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
FLUX.2 [max]
- + Perfect adherence to the spatial arrangement requested, with the book sitting on top of the cube.
- + Excellent realism in textures, particularly the leather-bound book and the glass refractive properties.
- + Soft lighting correctly interacts with the glass, creating realistic internal reflections and shadows on the table.
- − The plant in the background is quite blurred, making it slightly less distinct as being 'behind' the glass.
Stable Diffusion 3.5 Large
- + Accurate rendering of the requested elements including the blue sphere and wooden table.
- + The plant is clearly visible through the glass as requested.
- − Failed the spatial instruction 'On top of the cube sits a red book'; instead, it placed the cube on top of the book.
- − The lighting is somewhat harsh and inconsistent with 'soft window light'.
- − Visible artifacts on the edges of the glass cube where it meets the book.
Verdict: FLUX.2 [max] followed the complex spatial instructions perfectly, placing the red book on top of the glass cube and the sphere inside. Stable Diffusion 3.5 Large reversed the order of the cube and the book, which also resulted in the sphere appearing to float or sit on the book rather than being inside the cube.
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
FLUX.2 [max]
- + Excellent skin texture and realistic age details on the hands and face.
- + Perfect adherence to the shallow depth of field and motion blur requirements.
- + Highly realistic bicycle anatomy and wet pavement reflections.
- − The 'imperfect framing' request is subtle, as the composition feels quite professionally balanced.
Stable Diffusion 3.5 Large
- + Includes a bus and car in the background to establish the street scene.
- + Good color contrast with the red bicycle against the cool tones.
- − The man's hands are fused into a singular mass of flesh, lacking fingers.
- − The bicycle frame geometry is illogical and broken near the pedals.
- − The rain effect looks like a digital overlay rather than an environmental element.
Verdict: FLUX.2 [max] produced a nearly photorealistic image that perfectly captured the technical requirements like 50mm lens feel, motion blur, and natural skin textures. Stable Diffusion 3.5 Large struggled significantly with anatomical correctness, resulting in deformed hands and a structurally unsound bicycle, while also failing to match the level of photographic realism requested.
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
FLUX.2 [max]
- + Excellent adherence to all required sections (Appetizers/Pizza/Mains).
- + Clean, professional layout that genuinely looks like a usable restaurant menu.
- + Higher text legibility and better organization of price points.
- − Small spelling artifacts in item descriptions.
- − The food photos on the left are a vertical column rather than a full grid across the page.
Stable Diffusion 3.5 Large
- + High-quality, vibrant food photography in a clear grid layout.
- + Bold, modern sans-serif typography for the main headers.
- − Poor text rendering for smaller details, resulting in illegible 'garbled' characters.
- − Layout is less practical for a menu, with sections compressed into a narrow center column.
- − Misspelled key headers (e.g., 'MAIMAES' instead of Mains, 'APPETIZRS').
Verdict: FLUX.2 [max] is the superior choice because it produces a functional, logical menu layout that correctly incorporates all requested sections with professional spacing. In contrast, Stable Diffusion 3.5 Large creates a visually striking grid but fails significantly on text legibility and logical structure, making the menu unusable.
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
FLUX.2 [max]
- + Perfectly followed layout instructions with text at the top-center and a solid light blue background.
- + The 45-degree isometric perspective is precise and clean.
- + Exceptional minimalist 3D rendering with soft, refined textures and realistic lighting.
- − The sushi variety is a bit simple compared to the other model.
Stable Diffusion 3.5 Large
- + High level of detail in the sushi models, specifically the rice grain textures.
- + Vibrant and appealing color palette.
- − Failed to place text at the top-center, instead attaching it to a flag within the scene.
- − Ignored the 'minimal garnish' instruction, creating a cluttered compositions with many decorative elements.
- − Background has a slight gradient/shadow rather than being a solid color.
Verdict: FLUX.2 [max] followed every aspect of the prompt, including the specific text placement, isometric angle, and minimalist aesthetic. In contrast, Stable Diffusion 3.5 Large produced a much more cluttered scene that integrated the text into the objects rather than placing it as an overlay, and it largely ignored the request for a 'minimal' diorama.
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
FLUX.2 [max]
- + Perfect adherence to all four requested animal species (golden retriever, tabby kitten, bunny, red fox).
- + Ultra-detailed fur textures and anatomy, particularly on the fox's tail and the kitten's paws.
- + Balanced composition with clear separation between the subjects and the environment.
- − The lighting, while warm, lacks the explicit 'god rays' effect requested in the prompt.
- − The kitten is significantly smaller than the bunny, which looks slightly out of scale.
Stable Diffusion 3.5 Large
- + Excellent capture of the 'joyful' vibe with more expressive, smiling faces on the puppy and fox.
- + Stronger interpretation of the golden sunrise and 'god rays' lighting effects.
- + Good sense of motion and action with the animals running toward the camera.
- − Incomplete prompt adherence; it missed the 'tabby kitten' and replaced it with a generic ginger feline.
- − Noticeable anatomical artifacts, such as the fox kit's lack of distinctive black paws and the puppy's front left leg looking slightly mangled.
- − Heavy bokeh/blur makes some of the butterflies and background elements look messy.
Verdict: FLUX.2 [max] is the winner due to its superior anatomical accuracy and strict adherence to the requested animal list, including the specific tabby markings and fox features. While Stable Diffusion 3.5 Large captured a more energetic and well-lit 'joyful' atmosphere, it failed to render a tabby kitten and suffered from blurred details and slight anatomical distortions.
Victorian Greenhouse Oasis
Text-to-Image“Hyper-photorealistic interior of a lush Victorian glass greenhouse filled with exotic tropical plants, vibrant blooming orchids, tall ferns, colorful butterflies in flight, sunlight filtering through ornate glass roof creating realistic caustics and dew on leaves, intricate iron framework visible, misty atmosphere, 8K masterpiece.”
AI Judge Analysis
FLUX.2 [max]
- + Excellent adherence to the request for 'vibrant blooming orchids' in multiple colors.
- + Superior atmospheric lighting with clear god rays and light particles.
- + Highly detailed Victorian ironwork and integrated seating that enhances the composition.
- − The butterflies look a bit like stickers placed on top of the image rather than being part of the 3D space.
- − Slightly oversaturated colors compared to a truly photorealistic look.
Stable Diffusion 3.5 Large
- + More realistic misty atmosphere and lighting integration.
- + Architectural design feels more authentic to a historic Gothic-Victorian greenhouse.
- + Butterflies are better integrated into the depth of the scene.
- − The orchid blooms look slightly artificial or plasticky upon close inspection.
- − Fewer 'vibrant' floral details compared to the other model, focusing more on green foliage.
- − The lighting is somewhat washed out in the center.
Verdict: FLUX.2 [max] produced a much more lush and vibrant image that explicitly followed the floral requirements of the prompt, creating a stunning visual with intricate ironwork and varied orchids. Stable Diffusion 3.5 Large handled the 'misty atmosphere' and depth of the butterflies more naturally, but it lacked the punch and rich detail found in the FLUX.2 [max] interior.
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
FLUX.2 [max]
- + Perfectly captures the 'hands on hips' pose requested in the prompt.
- + Excellent fabric textures and suit material with realistic lighting interaction.
- + Dynamic and balanced composition using the city layout to draw the eye.
- − The chest emblem is a bit abstract and lacks a clear iconic design.
Stable Diffusion 3.5 Large
- + Beautiful golden hour lighting with a strong hazy atmosphere.
- + Sharp and detailed city background with recognizable landmarks like the Empire State Building.
- + The cape physics look very natural and dramatically billowed.
- − Failed to follow the specific 'hands on hips' instruction, opting for arms at the side.
- − The character's head and neck integration looks slightly stiff and less natural than Model A.
Verdict: FLUX.2 [max] is the winner because it adhered much more closely to the specific pose requested in the prompt while maintaining a more professional cinematic composition. While Stable Diffusion 3.5 Large produced a beautiful sunset atmosphere, it missed the key 'hands on hips' instructional detail and the character integration feels slightly more artificial.
Intricate Floral Mandala
Text-to-Image“Perfectly symmetrical mandala made entirely of real flowers, petals, leaves, fruits, and seeds in vibrant natural colors, intricate layered patterns with radial symmetry, top-down view on a soft neutral background, hyper-detailed organic textures and subtle shadows, photorealistic, 8K masterpiece.”
AI Judge Analysis
FLUX.2 [max]
- + Exceptional photorealistic textures and organic lighting.
- + Highly complex and layered arrangement of realistic organic matter.
- + Follows the 'top-down view' and 'soft neutral background' instructions perfectly.
- − The overall color palette is slightly muted compared to the 'vibrant' request.
Stable Diffusion 3.5 Large
- + Bright, vibrant colors that pop against the background.
- + Very clean and clear radial symmetry.
- + Includes a wide variety of distinct fruits and seeds.
- − Looks more like a digital illustration or 3D render than 'real' photorealistic organic objects.
- − The central flower and petals have a plastic-like, artificial sheen.
Verdict: FLUX.2 [max] significantly outperforms Stable Diffusion 3.5 Large by capturing the 'real' and 'photorealistic' aspects of the prompt; it looks like a genuine physical arrangement of botanical elements. While Stable Diffusion 3.5 Large is more vibrant, it has an artificial, CGI quality that ignores the request for natural textures and photorealism.
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
FLUX.2 [max]
- + Perfect text rendering for both name and date banner
- + Clean, balanced vector emblem composition
- + Excellent adherence to the vintage minimalist aesthetic
- − The steam lines are very thin compared to the rest of the illustration
Stable Diffusion 3.5 Large
- + Nice use of negative space in the cloche design
- + Adds decorative corner flourishes to the background
- − Misspelled the name as 'Cafféé Florian' with an extra 'e'
- − The cloche is disconnected and floating awkwardly
- − The steam coming from the top of the dome is illogical
Verdict: FLUX.2 [max] significantly outperformed Stable Diffusion 3.5 Large by correctly spelling 'Caffè Florian' and creating a cohesive, professional vector emblem. Stable Diffusion 3.5 Large suffered from typographical errors and a disjointed illustration where the cloche lid floats above the base with no clear connection.
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
