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]
- + Exceptional clarity and refraction in the glass cube.
- + High level of detail in the wooden table texture.
- + Vibrant colors and sharp focus on the central objects.
- − Included an extra blue sphere on top of the book not requested in the prompt.
- − The sphere inside appears to be floating unnaturally without support or resting on the bottom.
FLUX.2 [pro]
- + Perfect adherence to all prompt elements with no extra objects.
- + Realistic physics with the sphere resting on the bottom of the cube.
- + Excellent handling of depth of field and soft lighting.
- − The plant in the background is quite blurry, making it harder to see through the glass as requested.
- − The cube edges are very thin compared to the solid look of Model A.
Verdict: FLUX.2 [pro] followed the prompt instructions perfectly, whereas FLUX.1 [schnell] hallucinated an additional blue sphere on top of the book. While FLUX.1 [schnell] produced a more striking image with beautiful glass refractions, FLUX.2 [pro] is the superior choice for prompt accuracy and realistic composition.
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]
- + Excellent color saturation on the red bicycle
- + Good composition with the sujeto filling the frame
- − The cars in the background are at a complete standstill rather than showing motion blur
- − The hands look a bit fused/muddled around the handlebars
- − The bicycle geometry is slightly unnatural around the cranks
FLUX.2 [pro]
- + Successfully captures the requested motion blur on the passing vehicle
- + Includes visible rain droplets and realistic ripples in the puddle reflections
- + Hands are clearly engaged in a mechanical task (repairing the chain)
- − The framing is slightly more conventional than the 'imperfect' request implied
- − The bicycle is missing its handlebars or they are strangely cropped/oriented
Verdict: Both models followed the prompt well, but FLUX.2 [pro] followed the technical details more closely by including the requested motion blur and rain details. While FLUX.1 [schnell] has a vibrant aesthetic, FLUX.2 [pro] feels much more like an actual candid street photograph with realistic textures and atmosphere.
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]
- + Excellent intensity in the eyes and facial expression
- + Intricate engraving on the dark plate armor
- + Clean, high-resolution textures on the skin
- − Failed to include the beads in the braids
- − Lighting feels a bit flat compared to the environmental prompt
- − Lacks the bokeh sparks requested
FLUX.2 [pro]
- + Perfect adherence to all prompt details including beads and bokeh sparks
- + Superior lighting realism with warm torchlight reflection
- + Highly detailed texture on the leather straps and burlap-like hood/underlayer
- − The scars look a bit like surface paint rather than deep tissue injuries
- − Composition is slightly less focused on the face than Model A
Verdict: FLUX.2 [pro] followed the prompt much more accurately, including specific elements like the beads and bokeh sparks that FLUX.1 [schnell] missed. While FLUX.1 [schnell] has a very striking facial portrait, the lighting and material variety in FLUX.2 [pro] create a more immersive and realistic scene.
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]
- + Clean minimalist layout with high-quality white space.
- + Accurate sans-serif typography that feels professional and spacious.
- − Included gibberish text 'ORFEFUS' as a section header.
- − Food photos lack diversity, showing three similar-looking pizzas/flatbreads instead of distinct categories.
FLUX.2 [pro]
- + Excellent use of vibrant colorful accents to differentiate sections.
- + Strong grid layout for photos with legible item names and prices.
- + Better variety in food photography reflecting the requested categories.
- − Spelling error in the 'MAINS' section which is labeled as 'MINS'.
- − Redundant labeling with 'Pizza' appearing multiple times in different sections.
Verdict: FLUX.2 [pro] followed the prompt more effectively by incorporating vibrant color accents and a clear grid for food photos that actually correspond to different menu items. While FLUX.1 [schnell] achieved a cleaner 'minimalist' aesthetic, its food images were repetitive and one of its main headers was a nonsense word.
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]
- + The burger patty and lettuce have high-resolution, photorealistic textures.
- + The fiery background with glowing embers is visually dynamic and fits the prompt well.
- − The text is highly inaccurate, missing the first letter 'M' and repeating the price incorrectly.
- − The burger is mostly assembled rather than 'exploded' as requested.
- − The floating objects around the burger look like generic croutons or nuggets rather than burger components.
FLUX.2 [pro]
- + Perfect text rendering for all requested strings with the specified fiery, glowing effect.
- + Exploded composition accurately depicts the individual layers suspended in mid-air.
- + Excellent integration of the starburst element and price as requested.
- − The 'exploded' layers are a bit repetitive with two patties when the prompt implied a single set of components.
- − The sauce trails are slightly stylized compared to a purely photorealistic look.
Verdict: FLUX.2 [pro] is the clear winner as it followed every instruction, including the complex text and layout requirements, perfectly. FLUX.1 [schnell] failed significantly on text accuracy and did not achieve the specific 'exploded' layout requested in the prompt.
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]
- + The text is legible and generally well-aligned.
- + It captures the requested 'Brown Butter' item partially.
- − Numerous spelling errors in almost every line (e.g., 'Pril', 'Taffle', 'Mushmnctiomn').
- − The handwriting looks more like a digital marker font than authentic chalk.
- − The formatting is messy with repeated lines and price symbols.
FLUX.2 [pro]
- + Perfect text rendering with zero spelling errors and correct punctuation.
- + Extremely realistic chalk texture including dust, smudges, and authentic cursive strokes.
- + Excellent composition with a natural cafe atmosphere in the background.
- − The date is slightly smaller than the title, though still very readable.
Verdict: FLUX.2 [pro] is the clear winner as it followed every instruction perfectly, including complex spelling and the specific chalk texture requested. While FLUX.1 [schnell] struggled with spelling and produced a marker-like appearance, FLUX.2 [pro] delivered a professional, high-quality image that looks like a real handwritten chalkboard.
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]
- + Excellent adherence to the 'horse on top' spatial instruction
- + Cinematic lighting and composition with the planetary rim
- + Coherent single horse figure
- − Anatomical glitch where a second horse head emerges from the main horse's neck
- − The astronaut's suit geometry is a bit surreal and chaotic
FLUX.2 [pro]
- + High resolution and crisp textures on the astronaut suit
- + Vibrant, detailed space background with multiple galaxies
- + Great lighting on the horse's mane
- − Fails the prompt's spatial requirement as the horse appears behind or under the astronaut rather than riding him
- − Major anatomical failure with a two-bodied horse/centaur-like entity
Verdict: FLUX.1 [schnell] followed the difficult spatial instruction of having the horse on top, creating a clear 'riding' silhouette, despite a minor anatomical error on the horse's head. FLUX.2 [pro] failed to place the horse on top and produced a highly distorted creature with two bodies and five legs. FLUX.1 [schnell] is much closer to the requested surreal concept.
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]
- + Excellent character expressions, perfectly capturing the bored businesswoman and professional capybara.
- + Clear, high-quality rendering of fur and lighting.
- + Good text rendering on the hat and visor.
- − The capybara's anatomy is a bit awkward with one paw far from the wheel.
- − The taxi interior is a bit generic and dark compared to Model B.
FLUX.2 [pro]
- + Highly realistic taxi interior with intricate dashboard and exterior lighting details.
- + Superior composition showing the full perspective of the car interior.
- + Accurately places both paws on the steering wheel as requested.
- − The capybara's hands look slightly more like human hands in gloves than actual paws.
- − The passenger in the back is less focused and her expression is harder to read.
Verdict: While FLUX.1 [schnell] captures the specific facial expressions and 'vibe' of the prompt more effectively, FLUX.2 [pro] produces a much more technically impressive and realistic car interior. FLUX.2 [pro] followed the mechanical instructions better (both paws on wheel) and the lighting/textures of the Manhattan night are significantly more immersive.
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]
- + Excellent typography style for the main title
- + Good use of vertical space and graphic elements
- − Major text errors including 'You invited to a a night of frights'
- − Repeats date and time fields with nonsense words like 'butistigtion'
- − Art style feels more like a 2D illustration than a cinematic poster
FLUX.2 [pro]
- + Perfect text rendering for all requested fields with no spelling errors
- + Superior cinematic lighting and realistic textures on the pumpkin and parchment
- + Effectively incorporates all requested elements like the scroll banner and thorns in an elegant way
- − The 'Date' text is slightly off-center compared to the title
Verdict: FLUX.2 [pro] is the clear winner as it successfully rendered every line of text perfectly, whereas FLUX.1 [schnell] suffered from significant spelling errors and repetitive lines. Model B also better captured the 'cinematic' and 'parchment' aesthetic, providing a professional-looking invitation compared to the flatter, illustrative style of Model A.
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]
- + Excellent high-clarity PBR materials on the fish texture
- + Clean and minimalist composition
- + Perfectly centered and ultra-clean aesthetic
- − Failed to include the word 'SUSHI' in text
- − The flag icon is slightly generic compared to the requested style
FLUX.2 [pro]
- + Followed all text instructions including 'JAPAN' and 'SUSHI'
- + Accurate interpretation of the 'cartoon scene' style with soft textures
- + Superior diorama base design with secondary garnishes like wasabi and ginger
- − Text is somewhat oversized and crowded at the top
- − Lighting is a bit flatter than the PBR request suggested
Verdict: While FLUX.1 [schnell] produced a more visually stunning and realistic sushi material, it failed to include half of the requested text. FLUX.2 [pro] followed the prompt's instructions perfectly, including all text and a more comprehensive 3D miniature scene.
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]
- + Vibrant, saturated colors that create a joyful atmosphere
- + High level of detail in the fur texture
- + Effective use of warm, golden hour lighting
- − Failed to include a rabbit, instead showing a creature with cat and rabbit features
- − The anatomy of the middle-right animal is ambiguous and incoherent
FLUX.2 [pro]
- + Successfully included all four distinct animals requested: puppy, kitten, bunny, and fox
- + More realistic interactions and placement of the animals
- + Achieves the 'dew sparkles' and subtle 'god rays' more effectively
- − The kitten's pose is slightly physically awkward
- − Some butterflies appear to be clipping or floating strangely on the animals' faces
Verdict: FLUX.2 [pro] is the clear winner because it correctly adhered to the complex prompt's list of animals, whereas FLUX.1 [schnell] missed the rabbit and generated a confusing hybrid creature instead. FLUX.2 [pro] also managed the lighting and background details with more subtlety and realism.
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]
- + Strong minimalist vector aesthetic
- + Clean balanced layout
- + Precise line weights for an icon-style logo
- − Incorrect text spelling for both the name and the date
- − Missing requested steam element
- − Date says 7720 instead of 1720
FLUX.2 [pro]
- + Perfect text accuracy for name and date
- + Includes all prompt elements including steam and banner
- + Elegant use of shading and texture on the background
- − Slightly less 'minimalist' than a standard vector emblem due to complex shading
Verdict: FLUX.2 [pro] is the clear winner as it followed every instruction, including the specific name 'Caffè Florian' and the correct date '1720', while also including the steam and banner elements. FLUX.1 [schnell] failed significantly on text rendering, misspelling the name as 'Cafeé Framilan' and hallucinating the year as '7720'.
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]
- + Successfully uses the requested NASA-inspired color palette
- + Clean vector aesthetic with consistent iconography
- − Failed to provide a clear step-by-step sequence
- − Central graphic is abstract and doesn't clearly show the trajectory
- − Text is largely illegible gibberish
FLUX.2 [pro]
- + Excellent adherence to the sequential 6-step structure and iconography
- + Legible main headings for every stage of the mission
- + Higher quality icons including the lunar module and astronaut names
- − The placeholder body text under headings is nonsensical
- − Subtle gradient use is slightly more pronounced than 'subtle'
Verdict: FLUX.2 [pro] significantly outperformed FLUX.1 [schnell] by correctly organizing the infographic into a logical, sequential layout that follows the requested six steps. While FLUX.1 [schnell] captured the minimalist vector style well, it failed to provide a readable or educational infographic structure compared to the clear headings and accurate iconography provided by FLUX.2 [pro].
