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 2
- + Excellent photorealism and texture detail on the wooden table and the glass cube.
- + Clear, legible text on the book spine.
- + Accurate representation of glass reflections and refraction.
- − The glass cube looks more like a small aquarium or enclosure without a top face.
- − The scale of the plant in the background is quite large compared to the cube.
Seedream 5.0 Lite
- + The glass cube is more clearly defined as a solid geometric object.
- + Pleasant, warm lighting that matches the 'soft window light' request.
- + Clean composition with a consistent soft focus on the background.
- − The blue sphere looks slightly matte/flat compared to the surrounding environment.
- − Lower overall detail in textures compared to the competitor.
Verdict: Both models followed the prompt instructions perfectly, including all requested objects and their spatial relationships. Nano Banana 2 achieved a higher level of photorealism and impressive text rendering on the book, while Seedream 5.0 Lite produced a cleaner, more balanced geometric composition with a more natural-looking glass cube.

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 2
- + Excellent adherence to the 'imperfect framing' and 'candid' street photography aesthetic
- + Very realistic text rendering on Japanese signage
- + Captures a wider range of the prompt's environment including pedestrians and detailed wet pavement
- − The anatomy of the wrench and hands is slightly garbled upon close inspection
- − Motion blur on the car is less pronounced than requested
Seedream 5.0 Lite
- + Stronger shallow depth of field effect as requested
- + Impressive natural skin texture and facial details
- + Better execution of motion blur on the passing vehicle
- − The bicycle frame geometry is physically impossible
- − The image feels more like a staged portrait than a 'candid street photo' with 'imperfect framing'
Verdict: Nano Banana 2 captures the requested 'candid' and 'imperfect' street photography aesthetic much better, providing a rich, believable environment with accurate Japanese signage. Seedream 5.0 Lite has superior skin textures and motion blur, but the physical logic of the bicycle is broken and the composition feels too clean for the specific 'candid' prompt.
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.”
AI Judge Analysis
Nano Banana 2
- + Excellent adherence to textural details like dirt, grime, and blood on the skin.
- + Incredibly high level of detail on the engraved plate armor and ornate engravings.
- + Strong atmosphere with realistic lighting and particle effects (sparks).
- − The character's hand on the sword hilt appears slightly distorted and muddy in detail.
Seedream 5.0 Lite
- + Beautiful, clean composition with soft, cinematic lighting.
- + Very clear depiction of the 'braided hair with small beads' part of the prompt.
- + Sharp facial features and expressive, lifelike eyes.
- − Lacks the 'battle-worn' and 'dirt' aesthetic requested, appearing too clean and polished.
- − Texture on the cloth underlayer feels less detailed compared to Model A.
Verdict: Nano Banana 2 captures the 'battle-worn' and 'gritty' essence of the prompt far better than Seedream 5.0 Lite, which produces a very clean, high-fantasy look that misses the requested dirt and grime. Nano Banana 2 also excels in the intricate engravings of the armor, whereas Seedream 5.0 Lite focuses more on a soft, cinematic portrait style.
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 2
- + Excellent adherence to the grid layout with multiple vibrant food photos.
- + Highly legible text with professional categorization and realistic descriptions.
- + Superior visual appeal and realistic 'casual dining' professional aesthetic.
- − Small text descriptions contain minor spelling errors (e.g., 'somon', 'oamon').
Seedream 5.0 Lite
- + Clear, bold sans-serif fonts that are easy to read at a glance.
- + Very clean white background and minimalist structure.
- + Accurate pricing and bold header labels.
- − Wasted space with only two items per section, making it look sparse.
- − Lacks the sophisticated layout requested; feels more like a template than a finished design.
- − Visual variety in food photos is lower compared to Model A.
Verdict: Nano Banana 2 is the clear winner as it produces a comprehensive, professional-grade menu with a complex grid layout and high-quality food photography that perfectly matches the prompt. Seedream 5.0 Lite is too simplistic, leaving significant white space and lacking the professional polish and categorization density seen in the other model.
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 2
- + Perfect preservation of the original face, glasses, and background
- + Seamless blend between the new hair and the existing facial hair
- + Highly realistic texture and salt-and-pepper coloring that matches the beard
- − None
Seedream 5.0 Lite
- + Excellent hair texture and realistic thickness
- + Maintains the overall composition and lighting well
- − Slightly alters facial features, making the eyes appearing slightly different than the source
- − The hairline/forehead shape is a bit more modified compared to the original bone structure
Verdict: Nano Banana 2 is the clear winner as it successfully adds a full head of hair while perfectly preserving every detail of the original face and background. Seedream 5.0 Lite also does a great job with the hair texture, but it introduces subtle changes to the eye area and facial structure that deviate from the source image.
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 2
- + Excellent photorealistic PBR materials for the sushi and wooden platter.
- + High-clarity text rendering with a clean font.
- + Highly detailed and realistic representation of various sushi types.
- − The 'cartoon' style requested in the prompt is missing in favor of realism.
- − The scene is busier than the requested 'minimal' diorama.
- − Slightly deviates from the 'isometric' perspective with more of a standard bowl-on-table angle.
Seedream 5.0 Lite
- + Closer adherence to the 45° isometric perspective.
- + Perfectly captures the 'cartoon' and 'soft refined texture' aesthetic.
- + Cleaner, more minimal composition on a simple raised diorama base.
- − Text layout is somewhat clunky compared to model A.
- − The sushi models are very simplistic and lack the 'realistic PBR' quality requested.
- − The flag icon is placed to the side rather than 'below it' as part of the center-top block.
Verdict: Nano Banana 2 produces a stunningly realistic image with high-quality textures and professional typography, but it fails to capture the 'cartoon' aspect of the prompt. Seedream 5.0 Lite adheres much better to the isometric diorama layout and cartoon style, though the sushi itself is less visually impressive. Nano Banana 2 is the winner for its superior rendering quality and precise text execution.
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 2
- + Perfect source preservation of the village and terrain.
- + Realistic Milky Way effect in the starry sky.
- + Accurate lighting adjustment on the mountain peak.
- − The sky has a slightly hazy/diffuse quality compared to the sharp mountain.
Seedream 5.0 Lite
- + Excellent preservation of the original mountain and village details.
- + Clean, dark sky with glistening stars.
- + Accurate lighting transition from sunset to night.
- − Slightly less atmospheric variety in the sky compared to the Milky Way effect in Model A.
Verdict: Both models performed exceptionally well on this task, maintaining near-perfect pixel-level consistency with the source image's village and mountain structures while convincingly changing the sky and lighting. Nano Banana 2 includes a subtle Milky Way effect which adds a touch of realism, while Seedream 5.0 Lite provides a very clean and classic night sky; both are top-tier edits.
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 2
- + Captures the subject's likeness effectively in a classic caricature art style.
- + Excellent adherence to all prompts, including clever text integration like 'W-K9 NEWS'.
- + Highly creative composition with multiple dogs and humorous hockey-related details.
- − The hand holding the microphone has an extra finger/anatomical confusion.
- − The perspective of the 'held paper' effect makes the image slightly more cluttered.
Seedream 5.0 Lite
- + Clean, digital illustration style with high resolution.
- + Preserves the subject's clothing (denim jacket over black top) very accurately.
- + Simple and clear composition that clearly depicts each element of the prompt.
- − The art style is a generic 'avatar' or 'emoji' style rather than a humorous caricature.
- − The expression is less 'exaggerated and humorous' as requested compared to Model A.
- − The hockey stick and hand interaction is a bit stiff and lacks the dynamic feel of a caricature.
Verdict: Nano Banana 2 is the clear winner as it truly understood the 'caricature' and 'humorous' aspects of the prompt, providing a lively scene with clever puns and expressive features that still resemble the source person. Seedream 5.0 Lite produced a high-quality digital avatar, but it feels more like a standard cartoon portrait than an exaggerated caricature and lacks the creative flair seen in the news headlines and multiple dog interactions of the first model.
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 2
- + Excellent adherence to the 'photorealistic' prompt with natural lighting and fur textures.
- + Complex composition with all four animals clearly visible and distinct.
- + Beautifully rendered golden hour light with realistic god rays and dew drops.
- − The fox kit has slightly strange anatomy on its front paws.
- − The sheer number of elements in the foreground makes the bottom edge feel a bit cluttered.
Seedream 5.0 Lite
- + Adhered well to the 'tumbling together' part of the prompt with a playful pileup.
- + The lighting effects and dew sparkles are very pronounced and magical.
- + Very clean and expressive character designs that lean into a cute aesthetic.
- − Failed the 'photorealistic' requirement, opting for a 3D animation/stylized look instead.
- − The sun is significantly blown out in the background, losing detail.
Verdict: Nano Banana 2 followed the prompt much more accurately by providing a photorealistic style as requested, whereas Seedream 5.0 Lite produced a stylized, cartoon-like image. Nano Banana 2 also better handled the anatomy of the golden retriever and kitten, creating a more convincing natural scene.
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 2
- + Excellent hand-painted, watercolor texture that aligns perfectly with Ghibli's background art style.
- + Highly creative reimagining of the background while maintaining the original composition.
- + The soft pastel color palette and gentle lighting perfectly meet the prompt's aesthetic requirements.
- − The facial expressions are slightly softened, losing some of the high-intensity 'shock' from the original meme.
Seedream 5.0 Lite
- + Strong preservation of the original street background while applying a cel-shaded filter.
- + The character faces are very clean and clearly evoke modern anime styles.
- + Good preservation of the original facial expressions and body language.
- − The background feels more like a blurred photo filter than a hand-painted Ghibli illustration.
- − The lighting lacks the 'dreamy' and 'warm' qualities requested in the prompt.
Verdict: Nano Banana 2 is the clear winner as it successfully transforms the entire image into a cohesive work of art, featuring the hand-painted watercolor textures and warm, nostalgic lighting characteristic of Studio Ghibli. Seedream 5.0 Lite applies a competent anime filter to the characters but fails to transform the background into a convincing illustration, leaving it looking like a digitally blurred photograph.
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 2
- + Perfect text rendering for all requested and unrequested text.
- + High-quality vector emblem style with intricate vintage flourishes.
- + Excellent prompt adherence including the cloche, steam, and banner.
Seedream 5.0 Lite
- + Clean minimalist interpretation of the request.
- + Correct placement of requested elements like the cloche and banner.
- + Strong use of warm brown and cream tones.
- − Incorrect character used in 'Caffê' (circumflex instead of grave accent).
- − The composition feels slightly empty compared to a professional logo.
Verdict: Nano Banana 2 produced a superior result that looks like a finished professional logo, handling complex text and ornamentation perfectly. Seedream 5.0 Lite followed the prompt well but lacked the 'Est. 1720' text on the banner (it placed it below) and included a spelling error on the main title.
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 2
- + Excellent adherence to the color palette and flat-vector style.
- + Almost perfect text rendering, including the names 'Armstrong', 'Aldrin', and 'Collins'.
- + Sophisticated graphic design layout with consistent line weights and icons.
- − Includes a fourth unidentified astronaut silhouette in the crew section.
- − The 'Lunar Module' icons are slightly abstracted compared to technical illustrations.
Seedream 5.0 Lite
- + Accurate crew count (three astronauts) and correct naming.
- + Clear separation of the six requested steps with numerical labels.
- + Good use of negative space for a 'space' feel.
- − Typographical error in 'TRANSLUMAR' (should be Translunar).
- − The Saturn V icon lacks the detail and proportions of the actual rocket.
- − Layout is less 'modern infographic' and more 'basic template' compared to the other model.
Verdict: Nano Banana 2 is the superior choice because it captures the 'modern vector infographic' aesthetic perfectly with professional-grade iconography and design balance. While Seedream 5.0 Lite followed the crew count more accurately, it failed on spelling ('TRANSLUMAR') and the overall visual sophistication required by the prompt.
