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
FLUX1.1 [pro]
- + Excellent refractions and reflections in the glass edges
- + Creative choice to have the sphere floating central to the cube
- + Strong adherence to the 'light from the left' instruction
- − The glass enclosure is a tall rectangular prism rather than a cube
- − The red book looks more like a thin lid than a standalone book
LongCat-Image
- + Accurately depicts a cube shape
- + Very realistic book texture and page detailing
- + Perfect placement of the plant behind the glass as requested
- − The sphere is slightly cut off at the bottom by a reflection
- − The lighting on the cube edges is a bit less dynamic than Model A
Verdict: Both models followed the prompt instructions well, including the lighting and object placement. LongCat-Image is the winner because it actually rendered a cube, whereas FLUX1.1 [pro] rendered a tall rectangular prism, and LongCat-Image provided much better detail on the red book.
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
FLUX1.1 [pro]
- + Excellent bokeh and background depth
- + Convincing wet pavement texture and reflections
- + Realistic skin texture and age details
- − The bicycle geometry is broken with the frame appearing severed behind the front wheel
- − An extra small wheel or object appears behind the man's feet
- − The man is holding the handlebars rather than repairing the bike
LongCat-Image
- + Stronger adherence to the 'repairing' action with a crouching pose
- + Good visible rain effects and street atmosphere
- + More coherent Japanese street setting with appropriate signage and architecture
- − Severe anatomical issues with the bicycle having three wheels and overlapping frames
- − The car in the background looks slightly distorted
- − Visible rain streaks look a bit like static lines rather than natural droplets in some areas
Verdict: Both models struggled significantly with the complex geometry of a bicycle. FLUX1.1 [pro] produced a more professional, cinematic photo with superior lighting and texture, but the bicycle frame is physically impossible. LongCat-Image followed the 'repairing' prompt better by showing the man crouching and working on the bike, but it hallucinated a third wheel and suffered from major coherence issues with the bicycle's structure.
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
FLUX1.1 [pro]
- + Exceptional realism in skin texture, pores, and hair detail
- + Masterful use of shallow depth of field and bokeh sparks
- + Intense and lifelike eye rendering
- − The braids are less distinct and more messy compared to the prompt's likely intent
- − The armor engraving is partially obscured by the tight framing
LongCat-Image
- + Excellent adherence to the 'braids with small beads' requirement
- + Beautifully engraved plate armor with clear texture on straps and gambeson
- + Stronger narrative composition showing the full upper torso and torchlight source
- − Skin texture and scars look somewhat painted or artificial compared to Model A
- − The facial features are slightly generic
Verdict: FLUX1.1 [pro] excels in raw visual fidelity and photographic quality, capturing a visceral, battle-worn look with incredible skin and eye detail. However, LongCat-Image followed the specific stylistic prompts (beads in braids, texture on straps and cloth) much more accurately and provided a more balanced composition that showcases the ornate armor.
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
FLUX1.1 [pro]
- + Excellent professional presentation with realistic silverware context.
- + Clean and organized grid layout that follows modern design trends.
- + Better adherence to the 'minimalist' and 'professional' requested vibe.
- − Text rendering is somewhat garbled and mostly illegible.
- − The food photos in the grid lack variety in color compared to the prompt's request for vibrance.
LongCat-Image
- + Stronger use of vibrant colored accents as requested in the prompt.
- + Food photography and colors are more saturated and appetizing.
- + Closer to a grid-based layout for the sectioning.
- − Typography is chaotic, with very poor font choice and illegible text.
- − Overall design feels less professional and more like a cluttered template.
- − Lacks the sophistication of a 'modern minimalist' restaurant design.
Verdict: FLUX1.1 [pro] provides a much more polished and realistic interpretation of a professional menu, including high-quality product photography and a cohesive layout. While LongCat-Image uses more vibrant colors, it fails to achieve a minimalist or professional aesthetic, resulting in a cluttered design with poor typography. FLUX1.1 [pro] is the clear winner for its superior composition and professional feel.
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
FLUX1.1 [pro]
- + Excellent photorealistic lighting and depth of field
- + Accurate rendering of the price '€6.99' in the requested currency
- − Failed the 'exploded' instruction as the burger is mostly assembled
- − Text is repetitive with 'Magic Burger' appearing twice in different styles
LongCat-Image
- + Highly accurate text integration including the fiery effect and starburst shape
- + Dynamic composition with a strong sense of 'Magic Burger' branding
- + Background elements like glowing coals align well with the theme
- − The burger is not truly 'exploded' with suspended components as requested
- − Minor sauce artifacts near the top bun look slightly unnatural
Verdict: While both models failed to fully 'explode' the burger components into mid-air, LongCat-Image captured the marketing aesthetic much better, following the complex text instructions and starburst requirement perfectly. FLUX1.1 [pro] produced a more photorealistic image but struggled with the layout and repeated the title twice which was not requested.
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
FLUX1.1 [pro]
- + Excellent text legibility and accuracy compared to the prompt.
- + Atmospheric lighting and professional composition.
- + Authentic chalk-on-blackboard aesthetic with natural variations.
- − Hallucinated an extra line for 'Grilled Octopus' and significantly changed the prices.
- − Included a slight spelling error 'Chipkies' and 'Herbss' in the list.
LongCat-Image
- + Stronger 'chalky' texture with dust effects on the board.
- + Good use of space and font-like variation in the title.
- − Heavy spelling errors and garbled text across the entire board.
- − Did not follow the specific wording 'Truffle Mushroom Risotto' or 'Grilled Octopus' correctly.
- − The 'handwriting' looks more like a digital font than natural chalk writing.
Verdict: FLUX1.1 [pro] significantly outperforms LongCat-Image by producing legible, coherent text that follows the prompt's structural requirements, despite some price hallucinations. LongCat-Image fails to render the specific requested words, resulting in garbled text that is difficult to read.
The Reversed Rodeo
Text-to-Image“Horse riding astronaut in space — horse on top, not vice versa. Surreal, highly detailed, cinematic.”
AI Judge Analysis
FLUX1.1 [pro]
- + Excellent cinematic lighting and texture details on the astronaut suit and horse hair.
- + Dynamic and balanced composition with a surreal, cloud-like atmosphere.
- − Completely failed the negative constraint to have the horse on top of the astronaut.
LongCat-Image
- + Includes interesting sci-fi elements like a lunar base and space planes.
- + High clarity and sharp focus throughout the entire scene.
- − Completely failed the core prompt logic of having the horse on top of the astronaut.
- − Anatomical issues with the horse's legs appearing elongated and stiff.
Verdict: Both models failed the specific prompt instruction to place the horse on top of the astronaut, instead defaulting to the cliché astronaut-riding-a-horse image. FLUX1.1 [pro] is the winner simply due to its superior artistic quality, cinematic lighting, and realistic textures, whereas LongCat-Image feels more like a disjointed collage with anatomical distortions.
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
FLUX1.1 [pro]
- + Excellent interior lighting and atmospheric bokeh in the background
- + High quality texture on the capybara's fur and the woman's coat
- + Successfully captures the specific requested 'bored' expression of the passenger
- − The perspective is confusing, making the passenger appear as if she is in the front seat next to the driver
- − The steering wheel is not visible, failing a specific part of the prompt
LongCat-Image
- + Perfectly adheres to the composition of a driver in front and passenger in the back
- + Successfully renders the capybara with paws on the steering wheel as requested
- + Sharp, clear details with a realistic taxi exterior and roof sign
- − Shows two passengers instead of one, and their placement is slightly repetitive/glitched
- − The capybara's paw looks more like a human hand with long claws rather than a natural paw
Verdict: LongCat-Image provides a much better interpretation of the requested scene layout, showing the capybara actually driving the vehicle with a clear distinction between the front and back seats. While FLUX1.1 [pro] has superior lighting and textures, its failure to place the passenger in the back and the absence of the steering wheel makes it a less accurate response to 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
FLUX1.1 [pro]
- + Excellent cinematic lighting and atmosphere.
- + Clean, professional illustration style.
- + Follows the square format requested.
- − Several typos in the text including 'inivted' and 'frightss'.
- − Redundant text elements with information appearing twice.
- − Failed to include the specific title string accurately.
LongCat-Image
- + Perfectly rendered headline text with no spelling errors.
- + Matches the 'dark parchment' and 'thorns and webs' request more literally.
- + Included all requested text elements in a clear hierarchy.
- − The location text 'The Arches' is misspelled as 'The Armiees'.
- − The composition feels a bit cluttered with the sharp thorn border.
- − The transition between the parchment and the central scene is a bit harsh.
Verdict: LongCat-Image is the superior choice because it successfully renders the complex headline and banner text accurately, whereas FLUX1.1 [pro] suffers from several typos and strange text repetitions. While FLUX1.1 [pro] has a more cohesive artistic style, LongCat-Image better follows the layout instructions for the vintage parchment poster.
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
FLUX1.1 [pro]
- + Excellent variety of sushi items on the diorama base.
- + Soft and consistent 3D cartoon lighting and texture.
- + Clean and professional typography layout.
- − Missed the small flag icon requested in the prompt.
- − The text 'SUSHI' is a bit thin and loses legibility compared to 'JAPAN'.
LongCat-Image
- + Successfully included the small flag icon as requested.
- + Very high attention to tactical PBR textures, especially on the fish and rice.
- + Strong, bold text rendering for both 'JAPAN' and 'SUSHI'.
- − The red fish topping has a slightly distorted, drooping shape on the right side.
- − Less variety in the sushi selection compared to Model A.
Verdict: LongCat-Image is the overall winner because it successfully followed all prompt instructions, including the specific request for a small flag icon and bold text. While FLUX1.1 [pro] created a more visually diverse diorama, LongCat-Image's superior texture work and strict adherence to the requested elements make it the more accurate response.
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
FLUX1.1 [pro]
- + Excellent soft lighting with convincing god rays and rim lighting on fur.
- + High artistic quality with a consistent, dreamy color palette.
- + Superior rendering of 'expressive eyes' and realistic fur texture.
- − Failed to include the red fox kit from the prompt.
- − Missing the tabby kitten (the cat pictured is ginger).
- − The animals are sitting rather than 'tumbling and chasing'.
LongCat-Image
- + Included all four animals requested: puppy, kitten, bunny, and fox.
- + Captured the 'chasing' and 'tumbling' movement more effectively.
- + Good interpretation of 'dew sparkles' using floating water droplets.
- − Anatomical failure on the kitten, which has distinct rabbit ears.
- − The fox kit has a slightly cartoonish, stiff appearance compared to the puppy.
- − Visual quality is less 'hyper-photorealistic' and more like a digital composite.
Verdict: FLUX1.1 [pro] produced a much more beautiful and high-quality image with superior lighting and texture, but it failed significantly on prompt adherence by missing half of the requested animals. LongCat-Image attempted all elements of the prompt but suffered from a major anatomical error (merging the cat and rabbit) and a less realistic aesthetic. FLUX1.1 [pro] is the winner for overall visual masterpiece quality despite the missing subjects.
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
FLUX1.1 [pro]
- + Excellent vector emblem aesthetic with clean lines.
- + Perfect adherence to color scheme and vintage style.
- + High symmetry and профессиональный balance.
- − Spelling error in the main text ('FRANILIAN' instead of 'FLORIAN').
- − The central element looks more like a decorative dome/cupola than a restaurant cloche.
LongCat-Image
- + Correct spelling of 'Caffè Florian'.
- + Clearly depicts a restaurant cloche dome as requested.
- + Great use of subtle texture on the background.
- − Awkward repetition of the word 'Caffè' stacking on top of itself.
- − Typography is less cohesive and elegantly integrated than Model A.
- − Line work is slightly less refined for a 'vector emblem' style.
Verdict: Model A (FLUX1.1 [pro]) produces a much more professional and aesthetically pleasing logo design, but fails significantly on the requested text spelling. Model B (LongCat-Image) follows the text requirements and cloche dome prompt more literally but suffers from a cluttered composition and awkward text repetition. Model B is the narrow winner for providing the correct name, despite Model A's superior graphic quality.
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
FLUX1.1 [pro]
- + Excellent typography for the main title and numbering
- + Cleaner composition with a more sophisticated modern vector aesthetic
- + Better adherence to the 'navy, white, muted red' NASA color palette
- − Step numbers are redundant and confusingly labeled (e.g., two '6's and a '5' out of sequence)
- − Small text is largely illegible gibberish
LongCat-Image
- + Clearer icon-driven layout for the individual steps
- + Includes relevant symbols like the American flag and lunar module icons
- + Follows the flat-vector style nicely
- − Text rendering is poor with significant misspellings of the main title
- − Composition is disjointed and lacks the professional infographic feel
- − Only captures three major steps rather than the requested six
Verdict: FLUX1.1 [pro] produced a more visually cohesive and professional-looking poster that accurately followed the requested color palette and vector style. While its internal numbering and small text were flawed, LongCat-Image struggle significantly with basic text rendering and only included half of the requested steps.
