Man and Car in California
Editing“Make a photo of the man driving the car down the California coastline”
AI Judge Analysis
FLUX.2 [max]
- + Perfect preservation of the car's model and specific details
- + Excellent character consistency including the specific plaid pattern of the coat
- + High resolution with sharp details on the background scenery
- − The man is positioned as a passenger rather than the driver (left-hand drive car)
Seedream 4.0
- + Correctly places the man in the driver's seat
- + Good adherence to the requested motion/driving theme
- + Maintains identifiable features of both the car and the man
- − Noticeable loss of detail on the car's grille and headlights
- − Visible artifacts and blurring in the background
- − Anatomy issues with the driver's left hand and steering wheel connection
Verdict: FLUX.2 [max] produces a significantly higher quality image that perfectly preserves the textures and details of the source car and the man's outfit, though it fails the instruction to make him the 'driver' by placing him on the right side of a left-hand drive car. Seedream 4.0 follows the 'driver' instruction better but suffers from lower resolution, warped geometry on the car's front end, and messy rendering of the steering wheel and hands.
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.2 [max]
- + Excellent photorealism with realistic textures for the book cover and wood grain.
- + Superior lighting effects, including soft shadows and a convincing mirror-like reflection at the base of the cube.
- + Clean, modern composition with a shallow depth of field that highlights the subject.
- − The plant in the background is quite blurry, making 'partially visible through the glass' less distinct.
Seedream 4.0
- + Follows the prompt instructions for spatial relationships accurately.
- + The plant is clearly visible through the glass as requested.
- + Realistic sunlight patterns on the wooden table surface.
- − The glass cube has slightly messy edges/corners with some visual artifacts.
- − The lighting on the blue sphere looks a bit flat compared to the rest of the scene.
Verdict: Both models followed the prompt perfectly. FLUX.2 [max] produced a much higher quality, more polished image with professional-grade textures and lighting. Seedream 4.0 performed well and captured the transparency of the glass accurately, but it lacked the fine detail and realism seen in FLUX.2 [max].
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.2 [max]
- + Strict adherence to a functional menu layout including pricing and descriptions.
- + Excellent text rendering with clean sans-serif fonts.
- + Well-organized grid of food items that complements the text sections.
- − Some food labels don't perfectly match the photos (e.g., 'Pizza' section lists items that look like wraps or sandwiches).
- − Minor gibberish in the smaller descriptive text.
Seedream 4.0
- + High-quality, vibrant food photography.
- + Bold, clear text for category headers.
- − Failed to create a functional menu; it is just a collage of photos and headers.
- − Missing actual menu items, prices, and descriptions requested in the prompt.
- − Composition is unbalanced with significant white space and overlapping elements.
Verdict: FLUX.2 [max] significantly outperformed Seedream 4.0 by creating a complete, professional menu layout with headers, item descriptions, and prices. While Seedream 4.0 produced high-quality food photography, it failed to provide the 'menu design' aspect, acting more as a simple image collage. FLUX.2 [max] followed the prompt's structural requirements for a casual dining layout 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.2 [max]
- + Excellent skin texture and realistic age details on the face and hands.
- + Strong cinematic lighting with accurate bokeh and rain drops on the jacket.
- + Perfect adherence to the 50mm lens and shallow depth of field request.
- − The 'motion blur from passing cars' is minimal, as the car appears nearly stationary.
- − A strange floating cable/artifact is visible near the man's mouth.
Seedream 4.0
- + Stronger execution of the requested motion blur on the passing vehicle.
- + Includes repair tools on the ground which enhances the narrative.
- + Clear, high-contrast reflections on the wet pavement.
- − Anatomical issues with the hands, which look merged and messy.
- − The bicycle's geometry is nonsensical, especially the frame/pedal connection.
- − The overall image quality is softer and looks more like a digital painting than a 50mm photo.
Verdict: FLUX.2 [max] captures a much more realistic and cinematic scene with high-fidelity skin textures and believable lighting, though it slightly misses the motion blur intensity. Seedream 4.0 does a better job with the motion blur and environmental details like tools, but fails significantly on the anatomy of the hands and the structural logic of the bicycle. FLUX.2 [max] is the clear winner for its superior photographic quality and realism.
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.2 [max]
- + Natural-looking hair texture and volume.
- + Realistic graying hair on the sides that matches the existing beard.
- + Maintains excellent facial structure preservation.
- − Inadvertently lightened the color of the beard chin area.
- − Slightly changed the shape of the glasses frame on the left side.
Seedream 4.0
- + Successfully added a large volume of hair.
- + Preserves the original beard color and texture perfectly.
- − Hair looks like a wig or a 'helmet' due to the uniform texture.
- − The hairline is unnaturally straight and high, looking pasted on.
- − Slightly softened the skin texture compared to the original.
Verdict: FLUX.2 [max] provides a much more convincing result with realistic hair texture and a believable hairline that integrates with the existing beard, despite some minor shifts in beard color. Seedream 4.0 creates an Uncanny Valley effect where the hair looks like a physical prop rather than a natural part of the person.
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.2 [max]
- + Excellent adherence to the isometric perspective and diorama base request.
- + Crisp and accurate text rendering with a clean layout.
- + High-quality 3D rendered aesthetic with soft, professional lighting.
- − The sushi models are a bit simplified/stylized compared to the 'refined textures' request.
Seedream 4.0
- + Beautifully detailed textures on the fish and rice grains.
- + Vibrant colors and appealing food presentation.
- + Correct text and flag inclusion.
- − Perspective is more of a standard 3/4 view rather than a true 45-degree isometric angle.
- − Lacks the specific 'small raised diorama base' (it uses a standard plate/mat).
Verdict: FLUX.2 [max] followed the spatial and compositional instructions much better, delivering a true isometric diorama with a clear 45-degree top-down feel. While Seedream 4.0 had superior texture work on the sushi itself, it failed to capture the requested isometric miniature aesthetic and diorama base as effectively as FLUX.2 [max].
Adorable Baby Animals in Sunny Meadow
Text-to-Image“Hyper-photorealistic scene of fluffy baby animals—a golden retriever puppy, tabby kitten, baby bunny, and red fox kit—with big expressive eyes and ultra-detailed soft fur, playfully chasing butterflies and tumbling together in a lush wildflower meadow, warm golden sunrise light with god rays and dew sparkles, joyful wholesome vibe, 8K masterpiece.”
AI Judge Analysis
FLUX.2 [max]
- + Excellent anatomical accuracy for all four animals, particularly the fox and rabbit.
- + Highly realistic lighting and depth of field with subtle dew sparkles.
- + Superior fur texture and fine whisker details that look photorealistic.
- − The composition is a bit linear, with the animals mostly standing in a row.
- − The butterflies are somewhat small and less expressive than requested.
Seedream 4.0
- + Dynamic and playful composition that perfectly captures the 'tumbling' and 'chasing' aspect of the prompt.
- + Beautifully emphasized god rays and intense golden hour atmosphere.
- + Very expressive 'big eyes' on the animals as requested.
- − Anatomical issues including the kitten having five legs and a strange tail attachment.
- − The fox kit looks more like a red panda/fox hybrid with slightly oversaturated colors.
- − Significant floating artifacts and unrealistic water/light spots that look like glitches rather than dew.
Verdict: FLUX.2 [max] produces a significantly more coherent and realistic image with technically perfect anatomy and subtle, high-quality lighting. While Seedream 4.0 captures the playful energy and 'tumbling' motion of the prompt much better, it suffers from major anatomical errors (extra kitten limbs) and messy artifacts. FLUX.2 [max] is the winner for its professional polish and photorealistic execution despite the slightly safer composition.
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.2 [max]
- + Successfully incorporates all themes including TV anchor, hockey, and dogs.
- + Strong, clean illustration style that feels intentionally artist-driven.
- + Creative and humorous set design with dogs as co-anchors.
- − Loses the photographic likeness and shifts entirely to a vector art style.
- − The character's face is a generic cartoon representation rather than a caricature of the specific person.
Seedream 4.0
- + Excellent caricature of the person's face, maintaining recognizable features while exaggerating them.
- + Preserves the photographic nature and background of the original image while seamlessly adding new elements.
- + Cleverly blends the denim outfit from the original into a custom hockey-themed anchor ensemble.
- − The hand holding the phone is a bit small and anatomically awkward.
- − The dog is a bit static compared to the high energy of the caricature.
Verdict: Seedream 4.0 is the clear winner as it performs an actual caricature edit, maintaining the subject's likeness while exaggerating her features in a humorous way. FLUX.2 [max] creates a high-quality illustration, but it completely discards the source image's likeness in favor of a generic cartoon character, failing the primary goal of the prompt to create a caricature of 'me'.
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.2 [max]
- + Excellent character likeness and facial expressions preserved from the source.
- + Perfectly captures the Studio Ghibli cel-shaded aesthetic with pencil-like line work.
- + Strong adherence to original composition and clothing details.
- − Texture is a bit heavy on the 'aged paper' grain rather than just paint.
Seedream 4.0
- + Beautiful hand-painted watercolor textures that feel very organic.
- + Successful use of soft pastel colors and a dreamy background.
- + Maintains the core composition of the meme perfectly.
- − Faces are simplified too much, losing the specific expressions/likeness of the original people.
- − Line work is a bit inconsistent in some areas compared to the background texture.
Verdict: Both models did an excellent job transforming the iconic 'Distracted Boyfriend' meme into the requested style. FLUX.1 [max] is the winner because it successfully balances the Studio Ghibli aesthetic with the original actors' facial expressions, which are crucial to the context of the image. While Seedream 4.0 has superior watercolor textures, its character faces are a bit too generic and lose the 'humor' of the source image's expressions.
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.2 [max]
- + Excellent prompt adherence with clear wind-blown hair and numerous flying leaves.
- + Maintains high resolution and sharp detail across the entire image.
- + Preserves the original facial features and clothing details perfectly.
Seedream 4.0
- + Effectively communicates motion through hair styling and flying leaves.
- + Adds a subtle motion blur to some leaves which enhances the sense of movement.
- − Noticeable drop in overall image sharpness and resolution compared to the source.
- − Slightly Alters the woman's facial features and eyes, making them look less natural.
- − Leaves appear somewhat flat and less integrated into the lighting of the scene.
Verdict: FLUX.2 [max] is the clear winner as it successfully adds the requested dynamic elements while perfectly preserving the high resolution and facial integrity of the source image. In contrast, Seedream 4.0 significantly degrades the image quality, resulting in a blurrier output and unnecessary changes to the subject's face.
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.2 [max]
- + Perfectly captures the requested 'vector emblem' style with clean linework
- + Exceptional typography with accurate accents and elegant curvature
- + Subtle but effective paper texture that feels authentic to a vintage brand
- − The steam lines are very thin compared to the rest of the logo's weight
Seedream 4.0
- + Stronger contrast and bolder colors give it high visual impact
- + Accurate text rendering for both the name and the banner date
- + Good use of shadows to give the cloche depth
- − Lines are slightly more jagged/pixelated, appearing less like a clean vector
- − The steam effect looks a bit heavy and detached from the cloche handle
Verdict: FLUX.2 [max] produced a superior result that perfectly embodies the 'vector emblem' and 'minimalist' keywords, featuring clean professional-grade linework and perfect typography. While Seedream 4.0 followed all instructions correctly, its execution feels more like a raster illustration than a polished logo, with slightly less refined edges on the text and graphics.
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.2 [max]
- + Excellent typography and spelling throughout the poster.
- + Clean, professional grid layout that mimics a real infographic.
- + Consistent and high-quality vector iconography.
- − The sequence of steps is out of order (e.g., Translunar comes after Lunar Orbit).
- − The 'Translunar' icon incorrectly shows a Moon instead of a trajectory/arc.
Seedream 4.0
- + Follows the logical chronological order of the mission steps (1 through 6).
- + Effective use of the requested NASA-inspired color palette.
- + Good use of arrows to indicate movement and progression.
- − The descent and landing steps share a single, somewhat messy illustration.
- − Text rendering is inconsistent with some overlapping characters and typos ('Tranquiilty').
- − The icons are less 'crisp' and modern than the competitor's.
Verdict: FLUX.2 [max] creates a much more aesthetically pleasing and professional-looking poster with superior typography, though it fails on the logic of the mission sequence. Seedream 4.0 correctly orders the steps but suffers from lower-quality graphics and several spelling/layout errors. FLUX.2 [max] is the preferred choice for its visual fidelity and clean execution of the 'modern vector' style.
