Pose & Character Mashup
Editing“Use Image 1 as the exact pose reference and Image 2 as the character reference. Recreate the person/character from Image 2 in the exact dynamic pose and body position from Image 1. Keep the exact face, hair, clothing style/details, and expression from Image 2. Match the lighting and environment of Image 1. The final image must show the character from Image 2 performing the precise action/pose from Image 1 with perfect anatomy and natural integration.”
AI Judge Analysis
Seedream 4.5
- + Excellent character preservation of the face, sunglasses, and scarf from Image 2.
- + Matches the yellow background and red ottoman from Image 1 perfectly.
- + High-quality skin texture and clothing details.
- − The pose is significantly simplified; the legs are parallel rather than crossed like in Image 1.
- − The torso orientation is upright rather than the deep lateral bend seen in the reference.
Seedream 5.0 Lite
- + Successfully replicates the complex crossed-leg and tilted-torso pose from Image 1.
- + Accurately carries over the character features including the scarf, shades, and black outfit.
- + Maintains the lighting and environment of the source image.
- − Slightly less crisp facial detail compared to model A.
- − The left hand (reaching down) has some anatomical blurring/distortion.
Verdict: While Seedream 4.5 offers higher facial clarity, it fails to replicate the specific 'dynamic pose' requested, defaulting to a standard standing position. Seedream 5.0 Lite successfully captures the difficult anatomical arrangement of the crossed legs and tilted body from Image 1 while maintaining the character identity of Image 2, making it the better choice for the complex edit instructions.
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 4.5
- + Excellent handling of light refraction and shadows on the table surface.
- + Very realistic texture on the book's cover and pages.
- + Sharp focus and high-resolution details on the glass edges.
- − The blue sphere is partially clipping through the glass wall.
- − The glass cube has an inconsistent geometric shape at the base.
Seedream 5.0 Lite
- + Strong spatial coherence with the sphere clearly inside the cube and the book resting on top.
- + Beautiful soft lighting that accurately reflects the requested window light.
- + Clean, logical composition with a clear background plant.
- − The glass cube appears slightly more like a plastic container due to thinner walls.
- − The sphere has a very matte finish compared to the highlights elsewhere in the scene.
Verdict: Seedream 5.0 Lite followed all spatial instructions perfectly, placing the sphere clearly inside the cube and the plant behind it with a more natural depth of field. Seedream 4.5 had more impressive lighting and material textures, but failed on the physics of the scene, with the sphere clipping through the glass and the cube's geometry appearing distorted at the bottom.
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
Seedream 4.5
- + Excellent typography with zero spelling errors across all menu items.
- + Authentic chalk texture with realistic smudges and varied letter weights.
- + Clean layout that balances the cursive title with legible body text.
- − Repeated the price for the first item on its second line unnecessarily.
Seedream 5.0 Lite
- + Natural-looking green chalkboard surface with authentic wear and tear.
- + Consistent handwriting style across the entire board.
- − Significant spelling errors including 'Heriss', 'Beliter', 'frese', and 'optoons'.
- − Text sits oddly on top of underline artifacts rather than looking integrated.
Verdict: Seedream 4.5 is the clear winner because it rendered the text with 100% spelling accuracy and a much more sophisticated chalk texture. While Seedream 5.0 Lite captured a nice vintage chalkboard aesthetic, it failed significantly on text rendering, producing multiple typos for the specific items requested.
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
Seedream 4.5
- + Excellent dynamic motion with realistic motion blur
- + Perfect integration of the fiery starburst for the price
- + Superior text effects with high-quality flame textures
- − The composition is a bit crowded at the bottom right
Seedream 5.0 Lite
- + Clear and balanced vertical composition
- + Very realistic textures on the tomato and patty
- + Good adherence to the 'exploded' request with distinct layers
- − The price starburst looks like a simple neon clip-art rather than being integrated into the scene
- − Lacks the sense of dynamic motion requested in the prompt
Verdict: Seedream 4.5 captures the 'dynamic' and 'fiery' aspects of the prompt much more effectively than Seedream 5.0 Lite, using motion blur and more sophisticated text effects. While Seedream 5.0 Lite has great ingredient clarity, its price tag and text feel like flat overlays rather than part of the 3D environment.
Man and Car in California
Editing“Make a photo of the man driving the car down the California coastline”
AI Judge Analysis
Seedream 4.5
- + Retains a high level of clothing detail from the source image, including the specific pattern of the coat and the style of the boots.
- + The man's facial features and Hairstyle are very accurately preserved from the source.
- + Shows a more intimate, detailed view of the car's interior.
- − The open car door makes no sense while the car is supposedly in motion down a coastline.
- − The lighting is flat and overcast, lacking the visual appeal typically associated with a California coast photo.
Seedream 5.0 Lite
- + Excellent composition that captures the car 'driving' realistically on a road with motion blur.
- + The California coastline environment is vibrant and aesthetically pleasing with clear blue skies.
- + Maintains the integrity of the original car model and the man's identity well.
- − Loses the detail of the man's lower outfit (pants and boots) due to the car's body panels.
- − Minor distortion on the steering wheel where the hands grip it.
Verdict: Seedream 5.0 Lite is the clear winner as it creates a logical and visually stunning scene of the car in motion on a coastal road. While Seedream 4.5 preserved clothing details like the boots effectively, it failed the logic test by showing the car moving with the driver's side door wide open.
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 4.5
- + High-quality, realistic food photography with vibrant colors.
- + Clean, professional layout that matches the 'modern minimalist' aesthetic well.
- + Good use of colorful frames to differentiate sections.
- − Text is largely nonsensical or repetitive (e.g., 'Appetizters', 'Festaurant').
- − Prices are unrealistic for the casual dining context described ($79-$99).
- − Section headers and items are poorly aligned with the images.
Seedream 5.0 Lite
- + Perfect text rendering for all titles, menu items, and pricing.
- + Accurate grid layout that follows the 'colorful food photos in grid' instruction.
- + Strong adherence to the 'bold sans-serif fonts' and 'vibrant accents' request.
- − Food photography is slightly more generic/stock-like compared to Model A.
- − The 'star' icons in the header feel a bit dated rather than purely 'modern minimalist'.
Verdict: Seedream 5.0 Lite is the clear winner due to its exceptional handling of text and layout, producing a fully functional menu with correct spelling and logical pricing. While Seedream 4.5 offers more artistic food photography, it fails significantly on the professional layout aspects with nonsensical text and random pricing that makes the design unusable.
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 4.5
- + Captures a very convincing 'candid' and 'imperfect' framing as requested.
- + Excellent portrayal of motion blur from passing cars in the background.
- + High level of detail on the man's face and his weathered, dirty work jacket.
- − The wrench is floating/not correctly held by the hand.
- − The bicycle chain is detached and floating in space beneath the frame.
- − The man appears to be kneeling directly into a deep puddle in an unnatural way.
Seedream 5.0 Lite
- + Superior technical rendering of the hand-to-bike interaction.
- + Strong bokeh effect and realistic rain ripples on the pavement.
- + Better preservation of bicycle anatomy and realistic clothing texture.
- − The composition feels more staged and less like a 'candid street photo'.
- − Missing some of the requested 'imperfect framing' compared to the other model.
Verdict: While Seedream 4.5 does a great job capturing the 'imperfect' and gritty atmosphere of the prompt, it suffers from significant anatomical errors with the bicycle and the wrench. Seedream 5.0 Lite produces a much more coherent and technically sound image where the man's hands actually interact with the bike parts correctly, making it the more realistic choice overall.
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 4.5
- + Perfectly preserves facial features and glasses
- + Maintains identical lighting and background
- + Seamlessly integrates the hairline with existing sideburns
- − Hair shape feels a bit uniform and rounded
- − Hair texture is slightly soft compared to the original beard
Seedream 5.0 Lite
- + Very realistic hair texture and styling
- + Good integration of forehead wrinkles with the new hairline
- + Excellent preservation of the overall scene
- − Slightly alters the shape of the nose
- − Subtle changes to the eyelid shape and facial structure
Verdict: Both models did an excellent job with the edit. Seedream 4.5 is the winner because it achieved a near-perfect pixel-for-pixel preservation of the original facial features and glasses while adding the hair, whereas Seedream 5.0 Lite slightly modified the person's nose and eyes during the generation process.
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 4.5
- + Excellent text rendering with clean, bold typography.
- + High-quality material rendering with realistic gloss and textures on the sushi.
- + Effective use of depth of field and soft lighting to create a premium 3D look.
- − The diorama base has a rough, sandy texture that feels slightly disjointed from the 'refined' request.
- − Layout is slightly more crowded with the large text size.
Seedream 5.0 Lite
- + Perfect adherence to the 'ultra-clean' aesthetic with a smooth, white diorama base.
- + Varied sushi selection including nigiri, maki, and tamago with accurate garnishes like wasabi and ginger.
- + Better overall balance and composition within the square frame.
- − Materials look slightly more like plastic/clay and less like realistic food compared to Model A.
- − Minor misalignment in the red circle of the flag icon.
Verdict: Both models followed the prompt exceptionally well, adhering to the 45° isometric perspective and text requirements. Seedream 4.5 produces more realistic food textures and superior typography, while Seedream 5.0 Lite captures the 'ultra-clean' miniature aesthetic more effectively with its smooth base and diverse sushi platter. Seedream 5.0 Lite is the preferred choice for its superior composition and cleaner visual style that better fits the 'cartoon miniature' request.
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 4.5
- + Excellent source preservation of the landscape and village layout
- + Provides a realistic transition to a night sky while maintaining the mountain peak lighting
- − The 'subtle, glistening stars' are barely visible, looking more like sensor noise or faint streaks
- − Retains a warm orange glow on the mountain peak that feels slightly disconnected from the new dark sky
Seedream 5.0 Lite
- + Successfully renders clear, glistening stars as requested
- + Adjusts the lighting on the mountain peak to a cooler, more moonlight-appropriate tone
- + Excellent preservation of the original village and valley geometry
- − None notable; it followed all instructions while maintaining high image fidelity
Verdict: Both models did an exceptional job of preserving the complex details of the original image while changing the sky. Seedream 5.0 Lite is the winner because it followed the specific prompt for 'glistening stars' much more clearly than Seedream 4.5, and it appropriately shifted the color temperature of the mountain peak's highlight to better suit a nighttime scene.
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 4.5
- + Retains a high degree of facial likeness to the original subject.
- + Successfully incorporates all requested elements: hockey sticks/gloves, a dog, and a news desk with a microphone.
- + Maintains the living room background from the source image, blending the desk into the existing environment.
- − The hands are noticeably small and poorly rendered/shriveled.
- − The 'exaggerated' caricaturization is primarily just an enlarged head rather than a stylized artistic interpretation.
Seedream 5.0 Lite
- + Adopted a consistent and clean vector illustration style typical of humorous caricatures.
- + Provides a more professional 'TV News Anchor' environment with studio lighting and a nameplate.
- + Clearer rendering of the dog and hockey stick compared to the first model.
- − Loss of specific facial likeness; the subject now looks like a generic cartoon character.
- − Replaced the background entirely, losing the 'source preservation' aspect of the prompt.
Verdict: Seedream 4.5 is the winner because it successfully maintains the subject's literal face and the original background while adding the requested desk and hobbies. While Seedream 5.0 Lite produces a very clean cartoon, it fails as an image edit by completely replacing the person's unique features with a generic illustration style.
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 unavailable for this challenge.
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 4.5
- + Excellent composition with the Empire State Building framing the subject.
- + Higher level of detail in the costume textures and urban environment.
- + Dynamic lighting with realistic rim light on the subject's hair and clothing.
- − The left hand/glove has slightly messy finger geometry.
- − The chest emblem looks more like a sticker than an integrated part of the suit.
Seedream 5.0 Lite
- + Clean, smooth aesthetic with good facial features.
- + Accurate full-body framing and adherence to the 'hands on hips' prompt.
- + The cape flow is very dramatic and well-rendered.
- − The background looks a bit more blurred and less detailed compared to Model A.
- − The lighting is slightly flatter and less cinematic than Model A.
Verdict: Both models followed the prompt exceptionally well, producing near-identical interpretations of the subject and setting. Seedream 4.5 is the winner due to its superior lighting and the high level of detail in the New York cityscape, which makes for a more convincing hyper-photorealistic image than Seedream 5.0 Lite.
Neutral Expression to Genuine Smile
Editing{
"action": "image_edit",
"reference": "uploaded neutral portrait",
"change": "Warm genuine Duchenne smile: lips curved up, slight natural teeth, soft eye crinkles, subtle cheek raise",
"details": "Realistic smiling skin (dimples if present, soft cheek shadows), slightly brighter eyes; keep exact eye shape/color/iris",
"preserve_exact": "Face identity/structure, eyes/nose/lips/eyebrows, hair, skin texture/pores/freckles, makeup, clothing, head pose, background, lighting, shadows, framing",
"no_changes": "No face shape change, no new features, no gaze shift, no hair/clothing/lighting/background edits",
"style": "Ultra-photorealistic 8K portrait, sharp face focus, natural soft lighting, realistic skin glow"
}
AI Judge Analysis
Seedream 4.5
- + Excellent preservation of the original face structure and hair strands.
- + High visual clarity and skin texture consistency.
- + Natural-looking teeth and lip curvature.
- − The eyes remain very 'neutral' and miss the requested Duchenne crinkle/compression.
- − The smile looks slightly pasted on due to lack of mid-face movement.
Seedream 5.0 Lite
- + Captured the Duchenne smile better by narrowing the eyes and adding soft crinkles.
- + Successfully brightened the eyes as requested while maintaining iris detail.
- + Perfectly preserved the hair, clothing, and background elements.
- − The teeth shape is slightly less uniform compared to Model A.
- − Very subtle change in the tip of the nose shape.
Verdict: Both models did an exceptional job of preserving the source image's identity, hair, and lighting. Seedream 5.0 Lite is the winner because it actually followed the 'Duchenne smile' instruction by modifying the eyes to look genuinely happy, whereas Seedream 4.5 only changed the mouth, resulting in a slightly 'dead' expression.
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 unavailable for this challenge.
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 4.5
- + Successfully adds wind-blown hair and flying autumnal leaves.
- + Increases the impression of motion and energy through a wider gait and lens flare.
- + Maintains the subject's likeness while effectively modifying her posture for dynamism.
- − The leaf color change to brown/orange is an unnecessary departure from the lush green summer setting of the source image.
- − Makes minor changes to background trees and lighting that weren't requested.
Seedream 5.0 Lite
- + Extremely high source preservation; the background and subject's body remain identical to the original.
- + Adds windy hair and leaves as requested while keeping the original green color palette.
- − The added green leaves look like stickers floating on the surface of the image rather than part of the 3D scene.
- − The wind effect on the hair is slightly less dramatic and 'energetic' than in Seedream 4.5.
Verdict: Seedream 4.5 (Model A) provides a much more convincing 'energetic' feel by slightly adjusting the subject's pose and adding a dynamic motion blur to the leaves, even though it changed the leaf color to brown. Seedream 5.0 Lite (Model B) preserved the original image much better, but the added leaves look like flat 2D overlays and lack the sense of movement found in the other model.
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 4.5
- + Perfect text rendering for both 'Caffè Florian' and 'Est. 1720'.
- + Excellent composition with a strong vector emblem feel.
- + Includes a subtle grainy texture on the light background as requested.
- − The steam element is very small and lacks prominence.
- − The cloche is a bit simplified/flat compared to typical vector art.
Seedream 5.0 Lite
- + Closer interpretation of a 'minimalist' logo with better use of negative space.
- + More dynamic steam graphics on both sides of the cloche.
- + Features a more traditional decorative banner for the date.
- − Text error in the primary name - uses 'Caffé' instead of 'Caffè' (grave accent).
- − The 'Est. 1720' text is slightly off-center within the banner.
- − The background texture is very faint, resulting in a slightly washed-out look.
Verdict: Seedream 4.5 is the winner because it identifies and renders the specific text requirements perfectly, including the correct grave accent in 'Caffè'. While Seedream 5.0 Lite offers a more elegant and minimalist logo composition, its spelling error and slight misalignment issues make it less usable for a finished brand asset.
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 4.5
- + Excellent infographic layout with a clear timeline structure and clean lines.
- + Very high-quality vector-style icons, especially the lunar module and Saturn V.
- + Perfect adherence to the requested color palette and consistent iconography.
- − The icon for 'Descent' appears to be a satellite or probe rather than a descending lunar module.
- − The trajectory arc for 'Translunar' is a bit small compared to the other stages.
Seedream 5.0 Lite
- + Accurate iconography for the descent and landing stages showing the lunar module.
- + Clear, bold typography that is very legible.
- + Strong adherence to the flat-vector style requested.
- − The 'Translunar' icon is just a plain line without much context or the requested trajectory arc style.
- − The crew icons are more generic and lack the layout polish seen in the other model.
- − Minor spelling error ('TRANSLUMAR' instead of 'TRANSLUNAR').
Verdict: Both models followed the prompt closely, but Seedream 4.5 produced a much more professional and aesthetically pleasing infographic layout. While Seedream 5.0 Lite had more accurate lunar module icons for the final stages, Seedream 4.5's composition, color usage, and overall vector quality make it look like a real poster, despite the 'Descent' icon error and the misspelled 'Tranquility' (which both models actually misspelled similarly).
