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
- + Perfectly followed spatial instructions with the book clearly on top of the glass cube.
- + Excellent rendering of light refraction and shadows on the wooden surface.
- + Very high photographic realism with convincing textures for the paper and glass.
- − The blue sphere is merged with the bottom edge of the glass cube rather than sitting freely inside.
- − The plant in the background is quite blurry.
Stable Diffusion 3.5 Large
- + The plant is large and clearly visible as requested.
- + The blue sphere is well-rendered and placed centrally.
- + High image clarity and clean composition.
- − Failed spatial instruction: the book is inside/under the cube rather than on top of it.
- − The sphere appears to be floating unnaturally above the book.
- − The glass cube edges look more like plastic/acrylic than glass.
Verdict: Seedream 4.5 adhered much better to the complex spatial prompts, correctly placing the red book on top of the glass cube, whereas Stable Diffusion 3.5 Large placed the book inside. While Stable Diffusion 3.5 Large had a more prominent plant, Seedream 4.5's superior lighting, texture work, and prompt adherence make it the better result.
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
- + Excellent adherence to the 'motion blur from passing cars' prompt element.
- + Very detailed skin texture and fabric realism which matches the cinematic/realistic requirement.
- + Superior depth of field and lighting with realistic wet pavement reflections.
- − Minor anatomical/mechanical issues where the wrench is positioned against the bike chain inconsistently.
- − The bicycle's rear structure is slightly warped near the axle.
Stable Diffusion 3.5 Large
- + Good overall composition and portrayal of the 'light rain' atmosphere.
- + The elderly man's posture feels natural for a candid photo.
- − Failed to include motion blur from passing cars; the vehicles in the background are sharp.
- − The bicycle's front fork and wheel alignment are physically impossible/broken.
- − Skin textures are slightly smoother and less realistic than Model A.
Verdict: Seedream 4.5 is the clear winner as it successfully incorporated every element of the prompt, including the difficult 'motion blur from passing cars' and 'natural skin texture' requests. Stable Diffusion 3.5 Large produced a high-quality image but failed on the motion blur requirement and suffered from significant mechanical artifacts in the bicycle's geometry.
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
- + Strict adherence to all requested sections: Appetizers, Pizza, and Mains.
- + Excellent text legibility and clean sans-serif typography.
- + High-quality food photography that accurately reflects the section headers.
- + Clean, professional minimalist layout with vibrant color-coded accents.
- − Some repetition in the specific names of menu items under the headers.
- − The layout is more of a vertical list than a complex grid.
Stable Diffusion 3.5 Large
- + Creative interpretation of the 'grid' requirement with a gallery-style border.
- + Strong visual appeal and variety in the food photography shown.
- − Poor text rendering with significant gibberish and misspelling in headers (e.g., 'MAIMAES', 'PIZETZA').
- − Failure to clearly delineate the specific requested sections within the text area.
- − Layout feels more like a generic template than a functional menu due to illegible body text.
Verdict: Seedream 4.5 is the clear winner as it produced a functional, professional-looking menu that correctly followed all section requirements (Appetizers, Pizza, Mains) with perfect legibility. While Stable Diffusion 3.5 Large attempted a more ambitious grid composition, the widespread text errors and failure to accurately represent the requested content sections made it less successful for this specific design task.
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 layout adherence with text positioned at the top-center as requested.
- + Very clean and professional 3D render with soft, realistic PBR materials and lighting.
- + Exactly matches the 'minimal garnish' and 'solid background' requirements.
- − The salmon nigiri texture is slightly distorted where it meets the rice.
- − The 'JAPAN' text is simple flat 2D rather than having a 3D effect to match the scene.
Stable Diffusion 3.5 Large
- + High level of detail in the miniature sushi models and textures.
- + Creative 3D implementation of the 'JAPAN SUSHI' text on a sign.
- + Vibrant colors and a high 'toy' aesthetic appeal.
- − Failed the layout instruction to place text at the 'top-center'.
- − The scene is cluttered with many pieces of sushi and garnish, ignoring the 'minimal' request.
- − Text layering issues where 'SUSHI' overlaps the flag pole.
Verdict: Seedream 4.5 followed the complex layout and stylistic constraints much better, delivering a clean, professional-looking diorama with perfectly placed text. While Stable Diffusion 3.5 Large has charming 3D models, it ignored the 'top-center' text placement and the 'minimal' garnish instruction, leading to a cluttered composition.
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.”
