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
Seedream 4.0
- + High-quality, appetizing food photography
- + Clean typography and bold headers
- + Good white space balance for a minimalist look
- − Lack of actual menu content like descriptions or prices
- − The layout is more of a collage than a functional menu design
Seedream 5.0 Lite
- + Excellent adherence to the 'menu design' prompt including pricing and item names
- + Strong typographic hierarchy with vibrant color-coding for sections
- + Perfect text rendering without any spelling errors
- − The food photography looks slightly more artificial/stock-like compared to Model A
Verdict: Seedream 5.0 Lite is the clear winner as it creates a fully functional, professional menu design with accurate text, pricing, and organized sections. Seedream 4.0 produces beautiful photography but fails to provide the structure of an actual menu, resulting in more of a Pinterest-style mood board.
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
Seedream 4.0
- + Excellent handling of complex reflections and refractions on the glass and wooden table.
- + Highly realistic lighting and textures, especially on the red book and marble-like sphere.
- + Superior rendering of 'partially visible' green plant through the glass volume.
- − The glass cube has a visible floor/baseplate inside it that wasn't explicitly requested, though it adds to the realism.
Seedream 5.0 Lite
- + Perfect adherence to all spatial instructions in the prompt.
- + Clean, bright composition with soft window lighting.
- + Good texture on the book cover and wooden table.
- − The glass refraction is less realistic, as the plant visible through the glass doesn't distort naturally compared to the part above it.
- − The blue sphere has a very matte, flat appearance compared to the rest of the scene.
Verdict: Both models followed the prompt perfectly. Seedream 4.0 is the winner due to its superior handling of physics; the reflections on the table and the realistic distortion of the plant through the glass make for a much more convincing photograph. Seedream 5.0 Lite is very clean but feels more like a 3D render with slightly inconsistent refractions.
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
Seedream 4.0
- + Excellent adherence to 'motion blur from passing cars' through the blurred vehicle in the background.
- + Strong overall composition with visible tools and a full-body view that feels natural.
- + Good reflection on the wet pavement which adds to the rainy atmosphere.
- − Anatomical issues with the man's hands, which appear distorted.
- − Technical glitches in the bicycle geometry, particularly the rear wheel spokes and frame junctions.
Seedream 5.0 Lite
- + Superior photographic quality with very realistic skin texture and hair detail.
- + Excellent rendering of hands and delicate interaction with the bicycle chain.
- + Effective use of lighting and 'bokeh' to create a cinematic atmosphere.
- − The 'motion blur from passing cars' is less distinct than in Model A.
- − Closer cropping misses some of the environmental storytelling like the tools on the ground.
Verdict: Seedream 5.0 Lite produces a much more realistic and high-quality image, particularly in the rendering of the man's face and hands which are often difficult for AI. While Seedream 4.0 followed the specific request for motion-blurred cars more literally, Seedream 5.0 Lite's overall visual fidelity and lack of structural artifacts on the bicycle make it the superior choice.
Man and Car in California
Editing“Make a photo of the man driving the car down the California coastline”
AI judge analysis unavailable for this challenge.
Bald man challenge
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
Seedream 4.0
- + Perfectly preserves facial features, lighting, and background
- + Adds extremely thick hair as requested
- + Matches the hair color beautifully to the beard
- − The hairline is overly rectangular and looks slightly unnatural
- − The hair volume is arguably too high, creating a 'wig' effect
Seedream 5.0 Lite
- + Provides a very realistic, natural-looking hairline
- + The hair texture and style are extremely convincing and well-integrated
- + Excellent preservation of the original image identity
- − The hair is slightly less 'thick/full' compared to the other model, though more realistic
Verdict: Both models did an excellent job of preserving the source image while adding hair. Seedream 4.0 followed the 'thick' instruction more literally but resulted in a somewhat stiff, rectangular hairline. Seedream 5.0 Lite produced a far more realistic result with a natural hairline and more believable hair density that blends perfectly with the existing facial hair.
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
Seedream 4.0
- + Excellent texture work on the salmon and rice grains.
- + Beautiful lighting and soft shadows that give it a premium 3D look.
- + Clear and legible text with a clean flag icon.
- − The 'diorama base' is just a plate, lacking the raised platform feel requested.
- − The flag icon is slightly misaligned horizontally with the text.
Seedream 5.0 Lite
- + Perfect adherence to the 'raised diorama base' and '45° isometric' prompt instructions.
- + Very clean, minimalist aesthetic with high clarity.
- + Large, bold, and stylized typography with a high-quality 3D flag icon.
- − Sushi textures are slightly more 'plastic' and less detailed than in the other model.
- − The food is scaled a bit small relative to the base and the text.
Verdict: Seedream 5.0 Lite followed the spatial instructions more accurately, providing a distinct raised diorama base and a perfect isometric perspective. While Seedream 4.0 had superior food textures and more realistic lighting on the sushi itself, Seedream 5.0 Lite produced a cleaner, better-composed scene that feels more like a miniature 3D diorama/icon.
Night Sky Transformation
Editing“Change the scene to night: a deep, dark sky with subtle, glistening stars visible behind the mountain.”
AI Judge Analysis
Seedream 4.0
- + Successfully converts the sky to a night scene with stars.
- + Excellent preservation of the foreground village and landscape structure.
- − The number of stars is relatively sparse compared to the 'subtle, glistening' request.
- − A slight loss of contrast in the mountain's snow compared to the original.
Seedream 5.0 Lite
- + Perfectly captures 'subtle, glistening stars' with better density and variety.
- + Maintains higher clarity and sharper details on the mountain peak.
- + Excellent preservation of the original image's composition and lighting in the town.
- − One or two stars appear slightly like digital artifacts near the peak tip.
Verdict: Both models did an exceptional job of preserving the source image while applying the night sky edit. Seedream 5.0 Lite wins by a narrow margin because its star rendering is more aesthetically pleasing and more accurately reflects the 'glistening' instruction, while maintaining better sharpness on the Matterhorn's textures.
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
Seedream 4.0
- + Excellent preservation of the source subject's facial features even in caricature form.
- + Cleverly integrates hockey elements into the clothing and set pieces.
- + Maintains the background elements from the source image like the framed pictures and sofa.
- − The anatomy of the right hand holding the phone is distorted.
- − The transition between the desk and the background feels slightly cluttered.
Seedream 5.0 Lite
- + Clear and clean 'cartoon' style illustration with bold lines.
- + Accurately includes all requested elements: anchor desk, hockey stick, puck, and dog.
- + Excellent text rendering on the nameplate.
- − Completely replaces the background and source image style instead of editing it.
- − The character design is a generic cartoon style that loses much of the source person's likeness.
Verdict: Seedream 4.0 is the superior choice for this specific editing task because it successfully transforms the source image into a caricature while maintaining the original person's specific facial features and the original background environment. Seedream 5.0 Lite produces a very high-quality illustration, but it ignores the source image's context and replaces the subject with a generic cartoon character, failing the primary goal of editing the existing photo.
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
Seedream 4.0
- + Excellent adherence to lighting requests with clear god rays and realistic dew sparkles.
- + High level of detail in the textures of the fur and delicate rendering of the wildflowers.
- + Dynamic central composition that captures the 'tumbling' and 'playful' aspect of the prompt.
- − The fox's anatomy is a bit awkward where it meets the ground.
- − Some chaotic secondary sparkles/artifacts that look like floating water droplets rather than dew.
Seedream 5.0 Lite
- + Captures a very whimsical, storybook character aesthetic with large expressive eyes.
- + Includes a variety of colorful butterflies as requested.
- + Clean, clear composition where each animal is easily identifiable.
- − Leans more towards a 3D animation/CGI style rather than 'hyper-photorealistic'.
- − The transitions between the animals and the grass are less seamless, looking slightly pasted on.
Verdict: Seedream 4.0 captures the 'hyper-photorealistic' and 'masterpiece' elements of the prompt much better, offering complex lighting and realistic fur textures. Seedream 5.0 Lite produces a charming image, but it resembles a Pixar-style render rather than a photorealistic scene. Seedream 4.0 is the winner for its superior atmospheric effects and tactile detail in the animals and environment.
Victorian Greenhouse Oasis
Text-to-Image“Hyper-photorealistic interior of a lush Victorian glass greenhouse filled with exotic tropical plants, vibrant blooming orchids, tall ferns, colorful butterflies in flight, sunlight filtering through ornate glass roof creating realistic caustics and dew on leaves, intricate iron framework visible, misty atmosphere, 8K masterpiece.”
AI Judge Analysis
Seedream 4.0
- + Captures the misty atmosphere and light rays with high dramatic effect.
- + Excellent rendering of dew drops on the foreground leaves.
- + Intricate ironwork on the glass roof is highly detailed and authentic to the Victorian style.
- − Butterflies look somewhat pasted on and lack motion blur relative to the scene.
- − Composition is a bit cluttered in the foreground with overlapping plants.
Seedream 5.0 Lite
- + Stronger adherence to 'caustics' with realistic light patterns on the floor.
- + Includes a higher variety of plants and more visible butterflies in flight.
- + Better sense of depth and spatial arrangement within the greenhouse.
- − Orchids in the top right appear to be floating or awkwardly attached to the glass.
- − The mist effect is slightly less convincing than in Model A.
Verdict: Both models captured the complex prompt well, but Seedream 4.0 has a slight edge in hyper-photorealism due to superior lighting, mist, and more realistic textures on the foliage. Seedream 5.0 Lite followed the specific instruction for floor caustics better, but some of its botanical placements feel physically illogical compared to the atmospheric coherence of Seedream 4.0.
Heroic Super Hero Portrait
Text-to-Image“Hyper-photorealistic full-body portrait of a female superhero standing triumphantly on a New York skyscraper rooftop at golden sunset, wearing a classic modest superhero costume with flowing cape, chest emblem, gloves, and boots in red and blue colors, practical design, short hair, strong determined heroic expression looking into the distance, powerful confident stance with hands on hips and cape billowing dramatically in the wind, detailed urban cityscape background, warm natural sunlight with sharp shadows and fabric highlights, ultra-sharp textures on suit, hair, and concrete, 8K masterpiece, empowering family-friendly style.”
AI Judge Analysis
Seedream 4.0
- + Excellent fabric texture and suit detailing
- + Realistic skin texture and natural facial features
- + Strong atmospheric lighting that integrates the character into the scene
- − Anatomy issue with the fingers on the right hand
- − Cape attachment to the shoulder looks slightly unnatural
Seedream 5.0 Lite
- + Clean and vibrant color palette
- + Accurate rendering of the hands and fingers
- + Sharp and clear depiction of the New York City skyline
- − The character looks slightly 'pasted' on and lacks depth
- − Suit texture is somewhat flat and rubbery compared to Model A
- − Facial features look a bit more synthetic
Verdict: Both models followed the prompt exceptionally well, delivering a Supergirl-style hero in New York. Seedream 4.0 provides a more cinematic and photorealistic look with superior textures and lighting, despite a minor anatomical flaw in the hands. Seedream 5.0 Lite is cleaner and more anatomically correct, but it feels slightly more like a composite than a single cohesive photograph.

}
AI Judge Analysis
Seedream 4.0
- + Successfully creates a warm Duchenne smile with natural teeth.
- + Preserves the overall head pose and layout well.
- − Softens and smooths the skin texture, losing the distinctive freckles and pores of the original.
- − Slightly Alters the eye shape and iris detail compared to the source.
Seedream 5.0 Lite
- + Excellent preservation of skin texture, freckles, and pores from the source image.
- + More accurate preservation of the subject's specific eye shape and fine details.
- + Subtle and realistic Duchenne smile features (eye crinkles and cheek raise).
- − The transition at the corners of the mouth is slightly blurred compared to the rest of the face.
Verdict: Seedream 5.0 Lite is the clear winner because it follows the preservation instructions much more closely, maintaining the subject's unique skin texture, freckles, and eye details while applying a realistic smile. Seedream 4.0 provides a pleasant result but 'beautifies' the image by smoothing over the skin and changing the eyes, which violated the negative constraints of the prompt.
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
Seedream 4.0
- + Excellent watercolor hand-painted texture
- + Strong adherence to the 'soft pastel colors' and 'dreamy background' instructions
- + Captures the Ghibli aesthetic in a more artistic, nostalgic way
- − Faces are a bit too simplified and look less like the original subjects
- − The man's neck and head connection is slightly awkward
Seedream 5.0 Lite
- + Excellent preservation of the source image's composition and background details
- + Maintains clear character expressions that match the original meme
- + Clean, digital cel-shaded look that is very recognizable as a modern anime style
- − Lacks the 'hand-painted textures' and 'dreamy background' requested in the prompt
- − Shadows on the man's face are a bit harsh compared to Ghibli's typical soft lighting
Verdict: Seedream 4.0 followed the stylistic instructions much more closely, delivering a beautiful hand-painted watercolor look with soft pastels and a dreamy atmosphere. Seedream 5.0 Lite performed better at preserving the original image's specific background and character likenesses, but it resulted in a standard digital anime look rather than the specific 'hand-painted texture' and 'dreamy' Ghibli style requested.
Intricate Floral Mandala
Text-to-Image“Perfectly symmetrical mandala made entirely of real flowers, petals, leaves, fruits, and seeds in vibrant natural colors, intricate layered patterns with radial symmetry, top-down view on a soft neutral background, hyper-detailed organic textures and subtle shadows, photorealistic, 8K masterpiece.”
AI Judge Analysis
Seedream 4.0
- + Successfully incorporates a wide variety of elements including seeds, large fruits, and textured pods.
- + Features rich, organic shadows and highly detailed individual textures.
- + Exhibits a complex, painterly depth with layered botanical elements.
- − Lacks perfect symmetry, as many elements on the left do not match the right.
- − The center of the mandala is somewhat messy and lacks clear radial definition.
Seedream 5.0 Lite
- + Achieves near-perfect radial symmetry as requested in the prompt.
- + Very clean, balanced composition with sharp clarity on all elements.
- + Excellent adherence to all prompt components including seeds (almonds), fruits (berries), and flowers.
- − Lighting is a bit flat compared to the more dramatic shadows in Model A.
- − The arrangement feels slightly more clinical/calculated than organic.
Verdict: Seedream 5.0 Lite is the clear winner because it followed the 'perfectly symmetrical' instruction much better than Seedream 4.0, which displayed significant anatomical nesting errors and asymmetry. While Seedream 4.0 had more interesting shadows, Seedream 5.0 Lite provided a cleaner, more accurate representation of a botanical mandala that included all requested elements like seeds and fruits in a balanced layout.
Golden Hour Stroll
Editing“Add dynamic motion to this photo: make hair blow in the wind, add leaves flying, energetic and lively feel.”
AI Judge Analysis
Seedream 4.0
- + Natural integration of autumn-like leaves that feel part of the scene.
- + Excellent hair movement that looks physically plausible and wind-swept.
- + Maintains original image quality and lighting perfectly.
Seedream 5.0 Lite
- + Strong prompt adherence regarding flying leaves.
- + Effective wind effect on the hair, creating a more dramatic look.
- + Good preservation of the subject's face and the dog.
- − The added green leaves look like stickers or overlays with inconsistent lighting.
- − The leaves lack motion blur, making them look static despite the 'dynamic' request.
- − A few leaves appear in front of the subject in a way that feels artificial.
Verdict: Both models successfully interpreted the request to add wind and leaves, but Seedream 4.0 is much more successful in creating a realistic result. While Seedream 5.0 Lite adds larger, more vibrant leaves, they lack the motion blur and lighting integration found in Seedream 4.0, which makes the latter feel like a cohesive photograph rather than an edit with overlays.
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
Seedream 4.0
- + Perfect text rendering of the name and establishment date
- + High-quality vector emblem style with sophisticated shading
- + Excellent composition with arched text and a centered banner
Seedream 5.0 Lite
- + Clean minimalist design that fits the 'vector emblem' prompt
- + Accurate color palette according to the prompt
- + Simple and clear steam graphic
- − Incorrect accent mark on 'CAFFÊ' (should be 'CAFFÈ')
- − Banner shape is slightly awkward with disconnected ends
- − Flat shading lacks the 'vintage' depth requested
Verdict: Seedream 4.0 followed all instructions perfectly, including accurate spelling and a classic arched typography that feels more high-end and appropriate for a historic brand like Caffè Florian. Seedream 5.0 Lite produced a decent minimalist logo but failed on the specific typography (using a circumflex instead of a grave accent) and felt less professional in its banner execution.
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
Seedream 4.0
- + Features a clear timeline layout with a logical flow.
- + Includes creative extra details like the crew names and the Tranquility pin icon.
- + Excellent text rendering for the main titles and numeric labels.
- − Icons lack a consistent art style; the Moon and Lunar Module have different rendering styles.
- − The red rings around Earth and Moon look like hand-drawn strokes rather than clean vector paths.
- − Spelling error in 'Translunar' (broken into two lines awkwardly).
Seedream 5.0 Lite
- + Strict adherence to the NASA-inspired color palette and flat-vector style.
- + Consistent iconography across all six steps with high-quality illustrations.
- + Professional, clean typography and grid-based composition.
- − The 'Tranquility' text is slightly less polished than the main headers.
- − Lunar orbit and Translunar icons are a bit minimalist compared to the detailed spacecraft.
Verdict: Seedream 5.0 Lite is the clear winner as it masterfully executes the requested 'flat-vector' style with professional, crisp lines and a consistent NASA-inspired palette. Seedream 4.0 has more varying art styles between its icons, resulting in a less cohesive infographic look despite its good text rendering.
