Seedream 4.0
Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.0
- + Excellent adherence to the complex spatial prompt.
- + High degree of photorealism with natural lighting and depth of field.
- + Accurately places the book on top and the plant behind the glass.
- − The glass cube has some slight perspective distortion on the left edge.
Stable Diffusion 3.5 Large Turbo
- + Clean, sharp rendering of the objects.
- + Good lighting and shadows across the table surface.
- − Failed to place the book on top of the cube; instead, the cube is on the book.
- − The sphere and book are both inside the cube, which contradicts the prompt instructions.
- − The plant is to the side rather than behind the cube.
Verdict: Seedream 4.0 followed all spatial instructions perfectly, including the specific placement of the red book on top of the cube and the plant behind it. Stable Diffusion 3.5 Large Turbo struggled with spatial reasoning, placing the cube on top of the book and putting the plant to the side. Seedream 4.0 is the clear winner for its superior prompt adherence and realistic photographic style.
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 4.0
Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.0
- + Excellent adherence to the 'motion blur from passing cars' prompt requirement
- + Highly realistic skin texture and organic environment composition
- + Realistic water reflections and shallow depth of field
- − Anatomical issues with the subject's feet
- − The rear bicycle wheel has some structural inconsistencies
Stable Diffusion 3.5 Large Turbo
- + Clean, sharp image with minimal artifacts
- + Correctly depicted a red bicycle and an elderly man
- − Failed to include motion blur for passing cars
- − Lacks the requested 'natural skin texture' and appears more illustrative/plastic
- − Bicycle anatomy is fused with the subject's body and the ground
Verdict: Seedream 4.0 followed the complex prompt requirements much more accurately, successfully capturing the atmospheric elements like light rain, motion blur, and cinematic reflections. Stable Diffusion 3.5 Large Turbo produced a much more sterile, stylized image that lacked the requested realism and failed to incorporate several key motion and texture descriptors.
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 4.0
Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.0
- + Excellent photorealism with lifelike skin texture and lighting
- + Perfect adherence to the 'beads in braids' and 'warm torchlight' requirements
- + Beautiful rendering of bokeh sparks and depth of field
- − None identified
Stable Diffusion 3.5 Large Turbo
- + Clear armor engraving details
- + Consistent braided hairstyle
- − Missed the request for beads in the hair
- − Failed the warm torchlight/spark atmosphere, appearing as daylight
- − Skin texture and lighting look digital and artificial compared to Model A
Verdict: Seedream 4.0 produced a superior image with convincing photorealistic textures and atmospheric lighting that perfectly matched the prompt's mood. Stable Diffusion 3.5 Large Turbo failed to include the requested beads and created a flat, digitally-saturated look that lacked the lifelike quality and dramatic torchlight effects seen in Seedream 4.0.
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 4.0
Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.0
- + Clear legible typography for main categories
- + Logical grid layout of food images
- + High photographic realism in the food assets
- − Lack of actual menu items/dishes listed under headings
- − Text is crowded and overlaps with images poorly
- − Does not really function as a menu without item details
Stable Diffusion 3.5 Large Turbo
- + Successfully includes menu item lines and pricing placeholders
- + Better sense of 'minimalist' design for a brand identity
- + Creative use of a flat-lay grid for food items
- − Severe spelling errors such as 'Mians' and illegible gibberish text
- − Food images look somewhat artificial and overly saturated
- − Missing the 'Appetizers' section requested in the prompt
Verdict: Both models struggled to create a fully functional menu. Seedream 4.0 produced much better food photography and legible category headers but failed to include any actual menu content. Stable Diffusion 3.5 Large Turbo attempted a more comprehensive layout with pricing and item lists, but the text is largely gibberish and contained spelling errors in the headers.
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.”
Seedream 4.0
Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.0
- + Excellent adherence to text instructions, including the main title, secondary message, and price with a starburst effect.
- + Dynamic and realistic 'exploded view' composition with effective motion blur and high texture detail on the food.
- + Captures the fiery atmosphere with realistic lighting and embers that integrate well with the text.
- − The price text is incorrect, showing €5.99 instead of the requested €6.99.
- − The composition shows one and a half burgers instead of a single burger exploding.
Stable Diffusion 3.5 Large Turbo
- + High contrast colors and a symmetrical layout that creates a strong focal point.
- + Good depiction of fire and embers in the background.
- − Completely failed to include any of the requested text elements.
- − Failed to create the 'exploded' effect, showing a mostly assembled burger held by a skewer.
- − Lacks photorealistic detail, appearing more like a digital illustration or 3D render.
Verdict: Seedream 4.0 followed the prompt closely, successfully integrating the complex text elements and the specific 'mid-air' exploded composition, despite a minor error in the price digits. Stable Diffusion 3.5 Large Turbo failed to include any text or the core exploded burger concept, resulting in a static image that looks more like a stylized graphic than a photorealistic ad.
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.”
Seedream 4.0
Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.0
- + Excellent text accuracy, correctly rendering all specific menu items and prices.
- + Highly realistic chalk texture with smudges and natural handwriting variations.
- + Authentic cafe environment with appropriate depth of field.
- − The '3' in 30 is slightly smaller than the rest of the date line.
Stable Diffusion 3.5 Large Turbo
- + Clean, modern aesthetic with pleasant lighting.
- + Follows the general 'chalkboard' brief.
- − Numerous spelling errors including 'ocopus', 'trulale', and 'apri'.
- − Failed to render the full date and prices correctly.
- − The text looks like a digital font rather than authentic hand-lettered chalk.
Verdict: Seedream 4.0 followed the complex text requirements perfectly, rendering every menu item and the specific date with realistic chalk textures and handwriting. Stable Diffusion 3.5 Large Turbo struggled significantly with the text, producing several misspellings and failing to maintain the 'handwritten' aesthetic requested in the prompt. Seedream 4.0 is the clear winner for its superior prompt adherence and realism.
The Reversed Rodeo
Text-to-Image“Horse riding astronaut in space — horse on top, not vice versa. Surreal, highly detailed, cinematic.”
Seedream 4.0
Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.0
- + High visual fidelity with cinematic lighting and a detailed nebula.
- + Excellent texture work on the horse's coat and the astronaut's suit.
- − Completely failed the reversal logic constraint with the astronaut riding the horse.
- − Anatomical issues with the horse's front legs appearing stunted and deformed.
Stable Diffusion 3.5 Large Turbo
- + Clean composition with a clear 'surreal' aesthetic.
- + Sharp rendering of the orbital environment and planetary curvature.
- − Failed the core 'horse on top' prompt instruction, depicting a standard riding scene.
- − The horse's rear legs and hooves bleed into the background shadows unnaturally.
Verdict: Both Seedream 4.0 and Stable Diffusion 3.5 Large Turbo failed to follow the specific 'horse on top' instruction, which was a test of prompt adherence for complex spatial relationships. Seedream 4.0 produced a more cinematic and detailed image, but suffered from anatomical errors in the horse's legs, while Stable Diffusion 3.5 Large Turbo opted for a cleaner, flatter style that lacks the requested cinematic detail.
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 4.0
Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.0
- + Excellent adherence to the prompt including the businesswoman looking at a phone
- + Natural textures for the capybara's fur and the leather interior of the taxi
- + Great urban atmosphere with the bokeh lights through the windows
- − The text on the cap and car door is nonsensical
- − Lighting on the businesswoman is slightly flat compared to the foreground
Stable Diffusion 3.5 Large Turbo
- + Strong cinematic lighting with vibrant bokeh in the background
- + The capybara's paws are positioned very well on the steering wheel
- − Failed to include the businesswoman looking at a phone; she is barely visible and and looking forward
- − The capybara's face looks a bit more like a hybrid or a cartoonish render rather than photorealistic
Verdict: Seedream 4.0 followed the complex prompt requirements much better, specifically capturing the secondary subject—the bored businesswoman on her phone—whereas Stable Diffusion 3.5 Large Turbo mostly ignored that detail. Seedream 4.0 also achieved a more convincing photorealistic texture for the animals and the car interior.
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 4.0
Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.0
- + Excellent adherence to all text requirements including dates and location
- + Highly detailed cinematic lighting and gothic aesthetic
- + Accurate interpretation of 'dark parchment' and thorny border elements
- − The text on the small scroll banner is slightly garbled and difficult to read
Stable Diffusion 3.5 Large Turbo
- + Clean graphic design style with a clear central jack-o-lantern
- + Well-defined silhouettes of trees and bats
- − Failed to include the requested date, time, and location details
- − Ignored the specific 'Invitation' and banner text requirements
- − Art style is more cartoonish than the requested 'cinematic' vintage look
Verdict: Seedream 4.0 followed the prompt instructions near-perfectly, incorporating the specific event details, the banner, and the dark gothic atmosphere requested. Stable Diffusion 3.5 Large Turbo failed to include most of the required text and produced a much simpler, less atmospheric image that did not meet the 'cinematic' or 'vintage' criteria.
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.

Seedream 4.0
Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.0
- + Excellent text rendering with no spelling errors.
- + Realistic fish textures and rice grains that follow the PBR material request.
- + Clean, solid blue background with professional studio lighting.

- + Strong 3D isometric look with good shadows.
- − Significant spelling error with 'SIIHI' instead of 'SUSHI'.
- − The flag icon is incorrect, resembling Poland or Indonesia rather than Japan.
- − The background is a gradient grey-blue rather than the requested solid light blue.
Verdict: Seedream 4.0 followed all instructions perfectly, including the specific text requirements and the solid background color. Stable Diffusion 3.5 Large Turbo failed on the spelling of 'SUSHI' and generated an incorrect flag, making Seedream 4.0 the clear winner for accuracy and professional finish.
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 4.0
Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.0
- + Successfully includes all four requested animals (dog, cat, bunny, fox).
- + Excellent dynamic composition with animals interacting and 'tumbling' as requested.
- + Superb lighting effects with realistic god rays and sparkling dew.
- − The fox kit has somewhat unnatural black paws/limbs coherence.
- − Background bokeh creates some floating white artifacts that look like water droplets rather than light.
Stable Diffusion 3.5 Large Turbo
- + Clean, sharp focus on the central characters.
- + Vibrantly colored butterflies.
- − Failed to include the baby bunny and the red fox kit.
- − The style is more '3D render' or 'illustration' than the requested 'hyper-photorealistic'.
- − The anatomy of the right-most animal is an ambiguous mix of a cat and fox rather than a distinct species.
Verdict: Seedream 4.0 followed every detail of the complex prompt, including all four species of animals and the specific 'tumbling' action, while maintaining a convincing photographic style. Stable Diffusion 3.5 Large Turbo missed half of the requested animals and failed to capture the photorealistic requirement, leaning instead towards a stylized digital art look.
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.”
Seedream 4.0
Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.0
- + Excellent typography with correct spelling and accent placement.
- + Professional vector logo composition with clean lines.
- + Subtle, effective texture on a light background that enhances the vintage feel.
Stable Diffusion 3.5 Large Turbo
- + Dynamic shading and strong contrast in the vector art.
- + Good interpretation of the 'Est. 1720' banner with classic woodcut-style lines.
- − Incorrect spelling of 'Caffé' (rendered as 'Caffeé').
- − Strange anatomical merge of a cloche dome and a coffee mug handle.
- − The typography is cramped and slightly garbled at the end of 'Florian'.
Verdict: Seedream 4.0 followed all instructions perfectly, producing a clean, professional, and well-spelled logo that looks like a real brand identity. Stable Diffusion 3.5 Large Turbo struggled with the text spelling and produced a confusing visual hybrid of a cloche dome and a mug that ruined the minimalist aesthetic.
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.”
Seedream 4.0
Stable Diffusion 3.5 Large Turbo
AI Judge Analysis
Seedream 4.0
- + Excellent adherence to the requested 6-step chronological sequence.
- + Text is highly legible with correct names of the astronauts and mission stages.
- + Consistent flat-vector style with the specific NASA-inspired color palette requested.
- − Small spelling error in 'Surface' for step 5.
- − Individual step icons (especially the trajectory) are a bit simplistic compared to a professional infographic.
Stable Diffusion 3.5 Large Turbo
- + Strong aesthetic appeal with a high-quality 'modern vector' graphic design layout.
- + Effective use of the requested color palette across the entire poster.
- + Creative use of circular framing and astronomical graphics.
- − Failed to provide the logical 6-step numbered sequence requested in the prompt.
- − Text quality is very poor with significant gibberish and misspellings like 'Apoll.o' and 'Lamnar'.
- − Missing specific requested icons like the Saturn V rocket.
Verdict: Seedream 4.0 is the clear winner as it followed the complex structural requirements of the prompt, including a 6-step sequence with specific icons and labels. While Stable Diffusion 3.5 Large Turbo captured a more sophisticated artistic style, its failure to include the correct information and its use of nonsensical text makes it fail as an infographic.
