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
- + Excellent soft lighting and atmospheric dust particles
- + Clean, modern aesthetic with high-quality textures
- + Correct spatial arrangement of all components
- − The blue sphere appears to be floating unnaturally within the cube
- − The cube edges are slightly indistinct against the bright light
Wan 2.6
- + Realistic physics with the sphere resting on the bottom of the cube
- + Beautifully rendered glass reflections and caustic effects on the table
- + The weathered book adds a nice touch of realism and texture
- − The green plant is placed to the side rather than strictly behind the cube
- − The glass cube has some minor structural inconsistencies on the left edge
Verdict: Both models followed the prompt instructions very well. Nano Banana excels in lighting and clean composition, but the sphere is floating in space. Wan 2.6 provides a more grounded, realistic scene with complex glass reflections and a tangible sense of weight, making it the slightly better render.
Man and Car in California
Editing“Make a photo of the man driving the car down the California coastline”
AI Judge Analysis
Nano Banana
- + Excellent preservation of the car's model and specific details from the source image
- + Identifiable inclusion of the man's unique hairstyle (locs/bun) through the windshield
- + High-quality motion blur on the road and wheels creating a realistic action shot
- − The man is positioned slightly too far back or low in the seat, making his presence a bit subtle
Wan 2.6
- + Strong composition with palm trees adding to the California aesthetic
- + Good preservation of the car's exterior design
- + Dynamic lighting and clear background scenery
- − The man's unique features (hair and face) from the source image are not preserved, replaced by a generic person in a hat
- − The interior of the car (seats and headrests) changed significantly from the source
Verdict: Nano Banana is the clear winner because it successfully integrated the specific man from the source image, capturing his distinct hairstyle, whereas Wan 2.6 used a generic person. Nano Banana also did a superior job of preserving the exact interior and exterior details of the Rolls Royce while placing it in a convincing coastal environment.
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
- + Excellent street photography composition with natural-looking motion blur.
- + Realistic skin texture and garment details.
- + Stronger adherence to the candid street photo feel with imperfect framing.
- − The raindrops appear as static white streaks and circles that look a bit artificial up close.
- − Minor bicycle anatomy issues where the chain meets the rear wheel.
Wan 2.6
- + Superb skin texture and fine detail on the hands and face.
- + Includes physical tools on the ground which adds to the storytelling of 'repairing'.
- + Very effective use of reflections on the wet pavement.
- − The raindrops on the man's coat look like static, frozen beads of plastic.
- − The bicycle seat and rear frame have significant structural anomalies and merging parts.
- − Less motion blur from the passing car compared to the prompt's request.
Verdict: Nano Banana captures the requested 'candid street photo' aesthetic and 'motion blur' more effectively, creating a more believable atmosphere. While Wan 2.6 has impressive facial textures, it suffers from significant anatomical errors in the bicycle structure and less convincing rain effects.
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
- + Excellent detail on the engraved armor plates
- + Clear adherence to the 'braided hair' and 'faint scars' prompt
- + Strong composition with professional-looking lighting
- − The scars look a bit like surface-level digital painting rather than realistic skin depth
- − The hair beads are somewhat simplistic compared to the prompt
- − Slightly 'over-sharpened' digital look
Wan 2.6
- + Highly realistic skin texture with lifelike dirt and sweat
- + Exceptional detail on the hair beads including translucency
- + Very convincing 'battle-worn' aesthetic with frayed cloth and grimy metal
- − The bokeh sparks are a bit overwhelming in the background
- − One eye has a slight alignment issue under scrutiny
Verdict: Nano Banana produces a cleaner, more heroic-looking illustration with very ornate armor, while Wan 2.6 delivers a much more visceral and lifelike interpretation. Wan 2.6 is the winner for its superior texture work on the skin, the tangible quality of the beads in the hair, and the realistic wear on the leather and cloth layers.
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
- + Excellent text rendering with almost perfect spelling in the headers and items.
- + Precise adherence to the grid layout with a clean, professional aesthetic.
- + High-quality, distinct food photography that matches the category headers.
- − Minor spelling errors like 'APPETIERS' and 'Margheiita'.
- − The food photos represent breakfast items (pancakes) which conflict slightly with the casual dinner menu items listed below.
Wan 2.6
- + Modern, vibrant graphic accents in the corners and dividers.
- + Good use of white space and professional sans-serif typography.
- − Significant text hallucinations and garbled characters in the body text.
- − Unordered layout where common headers like 'PIZZA' are repeated in confusing locations.
- − Artifacts in the food photos, such as unnatural liquid and clipping.
Verdict: Nano Banana is the clear winner as it produces a functional, legible menu with a professional grid layout and high-quality imagery. While Wan 2.6 has some nice graphic design flourishes, its text is largely illegible and the layout is disorganized compared to the clean, structured output of Nano Banana.
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
- + Excellent typography with clean, glowing fire effects
- + Includes the starburst price tag accurately formatted
- + High clarity and photorealistic texture on the food components
- − The composition feels slightly static compared to the second model
- − The background is a bit more generic with simple sparks rather than smoke
Wan 2.6
- + Dynamic composition with a great sense of motion and smoke
- + Very impressive fiery text effect with realistic flames
- + Stronger atmospheric lighting matching the fiery theme
- − The price starburst looks like a cartoon sticker rather than a glowing integrated effect
- − The burger patty and cheese are slightly less detailed than in Model A
Verdict: Both models followed the prompt exceptionally well, but Nano Banana is the winner due to better adherence to the text rendering requirements, specifically the glowing starburst price tag. While Wan 2.6 provided a more dynamic and smoky atmosphere, its price tag felt like a clashing graphical overlay rather than a photorealistic part of the scene.
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
- + Excellent text rendering with no spelling errors in any of the items.
- + Clean and professional composition with atmospheric background lighting.
- + Highly accurate adherence to all requested menu items and prices.
- − The handwriting looks slightly too uniform and digitised, lacking the gritty chalk texture requested.
Wan 2.6
- + Superb chalk texture with realistic dusty residue and varying stroke pressure.
- + The handwriting feels more authentic and manual, capturing the requested natural variations and slant.
- − Repeats the prices on separate lines, which was not in the prompt.
- − Contains minor punctuation errors and a more cluttered layout.
Verdict: Nano Banana is the clear winner for text accuracy, correctly rendering every single word and price from the prompt without error. However, Wan 2.6 captures the requested 'chalk texture' and 'handwritten style' much more realistically, despite its repetition of the price tags and slightly messier layout.
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
- + Successfully preserved the exact person and vitiligo patterns.
- + Captured the distinct texture and pattern of the scarf well.
- − Failed to fully dress the subject, leaving most of the torso bare.
- − The coat is awkwardly draped behind the shoulder rather than worn.
Wan 2.6
- + Expertly fully dressed the person in the requested outfit while maintaining the base body shape.
- + Accurately included the sunglasses and scarf details.
- + Successfully preserved the original face and background.
- − The scarf pattern is slightly simplified compared to the source image.
- − The sunglasses style is a generic modern wayfarer instead of the specific browline style in the source.
Verdict: Wan 2.6 is the clear winner as it followed the core instruction to 'dress' the person in the outfit, whereas Nano Banana merely draped items behind the person, leaving the torso exposed. Wan 2.6 also demonstrated better prompt adherence by including the accessory (sunglasses) while maintaining the identity of the person from Image 1.
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
- + Excellent texture on the capybara's fur and the leather jacket
- + Strong cinematic lighting that matches the New York night atmosphere
- + The passenger's bored expression perfectly matches the prompt requirements
- − The passenger appears to be in the front passenger seat rather than the back seat
- − The capybara's paws are merged awkwardly with the steering wheel
Wan 2.6
- + Correctly places the human passenger in the back seat
- + Captures the 'professional' expression and pose of the capybara well
- + High level of detail in the background city lights and rain effects on the window
- − The passenger's hand holding the phone has significant anatomical distortions
- − The interior of the taxi appears overly worn or dirty compared to the 'realistic' request
Verdict: Wan 2.6 adhered better to the spatial requirements of the prompt by placing the passenger in the back seat, whereas Nano Banana placed her in the front. However, Nano Banana produced a more aesthetically pleasing image with better lighting and a more convincing bored expression on the passenger, despite the seating error.
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
- + Excellent text rendering with no spelling errors
- + Clean and symmetrical composition
- + Highly detailed and intricate thorn and web border
- − Lighting is a bit flat compared to the other model
- − The jack-o-lantern looks slightly like a 3D asset placed on a background
Wan 2.6
- + Atmospheric cinematic lighting with strong orange glows
- + Creative gold-glitter texture on the main title
- + More organic and spooky tree designs
- − Minor text artifacts in the banner sentence
- − The border is less cohesive than Model A's
Verdict: Both models followed the prompt exceptionally well, capturing all text requirements accurately. Nano Banana is preferred for its professional layout, superior text clarity, and intricate border detail, whereas Wan 2.6 offers a slightly moodier atmosphere with more painterly lighting.
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
- + Excellent texture matching the existing beard
- + Perfectly preserved all original facial features and glasses
- + Natural integration near the ears and forehead
- − The hair on top is slightly wispy compared to the 'full and thick' request
Wan 2.6
- + Successfully added a very thick and dense head of hair
- + Matches the lighting and overall color profile well
- − Noticeably altered the person's face shape and eyes
- − The hair looks slightly like a wig due to the volume and edge blending
- − Slight distortions to the frames of the glasses
Verdict: Nano Banana followed the instruction while perfectly preserving the subject's identity, whereas Wan 2.6 subtly changed the facial features and eyes during the edit. Nano Banana's results look more like a natural progression of the man's existing hair texture, making it the more successful edit.
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
- + Perfectly rendered, clean bold text with correct spatial positioning
- + Excellent adherence to the 'cartoon' style with high-clarity PBR materials
- + Beautifully detailed diorama base with organic wood grain and curved edges
- − The salmon texture is slightly repetitive across the three pieces
Wan 2.6
- + Strong isometric composition with a clear diorama height
- + Crisp lighting and shadow work resulting in great depth
- + Good variety in the sushi types including shrimp
- − The text is white and lacks a clean 'design' feel compared to Model A
- − The text and flag are grouped somewhat awkwardly in the header space
Verdict: Nano Banana is the clear winner as it perfectly executes the header-style text layout and provides a more polished, high-end 3D cartoon aesthetic. While Wan 2.6 captures the isometric diorama feel well, Nano Banana's typography rendering and the refined 'clay-like' PBR textures of the sushi itself are superior and more visually appealing for this specific prompt.
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
- + Excellent adherence to all prompt elements including dog, hockey, and news anchor set.
- + Superior facial likeness preservation to the source image within the caricature style.
- + High level of humorous exaggeration with the muscular arm and dog in a hockey helmet.
- − Some text rendering at the bottom of the image is garbled.
- − The anatomy of the hand on the dog's head is slightly warped.
Wan 2.6
- + Clean, vibrant artistic style with good composition.
- + Successfully incorporates all requested elements: dog, hockey stick/puck, and news studio.
- − The facial likeness to the source image is weak and looks like a generic cartoon character.
- − Less 'exaggerated and humorous' than the other model, feeling more like a standard illustration.
Verdict: Nano Banana is the clear winner as it successfully captures the facial likeness of the person in the source image while leaning into the 'humorous and exaggerated' request with creative details like the dog's helmet and the anchor's bicep. Wan 2.6 provides a high-quality illustration, but the character does not closely resemble the subject of the source image and feels less like a true caricature.
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
- + Excellent character symmetry and clean, illustrative quality
- + Strong adherence to all requested species with clear individual traits
- + Beautifully rendered flowers and soft bokeh lighting
- − Looks more like a digital painting than a 'hyper-photorealistic' scene
- − The animals are mostly posing for the camera rather than 'tumbling' or 'playfully chasing'
Wan 2.6
- + Captures a much more dynamic sense of movement and 'tumbling' action
- + Superior lighting with realistic dew sparkles and atmospheric depth
- + More photorealistic fur textures and natural-looking interactions between the animals
- − The fox kit's anatomy is slightly messy where its body meets the ground
- − The 'tabby' markings on the kitten are a bit muddy compared to Model A
Verdict: Wan 2.6 captures the spirit of the prompt much more effectively by showing the animals in motion, chasing butterflies and tumbling, whereas Nano Banana provides a static though very cute group portrait. Wan 2.6 also hits the 'hyper-photorealistic' requirement more accurately, whereas Nano Banana leans into a stylized digital art aesthetic.
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
- + Excellent source preservation, maintaining the original faces and poses exactly.
- − Failed to apply the requested edit; it looks like a photograph with a slight blur filter.
- − Complete lack of Studio Ghibli or illustrative style.
- − Colors and textures do not match the prompt's request for 'hand-painted' or 'pastel'.
Wan 2.6
- + Successfully transforms the photo into a beautiful watercolor illustration style.
- + Strong adherence to the Studio Ghibli aesthetic with soft lines and warm, nostalgic lighting.
- + Accurately replicates the poses, clothing, and composition of the source image while stylizing it.
- − The faces, while recognizable, are generalized into the anime style, losing some specific facial features of the original people.
- − The background is significantly simplified and washed out.
Verdict: Nano Banana failed the image editing task, providing what appears to be the original photograph with almost no noticeable changes. Wan 2.6 followed the instructions perfectly, creating a high-quality watercolor illustration that captures the Studio Ghibli aesthetic while maintaining the recognizable structure of the 'distracted boyfriend' meme.
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
- + Successfully added wind-blown hair and autumn leaves.
- + Preserved the identity and pose of the subject and dog very well.
- + The leaves have varied colors (orange, yellow) which adds visual interest.
- − Some leaves appear to be floating in front of/overlapping the dog in a way that looks like a digital sticker.
- − The dog's tail has a slightly unnatural shape compared to the original.
Wan 2.6
- + Excellent hair motion that looks natural and windswept.
- + Preserved the original source image details with high fidelity.
- + Green leaves match the summer setting of the original photo better than autumn leaves.
- − Fewer leaves added compared to Model A, making the 'motion' feel slightly less dynamic.
- − Some blurring on the dog's tail is a bit inconsistent with the rest of the dog's sharpness.
Verdict: Both models followed the instructions well, adding convincing wind effects to the hair and flying leaves. Wan 2.6 is the subtle winner because it chose green leaves that match the lush summer environment of the source image, whereas Nano Banana changed the season of the leaves to autumn, which felt slightly less cohesive with the green trees in the background.
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
- + Perfectly renders the text with the specific requested accent on 'Caffè'.
- + Excellent composition with the banner integrated into a cohesive circular emblem.
- + Captures the 'vintage minimalist' and 'vector emblem style' more authentically.
- − The steam effect is inside/on the cloche rather than rising from it.
Wan 2.6
- + Logical placement of steam rising from the top of the cloche.
- + Good use of subtle background texture around the edges to convey a vintage feel.
- + Sharp, clean typography for the main name.
- − The banner for 'Est. 1720' is oddly placed and feels like an afterthought rather than a design element.
- − Shadowing on the cloche is a bit heavy for a minimalist vector logo.
Verdict: Nano Banana is the superior logo design because it creates a unified, balanced emblem where all elements—the cloche, the name, and the banner—work together harmoniously. While Wan 2.6 rendered the steam more logically, its composition was weaker, particularly with the awkward placement of the date banner. Nano Banana also accurately included the accent mark in 'Caffè', showing better attention to the specific text prompt.
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
- + Followed all 6 requested steps of the infographic chronologically.
- + Excellent text rendering and typography for the labels and titles.
- + Clean flat-vector style with professional iconography that matches the prompt exactly.
- − The iconography for the Lunar Module is slightly abstract compared to the other icons.
- − The glowing circles around icons introduce a light effect that slightly deviates from a pure flat-vector look.
Wan 2.6
- + Matches the requested NASA-inspired color palette well.
- + Creative use of silhouettes for the crew members.
- − Completely failed to include the requested 6-step infographic content.
- − Text rendering is messy with characters overlapping the silhouettes.
- − Composition is mostly empty space and lacks the 'infographic' nature requested.
Verdict: Nano Banana followed the complex prompt instructions perfectly, creating a logical 6-step infographic with clear labels and era-appropriate icons. Wan 2.6 failed almost every structural requirement of the prompt, providing only a title and crew silhouettes while ignoring the actual mission steps. Nano Banana is the clear winner for both adherence and design quality.
