The strongest take from each model on every shared challenge, with the AI judge's read.

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.”

FLUX.1 [dev]
Nano Banana Pro

AI Judge Analysis

FLUX.1 [dev]

  • + Beautiful refracton and lighting effects in the glass cube
  • + High-quality leather texture on the red book
  • + Succulent-like plant creates a clean, modern aesthetic
  • The sphere appears to be floating mid-air inside the cube without support
  • The plant is placed to the side rather than directly behind the cube as requested
  • The glass cube has internal vertical struts that weren't in the prompt

Nano Banana Pro

  • + Perfect adherence to spatial instructions with the plant visible through the glass
  • + Realistic scale and physics with the sphere resting on the bottom
  • + Exceptional photographic quality with natural window light and film-like grain
  • The sphere is slightly smaller than 'small blue sphere' might imply compared to the large cube

Verdict: Nano Banana Pro followed the prompt's spatial instructions much more accurately, correctly placing the plant behind the glass cube and resting the sphere on the base. While FLUX.1 [dev] produced a very clean and stylized image, Nano Banana Pro's output feels more like a real photograph with superior lighting and texture details on the wood and book.

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.”

FLUX.1 [dev]
Nano Banana Pro

AI Judge Analysis

FLUX.1 [dev]

  • + Excellent handling of shallow depth of field and bokeh effects
  • + Strong facial detail and skin texture on the subject
  • + Consistent lighting and rain effects across the scene
  • The man appears to be leading/holding the bike rather than actively 'repairing' it
  • The composition feels a bit too staged and clean for a 'candid' prompt

Nano Banana Pro

  • + Perfectly captures the 'candid' and 'imperfect framing' requested in the prompt
  • + More accurate depiction of the 'repairing' action
  • + Realistic film-like grain and color grading that matches the 'no stylization' request
  • Slightly less background motion blur from the passing cars compared to the foreground detail
  • Low-resolution artifacts on some background text and umbrellas

Verdict: Nano Banana Pro wins this challenge by better adhering to the specific 'candid' and 'repairing' aspects of the prompt, resulting in an image that looks like a genuine street photograph from Tokyo. FLUX.1 [dev] produced a higher quality, more cinematic portrait, but the subject's pose was less relevant to the task of repairing the bicycle and felt slightly more artificial.

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.”

FLUX.1 [dev]
Nano Banana Pro

AI Judge Analysis

FLUX.1 [dev]

  • + Excellent photographic realism in the eyes and skin texture.
  • + Strong use of bokeh and shallow depth of field for a cinematic look.
  • + Clean, professional lighting setup.
  • Missed the request for beads in the hair braids.
  • The character looks too clean and 'model-like' for a battle-worn description.
  • The armor lacks the intricate engraving mentioned in the prompt.

Nano Banana Pro

  • + Perfect adherence to all prompt details including beads, engravings, and scars.
  • + Conveys a realistic 'battle-worn' aesthetic with believable dirt and wear.
  • + Highly detailed texture on leather straps and armor.
  • Composition feels slightly more crowded with the torch in frame.
  • Minor artifacts in the bokeh sparks in the background.

Verdict: While FLUX.1 [dev] produced a stunning, high-fidelity portrait, it ignored several key descriptive elements like the beads and the battle-worn skin. Nano Banana Pro followed the prompt much more accurately, successfully capturing the gritty texture of a scarred warrior and the ornate details of the armor.

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.”

FLUX.1 [dev]
Nano Banana Pro

AI Judge Analysis

FLUX.1 [dev]

  • + Elegant and professional minimalist layout.
  • + High clarity in the food photography elements.
  • + The design truly feels like a modern casual dining menu with sophisticated whitespace.
  • Failed to include a 'pizza' section as requested in the headers.
  • Text legibility for item descriptions is poor and contains gibberish.
  • Missed the 'photo grid' instruction, instead using a floating decorative arrangement.

Nano Banana Pro

  • + Perfectly adhered to the layout request with a photo grid and specific sections for appetizers, pizza, and mains.
  • + Strong use of bold sans-serif fonts and vibrant colored accents for categorizing.
  • + Much more readable text labels compared to the other model.
  • The 'Chicken Pizza' photo clearly shows pasta, creating a logical inconsistency.
  • Overall aesthetic is slightly more generic or crowded compared to a high-end minimalist design.

Verdict: Nano Banana Pro followed the structural prompt instructions much more closely, successfully implementing the 'grid' layout and all requested sections (Appetizers, Pizza, Mains). While FLUX.1 [dev] produced a more sophisticated and aesthetically pleasing minimalist design, it ignored several key programmatic requirements of the prompt and has less legible text.

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.”

FLUX.1 [dev]
Nano Banana Pro

AI Judge Analysis

FLUX.1 [dev]

  • + Excellent photorealistic texture on the burger components
  • + Clean, professional typography formatting
  • Completely missed the primary 'MAGIC BURGER' text
  • Lacks the requested 'starburst' for the price
  • The background is static fire rather than a 'fiery background with embers'

Nano Banana Pro

  • + Perfect adherence to all text requirements including 'MAGIC BURGER'
  • + Dynamic, tilted composition conveys a strong sense of motion
  • + Accurately rendered the fiery starburst and ember-filled background
  • Typography has slight glowing artifacts around letter edges

Verdict: Nano Banana Pro is the clear winner as it followed every instruction in the prompt, including the specific title text and the starburst element which FLUX.1 [dev] omitted entirely. While FLUX.1 [dev] produced a clean image, it failed on several key prompt requirements, whereas Nano Banana Pro captured the dynamic energy and 'fiery' theme perfectly.

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.”

FLUX.1 [dev]
Nano Banana Pro

AI Judge Analysis

FLUX.1 [dev]

  • + Excellent text legibility and accuracy
  • + Rich, opaque chalk-like texture in the lettering
  • + Balanced vertical composition
  • Text styling looks more like a digital brush than organic chalk
  • Background and frame are somewhat flat and less atmospheric

Nano Banana Pro

  • + Highly realistic chalkboard texture with authentic smudge marks
  • + Warm, cozy café atmosphere in the background
  • + Captures the slight slant and natural variations requested in the prompt
  • Text rendering is slightly less crisp than Image A
  • The 'p' in 'Specials' is slightly deformed

Verdict: Both models followed the complex prompt instructions near perfectly, including the specific date and menu items. FLUX.1 [dev] provides a very clean, high-contrast board that is easy to read, whereas Nano Banana Pro excels at creating a believable, immersive environment with realistic chalk smudges and depth that feels more like a real café.

The Reversed Rodeo

Text-to-Image

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

FLUX.1 [dev]
Nano Banana Pro

AI Judge Analysis

FLUX.1 [dev]

  • + High visual quality and lighting
  • + Cinematic composition with good use of depth of field
  • Completely failed the semantic prompt by putting the astronaut on top
  • Anatomy issues with the horse's additional leg

Nano Banana Pro

  • + Successfully followed the difficult spatial prompt of the horse being on top
  • + Creative interpretation with the horse wearing a cape and the astronaut lifting it
  • + Richly detailed background elements like the satellite and galaxies
  • Visual style is slightly less cinematic and more like a photocomposite
  • Astronaut hands and horse hooves have some blending artifacts

Verdict: While FLUX.1 [dev] produced a more polished and aesthetically pleasing image, it failed the specific logic of the prompt, showing the traditional 'astronaut riding a horse' scene. Nano Banana Pro successfully followed the instruction to place the horse on top, creating a surreal and humorous image that adhered to every part of the request.

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.”

FLUX.1 [dev]
Nano Banana Pro

AI Judge Analysis

FLUX.1 [dev]

  • + Excellent character rendering with sharp fur details and clear facial features.
  • + The capybara's expression is very professional and human-like as requested.
  • + High aesthetic quality with beautiful bokeh lighting.
  • Composition error: the woman is sitting in the front passenger seat instead of the back seat.
  • The perspective is tight and excludes some environmental details of the taxi.

Nano Banana Pro

  • + Perfect adherence to the scene layout with the woman correctly placed in the back seat.
  • + Realistic inclusion of taxi-specific details like the fare meter and dashboard.
  • + More authentic street-level atmosphere and lighting.
  • The woman's hand holding the phone has significant anatomical distortions.
  • Image quality is slightly noisier and less sharp compared to Model A.

Verdict: Nano Banana Pro captures the prompt's spatial requirements much better, placing the businesswoman in the back seat and including realistic taxi equipment. While FLUX.1 [dev] has superior lighting and character detail, it failed a key compositional instruction by placing the passenger in the front seat. Overall, Nano Banana Pro is the winner for its superior prompt adherence and storytelling accuracy.

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.”

FLUX.1 [dev]
Nano Banana Pro

AI Judge Analysis

FLUX.1 [dev]

  • + Clean vector-style illustration with striking orange and black contrast
  • + Excellent thorn border detail
  • + Accurate rendering of specific event details
  • Major spelling errors in the title text
  • Failed to include spider webs in the border
  • The 'You are invited' text is not on a scroll banner as requested

Nano Banana Pro

  • + Perfect text rendering for all lines of the invitation
  • + Stronger adherence to the 'vintage parchment' and 'moody sky' stylistic prompts
  • + Includes all requested elements like webs, thorns, and the scroll banner
  • The parchment edges appear slightly more digital than authentic
  • Slight overlap of trees and text elements

Verdict: Nano Banana Pro is the clear winner as it followed every instruction, including complex layout requirements like placing specific text on a scroll banner. FLUX.1 [dev] struggled significantly with the text content, resulting in illegible titles and missing key thematic elements like the spider webs.

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.”

FLUX.1 [dev]
Nano Banana Pro

AI Judge Analysis

FLUX.1 [dev]

  • + Excellent soft 3D textures and lighting that suit the 'cartoon miniature' style.
  • + Creative incorporation of cherry blossom branches as diorama elements.
  • Text rendering is poor, with 'SUSHI' misspelled as 'SUSH CATON' and messy characters at the top.
  • The diorama base is very plain and lacks the requested wooden or refined platform feel.

Nano Banana Pro

  • + Perfect text rendering for both 'JAPAN' and 'SUSHI' along with a clean flag icon.
  • + Higher variety and complexity in the miniature models, including wasabi, ginger, and soy sauce.
  • + Precise adherence to the 45-degree isometric perspective and diorama base request.
  • The lighting is a bit flat compared to the soft, atmospheric glow of the other model.

Verdict: Nano Banana Pro is the clear winner as it followed every instruction in the prompt perfectly, specifically the text rendering and the structure of the diorama base. While FLUX.1 [dev] produced more aesthetically pleasing soft lighting, it failed on the text elements and provided a very repetitive sushi set.

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.”

FLUX.1 [dev]
Nano Banana Pro

AI Judge Analysis

FLUX.1 [dev]

  • + Excellent adherence to the 'golden sunrise' and 'glow' lighting request
  • + Consistent stylized character design across all four animals
  • + Whimsical and dreamlike composition with a very soft aesthetic
  • Failed to include a tabby kitten, instead showing two puppies or similar canine hybrids
  • The style is very much a 3D animation/cartoon style rather than 'hyper-photorealistic'
  • The fox and bunny characters look more like toys than animals

Nano Banana Pro

  • + Successfully included all four distinct animal types: puppy, kitten, bunny, and fox
  • + Achieved a much higher level of realism in fur texture and anatomical detail
  • + Captured the 'playfully chasing' action through dynamic poses and mid-air movement
  • The scale of the kitten in the background is slightly off compared to the bunny
  • The 'god rays' are a bit literal and heavy-handed in the upper center

Verdict: Nano Banana Pro is the clear winner as it followed the complex prompt requirements entirely, including all four specific animals while maintaining a believable (though still cute) photorealistic style. FLUX.1 [dev] failed to generate a kitten and opted for a highly stylized CGI/cartoon look that ignored the 'hyper-photorealistic' instruction.

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.”

FLUX.1 [dev]
Nano Banana Pro

AI Judge Analysis

FLUX.1 [dev]

  • + Clean vector emblem style
  • + Well-balanced monochromatic color palette
  • Significant spelling errors in the main name ('Flariláan')
  • Spelling error in the banner ('RESEAURANT')
  • Included extra hallucinated numbers ('11011' and '1941')

Nano Banana Pro

  • + Perfect text rendering for both the main name and the date
  • + Excellent vintage texture and cross-hatching detail
  • + Beautifully stylized steam and banner integration
  • None

Verdict: Nano Banana Pro followed the prompt perfectly, delivering exact text and a high-quality vintage aesthetic. FLUX.1 [dev] failed significantly on typography, misspelling every line of text except for the date and adding random numbers that weren't 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.”

FLUX.1 [dev]
Nano Banana Pro

AI Judge Analysis

FLUX.1 [dev]

  • + Excellent aesthetic adherence to the muted navy and light gray palette.
  • + Consistent, minimalist flat-vector icons along the bottom footer.
  • + Clean composition with a spacious, professional feel.
  • Text is largely gibberish and fails most labels requested.
  • Includes nonsensical planetary objects like Saturn-like rings that aren't relevant to Apollo 11.
  • The layout of the steps is confusing and doesn't follow a logical mission progression.

Nano Banana Pro

  • + Near-perfect adherence to the 6-step mission sequence requested.
  • + High-quality text rendering with correct labels like 'Translunar' and 'Tranquility'.
  • + Accurate technical illustrations of the Saturn V, CSM, and Lunar Module.
  • The layout is slightly more crowded than Model A.
  • Uses more detailed shading than the 'flat-vector' request implied, though still within an infographic style.

Verdict: Nano Banana Pro is the clear winner as it accurately followed all six sequential steps of the Apollo 11 mission with legible, correct text labels. FLUX.1 [dev] produced a visually pleasing aesthetic but failed significantly on infographic utility by providing gibberish text and irrelevant astronomical icons like ringed planets.
