AI Judge Analysis

FLUX.2 [dev] Flash

  • + Perfect adherence to the spatial requirements of the prompt.
  • + Highly realistic glass textures, including thickness and slight imperfections.
  • + Balanced composition with accurate window lighting from the left.
  • The plant is slightly more to the side than directly 'behind' the cube, though still visible through it.

Stable Diffusion 3.5 Large

  • + Clean, sharp aesthetic with vibrant colors.
  • + Good rendering of the blue sphere with realistic shadows.
  • Failed the spatial prompt: the book is inside/under the cube rather than on top.
  • The glass cube lacks a bottom face, appearing more like a cover or a five-sided box.
  • The background plant is barely visible through the cube compared to the reflections.

Verdict: FLUX.2 [dev] Flash followed the complex spatial instructions perfectly, placing the sphere inside and the book correctly on top of the cube. In contrast, Stable Diffusion 3.5 Large struggled with the arrangement, placing the book at the base and omitting the bottom of the glass cube. FLUX.2 also provided a much more photorealistic result with convincing glass caustic and refraction.

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.2 [dev] Flash

  • + Excellent realism in skin texture and facial features of the elderly man.
  • + Highly detailed and accurate representation of the bicycle components.
  • + Perfectly executed motion blur on the background cars as requested.
  • The 50mm lens depth of field effect is slightly subtle in the immediate background.
  • The rain effect is very light, almost difficult to see.

Stable Diffusion 3.5 Large

  • + Strong atmospheric lighting and cinematic mood.
  • + Clearer visibility of falling rain and splashes on the ground.
  • + Good use of shallow depth of field to separate the subject from the background.
  • The bicycle's anatomy is nonsensical (no chain, no seat, disconnected frames).
  • The hands and skin texture look overly smooth and less realistic than requested.
  • The background car is sharp/static rather than having the requested motion blur.

Verdict: FLUX.2 [dev] Flash is the clear winner due to its superior anatomical accuracy and adherence to technical prompt details like motion blur and natural skin texture. While Stable Diffusion 3.5 Large creates a moodier atmosphere, its failure to generate a functional bicycle (missing seat and chain) and the lack of motion blur on the car makes it less successful as a realistic street photo.

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.”

100% wins 0% ties 0% wins

AI Judge Analysis

FLUX.2 [dev] Flash

  • + Excellent adherence to the 'beads' requirement in the braids.
  • + Very detailed texture on leather straps and cloth underlayer as requested.
  • + Superior lighting with clear torchlight reflections and orange glow on the metal.
  • The scars look a bit more like superficial fresh surface cuts rather than healed battle scars.

Stable Diffusion 3.5 Large

  • + Intricate engraving on the plate armor with high contrast.
  • + Good implementation of shallow depth of field with the background army.
  • + Dynamic facial expression and intense lifelike eyes.
  • Completely missed the 'small beads' in the hair braids.
  • Leather straps mentioned in the prompt are not featured in the composition.
  • Lighting feels a bit more like natural daylight than warm torchlight.

Verdict: FLUX.2 [dev] Flash adhered much better to the specific details of the prompt, successfully including the beads in the hair and the leather straps which Stable Diffusion 3.5 Large omitted. While Stable Diffusion 3.5 Large produced beautiful armor engravings, FLUX.2 captured the atmospheric warm torchlight and material textures more accurately.

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 [dev] Flash
Stable Diffusion 3.5 Large

AI Judge Analysis

FLUX.2 [dev] Flash

  • + Excellent adherence to the 'grid' layouts for food photos.
  • + Strong typography for section headers (Appetizers, Pizza, Mains).
  • + Effective use of vibrant color accents in the UI elements.
  • Text spelling is inconsistent (e.g., 'Cassual', 'A!ZLA').
  • Visual clutter in the header area with overlapping shapes.
  • Pricing and item descriptions are repetitive and nonsensical.

Stable Diffusion 3.5 Large

  • + Very clean and modern minimalist aesthetic.
  • + High-quality, appetizing food photography.
  • + Bold use of sans-serif fonts matches the 'modern minimalist' request.
  • Layout is more of a gallery than a functional menu grid.
  • Text content is largely illegible gibberish.
  • The vertical column layout makes the menu feel cramped compared to traditional designs.

Verdict: FLUX.2 [dev] Flash followed the 'grid' and 'sections' prompt more closely, resulting in a design that looks like an actual physical menu page. Stable Diffusion 3.5 Large produced a more aesthetically pleasing but less functional layout that feels like a website landing page rather than a printable menu. FLUX.2 is the winner for its better structural adherence and clearer compartmentalization of food items.

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 [dev] Flash
Stable Diffusion 3.5 Large

AI Judge Analysis

FLUX.2 [dev] Flash

  • + Excellent adherence to the 'exploded' and 'suspended' burger requirement.
  • + Perfect font rendering including the specific starburst and fiery effects.
  • + Clean, professional composition suitable for a real advertisement.
  • The lighting on the bottom lettuce is a bit flat compared to the top elements.

Stable Diffusion 3.5 Large

  • + Intense fiery atmosphere with realistic lighting effects on the burger buns.
  • + High level of detail on the meat textures and grill marks.
  • Completely failed to include any of the requested text.
  • Failed to create an 'exploded' view; the burger is mostly intact and stacked.
  • The composition is crowded and ignores the 'exploded' directive.

Verdict: FLUX.2 [dev] Flash perfectly executed every part of the prompt, including the complex text integration and the difficult 'exploded' burger layout. Stable Diffusion 3.5 Large produced a high-quality image of a burger on fire, but failed both the text and the layout requirements of 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.”

FLUX.2 [dev] Flash
Stable Diffusion 3.5 Large

AI Judge Analysis

FLUX.2 [dev] Flash

  • + Excellent text rendering with near-perfect spelling and legibility.
  • + The chalk texture is highly realistic with dust smudges and authentic line weights.
  • + Completed the truncated prompt creatively by adding 'Cookies' and price.
  • The 'Today's Specials' title is more of a print-block style than the requested 'elegant cursive'.

Stable Diffusion 3.5 Large

  • + Successfully captured a wider cafe environment and layout.
  • + Includes the requested 'April 30' date accurately.
  • Significant text issues including many spelling errors and illegible 'mush' text.
  • The date year is incorrect (2024 instead of 2026).
  • The 'chalkboard' style looks digitally generated with clean lines rather than natural hand-drawn chalk.

Verdict: FLUX.2 [dev] Flash follows the prompt much more effectively, particularly in its ability to render legible, correctly spelled text that truly looks like it was written with chalk. Stable Diffusion 3.5 Large struggles significantly with the text content, featuring numerous misspellings and failing to maintain the realistic chalk texture requested.

The Reversed Rodeo

Text-to-Image

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

FLUX.2 [dev] Flash
Stable Diffusion 3.5 Large

AI Judge Analysis

FLUX.2 [dev] Flash

  • + Excellent anatomical details on the horse's head and mane.
  • + Sharp rendering of the astronaut's suit and gear.
  • + Clear composition with balanced celestial bodies.
  • Failed the core prompt instruction of having the horse on top of the astronaut.

Stable Diffusion 3.5 Large

  • + Beautiful cinematic lighting and atmospheric dust effects.
  • + Highly detailed background with realistic planetary curvature.
  • + Good sense of movement and dynamic energy.
  • Failed the core prompt instruction of having the horse on top of the astronaut.
  • Minor anatomical issues with the horse's front legs.

Verdict: Both models completely failed the specific spatial logic of the prompt ('horse on top, not vice-versa'), instead providing standard images of an astronaut riding a horse. FLUX.2 [dev] Flash has cleaner details and better clarity, while Stable Diffusion 3.5 Large offers a superior cinematic atmosphere and more creative lighting.

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 [dev] Flash
Stable Diffusion 3.5 Large

AI Judge Analysis

FLUX.2 [dev] Flash

  • + Excellent adherence to the full prompt including the passenger.
  • + Highly photorealistic lighting and textures for both the capybara and the human.
  • + Correct spatial arrangement of the taxi interior viewing from the front windshield.
  • The capybara's paws look slightly more like claws than natural capybara feet.

Stable Diffusion 3.5 Large

  • + Sharp focus on the capybara character.
  • + Good clothing detail on the animal.
  • Completely failed to include the human passenger requested in the prompt.
  • The subject looks more like a squirrel or large rodent hybrid than a distinct capybara.
  • The composition is a side-profile that misses the 'inside the taxi' atmosphere requested.

Verdict: FLUX.2 [dev] Flash followed the instructions perfectly, including the human passenger with the correct expression and the specific taxi-driver aesthetic. Stable Diffusion 3.5 Large failed to include the passenger and produced an image that looked more like an AI-stylized rodent than a photorealistic capybara.

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 [dev] Flash
Stable Diffusion 3.5 Large

AI Judge Analysis

FLUX.2 [dev] Flash

  • + Excellent text rendering with clean, gothic typography
  • + Perfect adherence to all specific event details (Date, Time, Location)
  • + High visual quality with a cohesive illustration style
  • Includes a small line of garbled text/symbols next to the time field

Stable Diffusion 3.5 Large

  • + Strong 'parchment' aesthetic with realistic torn edges
  • + Good interpretation of the 'gothic title' and 'scroll banner' elements
  • Failed to include the specific event details (Date, Time, Location) at the bottom
  • Text alignment and font choice feel a bit modern compared to the gothic theme
  • The central pumpkin is dwarfed by the moon, straying from the 'central jack-o-lantern' instruction

Verdict: FLUX.2 [dev] Flash followed the prompt instructions much more closely, successfully including all the required event details and maintaining a consistent gothic aesthetic. Stable Diffusion 3.5 Large captured the parchment texture well but failed to render the specific date, time, and location information requested.

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.

AI Judge Analysis

FLUX.2 [dev] Flash

  • + Perfect adherence to text placement and formatting instructions.
  • + Exquisite texture work, especially on the wood grain and rice grains.
  • + Completely clean, minimalist composition that looks professional and high-clarity.
  • The sushi roll cross-section looks slightly more like a 2D graphic than a 3D model compared to the nigiri.

Stable Diffusion 3.5 Large

  • + Highly creative and detailed 'miniature' world aesthetic.
  • + Beautiful stylized 3D shapes for the sushi and garnishes.
  • + Effective use of lighting to create volume and depth.
  • Failed to place text at the top-center of the image; instead, it integrated it into flags.
  • Included too much 'garnish' and extra elements, ignoring the 'minimal' instruction.
  • The flag icon is stylized but the text placement makes the overall design feel cluttered.

Verdict: FLUX.2 [dev] Flash perfectly followed the layout instructions, placing the text exactly where requested with a clean, professional finish and excellent textures. Stable Diffusion 3.5 Large created a more vibrant and detailed 3D scene, but it ignored several negative constraints (minimal garnish) and structural requirements (text at top-center).

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.2 [dev] Flash

  • + Excellent fur textures and sharp details on all animals
  • + Includes all requested animals plus an extra bunny, fitting the 'tumbling together' prompt well
  • + Beautifully rendered lighting with clear god rays and dew sparkles
  • The fox kit has a slightly cartoonish expression compared to the other animals
  • The kitten has an extra-long, slightly awkwardly placed paw

Stable Diffusion 3.5 Large

  • + Dynamic 'chasing' composition that captures the movement requested in the prompt
  • + Captures a very joyful, infectious expression on the golden retriever puppy
  • + Soft, dreamy bokeh effect that enhances the 'wholesome' vibe
  • Anatomy issues on the fox's face which appears slightly distorted
  • The kitten's ears are more like a fox or caracal than a standard tabby kitten
  • Fur texture is slightly blurred compared to the sharpness of Model A

Verdict: FLUX.2 [dev] Flash delivered a more technically proficient image with superior fur detail, lighting effects, and better adherence to the specific species requested (the tabby kitten actually looks like a tabby). Stable Diffusion 3.5 Large captured the 'chasing' action and joyful mood better, but suffered from anatomical inconsistencies and less refined textures.

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 [dev] Flash
Stable Diffusion 3.5 Large

AI Judge Analysis

FLUX.2 [dev] Flash

  • + Excellent typography with correct spelling and accent placement.
  • + High-quality vector aesthetic with appropriate vintage texture.
  • + Strong composition that balances the banner and the cloche icon.
  • The 'Est. 1720' text is outside of the banner rather than inside it.

Stable Diffusion 3.5 Large

  • + Elegant background texture and corner flourishes.
  • + Captures the brown and cream color scheme well.
  • Incorrect spelling of the brand name as 'Cafféé'.
  • The cloche dome illustration is fragmented and lacks structural coherence.
  • Cluttered layout with many disconnected visual elements.

Verdict: FLUX.2 [dev] Flash produced a much more professional and coherent logo with perfect spelling and a polished vintage aesthetic. Stable Diffusion 3.5 Large struggled with the text ('Cafféé') and the illustration of the cloche, which appears broken and poorly proportioned.
