legs and body.
Victorian Greenhouse Oasis
Text-to-Image“Hyper-photorealistic interior of a lush Victorian glass greenhouse filled with exotic tropical plants, vibrant blooming orchids, tall ferns, colorful butterflies in flight, sunlight filtering through ornate glass roof creating realistic caustics and dew on leaves, intricate iron framework visible, misty atmosphere, 8K masterpiece.”
AI Judge Analysis
Nano Banana Pro
- + Excellent adherence to the Victorian architecture request with highly detailed ironwork and expansive glass arches.
- + Rich variety of plant life including clearly identifiable orchids, ferns, and bromeliads.
- + Very high detail density across the entire frame, creating a sense of a lush, lived-in greenhouse.
- − The butterflies are scattered somewhat unnaturally and many share identical or repeated wing patterns.
- − The lighting feels a bit flat and clinical despite the 'misty' prompt, lacking deep atmospheric contrast.
Seedream 4.0
- + Superior atmospheric rendering with beautiful light rays, mist, and glistening dew drops on the leaves.
- + More realistic butterfly placement and motion blur, contributing to a sense of a captured moment.
- + Effective use of depth of field to create a more cinematic and 'photorealistic' feel.
- − The Victorian ironwork is less 'intricate' and detailed compared to the other model, appearing slightly softer.
- − The scope of the greenhouse feels smaller and less grand than requested.
Verdict: Gemini 3 Pro Image Preview excels in architectural detail and plant variety, providing a wide-angle view of a grand Victorian structure. However, Seedream 4.0 captures the 'hyper-photorealistic' and atmospheric elements of the prompt much better, with superior lighting, visible dew drops, and convincing mist through its use of depth and light rays. Seedream 4.0 is the preferred choice for its more artistic and realistic lighting and textures.
Heroic Super Hero Portrait
Text-to-Image“Hyper-photorealistic full-body portrait of a female superhero standing triumphantly on a New York skyscraper rooftop at golden sunset, wearing a classic modest superhero costume with flowing cape, chest emblem, gloves, and boots in red and blue colors, practical design, short hair, strong determined heroic expression looking into the distance, powerful confident stance with hands on hips and cape billowing dramatically in the wind, detailed urban cityscape background, warm natural sunlight with sharp shadows and fabric highlights, ultra-sharp textures on suit, hair, and concrete, 8K masterpiece, empowering family-friendly style.”
AI Judge Analysis
Nano Banana Pro
- + Excellent photographic quality and skin texture
- + Realistic integration with the urban background
- + Dynamic and natural cape movement
- − Failed the hands-on-hips pose request
- − The chest emblem 'H' is slightly generic compared to the prompt's heroic theme
Seedream 4.0
- + Perfect adherence to the 'hands on hips' pose
- + Striking golden hour lighting and silhouette effect
- + Classic superhero aesthetic that fits the 'modest costume' description well
- − Anatomical issues with the fingers on the hips
- − The chest emblem is a direct copy of the Superman logo rather than an original design
- − The face lacks the high-resolution detail seen in the competitor
Verdict: Seedream 4.0 followed the specific structural instructions much better, correctly capturing the requested 'hands on hips' pose and 'full-body' framing. However, Gemini 3 Pro Image Preview offers superior photorealism, skin textures, and overall image clarity, despite missing the specific hand placement.
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
Nano Banana Pro
- + Excellent preservation of the original subjects' features and expressions.
- + Beautifully detailed background that captures a classic European Ghibli aesthetic.
- + Clean line work and soft, warm lighting that perfectly matches the prompt.
Seedream 4.0
- + Strong watercolor/hand-painted texture feel.
- + Successfully captures the specific simplified facial style of older Ghibli films like 'Only Yesterday'.
- − Loss of almost all background detail from the source image, replaced by a simple gradient.
- − The man's hair and facial features are significantly altered from the source image.
Verdict: Gemini 3 Pro Image Preview is the clear winner as it successfully transforms the style while perfectly preserving the composition and facial expressions of the 'Distracted Boyfriend' meme. Seedream 4.0 creates a nice watercolor effect, but it fails to maintain the background context and loses too much of the original subjects' likeness.

}
AI Judge Analysis
Nano Banana Pro
- + Near-perfect preservation of the original image's fine details, skin texture, and hair strands.
- + Successfully added a natural Duchenne smile with subtle eye crinkles and slight tooth exposure.
- + The identity and facial structure remain virtually identical to the source.
- − The smile is very subtle, perhaps slightly less 'warm' than requested.
Seedream 4.0
- + Creates a very warm and engaging smile as requested.
- + Excellent rendering of teeth and mouth shape.
- − Loss of fine skin texture and freckles compared to the original image.
- − Slightly smooths out the background and hair details, failing the 'exact preserve' instruction.
- − The face becomes a bit more generic, losing some unique identity markers from the source.
Verdict: Gemini 3 Pro Image Preview is the clear winner because it successfully applied the requested edit while perfectly preserving the source image's resolution, texture, and identity. Seedream 4.0 produced a nice smile but failed the preservation constraints, resulting in a slightly blurred and smoothed appearance that lost the fine detail of the original portrait.
Golden Hour Stroll
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 adherence to hair-blowing effect with individual strands clearly defined.
- + Leaves are sharp and colorful, creating a high-contrast dynamic effect.
- + Adds subtle motion blur to the water and some leaves to enhance the sense of speed.
- − The orange maple leaves don't match the green summer trees in the background.
Seedream 4.0
- + Leaves are more color-coordinated with the existing environment.
- + Successfully applies the hair-blowing effect while maintaining original hair texture.
- − Overall image resolution and clarity are significantly lower than the source and Model A.
- − The added leaves have a low-quality, pasted-on appearance with poor edge definition.
Verdict: Gemini 3 Pro Image Preview is the clear winner as it maintains (and slightly improves) the high resolution of the source image while convincingly adding dynamic hair and leaf elements. Seedream 4.0 successfully followed the instructions, but the significant drop in image quality and blurry artifacts on the leaves make it a much weaker edit.
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 typography with correct Italian accenting.
- + Highly stylistic steam and cross-hatching detail on the cloche.
- + Strong vector aesthetic with clean linework.
- − The placement of the banner partially obscures the base of the cloche dome.
Seedream 4.0
- + Good composition with arched text creating a balanced emblem.
- + Clear separation between the logo elements (cloche, banner, and text).
- + Accurate rendering of the paper texture background.
- − The steam is simplified and lacks the artistic flair of the prompt.
- − The 'Est. 1720' text is slightly off-center within the banner.
Verdict: Both models followed the prompt closely, providing high-quality vintage logos with accurate text. Gemini 3 Pro Image Preview is preferred for its superior artistic detail in the steam and cloche rendering, which better captures the 'vintage minimalist' and 'vector emblem' style requested.
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 followed the 1-6 step sequence with accurate vector icons for each stage.
- + Excellent text rendering for all labels, names, and the main title.
- + Superior layout and composition that visualizes the mission trajectory clearly.
- − The rocket vector is slightly more detailed than the 'flat vector' request implied, though still highly effective.
Seedream 4.0
- + Used the requested NASA-inspired color palette effectively.
- + Included the names of the astronauts as supporting details.
- − Failed to provide distinct icons for all 6 steps, leaving steps 5 and 6 without unique visual representations.
- − Text rendering is messy with character bleed and poor spacing.
- − Graphic layout is disjointed and lacks the sophisticated infographic feel requested.
Verdict: Gemini 3 Pro Image Preview significantly outperformed Seedream 4.0 by following all six structural steps requested and rendering clean, professional text. Seedream 4.0 failed to provide icons for the final steps and the overall layout was poorly balanced compared to the cohesive infographic produced by Gemini 3 Pro.
