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.”
Seedream 4.0
Stable Diffusion 3.5 Medium
AI Judge Analysis
Seedream 4.0
- + Excellent lighting and atmospheric mood
- + Realistic glass reflections and shadows on the wooden surface
- + Perfect adherence to spatial positioning of all objects
Stable Diffusion 3.5 Medium
- + Natural-looking plant leaves
- + Clear transparency of the glass cube
- − The blue sphere is levitating unrealistically in the center of the cube
- − The glass cube perspective is slightly distorted
- − The lighting is flat compared to the requested window light
Verdict: Seedream 4.0 followed the prompt with much higher photorealism and spatial accuracy, placing the sphere logically on the bottom surface of the cube rather than levitating like in Stable Diffusion 3.5 Medium. Seedream 4.0 also more effectively captured the 'soft window light' through nuanced highlights and shadows on the table.
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 Medium
AI Judge Analysis
Seedream 4.0
- + Excellent adherence to the 'repairing' aspect of the prompt with tools on the ground.
- + Effective motion blur on the passing vehicle in the background.
- + Natural skin textures and realistic lighting for a rainy day.
- − Physical logic errors with the bicycle frame passing through the man's legs.
- − The tools on the ground look slightly floating and lack clear contact shadows.
Stable Diffusion 3.5 Medium
- + Strong atmospheric mood with vibrant reflections and heavy rain texture.
- + Dynamic composition with good use of negative space on the wet pavement.
- + Better focus on the 'candid' street photography aesthetic.
- − The man is just holding/leaning on the bike rather than 'repairing' it as requested.
- − The bicycle proportions are warped, particularly the handlebars and front basket.
- − The man's hands have significant anatomical distortion.
Verdict: Seedream 4.0 followed the specific action of the prompt much better, showing the man actively working with tools, whereas Stable Diffusion 3.5 Medium produced a more atmospheric but less accurate scene where the man is simply standing. While Seedream 4.0 has some clipping issues with the bike frame, its technical execution of the specific prompt details like motion blur and repairing makes it the superior choice.
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 Medium
AI Judge Analysis
Seedream 4.0
- + Excellent depiction of the requested beads in the braided hair
- + Highly realistic textures on the leather straps and armor engraving
- + Natural integration of the torchlight and bokeh sparks
- − The scars on the face are a bit faint
- − Slightly less intense 'battle-worn' expression compared to the alternative
Stable Diffusion 3.5 Medium
- + Strong facial expression and lifelike eyes
- + Good color contrast between the cool metal and warm torchlight
- + Intricate engraving on the cuirass
- − Missed the prompt requirement for small beads in the hair
- − Armor on the right shoulder appears warped and lacks the structural detail seen in Model A
- − Leather straps are less defined and detailed
Verdict: Seedream 4.0 followed all specific prompt requirements, including the small beads in the braids and the highly detailed leather straps, which Stable Diffusion 3.5 Medium missed. While Stable Diffusion 3.5 Medium captured a very intense and lifelike character, the anatomical and structural clarity of the armor in Seedream 4.0 makes it the superior choice for this requested portrait.
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 Medium
AI Judge Analysis
Seedream 4.0
- + Excellent typography with clean, readable, bold sans-serif fonts
- + High-quality, appetizing food photography with vibrant colors
- + Strong minimalist aesthetic that follows the prompt's structural requirements
- − Lacks actual menu item text or prices, focusing only on section headers
- − Composition feels slightly empty in the center
Stable Diffusion 3.5 Medium
- + Follows a realistic full menu layout including price points and item descriptions
- + Good grid-based organization of various food items
- + Conveys a sense of a complete document rather than just a header
- − Text is largely gibberish and poorly rendered
- − Food photos are small and less appetizing due to lower clarity
- − Significant drop in overall visual quality and sharpness compared to Model A
Verdict: Seedream 4.0 captures the aesthetic of a modern, professional minimalist design with high-quality photography and perfectly rendered typography. Stable Diffusion 3.5 Medium attempts a more complex full-menu structure, but fails significantly on text legibility and image clarity. Seedream 4.0 is preferred because it produces a result that looks like a finished professional graphic, whereas Stable Diffusion 3.5 Medium looks like a draft with corrupted text.
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 Medium
AI Judge Analysis
Seedream 4.0
- + Excellent sense of motion with the 'exploded' concept
- + Highly creative and high-quality glowing fire text effects
- + Dynamic composition with embers and swirling light
- − Failed the specific price instruction by showing €5.99 instead of €6.99
- − Rendering of the burger layers is slightly duplicated/illogical in some areas
Stable Diffusion 3.5 Medium
- + Perfect accuracy with the price text (€6.99)
- + Clear and legible typography
- + Solid photorealistic texture on the burger bun and patty
- − Failed the 'exploded burger' prompt; the burger is mostly assembled
- − The starburst design is very simplistic and lacks a 'fiery glowing effect'
- − Background fire lacks the depth and quality seen in the competitor
Verdict: Seedream 4.0 delivers a much more dynamic and visually exciting advertisement that perfectly captures the requested 'exploded' motion and fiery atmosphere, although it hallucinated the wrong price. Stable Diffusion 3.5 Medium followed the text instructions more accurately but failed the core 'exploded' prompt, resulting in a static image that lacks the 'magic' and energy 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.”
Seedream 4.0
Stable Diffusion 3.5 Medium
AI Judge Analysis
Seedream 4.0
- + Excellent text rendering with near-perfect spelling across all items.
- + Highly realistic chalk texture with smudges and natural handwriting variations.
- + Strong adherence to the specific menu items and date requested in the prompt.
- − The date is missing the apostrophe in 'TODAY'S' compared to the header text.
Stable Diffusion 3.5 Medium
- + Features decorative chalk borders and flourishes.
- + Maintains a consistent, though illegible, artistic style across the board.
- − Severe spelling errors and garbled text make the menu mostly unreadable.
- − Failed to include the specific date correctly ('APRIL $0624' instead of 'APRIL 30, 2026').
- − Failed to render the specific menu items requested.
Verdict: Seedream 4.0 significantly outperforms Stable Diffusion 3.5 Medium by producing perfectly legible and accurate text that follows every detail of the prompt. While Stable Diffusion 3.5 Medium struggles with typography and basic spelling, Seedream 4.0 creates a highly realistic chalk menu that would be believable in a real-world setting.
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 Medium
AI Judge Analysis
Seedream 4.0
- + Excellent high-detail rendering of the spacesuit and horse's fur.
- + Dynamic, cinematic composition with a striking nebula in the background.
- + Clean lighting and realistic textures throughout the image.
- − Failed the specific spatial instruction; the astronaut is riding the horse.
- − The horse's front legs exhibit anatomical distortion or merging.
Stable Diffusion 3.5 Medium
- + Successfully placed the horse on top of the astronaut (albeit strangely merged) in response to the specific instruction.
- + Good wide-angle composition showing the curvature of the earth.
- − Significant anatomical errors with five spindly legs on the horse.
- − Low-quality rendering of the astronaut's face/visor and legs.
- − The 'horse on top' instruction resulted in a messy, non-surreal blending of bodies.
Verdict: While Seedream 4.0 failed the specific spatial logic of the prompt (the 'horse on top' instruction), it produced a visually stunning and coherent cinematic image. Stable Diffusion 3.5 Medium attempted to follow the difficult instruction but failed significantly on anatomy, character proportions, and overall image quality. Seedream 4.0 is preferred for its superior aesthetic and professional finish, despite missing the literal prompt inversion.
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 Medium
AI Judge Analysis
Seedream 4.0
- + Excellent photorealism with cinematic lighting and realistic textures.
- + Perfect adherence to the human passenger's bored expression and activity.
- + Accurate positioning of paws on the steering wheel.

- − Composition is slightly cropped from the side.
Stable Diffusion 3.5 Medium
- + High quality detail on the fur and whiskers.
- + Good rendering of a specialized driver's cap with an emblem.
- + Composition places the viewer directly in front of the capybara.
- − Failed the prompt regarding the passenger's activity; she is not looking at a phone.
- − The capybara's anatomy is slightly distorted, looking more like a blend with a beaver or dog.
- − The paws are resting on the dashboard/wheel in a less realistic 'driving' position.
Verdict: Seedream 4.0 followed the prompt instructions much more accurately, particularly regarding the passenger's expression and behavior. Stable Diffusion 3.5 Medium failed to include the phone for the passenger and produced a less convincing 'professional' driving posture for the capybara.
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 Medium

- − Failed to include the requested flag icon.
- − The text 'SUSHI' has a strange artifact or extra dot on the final 'I'.
- − Much less 'miniature diorama' feel compared to the other model, featuring only two basic pieces.
Verdict: Seedream 4.0 followed the prompt significantly better, including the flag icon and producing a more detailed, visually appealing 3D diorama. Stable Diffusion 3.5 Medium produced a much simpler image that missed several specific prompt details and had minor typographic errors.
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 Medium
AI Judge Analysis
Seedream 4.0
- + Perfect inclusion of all four requested animals: puppy, kitten, bunny, and fox.
- + Dynamic and joyful composition that shows the animals actually playing and tumbling.
- + Excellent atmospheric lighting with clear god rays and realistic dew sparkles.
- − The butterfly on the left has slightly awkward wing anatomy.
- − Some of the 'dew' sparkles look more like floating debris or rain in certain areas.
Stable Diffusion 3.5 Medium
- + Crisp and clear rendering of the central animals' faces.
- + Vibrant colors and a clean field of flowers.
- − Failed to include the requested baby bunny.
- − The animals are sitting relatively still, missing the 'tumbling together' action requested.
- − The 'fox' resembles a dog-fox hybrid, and the 'kitten' looks more like a rabbit-cat hybrid.
Verdict: Seedream 4.0 followed the complex prompt much more accurately, including all four specific animals and depicting the playful 'tumbling' action. Stable Diffusion 3.5 Medium missed the bunny entirely and produced more static, posed characters with inconsistent anatomy. Seedream 4.0 also better captured the requested 'god rays' and 'dew' effects, resulting in a more magical and cohesive scene.
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 Medium
AI Judge Analysis
Seedream 4.0
- + Excellent text rendering with correct spelling and accents.
- + Clean, professional vector-style composition and layout.
- + Highly accurate adherence to the 'Est. 1720' banner requirement.
- − The steam elements are a bit literal and simplistic compared to the rest of the logo.
- − Minimalist style might be a bit too basic for a high-end luxury brand.
Stable Diffusion 3.5 Medium
- + Ornate and very detailed illustrative style which fits the 'Vintage' prompt well.
- + Strong use of warm tones and cross-hatching texture.
- − Significant spelling errors in the brand name ('Florrian') and date ('170').
- − Composition is cluttered and messy, particularly around the bottom ribbons and cup.
- − The 'cloche' is poorly defined and resembles a helmet or cap.
Verdict: Seedream 4.0 followed the prompt perfectly, delivering a clean, usable logo with flawless text rendering and a well-balanced layout. In contrast, Stable Diffusion 3.5 Medium struggled with the typography and basic prompt elements, resulting in spelling errors and a muddled composition that fails as a functional logo.
