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 Krea [dev]
- + Excellent photorealistic textures on the book and table.
- + Strong lighting and reflection work on the blue sphere.
- − Failed to show the plant through the glass of the cube.
- − The perspective of the table edge is slightly unnatural.
Seedream 4.0
- + Perfect adherence to the prompt, including the plant being visible through the glass.
- + Naturalistic lighting with soft window shadows on the table.
- + Accurate spatial arrangement of all components.
- − The glass cube edges are a bit thin and lack weight compared to Model A.
- − The blue sphere has less intricate internal reflections.
Verdict: While FLUX.1 Krea [dev] produced a more high-end, textured photographic look, it failed to place the plant behind the cube as requested. Seedream 4.0 followed every detail of the prompt accurately, successfully showing the green plant through the glass and capturing the requested lighting effect perfectly.
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 Krea [dev]
- + Captures the motion blur from a passing car effectively.
- + Excellent rendering of wet pavement reflections and raindrops.
- − The man is standing and holding the bike rather than actively repairing it.
- − The bicycle has structural issues, specifically the seat and handlebars are misaligned.
Seedream 4.0
- + Strongly adheres to the 'repairing' aspect of the prompt with tools and an appropriate posture.
- + Includes clear reflections in puddles for added realism.
- + Achieves a convincing candid street photography aesthetic.
- − The man's right hand has anatomical errors with blended fingers.
- − The spokes on the front wheel are messy and physically impossible.
Verdict: Seedream 4.0 followed the prompt more closely by showing the man actively repairing the bike with tools, whereas FLUX.1 Krea (dev) showed him simply standing with it. However, both models struggled with the mechanical complexity of the bicycle, though Seedream 4.0 captured the 'candid' and 'imperfect framing' look better.
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 Krea [dev]
- + Exquisite engraving detail on the plate armor
- + Highly realistic skin textures with convincing grime
- + Clean and symmetrical composition
- − Lighting feels a bit static and studio-like rather than torch lit
- − The hair beads are very subtle and blend into the hair
Seedream 4.0
- + Dynamic lighting with a visible torch and warm glow
- + More characterful braids with distinct colorful beads
- + Better representation of battle-worn leather and fabric textures
- − The sparks have motion blur which slightly conflicts with the 'bokeh' request
- − The facial anatomy is slightly less consistent than Model A
Verdict: FLUX.1 Krea [dev] produces a technically superior image in terms of detail and texture, particularly on the metallic surfaces and skin. However, Seedream 4.0 better captures the requested 'warm torchlight' atmosphere and 'beads' in the hair, offering a more vibrant and cinematic interpretation.
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 Krea [dev]
- + Excellent professional layout following the grid request
- + Includes logical sections for Appetizers and Mains with prices
- + Highly realistic food photography integrated cleanly into the design
- − Text consists of gibberish/placeholder characters
- − Repeats the 'Appetizers' section header
Seedream 4.0
- + Legible bold sans-serif category headers
- + High-quality, vibrant food photography
- + Clean white background
- − Lacks an actual menu structure with item descriptions or prices
- − Atypical layout that feels more like a collage than a functional restaurant menu
- − Missing 'Pizza' logic in the grid relative to the headers
Verdict: FLUX.1 Krea [dev] successfully creates a professional, functional menu design with a sophisticated grid layout, despite the text being unintelligible. Seedream 4.0 produces a simple collage of food with headers, failing to capture the complexity of a 'menu design' as requested in the prompt.
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 Krea [dev]
- + Excellent text legibility and clean graphic design layout.
- + High photorealistic detail on the textures of the bun and meat patty.
- + Accurate representation of the requested price and currency.
- − The burger components are mostly stacked rather than 'exploded' or suspended with a sense of motion.
- − The background fire feels like a flat element at the bottom rather than an immersive environment.
Seedream 4.0
- + Superior sense of motion with dynamic swoosh effects and tilted angles.
- + Perfectly follows the 'fiery, glowing effect' instruction for the text typography.
- + Highly creative composition that feels like a professional action-oriented advertisement.
- − Incorrectly rendered the price as €5.99 instead of the requested €6.99.
- − The burger appears to be split into two separate mini-burgers rather than one exploded stack.
Verdict: FLUX.1 Krea (dev) produced a very clean and accurate advertisement with perfect text, but it lacked the requested sense of 'suspended motion' and 'exploded' dynamics. Seedream 4.0 captures the artistic energy and fiery aesthetic of the prompt much better, though it failed to get the specific price correct. Seedream 4.0 is the preferred choice for a creative brief emphasizing motion, despite the small numerical error.
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 Krea [dev]
- + Excellent typography rendering with minimal errors
- + Clean and well-centered composition
- + Accurate representation of an indoor wall-mounted chalkboard
- − Text style for the items feels slightly too uniform/digital compared to chalk
- − Includes hallucinated menu items like 'Gruffle Mushroom' and 'Grilled Butter'
- − Missed some specific wording from the prompt like 'Lemon & Herbs'
Seedream 4.0
- + Highly realistic chalk texture with smudges and dust
- + Perfect adherence to all requested menu text and prices
- + Authentic 'cozy café' background bokeh contributes to atmosphere
- − The perspective is slightly angled rather than straight-on
- − The date text is slightly cramped compared to the title
Verdict: While FLUX.1 Krea (dev) produced a very clean and legible board, it failed significantly on prompt adherence by hallucinating incorrect menu items. Seedream 4.0 followed the text prompt perfectly, capturing all specific menu items and prices while maintaining a much more realistic chalk texture and cozy atmosphere.
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 Krea [dev]
- + Excellent lighting and cinematic composition with the Earth in the background.
- + Highly detailed rendering of the astronaut suit and mechanical saddle.
- − Failed to follow the specific spatial instruction 'horse on top, not vice versa'.
- − Anatomical oddities where the horse and mechanical parts merge.
Seedream 4.0
- + Beautiful celestial background with galaxy and star clusters.
- + Strong lighting reflections on the astronaut's visor.
- − Failed to follow the specific spatial instruction 'horse on top, not vice versa'.
- − The horse's front legs appear distorted and incorrectly attached to the body.
Verdict: Both FLUX.1 Krea and Seedream 4.0 failed the specific spatial logic of the prompt, which requested the horse to be on top of the astronaut. While both models produced standard 'astronaut on a horse' images, FLUX.1 Krea is slightly better due to its cleaner composition and higher technical quality of textures.
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 Krea [dev]
- + Excellent texture on the capybara's fur
- + High legal text legibility on the hat
- + Strong cinematic lighting and composition
- − Includes an extra person in the passenger seat not mentioned in the prompt
- − The capybara only has one paw on the steering wheel instead of two
Seedream 4.0
- + Perfectly adheres to the character count with one driver and one passenger
- + Excellent depiction of both paws on the steering wheel as requested
- + Captures the bored, normal expression of the businesswoman well
- − Text on the hat is nonsensical ('TAT')
- − The capybara's head is slightly oversized for the car interior
- − A few artifacts on the passenger's hand holding the phone
Verdict: While FLUX.1 Krea [dev] has superior lighting and technical rendering, it failed the simple instruction of having a single passenger by adding an extra person in the front. Seedream 4.0 followed the prompt details much more accurately, correctly showing both paws on the wheel and the specific passenger arrangement requested.
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 Krea [dev]
- + Features a very clean and intricate cobweb border.
- + Includes all requested elements like bats, trees, and jack-o-lantern.
- + The jack-o-lantern rendering is very sharp with high contrast.
- − Several spelling errors in the text including 'Pasty Halloween' and 'nighhts'.
- − Text layout is a bit cluttered with redundant phrases.
Seedream 4.0
- + Excellent adherence to the 'thorns' part of the border prompt.
- + Superior text accuracy with almost perfect spelling of the entire invitation.
- + High-quality atmospheric lighting and cinematic background detail.
- − The text on the scroll banner is slightly warped/distorted.
- − The parchment effect is a bit heavy-handed, obscuring some corner details.
Verdict: Seedream 4.0 is the clear winner because it accurately followed the complex text instructions with minimal spelling errors, whereas FLUX.1 Krea [dev] failed on the main title by writing 'Pasty Halloween'. Seedream 4.0 also captured the 'thorns' aspect of the border much more effectively, creating a more cohesive gothic atmosphere.
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 Krea [dev]
- + Excellent adherence to the isometric perspective and diorama base requirement.
- + Clean, bold typography that perfectly matches the 'large bold text' instruction.
- + Minimalistic aesthetic that aligns well with the request for minimal garnish.
- − The salmon texture looks slightly more like a pattern than a realistic PBR material.
- − Composition feels a bit empty with only one piece of sushi.
Seedream 4.0
- + Provides a more detailed and diverse miniature scene with multiple types of sushi.
- + Beautiful lighting and soft, refined textures on the salmon and roe.
- + Includes clear flag icon integrated well with the text.
- − Fails the 'diorama base' instruction by placing the plate directly in the environment without a raised platform.
- − Perspective is slightly flatter than the requested 45° isometric angle.
Verdict: FLUX.1 Krea (dev) followed the structural prompt instructions more accurately, specifically the inclusion of a raised diorama base and the correct isometric perspective. Seedream 4.0 produced a more visually appealing variety of sushi with superior textures but ignored the architectural elements of the requested 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 Krea [dev]
- + Excellent character rendering with very clean, soft fur textures
- + Strong cinematic lighting and depth of field
- + Each animal has a clear, expressive face
- − Missed the baby bunny animal requested in the prompt
- − Replaced the rabbit with a second kitten
- − Action is mostly walking forward rather than 'tumbling together'
Seedream 4.0
- + Included all four distinct animals: golden retriever, kitten, rabbit, and fox
- + Perfectly captured the 'tumbling together' and 'chasing' aspect of the prompt
- + Superior rendering of dew sparkles and dramatic god rays
- − The fox's anatomy looks slightly distorted where it meets the grass
- − The kitten's facial features are slightly less defined than model A
Verdict: While FLUX.1 Krea produced a very clean and adorable image, it failed a key part of the prompt by omitting the baby bunny and adding a second kitten instead. Seedream 4.0 followed the complex multi-subject prompt perfectly, capturing the specific interaction, lighting effects, and all required animal types in a more dynamic composition.
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 Krea [dev]
- + Excellent hand-drawn etching style that fits the vintage aesthetic.
- + Beautiful background texture and distressing.
- + Correctly followed the 'Est. 1720' date requirement.
- − Serious spelling error in the main brand name ('FLANOR'IN' instead of 'Florian').
- − The cloche dome is stylized to the point of looking a bit like a bottle or jar top.
Seedream 4.0
- + Perfect text rendering for 'Caffè Florian' including the accent mark.
- + Clean, vector-style layout that is very legible.
- + Stronger adherence to the 'minimalist' part of the prompt.
- − The 'Est. 1720' banner is slightly less integrated into the total emblem compared to Model A.
- − The steam effect is a bit generic and flat.
Verdict: Seedream 4.0 is the clear winner because it correctly spelled the requested brand name 'Caffè Florian', whereas FLUX.1 Krea [dev] failed significantly on the typography. While FLUX.1 Krea [dev] offered a more sophisticated artistic texture, Seedream 4.0 provided a superior functional logo with a clean layout and perfect prompt adherence.
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 Krea [dev]
- + Features a bold, clean heading and modern typography.
- + Captures a cohesive dark-space aesthetic with a consistent color palette.
- − Failed to provide several requested icons, replacing the Saturn V and Lunar Module with astronauts and a generic planet.
- − The layout is confusing with non-sequential numbering and nonsensical arrows.
Seedream 4.0
- + Followed the specific icon requests for all 6 steps, including the Saturn V, orbit rings, and Lunar Module.
- + Displays a clear, logical infographic flow with legible text labels for each stage.
- + Successfully incorporated the astronaut names and 'Tranquility' location marker requested in the trailing prompt instructions.
- − The 'Landing 6' text is disproportionately large compared to other steps.
- − Minor spelling errors in labels such as 'Surface' and slight artifacts on the Lunar Module legs.
Verdict: Seedream 4.0 is the clear winner because it followed the complex instructional logic of the prompt, creating specific icons for each phase of the mission from launch to landing. In contrast, FLUX.1 Krea produced a disjointed image that ignored the requested icon types and failed to maintain a logical sequence.
