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
FLUX.1 [schnell] FP8
- + Excellent clean aesthetic with high-quality refractive glass effects.
- + Perfectly follows the spatial instruction of placing the plant 'behind the cube'.
- + Light from the left is naturally integrated into the scene.
- − The glass object is more of a tall rectangular prism than a 'cube'.
- − The sphere appears to be floating on an internal shelf rather than the bottom of the cube.
Wan 2.5 (Preview)
- + Accurately depicts a cubic shape for the glass container.
- + Highly realistic textures on the vintage red book and wooden table.
- + Features beautiful particulate detail in the air near the light source.
- − The plant is more 'beside' than 'behind' the cube, failing the refraction instruction.
- − The reflection of the sphere on the bottom of the cube looks slightly disconnected.
Verdict: FLUX.1 [schnell] FP8 wins on composition and adherence to the refractive element of the prompt, as the plant is clearly visible through the glass as requested. While Wan 2.5 (Preview) has superior texture realism and correctly identifies the cube shape, it fails to place the plant behind the glass cube properly.
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
FLUX.1 [schnell] FP8
- + Excellent handling of wet pavement reflections and vehicle lights
- + Captures an organic, candid posture
- + High visual quality in the background elements and bokeh
- − The man appears more Caucasian/Hispanic than specifically Japanese
- − The man is standing and holding the bike rather than actively 'repairing' it
- − Missing visible rain streaks despite the wet ground
Wan 2.5 (Preview)
- + Stronger adherence to the 'repairing' action with tools on the ground
- + Clear and realistic depiction of light rain falling
- + Authentic rendering of an elderly Japanese man's features
- − The bicycle geometry is slightly warped, especially in the wheels and frame near the seat
- − Shadows and lighting on the man's lower half feel a bit disconnected from the background
- − The hand/finger details near the chain are a bit muddy
Verdict: Wan 2.5 (Preview) more accurately followed the subject's ethnicity and specific activity of 'repairing' the bicycle with tools, whereas FLUX.1 [schnell] FP8 produced a more aesthetically pleasing street scene but failed to capture the repair action and the specific rain effect. Ultimately, Wan 2.5 is the winner for its superior prompt adherence and realistic depiction of the environmental conditions.
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
FLUX.1 [schnell] FP8
- + Intense and lifelike eye detail
- + Dramatic warm lighting that accentuates facial features
- + High texture quality on the skin and beard
- − Missed the request for 'braided hair with small beads' almost entirely
- − Overly smooth, digital look on some leather parts
Wan 2.5 (Preview)
- + Excellent adherence to specific details like braided hair with beads
- + Superior texture on raw cloth, leather straps, and engraved armor
- + Great depiction of 'battle-worn' with visible dirt and faint scars
- − The character looks somewhat young for a 'battle-worn paladin'
- − Background sparks/bokeh are a bit large and distracting
Verdict: Wan 2.5 (Preview) adhered much better to the specific prompts, including the braids with beads and the detailed cloth underlayers that FLUX.1 [schnell] FP8 missed. While FLUX.1 has a more intense cinematic portrait feel with higher skin pore detail, Wan 2.5 delivers a more complete interpretation of the armor and character description.
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
FLUX.1 [schnell] FP8
- + Crisp and clean minimalist aesthetic
- + Good attempt at multiple menu sections
- + Clean price formatting and dotted lines
- − Text is largely nonsensical and illegible
- − Inconsistent section labeling with 'Orceters' and 'Seccer'
- − Food images lack the vibrancy requested
Wan 2.5 (Preview)
- + Excellent food photography with vibrant colors
- + Very strong adherence to the 'grid' prompt
- + Clearer, bolder typography for headings
- − Multiple spelling errors in headings including 'Menue' and 'Mainns'
- − Section content doesn't always match the headers (mains are under appetizers and pizza)
Verdict: Wan 2.5 (Preview) produced a more visually striking and vibrant layout that perfectly captures the 'casual dining' vibe with high-quality imagery and a clear grid. While FLUX.1 [schnell] FP8 followed the minimalist instruction well, its text is less legible and the food photography is flatter and less appetizing by comparison.
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
FLUX.1 [schnell] FP8
- + Features a sharp, high-quality rendered burger
- + Captures the fiery background effect well with realistic flames at the bottom
- − Serious text errors including 'LIIMITED' and 'NEEY'
- − Failed to create an 'exploded' view; the burger is mostly assembled
- − Incorrect price rendering and starburst style does not match the prompt's fiery requirement
Wan 2.5 (Preview)
- + Excellent adherence to the 'exploded' burger request with deconstructed layers
- + Perfect text rendering for all requested strings
- + Strong creative interpretation of the 'fiery, glowing effect' on the typography and starburst
- − The 'cheese' layer looks slightly plastic compared to the other realistic food elements
- − A bit of repetitive sauce droplet patterns
Verdict: Wan 2.5 (Preview) significantly outperformed FLUX.1 [schnell] FP8 by adhering to every specific detail of the prompt, including the 'exploded' composition and the complex text requirements. While FLUX.1 [schnell] produced a clean central image, the catastrophic spelling errors and failure to deconstruct the burger make it unsuitable for the requested ad design.
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
FLUX.1 [schnell] FP8
- + Successfully rendered the full date as requested.
- + Realistic wooden frame and chalkboard surface lighting.
- − Failed significantly on text accuracy with repeated words and nonsense phrases.
- − Handwriting style is shaky and inconsistent compared to the prompt's request for elegance.
- − Incorrect prices for the items.
Wan 2.5 (Preview)
- + Excellent text legibility and accuracy for almost all requested items.
- + Superior chalkboard texture with realistic smudges and chalk dust.
- + Consistent, elegant cursive handwriting style that fits the 'cozy café' aesthetic.
- − Missing the 'Herbs' portion of the second menu item.
- − The text style looks slightly more like a digital brush than physical chalk in some strokes.
Verdict: Wan 2.5 (Preview) significantly outperformed FLUX.1 [schnell] FP8 by correctly rendering the complex menu names and prices with high legibility and artistic consistency. While FLUX.1 struggled with word repetition and gibberish, Wan 2.5 produced a professional, aesthetically pleasing board that followed the prompt's specific menu requirements.
The Reversed Rodeo
Text-to-Image“Horse riding astronaut in space — horse on top, not vice versa. Surreal, highly detailed, cinematic.”
AI Judge Analysis
FLUX.1 [schnell] FP8
- + Successfully followed the difficult logic of a horse riding an astronaut (the equipment)
- + Captures a surreal, cinematic lighting and atmosphere
- + Includes creative elements like the horse on top of technical gear
- − The anatomy of the horses is slightly warped and merged with the gear
- − The 'astronaut' is represented as a piece of equipment rather than a person in a suit
Wan 2.5 (Preview)
- + High visual clarity and vibrant colors
- + Technically sound horse anatomy and astronaut suit details
- − Failed the core prompt instruction of 'horse on top'
- − Produces a generic space imagery trope rather than the requested surreal scene
Verdict: FLUX.1 [schnell] FP8 is the clear winner because it successfully interpreted the challenging logic of the prompt ('horse on top, not vice versa'), whereas Wan 2.5 (Preview) completely ignored that instruction and produced a standard astronaut on a horse. While FLUX.1 has some anatomical oddities, its ability to handle complex spatial relationships makes it superior for this specific 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.”
AI Judge Analysis
FLUX.1 [schnell] FP8
- + Excellent fur texture rendering
- + Correct lighting and depth of field within the car
- + Clear legible text on the driver's cap
- − Anatomical failure with the capybara's hands/paws on the wheel
- − The passenger appears to be holding two phones which looks messy
- − Composition feels slightly cramped
Wan 2.5 (Preview)
- + Better composition showing both characters through the windshield
- + Accurate paw placement on the steering wheel
- + Very cinematic lighting and rain effects on the glass
- − The passenger's face is slightly blurry and lacks definition
- − Text on the taxi sign is nonsensical
- − The cap looks more like a police hat than a standard taxi cap
Verdict: Wan 2.5 (Preview) produced a more cohesive and realistic composition by successfully placing the capybara's paws on the wheel and staging the passenger correctly in the background. While FLUX.1 [schnell] FP8 had sharper fur and text details, it struggled with the anatomy of the hands and gave the passenger an extra phone, making Wan 2.5 the better interpretation of the prompt.
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
FLUX.1 [schnell] FP8
- + Features a moody atmosphere with dark parchment textures
- + The jack-o-lantern has a vibrant, centered glow
- − Significant spelling errors throughout all text blocks
- − Fails to include webs or thorns in the border as requested
Wan 2.5 (Preview)
- + Excellent text rendering with accurate spelling for all details
- + Follows all specific design elements including thorns, webs, and a scroll banner
- + Higher visual quality with cinematic lighting and detailed textures
- − The jack-o-lantern's fire effect is slightly messy
- − The gothic title font is a bit vibrant/red rather than purely 'dark' gothic
Verdict: Wan 2.5 (Preview) is the clear winner as it successfully rendered every specific text detail, including the date, time, and location, with perfect spelling. FLUX.1 [schnell] FP8 failed significantly on text legibility and missed multiple prompt requirements like the thorns and spider webs in the border.
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
FLUX.1 [schnell] FP8
- + Excellent 3D isometric perspective on a square diorama base
- + High-quality soft lighting and refined textures
- + Clean compositions with aesthetic color palette
- − Failed text rendering, repeating 'JAPAN' and omitting 'SUSHI'
- − The flag icon is integrated poorly into the text
Wan 2.5 (Preview)
- + Perfect adherence to text and icon requirements
- + Accurate 3D textures on the salmon and rice
- + Well-balanced composition with bold, readable typography
- − The perspective is more of a front-view than a 45-degree top-down isometric view
- − Single sushi piece is less of a 'scene' than Image A
Verdict: Wan 2.5 (Preview) followed the prompt instructions much better than FLUX.1 [schnell] FP8, particularly regarding the text and the Japan flag icon. While FLUX.1 produced the superior isometric 'diorama' aesthetic requested, its failure to render the word 'SUSHI' and its garbled text makes it less successful overall.
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
FLUX.1 [schnell] FP8
- + Warm, cinematic lighting with effective god rays
- + Extremely cute and expressive facial features
- − Failed to include a bunny, substituting it with extra cats/foxes
- − Overall aesthetic leans more toward digital illustration than hyper-photorealism
Wan 2.5 (Preview)
- + Successfully included all requested animals (puppy, kitten, bunny, and fox)
- + Excellent sense of movement with the characters jumping and running
- + Better textures for whiskers and dew sparkles
- − The fox's eyes look overly saturated and slightly unnatural
- − Background blur is a bit inconsistent in the top-right corner
Verdict: Wan 2.5 (Preview) is the clear winner as it adhered to all elements of the prompt, including the specific list of animals that FLUX.1 [schnell] FP8 partially ignored. Wan 2.5 also captured the feeling of 'chasing and tumbling' much more effectively than the static group portrait style of the FLUX model.
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
FLUX.1 [schnell] FP8
- + Clean vector-style execution
- + Good vintage color palette
- − Significant spelling errors in the brand name ('Afe Flamilan')
- − Incorrect dome interpretation, appearing more like an architectural dome than a cloche
- − Cluttered typography overlapping the ribbon
Wan 2.5 (Preview)
- + Perfect text rendering for both 'Caffè Florian' and 'Est. 1720'
- + Accurate representation of a cloche dome with steam
- + Excellent 'subtle texture' on a light, paper-like background
- − The ribbon banner design is slightly complex with its double-tier structure
Verdict: Wan 2.5 (Preview) followed the prompt instructions perfectly, correctly rendering the specific cloche dome request and providing flawless text. FLUX.1 [schnell] FP8 failed to spell the brand name correctly and misinterpreted the cloche as a building dome.
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
FLUX.1 [schnell] FP8
- + Strong typography for the main title
- + Clean minimalist layout structure
- + Accurate NASA-inspired muted color palette
- − Icons do not match the specific requested objects (e.g., Saturn V, lunar module)
- − Garbled text in the secondary headings and descriptions
- − Confusing icon flow that doesn't follow the 6-step logical sequence
Wan 2.5 (Preview)
- + Excellent iconography representing the Saturn V and Lunar Module accurately
- + Highly legible text with correct terminology for the mission phases
- + Creative and relevant inclusion of the crew members and 'Tranquility' landing site
- − Includes a space shuttle-style craft for Lunar Orbit which is historically inaccurate
- − Composition is a bit crowded compared to Model A's minimalist approach
Verdict: Wan 2.5 (Preview) produced a far more effective infographic by identifying and labeling the specific mission phases with legible text and relevant illustrations. While FLUX.1 [schnell] FP8 captured the 'clean minimalist' aesthetic better, it failed to generate recognizable icons for the mission steps and resulted in unreadable placeholder text.
