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
FLUX.2 [max]
AI Judge Analysis
FLUX.2 [klein] 4B
- + Excellent adherence to lighting and placement prompts.
- + The plant visibility through the glass is highly realistic with appropriate optical distortion.
- + Materials like the wood grain and leather book texture look authentic.
- − The glass cube appears more like acrylic or thin plastic due to the lack of thickness in the panes.
FLUX.2 [max]
- + Sophisticated glass rendering with realistic bevels and edge thickness.
- + High-quality textures on the red book and blue sphere.
- + Clear adherence to all spatial requirements of the prompt.
- − The plant is slightly more blurred/defocused in the background compared to the other image.
- − The sphere has some slight internal reflections that look a bit like digital artifacts.
Verdict: Both models followed the prompt perfectly, placing all elements in the correct positions with the requested lighting. FLUX.2 [max] is slightly preferred for its superior rendering of the glass cube's physical thickness and edges, whereas FLUX.2 [klein] 4B feels slightly more like a real photograph but with thinner material quality.
Man and Car in California
EditingEdit instruction
“Make a photo of the man driving the car down the California coastline”
Source
FLUX.2 [klein] 4B
FLUX.2 [max]
AI Judge Analysis
FLUX.2 [klein] 4B
- + Excellent sense of motion with realistic wheel blur and road lines.
- + Great preservation of the car's lighting and body shape.
- + Good integration of the background into the scene.
- − The man's face and hair are significantly altered from the source image.
- − The man's clothing is simplified and loses the distinct pattern of the source.
FLUX.2 [max]
- + Stronger preservation of the man's physical features and unique hairstyle.
- + Accurately replicates the specific plaid pattern and scarf from the source photo.
- + Beautifully rendered California coastline with high clarity.
- − The car looks static as if it is parked on the road rather than driving.
- − Odd artifacting on the back of the car's passenger headrest.
Verdict: Both models handled the complex task of merging two distinct subjects into a new environment well. FLUX.2 [max] is the winner because it successfully preserved the specific identity and wardrobe of the man from the source image, whereas FLUX.2 [klein] 4B generated a somewhat generic person. While FLUX.2 [klein] 4B better captured the sense of 'driving' with motion blur, FLUX.2 [max] produced a higher-fidelity edit that honored the source material more closely.
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
FLUX.2 [max]
AI Judge Analysis
FLUX.2 [klein] 4B
- + Excellent depiction of light rain and atmospheric depth.
- + Highly realistic skin textures and facial expression.
- + Captures the requested 'imperfect framing' naturally.
- − The cars in the background lack the requested motion blur.
- − The bike's rear wheel and chain assembly have some anatomical inconsistencies.
- − The bike appears too small relative to the man's scale.
FLUX.2 [max]
- + Successfully incorporates motion blur from passing cars.
- + The interaction between the man's hands and the wheel feels more like actual 'repairing'.
- + Excellent texture on the wet pavement and clothing.
- − The bicycle frame geometry is slightly warped/nonsensical near the seat post.
- − Composition is a bit more staged and less 'candid' than Image A.
- − The background bokeh is a bit busy compared to the requested 50mm look.
Verdict: Both models performed exceptionally well on the realism and atmospheric requirements. FLUX.2 [klein] 4B (Image A) captures a more emotive and candid 'street photography' vibe with superior facial detail, but fails to include the requested motion blur. FLUX.2 [max] (Image B) is more technically accurate to the prompt by including the motion blur and a more logical 'repairing' action, though the bicycle's frame is physically impossible in some areas.
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
FLUX.2 [max]
AI Judge Analysis
FLUX.2 [klein] 4B
- + Symmetrical and clear armor engraving
- + Accurate depiction of hair braided with beads
- + Effective use of warm torchlight on the skin and metal
- − Lighting feels a bit flat compared to the other model
- − The background torches are somewhat distracting and less bokeh-style than requested
FLUX.2 [max]
- + Excellent battle-worn aesthetic with realistic dirt and grimy textures
- + Superior lighting contrast and shallow depth of field
- + Highly detailed rendering of frayed cloth and leather straps
- − The braids are less distinct and partially hidden by the armor's angle
- − The character's expression is slightly more menacing than a typical paladin archetype
Verdict: While FLUX.2 [klein] 4B provides a very clean and symmetrical portrait that hits all the prompt points, FLUX.2 [max] delivers a more cinematic and realistic interpretation. FLUX.2 [max] excels in textural detail—specifically the grit on the skin and the frayed edges of the underlayer—and creates a much better sense of atmosphere through its lighting and depth of field.
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
FLUX.2 [max]
AI Judge Analysis
FLUX.2 [klein] 4B
- + Excellent photographic quality and food styling
- + Strict adherence to the grid-based layout mentioned in the prompt
- + Clean, professional typography that feels high-end
- − Text is mostly gibberish with character distortions
- − The category headings (Mains, Malts) are repetitive or incorrectly spelled
FLUX.2 [max]
- + Clearer text rendering with intelligible category headers
- + Stronger use of vibrant color accents through the yellow and red headers
- + Distinct and logical sections for different food types
- − Image grid is less balanced than Model A
- − Many food items listed under 'Pizza' are not actually pizzas
- − The design feels a bit more like a fast-food flyer than a professional minimalist restaurant menu
Verdict: FLUX.2 [klein] 4B produces a much more sophisticated and visually appealing aesthetic with professional food photography, though it struggles with legible text. FLUX.2 [max] follows the specific content sections better and provides readable text, but the overall design is less polished. FLUX.2 [klein] 4B is the winner for its superior composition and minimalist execution.
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
FLUX.2 [max]
AI Judge Analysis
FLUX.2 [klein] 4B
- + Successfully renders the price starburst and secondary text correctly.
- + Excellent background lighting and depth with realistic embers.
- − The main title 'MAGIC BURGER' is horribly garbled and misspelled.
- − Fails the 'exploded' prompt as the burger is largely assembled.
FLUX.2 [max]
- + Perfectly renders all requested text with the correct fiery effect.
- + Deep adherence to the 'exploded' concept with floating ingredients and sauce.
- + Clean and vibrant starburst graphic for the price.
- − The 'exploded' effect creates a slight visual gap in the middle that feels less cohesive than a professional ad.
Verdict: FLUX.2 [max] is the clear winner as it followed every instruction, including the difficult 'exploded' burger layout and perfect rendering of all text strings. FLUX.2 [klein] 4B failed to spell the product name correctly and produced a standard burger instead of the requested exploded view.
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
FLUX.2 [max]
AI Judge Analysis
FLUX.2 [klein] 4B
- + Features a very convincing chalk-on-board texture including dust smudges and eraser marks.
- + Consistent cursive handwriting style across all menu items.
- − Numerous spelling errors including 'Trufffl', 'Musheram', 'Ootrpous', 'Brawn', and 'daly'.
- − The title has a strange spacing error in 'S PECIALS'.
FLUX.2 [max]
- + Almost perfect spelling across the entire board, including the complex menu items.
- + Excellent lighting and composition with the overhead lamp and wood paneling background.
- + Very natural handwriting style that adheres strictly to the prompt instructions.
- − The word 'Specials' in the title has slightly inconsistent letter thickness compared to 'Today's'.
Verdict: FLUX.2 [max] is the clear winner as it followed the complex text requirements perfectly with virtually no spelling errors, whereas FLUX.2 [klein] 4B struggled significantly with the spelling of almost every word. FLUX.2 [max] also provided a more atmospheric composition with better lighting and environmental details.
Pose & Character Mashup
EditingEdit instruction
“Use Image 1 as the exact pose reference and Image 2 as the character reference. Recreate the person/character from Image 2 in the exact dynamic pose and body position from Image 1. Keep the exact face, hair, clothing style/details, and expression from Image 2. Match the lighting and environment of Image 1. The final image must show the character from Image 2 performing the precise action/pose from Image 1 with perfect anatomy and natural integration.”
Source
FLUX.2 [klein] 4B
FLUX.2 [max]
AI Judge Analysis
FLUX.2 [klein] 4B
- + Successfully replicates the complex leg-crossing pose from Image 1.
- + Incorporates the clothing and scarf elements from Image 2.
- + Maintains the bright yellow studio lighting of the source pose image.
- − Gives the male character long feminine hair from Image 1 instead of his own hair.
- − Faces are slightly distorted and skin texture appears waxy.
- − Left hand anatomy is awkward and blended.
FLUX.2 [max]
- + Correctly preserves the short hair and facial features of the character from Image 2.
- + Excellent anatomical detail on the feet and hands.
- + Seamless integration of the character's clothing style (sweatpants and graphic tee) into the new pose.
- − Slightly simplifies the leg pose, missing the tight cross present in Image 1.
- − The skin tone is significantly darker than the reference character.
Verdict: Both models do an impressive job of merging the two images, but FLUX.2 [max] is the superior choice because it correctly identifies that the hair from Image 1 belonged to the pose model, not the character. FLUX.2 [klein] 4B erroneously gives the man long flowing hair, whereas FLUX.2 [max] maintains character consistency while successfully executing the difficult dynamic pose and environment matching.
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
FLUX.2 [max]
AI Judge Analysis
FLUX.2 [klein] 4B
- + Excellent anatomical detail on the horse and astronaut suit
- + Creative interpretation showing the horse walking on the planet's atmosphere with a visible shadow
- + Consistent lighting and high-resolution textures
- − The astronaut's face inside the visor looks slightly low-resolution compared to the rest of the image
- − The reins physically clip through the astronaut's glove
FLUX.2 [max]
- + Beautiful cinematic lighting and lens flare effects
- + Strong composition with the asteroid providing a grounded anchor in the scene
- + Realistic reflection of stars and space on the helmet visor
- − The horse's hind legs have some anatomical confusion where they meet the asteroid
- − The astronaut's left hand position is a bit awkward
Verdict: Both models followed the complex prompt correctly, placing the astronaut on top of the horse. FLUX.2 [klein] 4B is preferred for its clever surrealism, showing the horse casting a shadow and creating dust on the upper atmosphere of Earth, while FLUX.2 [max] offers a more traditional but visually stunning cinematic space landscape.
Outfit Transfer Challenge
EditingEdit instruction
“Use Image 1 as the base person. Dress them in the exact elaborate outfit from Image 2 (including all layers, accessories, jewelry, and shoes). Carefully adapt the clothing to the body shape and pose in Image 1 while maintaining realistic fabric behavior, correct proportions, and perfect lighting/shadow matching. Keep the person’s exact face, hair, and background completely unchanged.”

FLUX.2 [max]
AI Judge Analysis
FLUX.2 [klein] 4B
- + Successfully replicates the specific plaid pattern and layering of the scarf.
- + Preserves the face and vitiligo skin patterns with high accuracy from the source image.
- + Captures the accessories like the gold rings and watch reasonably well.
- − The coat is missing the internal shirt/sweater layer, leaving the chest exposed which contradicts the source outfit.
- − Lighting on the character is slightly harsher and less natural than the background environment.
FLUX.2 [max]
- + Perfectly replicates the full outfit including the black shirt under the coat, which Model A missed.
- + Excellent preservation of the subject's face, hair, and specific skin details.
- + Superior lighting integration, making the subject feel realistically placed within the beach scene.
- − A minor white tag or artifact is visible on the bottom of the scarf.
- − Slightly less detail in the grit/sand texture on the face compared to the source.
Verdict: Both models performed exceptionally well at preserving the identity of the subject from Image 1 while applying the attire from Image 2. FLUX.2 [max] is the winner because it correctly included the black under-layer of the outfit and achieved better lighting and shadow integration, whereas FLUX.2 [klein] left the character shirtless under the heavy coat.
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
FLUX.2 [max]
AI Judge Analysis
FLUX.2 [klein] 4B
- + Successfully rendered capybara paws on the steering wheel.
- + High level of detail in the capybara's fur and the businesswoman's expression.
- + Excellent composition that captures both front and back seat clearly.
- − The car interior feels a bit small or cramped for a standard New York taxi.
FLUX.2 [max]
- + Good cinematic lighting with the glow from the smartphone.
- + Accurate New York taxi driver style hat.
- − Anatomical failure with human hands emerging from the capybara's sleeves.
- − The woman is looking at her phone but is very blurry compared to the driver.
Verdict: FLUX.2 [klein] 4B is the clear winner because it correctly depicts capybara paws on the steering wheel, whereas FLUX.2 [max] erroneously gives the capybara human hands. FLUX.2 [klein] 4B also provides a much sharper and more balanced composition with better adherence to the character descriptions.
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
FLUX.2 [max]
AI Judge Analysis
FLUX.2 [klein] 4B
- + Strong cinematic lighting with a great central glow effect
- + Followed the border instructions well with webs and thorns
- + Good balance of atmospheric elements like the bats and twisted trees
- − Significant spelling errors in the main title and event details
- − Date is missing a digit (206 instead of 2026)
- − Text legibility is lower due to font styling issues
FLUX.2 [max]
- + Perfect text accuracy for all requested fields
- + High-quality rendering of the jack-o-lantern and textures
- + Excellent layout with a clearly defined scroll banner
- − The thorns in the border are slightly less defined than the other model
- − Small typo in the banner font ('fright s' has a slight space)
- − Slightly less 'parchment' texture in the center sky area
Verdict: While both models followed the visual prompt well, FLUX.2 [max] is the clear winner due to its superior text rendering. FLUX.2 [klein] 4B suffered from major spelling errors in the title ('Hallbwom') and the date, whereas FLUX.2 [max] delivered perfectly legible and accurate invitation details.

AI Judge Analysis
FLUX.2 [klein] 4B
- + Excellent realistic hair texture with fine, individual strands and natural flyaways.
- + Perfectly preserved all original facial features, background, and lighting.
- + The hairline integration with the forehead is very natural.
- − The hair length is quite long, which some might find slightly messy for the intended request.
FLUX.2 [max]
- + Successfully added a thick, full head of hair.
- + Preserved the base image characteristics well.
- − The hairline is a bit high and stiff, appearing slightly artificial at the temples.
- − The overall hair volume is somewhat blocky and lacks the fine textural detail seen in the other version.
Verdict: Both models handled the image editing task well without altering the source person's face or the background. FLUX.2 [klein] 4B is the winner because it provides much more realistic hair texture with organic-looking strands and a more convincing hairline, whereas FLUX.2 [max] produced hair that looks a bit more like a wig.
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
FLUX.2 [max]
AI Judge Analysis
FLUX.2 [klein] 4B
- + Excellent realistic PBR material textures on the fish and rice.
- + Clean, high-clarity rendering with professional lighting.
- + Accurate sushi anatomy for nigiri.
- − Missed the small flag icon requirement, showing a generic red/white bar.
- − Failed to render the word 'SUSHI' correctly (rendered as 'SUSH').
- − Omitted the 'diorama base' requested in the prompt.
FLUX.2 [max]
- + Perfectly followed the 'diorama base' and isometric framing instructions.
- + Accurate text rendering for both 'JAPAN' and 'SUSHI'.
- + Included a correct Japanese flag icon as requested.
- − The textures are very matte/flat compared to the requested 'realistic PBR' style.
- − The stylized 3D models look more like plastic toys than high-end food renders.
Verdict: FLUX.2 [max] is the clear winner for its superior prompt adherence, correctly rendering all text, the flag, and the isometric diorama base. While FLUX.2 [klein] 4B had much better material realism for the food itself, it failed significantly on the text and the specific composition elements requested.
Over-the-top cartoon caricature
EditingEdit instruction
“Create a caricature of me and my job. Make it exaggerated and humorous, incorporating my profession as a tv show anchor and my love for dogs and hockey.”
Source
FLUX.2 [klein] 4B
FLUX.2 [max]
AI Judge Analysis
FLUX.2 [klein] 4B
- + Captures the woman's facial features and eye color with higher fidelity to the source image
- + Successfully incorporates the 'tv show anchor' profession through the desk and newsroom setting
- − Fails to include any hockey-related elements, missing a key part of the prompt
- − The cross-eyed caricature style is perhaps a bit more unsettling than humorous
FLUX.2 [max]
- + Excellent adherence to all prompt elements, combining news anchor, dogs, and hockey gear efficiently
- + High-quality caricature style with great lighting and vibrant colors
- + Preserves the denim shirt from the source image
- − The eyes are changed to a bright blue, losing the brown eye color from the source image
- − The face is more generic and less recognizable as the woman in the source compared to Model A
Verdict: FLUX.2 [max] is the winner because it successfully integrated all three requested themes: the news anchor profession, the dogs, and the hockey elements. While FLUX.2 [klein] 4B captured the likeness of the subject's face slightly better, it completely ignored the hockey portion of the prompt and lacked the creative composition found in the other 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.”
FLUX.2 [klein] 4B
FLUX.2 [max]
AI Judge Analysis
FLUX.2 [klein] 4B
- + Excellent warmth and vibrant color saturation.
- + Beautiful lighting with clear 'god rays' effects.
- + Good fur textures and expressive eyes.
- − Failed to include the baby bunny, providing two kittens instead.
- − The fox's anatomy is slightly stiff compared to the others.
FLUX.2 [max]
- + Successfully included all requested animals: puppy, kitten, bunny, and fox.
- + Superior sense of movement and 'tumbling' as requested.
- + Incredible detail in dew sparkles and soft fur textures.
- − The lighting is a bit more muted and hazy compared to the warmth of the first image.
Verdict: FLUX.2 [max] is the clear winner because it followed the checklist of animals perfectly, whereas FLUX.2 [klein] 4B replaced the bunny with a second kitten. FLUX.2 [max] also captured a better dynamic action of the animals playing and included much finer details like the dew drops on the grass.
Studio Ghibli Anime Style
EditingEdit instruction
“Transform this photo into a Studio Ghibli–inspired illustration. Use soft pastel colors, hand-painted textures, gentle lighting, dreamy backgrounds, and a warm, nostalgic mood”
Source
FLUX.2 [klein] 4B
FLUX.2 [max]
AI Judge Analysis
FLUX.2 [klein] 4B
- + Excellent transfer of original poses and clothing details.
- + Delicate watercolor-style background transitions.
- + Clean line art that captures the 'shoujo' influence of some Ghibli films.
- − Loses the facial expression of the girlfriend, making her look happy instead of jealous.
- − The color palette is a bit washed out, lacking contrast.
FLUX.2 [max]
- + Successfully preserves the 'jealous/angry' facial expression of the girlfriend.
- + Captures the iconic Ghibli hand-painted texture and warmer color palette more effectively.
- + Maintains the structural elements of the original photo with higher fidelity.
- − The grain/texture overlay is a bit heavy-handed in some areas.
- − The eyes feel slightly generic compared to the specific source characters.
Verdict: Both models did an impressive job of translating a famous meme into an illustration style. While FLUX.2 [klein] 4B followed the 'pastel' instruction well, it failed to maintain the emotional context of the scene by making the girlfriend look pleased. FLUX.2 [max] is the winner because it successfully captured the requested aesthetic while preserving the narrative tension and specific facial expressions from the original image.
Golden Hour Stroll
Image EditingEdit instruction
“Add dynamic motion to this photo: make hair blow in the wind, add leaves flying, energetic and lively feel.”
FLUX.2 [klein] 4B
FLUX.2 [max]
AI Judge Analysis
FLUX.2 [klein] 4B
- + Excellent preservation of the original subjects' faces and clothing details.
- + Adds a high quantity of leaves that fill the scene uniformly.
- + Good wind-blown hair effect that looks natural to the person.
- − The added leaves appear somewhat 'pasted on' with consistent sharp focus regardless of depth.
- − Leaves are brown and dry, which slightly clashes with the lush green background.
FLUX.2 [max]
- + Natural motion blur on the leaves adds a realistic sense of speed and wind.
- + Hair motion is more pronounced and dynamic than the other model.
- + Leaves are colored to match the local green environment better.
- − Noticeable alteration to the woman's facial features compared to the source image.
- − Source preservation is slightly lower with changes to clothing texture and hand positioning.
Verdict: Both models successfully interpreted the dynamic motion instructions, but FLUX.2 [klein] 4B is better at source preservation, keeping the woman's face nearly identical to the original. However, FLUX.2 [max] produced a more convincing 'dynamic' effect with realistic motion blur on the leaves and a stronger wind effect in the hair, even though it slightly altered the character's likeness.
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
- + Clean vector emblem style with sharp silhouettes.
- + Correctly includes the requested textured light background.
- + Accurately renders the 'Est. 1720' text in a banner.
- − Misspells the primary restaurant name as 'FLAXTION'.
- − Redundant text repetition with 'Est. 1720' appearing twice.
- − The cloche design feels a bit heavy and less elegant compared to the prompt's vintage request.
FLUX.2 [max]
- + Perfectly spells the restaurant name 'Caffè Florian'.
- + Elegant circular composition that fits the 'vintage minimalist' theme better.
- + Superior rendering of the steam and cloche details.
- − The banner for 'Est. 1720' is slightly less prominent than Image A's.
- − Line weight on the outer circle is a bit thin for a vector emblem.
Verdict: FLUX.2 [max] is the clear winner because it correctly spelled the restaurant name, whereas FLUX.2 [klein] 4B hallucinated the name as 'FLAXTION'. FLUX.2 [max] also provided a more balanced, professional-looking circular emblem that felt more aligned with a 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.”
FLUX.2 [klein] 4B
FLUX.2 [max]
AI Judge Analysis
FLUX.2 [klein] 4B
- + Successfully captures a vintage muted NASA color palette.
- + Includes silhouettes of the three astronauts as requested in the 'supporting' part of the prompt.
- − Text rendering is mostly gibberish or misspelled (e.g., 'APLLO', 'Oborot').
- − The layout is disorganized and creates an illogical flow for an infographic.
- − Includes two Earths and fails to show a clear step-by-step progression.
FLUX.2 [max]
- + Excellent typography with mostly correct spelling and clear, readable labels.
- + Logical step-by-step layout that follows the requested narrative sequence.
- + Consistent iconography and professional vector-style aesthetic.
- − Repetitive labels (labels the first three panels as 'Earth Orbit' at the top).
- − The astronaut silhouettes look like modern airline pilots rather than NASA astronauts.
Verdict: FLUX.2 [max] significantly outperforms FLUX.2 [klein] 4B by providing a coherent, readable infographic with a logical flow. While FLUX.2 [max] has some label repetitions, its ability to render legible text and follow the specific step-by-step instructions makes it a much more functional design compared to the garbled text and messy layout of FLUX.2 [klein] 4B.
