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 [dev] Turbo
- + Excellent photographic realism with realistic glass textures and dust particles.
- + Accurate physical rendering of reflections and shadows.
- + Superior book detail, including visible spine text and realistic paper texture.
- − The glass box has an open front/side which contradicts the concept of a closed 'cube' containing an object.
Seedream 4.0
- + Perfect adherence to the spatial 'cube' geometry with all sides closed.
- + Dynamic lighting and caustic effects on the table surface.
- + Clean, vibrant colors that match the prompt exactly.
- − The plant visibility through the glass is slightly muddy/blurry compared to the rest of the scene.
- − Slightly less detailed book texture than the competitor.
Verdict: Both models followed the complex spatial instructions perfectly. FLUX.2 [dev] Turbo offers a much more realistic, high-fidelity photographic look with intricate details on the book and table. However, Seedream 4.0 is the winner as it successfully rendered a closed glass cube, whereas FLUX.2 rendered an open-ended glass container, and Seedream's lighting effects on the wooden table are more visually striking.
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 [dev] Turbo
- + Excellent adherence to all prompt elements including light rain and motion blur.
- + Superior skin texture and high-fidelity details on the man's face and hands.
- + Strong use of reflections on the wet pavement.
- − The bike's handlebars and front wheel geometry are slightly distorted.
- − The man's right arm appears to merge awkwardly with the bicycle frame.
Seedream 4.0
- + Natural composition and believable candid street atmosphere.
- + Good execution of the red bicycle color and general reflections.
- + Motion blur on the passing vehicle is well rendered.
- − Image is noticeably softer/blurrier across the subject compared to the other model.
- − The mechanical details of the bicycle, specifically the chain and pedal area, are physically nonsensical.
- − The facial details are significantly lower quality than the competitor.
Verdict: FLUX.2 [dev] Turbo followed the prompt much more effectively, specifically capturing the skin textures and the fine details of the light rain. While Seedream 4.0 provided a nice composition, it suffered from a lack of sharpness and significant structural errors in the bicycle's anatomy. FLUX.2's output is much more cinematic and high-resolution, making it the clear winner.
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 [dev] Turbo
- + Excellent layout that looks like a realistic professional menu.
- + High text legibility and mostly coherent English headings.
- + Clearly defined sections for appetizers, pizza, and mains as requested.
- − Some placeholder text and pricing logic is slightly nonsensical ($250 for a pizza).
Seedream 4.0
- + Features large, appetizing food photography.
- + Follows the white background and bold sans-serif font requirements.
- − Lacks an actual menu structure; there are no item names or prices.
- − The grid layout is messy with awkward white space.
- − Missed the 'professional layout' aspect of the prompt.
Verdict: FLUX.2 [dev] Turbo successfully created a functional and aesthetically pleasing menu design with clear columns, pricing, and organized sections. Seedream 4.0 provided good quality images but failed to arrange them into an actual menu format, resulting in a disorganized collage rather than a professional document.
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 [dev] Turbo
- + Excellent text rendering with clean, professional typography.
- + Very high-quality PBR material rendering, especially on the salmon and rice textures.
- + Perfect adherence to the 'diorama base' and 'isometric' perspective requirements.

Seedream 4.0
- + Captures the '3D cartoon' style very effectively with soft, rounded shapes.
- + Accurate text and icon placement.
- + Good variety of sushi types within the miniature scene.
- − The text is slightly less crisp than Model A.
- − Lighting is a bit flatter, losing some of the 'refined texture' feel requested.

Verdict: Both models followed the prompt exceptionally well, including the specific text and flag requirements. FLUX.2 [dev] Turbo produced a higher fidelity image with superior material textures and cleaner typography, while Seedream 4.0 leaned more into the 'cartoon' aesthetic with a wider variety of sushi models. FLUX.2 [dev] Turbo is the winner for its professional finish and more convincing 3D diorama presentation.
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 [dev] Turbo
- + Excellent prompt adherence, correctly featuring all four requested animals with distinct characteristics.
- + Very high detail in fur texture and expressive facial features.
- + Superior background integration with beautiful god rays and realistic dew sparkles.
- − The kitten has an anatomical oddity with a fifth leg/paw visible near the fox's head.
- − Slightly over-sharpened look on certain flowers.
Seedream 4.0
- + Strong dynamic composition with animals appearing more 'in motion' chasing the butterflies.
- + Beautiful lighting effects with bright, atmospheric golden hour bokeh.
- − The fox kit's anatomy is slightly distorted with a very elongated and awkwardly placed neck/chest area.
- − The dew/sparkle effects look like floating white blobs rather than realistic water droplets.
- − Finer details like the kitten's eyes are a bit less refined compared to the other model.
Verdict: FLUX.2 [dev] Turbo produced a more technically detailed image with better fur texture and environment rendering, though it suffered from a minor limb artifact. Seedream 4.0 captured the 'tumbling' motion and joyful vibe more effectively, but fell short in anatomical accuracy and realism of the dew effects. FLUX.2 [dev] Turbo is the preferred choice for its superior clarity and adherence to the 'hyper-photorealistic' part of the prompt.
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 [dev] Turbo
- + Excellent skin texture and hyper-realistic facial details
- + Accurate representation of short hair blowing in the wind
- + Superior lighting and color balance for a golden sunset
- − The hands on the hips have slight anatomical warping in the fingers
- − The cape appears to grow out of the shoulders and hair somewhat unnaturally
Seedream 4.0
- + Strong composition with a clear 'hero' stance and dynamic cape billowing
- + Good rendering of the New York cityscape and Empire State Building
- + Captures the sunset atmosphere well with rim lighting on the suit
- − Missed the 'gloves' requirement in the prompt
- − The facial features are less detailed and have a slightly blurry, AI-typical look
- − Anatomical issues where the thumb on the left hip is missing or merged
Verdict: FLUX.2 [dev] Turbo produces a much more realistic and high-fidelity image, particularly in the face and fabric textures. While both models struggled with perfect hand anatomy, FLUX.2 followed the prompt more closely by including the requested gloves, whereas Seedream 4.0 left them out and had a softer, less detailed finish.
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 [dev] Turbo
- + Perfect adherence to all text requirements including the grave accent on 'Caffè'.
- + Excellent vector emblem style with balanced, professional composition.
- + Subtle, realistic parchment texture that enhances the vintage feel.
- − The steam lines are slightly disconnected from the cloche.
Seedream 4.0
- + Strong 'vintage' color palette and clean typography.
- + Good illustration of the cloche dome with highlights and shadows.
- + Accurate text rendering for both the name and the date.
- − Missing the grave accent on 'Caffè'.
- − The banner construction is slightly awkward with the ribbon ends disconnected from the main scroll.
- − The steam looks a bit more like generic smoke than steam.
Verdict: FLUX.2 [dev] Turbo followed the prompt more precisely, specifically including the correct accent mark on 'Caffè' and creating a more cohesive banner design. While Seedream 4.0 produced a high-quality vintage graphic, it missed the linguistic detail and had slight structural issues in the banner execution.
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
FLUX.2 [dev] Turbo
- + Excellent text rendering with almost perfect spelling and labels.
- + Highly detailed illustrations of the Saturn V and Lunar Module.
- + Includes professional design touches like crew silhouettes and a NASA-inspired layout.
- − Confusing visual flow with repetitive icons for 'Translunar' and 'Earth Orbit'.
- − Literal interpretation of the prompt led to 'Saturn Vicon' being written as text instead of just showing the icon.
Seedream 4.0
- + Very clear linear progression that follows the requested numerical steps 1-6.
- + Clean, minimalist vector style that adheres well to 'flat-vector style' with crisp lines.
- + Strong adherence to the requested color palette.
- − Text rendering is slightly inconsistent, with some 's' characters appearing distorted.
- − Missing icons for the final two steps (Descent and Landing), using a single image for both.
Verdict: FLUX.2 [dev] Turbo produced much higher quality individual icons and superior text rendering, though the overall layout is cluttered and logically recursive. Seedream 4.0 followed the structural instructions for a step-by-step infographic much better with a clear linear flow, but it failed to provide unique icons for the final stages and had lower-quality text. FLUX.2 is the prefered choice for its professional aesthetic and detail despite the layout messiness.
