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.2 [klein] 4B
FLUX1.1 [pro]

AI Judge Analysis

FLUX.2 [klein] 4B

  • + Excellent adherence to the 'small' sphere description
  • + Highly realistic textures on the book cover and wooden table
  • + Accurate glass reflections and caustic effects on the table
  • The glass cube has some slight perspective issues on the bottom right edge

FLUX1.1 [pro]

  • + Strong composition and vibrant color palette
  • + Good rendering of the window light source
  • + Clearer visibility of the plant through the glass
  • The 'small' blue sphere appears quite large and occupies most of the cube
  • The sphere is levitating rather than sitting inside, which may look unnatural to some
  • The glass object is more of a rectangular prism than a cube

Verdict: FLUX.2 [klein] 4B is the winner because it followed the scale and shape instructions much better, correctly identifying all objects as a cube and a small sphere. FLUX1.1 [pro] produced a beautiful image, but the central object is not a cube and the sphere is large rather than small as requested.

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.2 [klein] 4B
FLUX1.1 [pro]

AI Judge Analysis

FLUX.2 [klein] 4B

  • + Excellent depiction of light rain and detailed wet pavement reflections.
  • + Realistic skin texture and age details on the man's hands and face.
  • + Naturalistic interaction with the bicycle parts.
  • The cars in the background lack the requested motion blur, appearing mostly static.
  • The bicycle chain and frame geometry have slight structural inconsistencies under the seat.

FLUX1.1 [pro]

  • + Strong composition with a deeper sense of perspective and cityscape.
  • + Good capture of the 'candid' feel with more atmospheric lighting.
  • + Excellent depth of field with realistic bokeh.
  • The bicycle is severely glitched, appearing broken or missing its rear half entirely.
  • The man's hands are fused awkwardly with the handlebars.
  • Fails to show the man actually 'repairing' the bike, as he is just holding it.

Verdict: FLUX.2 [klein] 4B is the clear winner because it maintains the structural integrity of the bicycle and shows the man actively engaged in the repair task. While FLUX1.1 [pro] has a more cinematic atmosphere, it fails significantly on technical details, producing a mangled bicycle and nonsensical hand placements.

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.2 [klein] 4B
FLUX1.1 [pro]

AI Judge Analysis

FLUX.2 [klein] 4B

  • + Excellent depiction of the ornate engraved plate armor
  • + Clear braiding with visible beads in the hair
  • + Accurate representation of the 'close portrait' framing
  • Skin texture looks slightly too clean and digital compared to the armor detail
  • The lighting feels a bit flat and stage-like

FLUX1.1 [pro]

  • + Hyper-realistic skin texture and lifelike eyes
  • + Excellent cinematic lighting and bokeh sparks effects
  • + Strong 'battle-worn' aesthetic with detailed dirt and grime
  • The 'braids with beads' are messy and harder to distinguish
  • The engraving on the armor is less distinct than in Model A

Verdict: FLUX1.1 [pro] produces a significantly more cinematic and lifelike image with superior lighting and skin texture, though it compromises slightly on the clarity of the hair braids. FLUX.2 [klein] 4B follows the armor and hair braiding instructions more literally but has a more synthetic, less atmospheric quality overall.

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.2 [klein] 4B
FLUX1.1 [pro]

AI Judge Analysis

FLUX.2 [klein] 4B

  • + Excellent grid layout with clear food photography.
  • + Bold, readable sans-serif typography that feels modern.
  • + Adheres strictly to the 'colorful food photos in grid' part of the prompt.
  • Nonsense text and misspellings in the headings.
  • Multiple duplicate header names like 'MDANS'.

FLUX1.1 [pro]

  • + Elegant presentation with cutlery adds to the casual dining feel.
  • + More realistic hierarchy with section headers like 'APPETIZERS'.
  • + Better text rendering on the right-hand panel.
  • The food grid is small and tucked at the bottom rather than being a core focus.
  • Some text formatting is messy with overlapping lines.

Verdict: FLUX.2 [klein] 4B followed the specific structural instructions much better by creating a complete menu page with a prominent image grid and bold headers. While FLUX1.1 [pro] produced a more professional mock-up visualization, it failed to prioritize the grid of food photos as requested and relegated them to a small section at the bottom.

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.2 [klein] 4B
FLUX1.1 [pro]

AI Judge Analysis

FLUX.2 [klein] 4B

  • + Excellent photorealistic texture on the burger bun and patties
  • + Accurately represents the starburst element for the price point
  • + Good execution of the glowing ember and fiery background effect
  • Serious spelling errors in the main title
  • The burger is assembled rather than 'exploded' with suspended components

FLUX1.1 [pro]

  • + Perfect text rendering for both the title and limited time message
  • + Better captures the 'exploded' aspect with suspended ingredient fragments
  • + Maintains a clean, professional advertising layout
  • Failed to include the price in a starburst as requested
  • The burger itself is mostly assembled rather than having the main layers suspended
  • Included redundant title text

Verdict: FLUX1.1 [pro] significantly outperforms FLUX.2 [klein] 4B in text accuracy, delivering perfectly spelled titles whereas FLUX.2 [klein] 4B produces garbled text. While both models struggled to fully deconstruct the main burger layers into mid-air as requested, FLUX1.1 [pro] followed the artistic direction of suspended particles more effectively.

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.2 [klein] 4B
FLUX1.1 [pro]

AI Judge Analysis

FLUX.2 [klein] 4B

  • + The handwriting style is very realistic with convincing chalk textures and smudges on the board.
  • + It maintains a consistent slant and authentic variation in letter size as requested.
  • + The overall composition feels like a genuine, hand-crafted cafe board.
  • Contains several spelling errors such as 'Musheram', 'Ootrpous', and 'Buter'.
  • The title contains a stuttering error with 'TODAY'S S TPECIALS'.

FLUX1.1 [pro]

  • + Excellent atmospheric lighting and background context of a cozy cafe.
  • + The handwriting is legible and aesthetically pleasing.
  • + Includes decorative flourishes that add to the elegant cursive requirement.
  • Failed the price prompt significantly, listing one item as $228 instead of $28.
  • Hallucinated extra lines of text and weirdly split the octopus dish into two separate entries.
  • Spelling errors present like 'Herbss' and 'Chipkies'.

Verdict: While both models struggled with perfect spelling, FLUX.2 [klein] 4B followed the specific menu list and pricing much more accurately than FLUX1.1 [pro], which hallucinated extra items and incorrect prices. FLUX.2 [klein] 4B also captured a more convincing 'chalk on board' texture compared to the cleaner, somewhat digital look of the text in FLUX1.1 [pro].

The Reversed Rodeo

Text-to-Image

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

FLUX.2 [klein] 4B
FLUX1.1 [pro]

AI Judge Analysis

FLUX.2 [klein] 4B

  • + Excellent anatomical clarity of both the horse and the astronaut.
  • + High cinematic quality with realistic lighting from the planet below.
  • + Clean rendering of the space suit and facial features through the visor.
  • The astronaut is on top, failing the specific 'horse on top' negative constraint.
  • The composition is a bit literal and less 'surreal' than requested.

FLUX1.1 [pro]

  • + Dynamic and surreal composition with a painterly, artistic style.
  • + Interesting use of color in the mane and tail to match the nebula.
  • + More creative interpretation of the environment.
  • Failed the prompt constraint 'horse on top, not vice versa' just as Image A did.
  • The horse's torso has some strange anatomical distortions/merged textures with the suit.
  • The background clouds look more terrestrial than space-like.

Verdict: Both models failed the negative constraint to put the horse on top of the astronaut, instead providing the standard astronaut-on-horse configuration. FLUX.2 [klein] 4B is the winner due to significantly higher technical execution, clearer details, and a more believable cinematic lighting setup, whereas FLUX1.1 [pro] has anatomical inconsistencies on the horse's body.

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.2 [klein] 4B
FLUX1.1 [pro]

AI Judge Analysis

FLUX.2 [klein] 4B

  • + Perfect adherence to the 'both paws on the steering wheel' instruction.
  • + Excellent taxi interior realism with a clear view of the dashboard and steering wheel.
  • + The businesswoman's bored expression and posture are very natural.

FLUX1.1 [pro]

  • + High cinematic quality with beautiful bokeh and lighting effects.
  • + Clear text rendering of 'TAXI' on the cap.
  • + High level of fur detail on the capybara.
  • Failed the steering wheel instruction; the capybara appears to be holding the phone or just gesturing.
  • The layout is cramped, making the interior look less like a real vehicle.

Verdict: FLUX.2 [klein] 4B followed the technical details of the prompt much better, specifically regarding the paws on the steering wheel and the spatial layout of a taxi. FLUX1.1 [pro] produced a more aesthetically pleasing image with better lighting, but failed on the key interaction of the driver with the vehicle.

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.2 [klein] 4B
FLUX1.1 [pro]

AI Judge Analysis

FLUX.2 [klein] 4B

  • + Excellent composition with a strong central focus and high-quality moody lighting.
  • + Captures the parchment aesthetic perfectly with a detailed thorn and web border.
  • + Followed the spacing and layout of a vintage poster effectively.
  • Major spelling errors in the main title text.
  • Incorrect date '30.10.206' and some garbled characters in the footer.

FLUX1.1 [pro]

  • + High visual clarity and striking color contrast.
  • + Accurately rendered more of the required event details without missing digits in the date.
  • + Good use of vertical space for the requested elements.
  • Repetitive text rendering, including redundant lines for time and location.
  • Missed the square format request, producing a vertical poster instead.
  • Layout feels cluttered at the bottom with overlapping or repeating headers.

Verdict: Both models struggled with text accuracy, but FLUX1.1 [pro] managed to correctly render the specific date and address, whereas FLUX.2 [klein] 4B failed significantly on the title spelling and numeric date. However, FLUX.2 [klein] 4B followed the square format instruction and provided a much more cohesive 'vintage parchment' aesthetic compared to the modern, high-contrast look of FLUX1.1 [pro]. FLUX1.1 [pro] is the likely winner for its more readable and complete information, despite the layout issues.

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.2 [klein] 4B
FLUX1.1 [pro]

AI Judge Analysis

FLUX.2 [klein] 4B

  • + Excellent PBR texturing on the salmon and plate
  • + Clear and bold typography
  • + Realistic lighting and shadows
  • Typographical error ('SUSH' instead of 'SUSHI')
  • The flag icon does not represent Japan (looks more like Latvia or Austria)

FLUX1.1 [pro]

  • + Perfect text rendering for both 'JAPAN' and 'SUSHI'
  • + Captures the 'miniature 3D cartoon' aesthetic perfectly
  • + Complex and visually appealing isometric composition
  • Missing the requested flag icon
  • Contains extraneous garnish (tomatoes) that aren't typically associated with sushi

Verdict: FLUX1.1 [pro] better captured the requested '3D cartoon' style and isometric diorama feel, while providing perfect text rendering. Although FLUX.2 [klein] 4B had more realistic textures (PBR), it failed the spelling of 'SUSHI' and generated an incorrect flag, making FLUX1.1 [pro] the more successful interpretation of the prompt.

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.2 [klein] 4B
FLUX1.1 [pro]

AI Judge Analysis

FLUX.2 [klein] 4B

  • + Successfully included the red fox kit which was missing in the other image
  • + Depicts dynamic action with animals tumbling and chasing butterflies
  • + Maintains clear distinction between different animal species
  • Missed the baby bunny in the group
  • Includes two kittens instead of the one requested
  • Lighting on the butterflies feels slightly overlaid rather than integrated

FLUX1.1 [pro]

  • + Stronger emotional resonance with big expressive eyes looking upward
  • + Masterful use of backlighting and rim lighting to create a soft, glowing atmosphere
  • + Beautifully rendered butterflies that feel part of the scene's light
  • Failed significantly on inclusion criteria, missing both the fox and the bunny
  • The 'bunny' features are anatomically confused with the kitten's face
  • Static composition rather than the requested 'tumbling' and 'chasing'

Verdict: FLUX.2 [klein] 4B followed the complex prompt more closely by including the fox and depicting animals in motion, although it missed the bunny. FLUX1.1 [pro] produced a more aesthetically pleasing image with superior lighting, but failed to include half of the requested animals and the requested action. FLUX.2 [klein] 4B is the better choice for its adherence to the multi-animal interaction.

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.2 [klein] 4B
FLUX1.1 [pro]

AI Judge Analysis

FLUX.2 [klein] 4B

  • + Clean vector emblem style with a minimalist aesthetic.
  • + Features a clearly defined cloche dome and steam.
  • + Captures the requested warm brown and cream tones well.
  • Significant spelling error in the name ('FLAXTION' instead of 'Florian').
  • Redundant 'Est. 1720' text appearing twice.

FLUX1.1 [pro]

  • + High-quality vintage illustration style with intricate detailing.
  • + Sophisticated use of classic typography and framing.
  • + Excellent execution of the 'Est. 1720' banner.
  • Spelling error in the brand name ('Cafeé Fratilian').
  • Slightly more complex than a 'minimalist' logo request.

Verdict: Both models failed to correctly spell 'Caffè Florian', but FLUX1.1 [pro] produced a more visually cohesive and professionally designed logo with superior classic typography. FLUX.2 [klein] 4B followed the minimalism requirement more closely but suffered from redundant text and a larger spelling hallucination.

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.2 [klein] 4B
FLUX1.1 [pro]

AI Judge Analysis

FLUX.2 [klein] 4B

  • + Successfully uses the requested NASA-inspired palette including the muted red and navy blue.
  • + Icons for Earth, Moon, and the Lunar Module are clear and recognizable.
  • + Includes mentions of the crew (Aldrin, Collins) as requested by the 'supporting...' prompt segment.
  • Text rendering is poor with significant misspellings throughout the image.
  • The layout lacks a clear sequential flow for an infographic.
  • The Saturn V icon is distorted and anatomically incorrect for the rocket.

FLUX1.1 [pro]

  • + Excellent typography with a clear and correctly spelled 'APOLLO 11' header.
  • + Strong modern vector aesthetic with a clean, professional layout and consistent iconography.
  • + Captures the infographic style perfectly with numbered steps and a cohesive visual theme.
  • Smaller body text is illegible and contains gibberish characters.
  • Does not explicitly show a Saturn V rocket icon, opting for a generic rocket shape.

Verdict: FLUX1.1 [pro] significantly outperforms FLUX.2 [klein] 4B by delivering a professional-grade infographic layout that feels modern and intentional. While FLUX.2 attempts more of the specific text content, its poor spelling and disjointed composition make it less effective than the clean, structured, and visually appealing design of FLUX1.1.
