AI Judge Analysis
Seedream 4.5
- + Excellent adherence to the complex spatial layering prompt.
- + Highly realistic lighting, textures, and refractions.
- + Naturalistic plant and book textures.
- − The glass cube has no top panel, making the book appear to float slightly above the edges.
Stable Diffusion 3.5 Large Turbo
- + Clean, modern aesthetic with sharp lines.
- + High resolution and clear subjects.
- − Failed the spatial prompt: the red book is inside the cube rather than on top.
- − The plant is beside the cube rather than behind it.
- − The black frame on the cube was not requested.
Verdict: Seedream 4.5 followed every detail of the prompt, correctly placing the sphere inside, the book on top, and the plant behind the glass, all while maintaining a high level of photographic realism. Stable Diffusion 3.5 Large Turbo produced a visually clean image but failed on almost all spatial instructions, placing the book inside and the plant to the side.
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.”
Seedream 4.5
Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.5
- + Excellent adherence to the 'candid street photo' aesthetic with realistic skin textures and lighting.
- + Successfully incorporates motion blur from passing cars and high-quality rain/puddle reflections.
- + Accurate and coherent bicycle details combined with expressive, detailed facial features.
- − The 'imperfect framing' is perhaps too subtle, appearing quite professionally composed.
Stable Diffusion 3.5 Large Turbo
- + Features a red bicycle as requested.
- + Attempts the rain effect with vertical lines.
- − Major anatomical and structural errors, including the man's head and neck merging into his shoulder.
- − Does not follow the motion blur or bokeh/shallow depth of field requests.
- − Poor bicycle physics; the chain and frame are illogical and disconnected.
Verdict: Seedream 4.5 is the clear winner as it masterfully identifies and executes every technical and artistic requirement of the prompt, resulting in a cinematic, photorealistic image. Stable Diffusion 3.5 Large Turbo fails on basic anatomy and perspective, producing a flat, unrealistic image with significant structural artifacts.
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.”
Seedream 4.5
Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.5
- + Exceptional skin texture with realistic pores, fine facial hair, and subtle scarring.
- + Masterful handling of lighting, showing complex reflections and warm highlights on the armor.
- + Incredible detail on the leather straps and fabric stitching as requested.
- − None notable.
Stable Diffusion 3.5 Large Turbo
- + Strong composition with clear braids and ornate armor engraving.
- + Good use of color contrast between the green underlayer and the dark metal.
- − Skin texture appears overly smooth and 'waxy', lacking the realism of the competitor.
- − The 'blood' effects look more like red paint than natural battlefield injuries.
- − Lower overall photorealism and fine detail in the hair and eyes.
Verdict: Seedream 4.5 produces a significantly more lifelike and professional image, capturing the 'battle-worn' aesthetic through subtle scars and realistic dirt rather than the crude red markings seen in Stable Diffusion 3.5 Large Turbo. Seedream 4.5 also excelled at the technical request for leather and cloth textures, delivering a much more tactile and atmospheric result.
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.”
Seedream 4.5
Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.5
- + Excellent adherence to the menu structure with clear sections for Appetizers, Pizza, and Mains.
- + Clean, professional layout that looks like a functional graphic design piece.
- + High-quality, realistic food photography with vibrant color-coded borders.
- − Text contains some spelling errors like 'Appetizters' and 'Festaurant'.
- − Repeating list items under each category rather than unique menu items.
Stable Diffusion 3.5 Large Turbo
- + Good interpretation of the 'colorful food photos in grid' part of the prompt.
- + Creative, artistic top-down food photography style.
- − Fails to present as a single cohesive menu, looking more like a scattered flat-lay photo.
- − Text is mostly illegible scribble and 'Mains' is misspelled as 'Mians'.
- − Missing the specific 'appetizers' section requested in the prompt.
Verdict: Seedream 4.5 is the clear winner as it produces a professional, functional menu layout that accurately reflects all categories requested in the prompt. While Stable Diffusion 3.5 Large Turbo has nice food photography, it misses the graphic design aspect of a modern menu, and its text is largely unreadable.
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 text rendering with impressive fiery effects and perfect accuracy.
- + High-quality photorealistic texture on the bun, meat, and vegetables.
- + Dynamic composition with motion-blurred ingredients that conveys the 'exploded' concept well.
- − The burger is mostly assembled rather than fully 'exploded' with all main layers separated.
Stable Diffusion 3.5 Large Turbo
- + Strong 'fiery' atmosphere with glowing embers and smoke.
- + Good centering of the subject matter.
- − Failed to include any of the requested text or the starburst element.
- − Image quality appears more like a digital illustration or 3D render than 'photorealistic'.
- − The burger is not 'exploded'; it is a static stack with a skewer through it.
Verdict: Seedream 4.5 is the clear winner as it followed every instruction, including complex text rendering and specific layout elements like the starburst. Stable Diffusion 3.5 Large Turbo failed to generate any text and produced a much less realistic image that did not capture the 'exploded' motion requested.
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 text rendering with perfect spelling and realistic chalk texture.
- + Highly accurate adherence to the specific date and menu items requested.
- + Realistic chalkboard aesthetic with natural smudges and varied handwriting styles.
- − Redundant price for the first item listed on two lines.
Stable Diffusion 3.5 Large Turbo
- + Clean aesthetic for the cafe environment.
- − Significant spelling errors throughout the board (e.g., 'apri 3l', 'ocotpgs', 'lerbs').
- − Handwriting looks like a digital font rather than authentic chalk.
- − Failed to include the specific year 2026 correctly.
Verdict: Seedream 4.5 is the clear winner as it successfully rendered all requested text with high accuracy and a realistic chalk texture. In contrast, Stable Diffusion 3.5 Large Turbo struggled with basic spelling, failed to complete the date, and produced text that looks like a digital font instead of handwritten chalk.
The Reversed Rodeo
Text-to-Image“Horse riding astronaut in space — horse on top, not vice versa. Surreal, highly detailed, cinematic.”
Seedream 4.5
Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.5
- + Excellent cinematic lighting and atmosphere with a detailed nebula background.
- + High level of detail on the astronaut's suit and the horse's anatomy.
- + Maintains a consistent surreal and high-quality aesthetic throughout the image.
- − Fails the specific logic constraint; the astronaut is on top of the horse, which is the standard configuration.
Stable Diffusion 3.5 Large Turbo
- + Clean, sharp rendering with clear contrast against the planet's horizon.
- + Stable horse anatomy and realistic astronaut suit modeling.
- − Fails the specific logic constraint; the astronaut is on top of the horse.
- − The composition is a bit flatter and less 'surreal' or 'cinematic' than Model A.
Verdict: Both Seedream 4.5 and Stable Diffusion 3.5 Large Turbo failed the negative constraint/spatial instruction of having the horse on top of the astronaut. However, Seedream 4.5 is the superior visual output due to its rich, cinematic lighting and more evocative space environment, whereas Stable Diffusion 3.5 Large Turbo feels more like a standard composite.
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.”
Seedream 4.5
Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.5
- + Excellent photorealism in the capybara's fur and the taxi interior.
- + Accurately depicts the businesswoman looking at her phone with a bored expression.
- + Perfect text rendering on the driver's cap.
- − The capybara's paws look slightly more like human hands/fingers in gloves than natural paws.
Stable Diffusion 3.5 Large Turbo
- + Dynamic lighting with colorful bokeh in the background.
- + Good side-profile composition of the capybara's head.
- − Failed to include the businesswoman in the back seat; the figure is in the passenger seat.
- − Text on the cap is garbled and unreadable.
- − The capybara's paw/hand interaction with the steering wheel is anatomically messy.
Verdict: Seedream 4.5 followed the prompt instructions precisely, capturing all characters and their specific actions with high realism. Stable Diffusion 3.5 Large Turbo failed on several prompt elements, including the position of the passenger, the text on the hat, and the boredom expressed by the human character.
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.”
Seedream 4.5
Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.5
- + Perfect text rendering for all requested details including the date, time, and location.
- + Atmospheric cinematic lighting with a realistic glowing jack-o-lantern.
- + Strong composition that looks like a professional digital movie poster or high-end invitation.
- − The thorns at the bottom appear more like barbed wire than natural vines.
Stable Diffusion 3.5 Large Turbo
- + Features a clear, distinct border with thorns and webs as requested.
- + Good use of the parchment texture for the background.
- − Failed to include the required scroll banner and specific event details (Date, Time, Location).
- − The text 'Halloween Party' is incomplete and lacks the requested gothic elegance.
- − The central pumpkin has a floating, clip-art appearance with inconsistent lighting.
Verdict: Seedream 4.5 is the clear winner as it followed every instruction, including the complex text requirements for the date and location, while maintaining a high-quality cinematic aesthetic. Stable Diffusion 3.5 Large Turbo failed to include the majority of the requested text and used a much simpler, less polished art style.
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.”
Seedream 4.5
Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.5
- + Excellent text rendering with clean, bold typography.
- + High-quality 3D shading and realistic PBR material effects on the salmon.

- − Significant spelling error with 'SIIHI' instead of 'SUSHI'.
- − The flag icon is incorrect, resembling the flag of Poland rather than Japan.
- − Background is a dull grey-blue rather than a solid light blue as requested.
Verdict: Seedream 4.5 captures the prompt's requirements perfectly, delivering clean typography and a correct national flag alongside high-quality textures. Stable Diffusion 3.5 Large Turbo fails on basic text accuracy and provides an incorrect flag, which detracts from the cultural theme of the image.
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.”
Seedream 4.5
Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.5
- + Successfully includes all four requested animals: retriever, kitten, bunny, and fox kit.
- + Dynamic composition perfectly captures the 'playfully chasing' action described in the prompt.
- + Excellent lighting with clear god rays, dew sparkles, and a warm sunrise glow.
- − The fox kit features slightly stylized, oversized eyes that border on 3D animation style rather than pure photorealism.
Stable Diffusion 3.5 Large Turbo
- + Attractive backlighting and rim light on the fur.
- + High-contrast, vibrant colors.
- − Failed to include all animals, missing the bunny and the fox kit.
- − Static pose that ignores the 'chasing' and 'tumbling' action requested.
- − Anatomical issues, particularly where the kitten and puppy limbs intersect.
Verdict: Seedream 4.5 is the clear winner as it followed every detail of the complex prompt, including all four distinct animal species and the specific action of them chasing butterflies. Stable Diffusion 3.5 Large Turbo failed on prompt adherence, providing only two types of animals in a static pose and showing significant anatomical merging between the subjects.
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.”

Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.5
- + Excellent typography with perfect spelling and accent marks.
- + Clean vector emblem style with a balanced layout.
- + Highly professional and authentic minimalist logo feel.
- − The 'Est. 1720' text is slightly off-center within its banner.
Stable Diffusion 3.5 Large Turbo
- + Dynamic shading and lighting on the central object.
- + Creative integration of a coffee mug handle with the cloche dome.
- − Misspelled text with 'Caffeé' having two 'e's and a strange artifact in 'Florin'.
- − Design is less minimalist and more illustrative, deviating from the requested vector emblem style.
- − The background texture is heavy and blotchy rather than 'subtle'.
Verdict: Seedream 4.5 is the clear winner as it produces a professional-grade logo with perfect spelling and a clean minimalist aesthetic. Stable Diffusion 3.5 Large Turbo struggles with the text rendering and misses the 'minimalist' brand identity, opting for a busier, more cluttered illustration.
