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 Kontext [max]
- + Excellent handling of caustics and light refraction through the glass cube.
- + High level of texture detail on the book cover and the glittery blue sphere.
- + Realistic shadows and lighting direction.
- − The plant is positioned to the side rather than directly behind the cube as requested.
- − The glass cube appears to have a thick base that gives it a container-like look rather than a simple geometric cube.
Seedream 4.0
- + Perfectly adheres to the spatial prompt with the plant situated directly behind the cube.
- + Clean, minimalist composition that clearly displays all requested elements.
- + Accurate representation of a simple glass cube.
- − The textures are noticeably softer and less detailed than Image A.
- − The lighting on the blue sphere feels slightly disconnected from the environment.
Verdict: While FLUX.1 Kontext [max] produces a significantly more detailed and photorealistic image with impressive light physics, Seedream 4.0 followed the spatial instructions more accurately by placing the plant behind the cube. FLUX.1 Kontext [max] is the preferred choice for visual quality, though Seedream 4.0 is better for precise object placement.
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 Kontext [max]
- + Exceptional skin texture and anatomical detail in the hands.
- + Beautifully rendered rain effects and complex reflections on the wet asphalt.
- + Cinematic lighting that perfectly matches the 50mm lens look requested.
- − The bike geometry is nonsensical, with some parts of the frame appearing to pass through others.
- − The rain streaks are a bit too uniform across the foreground and background.
Seedream 4.0
- + Excellent adherence to the motion blur request with the passing car.
- + Very believable environmental storytelling with the tools on the ground.
- + Accurate bike anatomy and a more 'candid' feel to the composition.
- − Noticeable AI artifacts on the man's hands and face, which appear slightly soft.
- − The puddle reflection is missing the man's upper body and the bike's front wheel, making it look inconsistent.
Verdict: Both models followed the prompt well, but FLUX.1 Kontext [max] produced a much higher quality image in terms of texture, lighting, and mood, looking like a professional photograph despite some structural errors in the bicycle. Seedream 4.0 captures the specific elements of the prompt better (the motion blur and candid tools), but falls behind on technical image quality and realistic human features.
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 Kontext [max]
- + Exceptional intricate engraving detail on the plate armor
- + Highly realistic skin texture with visible pores and sweat
- + Lifelike eye details with complex amber iris patterns
- − Missed the request for beads in the hair braids
- − The skin tone appears overly saturated or orange under the lighting
Seedream 4.0
- + Perfect adherence to the hair beads prompt
- + Excellent representation of 'battle-worn' via realistic dirt and scars
- + Stronger composition with a clear torch source and warm bokeh
- − Leather strap buckles appear slightly warped or anatomically incorrect
- − Armor engravings are less sharp and detailed compared to the competitor
Verdict: Seedream 4.0 followed the specific prompt details more closely, particularly by including the requested beads in the braids and providing a more convincing 'battle-worn' appearance with dirt and scars. While FLUX.1 Kontext [max] has superior texture resolution on the metal and skin, Seedream 4.0's better lighting composition and adherence to all stylistic elements make it the more successful image for this prompt.
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 Kontext [max]
- + Excellent professional layout that looks like a real menu.
- + Clean grid structure with consistent food photography.
- + Includes realistic price headers and decorative typography.
- − Text consists of gibberish words and characters.
- − Sections are not clearly labeled for 'Appetizers' or 'Mains' as requested.
Seedream 4.0
- + Legible rendering of the requested headers (Appetizers, Pizza, Mains).
- + High-quality, vibrant food photography.
- + Bold sans-serif font matches the prompt requirements.
- − Poor composition that feels more like a mood board than a restaurant menu.
- − Lack of pricing, descriptions, or menu structure.
- − Layout is cluttered and lacks white space.
Verdict: FLUX.1 Kontext [max] produces a much more convincing menu design with a professional grid and realistic formatting, though the text content is unintelligible. Seedream 4.0 follows the text prompts for specific section headers much better, but fails to create a functional or aesthetically pleasing menu layout, resulting in a disorganized collage. FLUX.1 Kontext [max] is preferred for its superior understanding of graphic design and layout conventions.
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 Kontext [max]
- + Excellent typography with clean, consistent 'Magic Burger' lettering.
- + Highly photorealistic textures on the bun and patty.
- + Perfectly accurate pricing at €6.99.
- − The burger is not truly 'exploded'; most of it is still stacked in the center.
- − The starburst for the price is very small and lacks impact.
Seedream 4.0
- + Dynamic 'exploded' composition with a strong sense of motion/swirl.
- + Excellent integration of the fiery text effect for the main title.
- + Clear and prominent starburst for the price.
- − The price is incorrect at €5.99 instead of €6.99.
- − The burger layers look slightly disorganized and messy compared to Model A.
- − The 'LIMITED TIME ONLY' text is slightly less polished in its lighting.
Verdict: FLUX.1 Kontext [max] delivers a more polished, professional-looking advertisement with perfect text accuracy and realistic food textures, though it fails to create a truly 'exploded' burger. Seedream 4.0 captures the 'exploded' and 'dynamic' motion requested much better, but it fails the specific requirement for the price value. FLUX.1 Kontext [max] is the preferred choice for a commercial asset due to its superior clarity and adherence to the numerical data.
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 Kontext [max]
- + Excellent text legibility and alignment
- + Accurately completed the partial prompt regarding the last menu item
- + Very clean, professional composition with realistic chalk smudges
- − The title is in print-style handwriting rather than the requested 'elegant cursive'
Seedream 4.0
- + Successfully applied an elegant cursive style to the title
- + Exceptional chalk texture and realistic dusty chalkboard finish
- + Great use of depth of field to create a cozy café atmosphere
- − The text is slightly harder to read due to the heavy chalk smudging
- − The handwriting style is less consistent between the title and the list items
Verdict: Both models followed the prompt's text requirements exceptionally well. FLUX.1 Kontext [max] produced a cleaner, more legible image that correctly inferred the final menu item, whereas Seedream 4.0 captured the 'elegant cursive' requirement and the specific atmospheric texture of a dusty chalkboard much better.
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 Kontext [max]
- + Excellent anatomical details, especially in the horse's musculature and the astronaut's suit stitching.
- + Perfectly balanced composition with a clean, cinematic depth of field.
- + Great lighting coherence where the light catch on the horse's coat reflects the distant planet.
- − The mane and tail physics look slightly more static compared to the action in Model B.
Seedream 4.0
- + Dynamic, energetic posing with the horse rearing up.
- + Vibrant and colorful nebulas in the background add to the surreal feel.
- + Creative reflection of a galaxy inside the astronaut's visor.
- − Low visual quality with noticeable blurring on the horse's legs and background.
- − Compositional issues where parts of the horse and astronaut are cut off by the frame.
- − The horse's front legs exhibit some warping artifacts.
Verdict: While both models followed the prompt correctly, FLUX.1 Kontext [max] is the clear winner due to its significantly higher resolution and anatomical precision. Seedream 4.0 captures a more dynamic pose and vibrant colors, but suffers from low-quality textures and poor framing where the subjects are awkwardy cropped.
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 Kontext [max]
- + Excellent photorealism with high-quality textures on the capybara's fur and the leather hat
- + Effective cinematic lighting and shallow depth of field reflecting a Manhattan night
- + Clean, accurate text rendering on the driver's cap
- − The passenger is holding the phone to her ear like a call rather than looking at it as requested
- − One of the front paws is partially merged or poorly defined against the steering wheel
Seedream 4.0
- + Perfect adherence to the passenger's action, showing her looking down at the phone with a bored expression
- + Strong composition that clearly shows the interior layout of the taxi and both characters
- + Accurate placement of both paws on the steering wheel
- − Text on the driver's cap is garbled ('TAT' instead of 'TAXI')
- − Slightly lower fidelity in the capybara's fur texture compared to the other model
Verdict: FLUX.1 Kontext [max] produces a more photorealistic image with superior textures and lighting, but it fails the specific prompt instruction regarding the passenger's interaction with her phone. Seedream 4.0 captures the mundane, bored atmosphere of the passenger much better and follows the physical placement of the capybara's paws more accurately, despite the garbled text on the hat. Seedream 4.0 is the winner for better prompt adherence and storytelling, while FLUX.1 Kontext [max] is visually more impressive.
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 Kontext [max]
- + Excellent typographic layout and readability
- + Perfect spelling of all required text elements
- + Clean and professional graphic design aesthetic
- − The date follows a non-standard comma format (30.10.2026 vs 30,10,2026)
- − The banner for the sub-text is a simple ribbon rather than a traditional scroll
Seedream 4.0
- + Atmospheric cinematic lighting on the jack-o-lantern
- + Stronger 'vintage parchment' texture with burnt edges
- + Creative use of layered thorns and webs in the border
- − Text on the banner is garbled and barely legible
- − Layout feels a bit cluttered with the thorns overlapping the design
- − The tree silhouettes are somewhat blurry compared to the foreground
Verdict: FLUX.1 Kontext [max] follows the prompt instructions perfectly, delivering crisp, professional typography and all requested text without errors. While Seedream 4.0 has a more immersive and atmospheric cinematic style, it fails significantly on the text legibility of the scroll banner.
Bald man challenge
Image Editing“Give the person a full, thick head of natural hair with realistic texture, density, and a natural hairline. Preserve facial features and lighting.”
AI Judge Analysis
FLUX.1 Kontext [max]
- + Excellent texture and realistic hair flow
- + Better preservation of facial detail and lighting
- + Matches the thickness and color of the existing beard well
- − Slightly altered the shape of the glasses frame
- − Minor distortion on the ear-to-hair transition
Seedream 4.0
- + Good volume and density as requested
- + Preserves the glasses and facial features very accurately
- − Hair texture looks slightly fuzzy or synthetic compared to the beard
- − The hairline/forehead transition is less realistic and lacks fine detail
Verdict: FLUX.1 Kontext [max] provides a much more convincing and natural hair texture specifically regarding the way the light interacts with individual strands, whereas Seedream 4.0 has a slightly blurred, unnatural quality to the new hair. While Seedream 4.0 did a better job of not touching the glasses, FLUX.1 Kontext [max] is the overall winner for the high quality and realism of the hair itself.
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 Kontext [max]
- + Excellent 3D cartoon style with soft, appealing textures
- + Clean typography that matches the aesthetic of the scene
- + Accurate 45-degree isometric projection and lighting
- − Failed to include the small flag icon requested in the prompt
- − The nigiri fish texture is slightly stylized/flat compared to the rice
Seedream 4.0
- + Successfully included the requested small flag icon next to the text
- + High variety of sushi types adding visual interest
- + Good material detail on the rice and roe
- − The text is slightly off-center and the layout feels more crowded
- − The 'gentle lighting' is a bit harsh with strong shadows compared to the soft-light request
Verdict: FLUX.1 Kontext [max] delivered a more cohesive 'cartoon' aesthetic with superior typography and a cleaner diorama layout, though it missed the flag icon. Seedream 4.0 followed the specific detail instructions better by including the flag and more sushi varieties, but the overall composition and lighting were less refined than the first model.
Over-the-top cartoon caricature
Editing“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.”
AI Judge Analysis
FLUX.1 Kontext [max]
- + Excellent caricature style with clean, vibrant line art.
- + Successfully incorporates all elements: tv anchor desk, dog, and hockey stick.
- + Maintains character likeness while translating it into a cartoon aesthetic.
- − The hockey element is less integrated, appearing as just a stick tip in the corner.
- − Adds glasses which were not in the original photo.
Seedream 4.0
- + Cleverly integrates hockey by putting the subject in a team jersey and including a stick and jersey on the desk/set.
- + Retains the realistic background and textures from the source image while exaggerating the face.
- + Shows high creativity by combining the 'selfie' pose of the original with the anchor desk.
- − The dog's placement and lighting look slightly disconnected from the rest of the scene.
- − The hands and phone have some minor anatomical distortions typical of AI.
Verdict: Both models did an excellent job of following complex instructions. FLUX.1 Kontext [max] opted for a full 2D cartoon caricature style which is very visually appealing, while Seedream 4.0 created a 3D-style caricature that preserved more of the original source image's environment and successfully infused hockey into the character's clothing. Seedream 4.0 is the winner for better integration of all three themes (TV, dogs, hockey) into a single cohesive 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 Kontext [max]
- + Excellent character consistency and alignment of all four requested species
- + Beautiful soft lighting and color palette that feels very warm and wholesome
- + High technical clarity in the fur texture and eye details
- − The composition is a bit static with the animals sitting in a row rather than playfully tumbling
- − The god rays look a bit artificial with added star-sparkle effects
Seedream 4.0
- + Superb captures of motion and playfulness as requested in the 'tumbling' prompt
- + Very realistic dew/water droplets and complex backlighting
- + Dynamic composition with animals interacting in 3D space
- − The kitten has five legs or a very confusing anatomical structure in its lower body
- − The fox's anatomy is slightly warped in the midsection during its roll
Verdict: FLUX.1 Kontext produced a much cleaner and more stable image with perfect species representation, but it lacked the 'tumbling' and 'chasing' action requested. Seedream 4.0 captured the spirit of the prompt's action and lighting beautifully but suffered from significant anatomical artifacts on the kitten and fox.
Studio Ghibli Anime Style
Editing“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”
AI Judge Analysis
FLUX.1 Kontext [max]
- + Excellent preservation of the source image's composition and background details.
- + Accurately replicates the specific clothing patterns, such as the plaid shirt.
- + Captures the 'distracted boyfriend' meme expressions perfectly in an anime style.
- − The aesthetic leans more toward modern 90s-style anime than the soft, painterly Ghibli look.
- − Shadows and lines are slightly too sharp for a 'hand-painted' texture.
Seedream 4.0
- + Stronger adherence to the 'hand-painted' watercolor texture requested.
- + Colors are softer and more nostalgic, aligning well with the Studio Ghibli prompt.
- + Successfully simplifies the backgrounds to a dreamy, atmospheric style.
- − Loses significant spatial context by replacing the city street with abstract colorful clouds.
- − The character expressions are much more muted and don't convey the specific 'memetic' emotions as clearly as the source.
Verdict: FLUX.1 Kontext [max] is the winner for its incredible ability to preserve the original image's context, clothing details, and character expressions while perfectly translating them into an anime style. While Seedream 4.0 captures the soft watercolor texture of Studio Ghibli more accurately, it loses the specific urban setting of the original meme, making it feel less like an edit and more like a loose reinterpretation.
Golden Hour Stroll
Image Editing“Add dynamic motion to this photo: make hair blow in the wind, add leaves flying, energetic and lively feel.”
AI Judge Analysis
FLUX.1 Kontext [max]
- + Excellent preservation of the woman's face and original features.
- + Highly realistic hair physics showing wind direction.
- + The added hand gesture touching the dog feels natural and adds to the 'lively' feel.
- − The dog's tail is slightly altered compared to the source.
- − Change in body posture and hand position deviates from the source image conservation.
Seedream 4.0
- + Successfully added high-energy flying leaves with a motion blur effect.
- + Very strong adherence to the prompt's request for 'energetic and lively' feel.
- + Maintains the central pose and posture of the woman and dog nearly perfectly.
- − Significant distortion of the woman's face, losing the original likeness.
- − Introduced a harsh artificial sun flare in the top right that was not requested.
- − The leaves have a lower resolution/painterly texture that clashes with the photographic background.
Verdict: FLUX.1 Kontext [max] produced a much higher quality edit by keeping the woman's face intact and making the wind effect in the hair look photorealistic, even though it changed her arm position. Seedream 4.0 followed the 'flying leaves' instruction more aggressively and maintained the pose better, but distorted the subject's face and added unwanted artifacts like the sun flare. FLUX.1 Kontext [max] is the winner for its superior visual quality and technical execution of the hair movement.
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 Kontext [max]
- + Excellent typography with proper accented characters
- + Consistent woodcut-style texture that feels authentically vintage
- + Perfect execution of the 'Est. 1720' banner
- − Minimal steam detail above the cloche
Seedream 4.0
- + Dynamic arched text layout
- + Good use of shadows and highlights on the cloche dome
- + Authentic paper-like background texture
- − The accent mark on 'Caffé' is misplaced or stylistically inconsistent
- − The banner folding logic is a bit distorted on the left side
Verdict: FLUX.1 Kontext [max] produced a superior professional logo with cleaner typography and a more cohesive 'vintage minimalist' aesthetic. Seedream 4.0 has great shading and color depth but struggles with the finer details of the banner and the specific typography requested.
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 Kontext [max]
- + Excellent typography and clean, modern vector aesthetic.
- + High-quality, detailed icons for the Lunar Module and Saturn V.
- + Sophisticated, professional layout with a coherent NASA-inspired color scheme.
- − Confused the logical order of the infographic steps.
- − Missed several text labels requested in the prompt.
- − Included some garbled placeholder text near the moon.
Seedream 4.0
- + Strictly followed the requested 1-6 step progression in the correct order.
- + Accurately rendered text labels for more of the mission stages.
- + Good use of iconography for Earth orbit and trajectory arcs.
- − Visual style feels a bit more like clip-art rather than a professional poster.
- − The 'Landing 6' text is disproportionately large and dominates the layout.
- − Minor spelling error in the text ('Surfcce').
Verdict: While FLUX.1 Kontext [max] produces a much more visually stunning and professional-looking poster, it fails the basic information design challenge by scrambling the mission steps. Seedream 4.0 successfully follows the requested 6-step structure and includes more specific labels from the prompt, making it more functional as an infographic despite its less refined artistic style.
