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.”
AI Judge Analysis
FLUX1.1 [pro] Ultra
- + Excellent realism with sharp textures on the book and glass edges.
- + Perfect adherence to prompt instructions including spatial relationships.
- + High-quality lighting and refraction through the glass cube.
- − The sphere is floating unnaturally in the center without support.
Nano Banana
- + Great atmospheric lighting consistent with window light.
- + Accurate placement of the green plant behind the cube.
- − The cube appears to be solid glass with a sphere inside rather than a hollow glass box, making the floating sphere look like a marble trapped in ice.
- − The book is disproportionately large or the cube is too small compared to the first model.
Verdict: FLUX1.1 [pro] Ultra produces a much more realistic and high-fidelity image with crisp details on the book's spine and the glass facets. Nano Banana captures the soft window light well, but the physical logic of the glass cube is less convincing than the sharp execution of FLUX1.1 [pro] Ultra.
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
FLUX1.1 [pro] Ultra
- + Excellent execution of long-exposure motion blur on passing vehicles.
- + High-resolution details on the subject's skin and clothing.
- + Effective use of reflections on the wet crosswalk.
- − The subject appears to be leaning on the bike rather than actively repairing it.
- − The bicycle's front wheel and frame geometry look slightly distorted/unstable.
Nano Banana
- + Stronger narrative of 'repairing' with hands actively working on the handlebars/cables.
- + Very realistic skin texture and age-appropriate details on the hands.
- + Better street-level atmosphere with raindrops visible in the air and on surfaces.
- − Failed to include the requested motion blur from passing cars.
- − The background cars are static and appear to be parked or stopped in the middle of the road.
Verdict: FLUX1.1 [pro] Ultra followed the technical camera instructions much better, specifically capturing the motion blur and the requested cinematic feel. However, Nano Banana captured a more convincing 'repair' action and higher-quality skin texture, though it ignored the motion blur requirement completely. FLUX1.1 [pro] Ultra is the winner for adhering to the complex framing and motion requests.
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
FLUX1.1 [pro] Ultra
- + Expertly captures the 'close portrait' framing for a more intimate and intense feel.
- + Highly realistic skin texture, including convincing dirt, stubble, and subtle scarring.
- + Superior lighting and color grading that feels cinematic and natural.
- − The braided hair lacks the requested 'small beads'.
- − Metal engraving is less intricate than the competitor's.
Nano Banana
- + Excellent adherence to the 'braided with small beads' detail in the hair.
- + Highly ornate and detailed engraving on the plate armor with clear eagle motifs.
- + Good use of bokeh sparks and background torches to create atmosphere.
- − The character's face has a slightly 'digital' or smoothed-over look compared to Model A.
- − The framing is a medium shot rather than the requested 'close portrait'.
- − The scars appear a bit stylized and artificial.
Verdict: FLUX1.1 [pro] Ultra produces a much more lifelike and cinematic portrait with superior skin textures and realistic lighting, though it missed the specific detail of beads in the hair. Nano Banana followed the prompt's decorative instructions more closely (beads and ornate engraving) but suffers from a more generic, CGI-like aesthetic. FLUX1.1 [pro] Ultra is the winner for its professional photographic quality and better interpretation of a 'close portrait'.
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
FLUX1.1 [pro] Ultra
- + Excellent photographic quality and realistic food textures.
- + Dynamic, modern layout with interesting geometric framing.
- + Clean professional branding and logo placement.
- − Nonsense text and significant spelling errors in headers like 'Pizzzans' and 'Appet Love'.
- − Section headers are poorly organized and cluttered.
- − Layout is a bit disjointed for a functional menu.
Nano Banana
- + Clear, readable text with mostly correct spelling like 'Appetiers' and 'Mains'.
- + Perfect adherence to the grid request with a clean 2x4 image layout.
- + Stronger use of vibrant accents and logical sectioning.
- − Image quality is slightly lower than Model A, appearing more like stock photography.
- − Slight spelling errors like 'Appetiers' and 'Remaigined'.
- − The grid spacing is a bit tight, making it look a little crowded.
Verdict: Nano Banana is the clear winner for this specific task because it creates a functional, readable menu that follows the requested grid structure perfectly. While FLUX1.1 [pro] Ultra has superior image quality, its layout is chaotic and the text is mostly gibberish, making it unusable as a menu design.
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
FLUX1.1 [pro] Ultra
- + Excellent photorealistic texture on the meat and buns
- + Strong, vibrant glowing text effects
- + Dynamic foreground and background depth with realistic fire and embers
- − Failed to include the requested starburst for the price
- − The burger structure is somewhat repetitive with three identical-looking patties
- − Includes some hallucinatory small text at the bottom borders
Nano Banana
- + Successfully followed all instructions including the starburst element
- + Superior 'exploded' dynamic composition with varied angles of the ingredients
- + Accurate rendering of the requested fiery, glowing text effects
- − The price text is slightly off-center within the starburst
- − Lower resolution/clarity in some background sparks compared to Model A
Verdict: Nano Banana is the clear winner as it fulfilled every requirement of the prompt, including the specific inclusion of a starburst for the price and a much more dynamic 'exploded' composition. FLUX1.1 [pro] Ultra produced a high-quality image but missed the starburst design element and presented a more static, stacked burger rather than one that feels truly exploded in mid-air.
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
FLUX1.1 [pro] Ultra
- + Natural chalk texture on the edges of the board.
- + Good clarity on the wood grain of the frame.
- − Numerous spelling and repetition errors like 'mushroomm ris.' and 'fresh fresh'.
- − Fails the prompt for elegant cursive handwriting.
- − Messy layout with overlapping text and repeated lines.
Nano Banana
- + Perfect text accuracy and spelling for all requested menu items.
- + Captures the cozy café atmosphere with brick walls and warm lighting.
- + Consistent, realistic chalk handwriting style as requested.
- − The angled perspective makes the far side of the text slightly harder to read.
- − Mildly generic handwriting style compared to 'elegant' cursive, though still handwritten.
Verdict: Nano Banana is the clear winner as it followed every text instruction perfectly with zero spelling errors and a beautiful, atmospheric composition. FLUX1.1 [pro] Ultra struggled significantly with the text, producing several hallucinations, repeats, and misspellings that made the menu nonsensical.
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
FLUX1.1 [pro] Ultra
- + Excellent photorealistic lighting and skin textures
- + High resolution with sharp fine details on the capybara's fur
- + Accurate rendering of the requested taxi hat and jacket
- − The capybara and woman are side-by-side instead of driver and back-seat passenger
- − The woman is holding the steering wheel despite being a 'passenger'
Nano Banana
- + Successfully positions the woman in the back seat as requested
- + Captures an atmospheric 'night film' aesthetic
- + Capybara's pose with paws on the wheel is very natural
- − Slightly lower clarity and softer details compared to the first image
- − The capybara's hat is more of a generic officer hat than a specific taxi driver cap
Verdict: While FLUX1.1 [pro] Ultra produces a much sharper, high-fidelity image with superior textures, it fails significantly on the spatial layout by placing the passenger in the front seat holding the wheel. Nano Banana correctly follows the compositional instructions, placing the woman in the back seat and the capybara in the driver's seat, making it the more successful interpretation of the prompt despite lower resolution.
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
FLUX1.1 [pro] Ultra
- + Excellent crispness and clarity in the gothic font choice.
- + Very detailed thorn and web border that feels high-quality and professional.
- + Perfectly followed the request for a 'parchment poster' look.
- − Contains significant text repetition and gibberish in the middle section ('a noickt or a night of frights').
- − Missed the word 'Party' in the main title text.
Nano Banana
- + Correctly rendered all requested text including the full title 'Halloween Party Invitation'.
- + Includes a better interpretation of the 'moody night sky' with a visible moon and clouds.
- + Zero spelling errors or duplicate text lines.
- − The border quality is a bit muddy and lacks the sharp definition seen in the other model.
- − The jack-o-lantern looks slightly more generic and less integrated into the environment.
Verdict: Nano Banana is the winner because it successfully followed every text instruction without errors, whereas FLUX1.1 [pro] Ultra included a large block of repetitive gibberish and missed a word in the header. While FLUX1.1 [pro] Ultra had superior artistic detail in the border and parchment texture, Nano Banana's adherence to the prompt and flawless spelling make it a much more usable invitation.
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
FLUX1.1 [pro] Ultra
- + Excellent soft lighting and refined PBR textures that feel high-end
- + Beautifully integrated typography and flag icon
- + Sophisticated composition with a clean, professional aesthetic
- − Includes some odd elements like a small bug on the board and steam rising from cold sushi
Nano Banana
- + Perfect adherence to specific layout requests like large bold text and flag placement
- + Clearly defined isometric miniature style
- + Realistic variety of sushi types presented on a diorama board
- − The 'JAPAN' text is slightly off-center and feels like a simple overlay
- − Textures are a bit more matte and less realistic than requested
- − Some minor clipping and model quality issues on the rice textures
Verdict: FLUX1.1 [pro] Ultra produces a much more visually stunning result with superior lighting and professional-grade rendering that looks like a high-budget 3D illustration. While Nano Banana follows the layout instructions more literally, its graphic design elements feel disconnected from the scene and its 3D models lack the polish of the FLUX 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
FLUX1.1 [pro] Ultra
- + Excellent soft lighting and glow effects
- + Consistency in eye style and color palette across all animals
- + Clean, high-quality rendering with minimal artifacts
- − The animals look much more like stylized/CGI plush toys than 'photorealistic' creatures
- − All animals have almost identical facial structures and expressions
Nano Banana
- + Better 'tumbling' interaction as requested in the prompt
- + More realistic textures for the kitten and puppy
- + Distinct species characteristics are preserved better than the other model
- − The fox's paw/leg anatomy is physically distorted and messy
- − The butterflies look like flat stickers rather than integrated 3D elements
- − Light rays feel a bit artificial and over-processed
Verdict: Nano Banana followed the specific action of the prompt ('tumbling together') more effectively and managed to make the animals look like distinct species rather than stylized clones. While FLUX1.1 [pro] Ultra has a cleaner, more professional aesthetic with superior lighting, its output leans too far into a 'Disney' CGI style, failing the photorealistic requirement.
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
FLUX1.1 [pro] Ultra
- + Strong vector emblem aesthetic with bold, clear lines.
- + Excellent use of the specified warm brown and cream color palette.
- + Good incorporation of the cloche and steam elements.
- − Failed the primary text spelling by adding extra letters ('Framilian').
- − The composition feels a bit crowded compared to the 'minimalist' request.
Nano Banana
- + Perfect text rendering for both 'Caffè Florian' and 'Est. 1720'.
- + Elegant minimalist design with a clean, airy composition.
- + Accurate interpretation of the 'vintage' and 'subtle texture' requirements.
- − The 'steam' element is represented by abstract swirls rather than a realistic steam effect.
- − Lacks the distinct banner mentioned in the prompt, opting for a ribbon-style scroll.
Verdict: Nano Banana followed the core text instructions perfectly, whereas FLUX1.1 [pro] Ultra hallucinated letters in the primary brand name ('Framilian'). While FLUX1.1 [pro] Ultra has a stronger 'emblem' feel, Nano Banana is preferred for its superior legibility and adherence to the minimalist, vintage aesthetic.
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
FLUX1.1 [pro] Ultra
- + Captures a more dynamic and artistic layout with the lunar surface curve.
- + Follows the NASA-inspired color palette effectively.
- + High overall image resolution and crispness.
- − The text is largely gibberish and incoherent.
- − The logical flow of the infographic is confusing and out of order.
- − Features multiple redundant or nonsensical icons that do not match the specific steps requested.
Nano Banana
- + Excellent adherence to the sequential steps and iconography requested.
- + Very clean, legible, and professional vector style.
- + Higher quality text rendering and logical information design.
- − Missing one of the requested steps (shows 5 steps instead of 6, skipping 'Descent').
- − The composition is a bit safe and less ambitious than the competing model.
Verdict: Nano Banana is the clear winner for its functional design and logical adherence to the icons requested in the prompt, despite missing one of the six steps. FLUX1.1 [pro] Ultra produces a visually interesting background, but its infographic content is chaotic, illegible, and fails to follow the ordered instructions.
