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 realism with convincing textures on the wood, book, and glass.
- + Very accurate spatial relationships as the plant is clearly behind and visible through the glass.
- + Natural lighting and reflections on the sphere and table surface.
Nano Banana
- + Clean, minimalist composition with vibrant colors.
- + Captures all requested elements including the soft window light.
- − Physics failure: the blue sphere is floating unnaturally in the center of the cube.
- − The scale of the cube and sphere feels slightly off compared to the table and book.
- − Lack of fine texture detail on the wood compared to Image A.
Verdict: FLUX.2 [dev] Turbo produced a highly photorealistic image with perfect adherence to physics and spatial depth, particularly in how the plant is refracted through the glass. Nano Banana followed the prompt accurately but suffered from a lack of realism, with the sphere floating inside the cube as if it were a solid block of glass or resin rather than a hollow 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 [dev] Turbo
- + Excellent adherence to the 'imperfect framing' prompt with a centered, slightly messy composition typical of candid street photography.
- + Very realistic textures on the man's skin, clothing, and the weathered bicycle.
- + Superior motion blur on the passing cars while maintaining sharp focus on the subject.
- − The front wheel of the bicycle is clipped and seems to clip through the pavement slightly.
- − Some anatomical minor issues with how the hands grip the tools.
Nano Banana
- + Beautiful bokeh and lighting, capturing a more 'cinematic' mood with the lanterns.
- + The wet pavement reflections are more pronounced and visually appealing.
- − The image feels overly stylized and 'too perfect', missing the 'no stylization' and 'imperfect framing' requirements.
- − The bicycle proportions and mechanical details are less realistic than Model A's.
- − The motion blur on the car is less convincing, appearing more like static blur than movement.
Verdict: FLUX.2 [dev] Turbo followed the prompt much more closely, capturing the gritty, candid, and slightly imperfect nature of real street photography. While Nano Banana produced a more traditionally 'beautiful' image with warm lighting, it failed to adhere to the 'no stylization' and 'imperfect framing' instructions, looking more like a staged movie still than a candid photo.
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.”
AI Judge Analysis
FLUX.2 [dev] Turbo
- + Excellent depiction of small beads in the braids
- + High realism in facial textures, skin pores, and wet-looking scars
- + Sophisticated use of lighting and atmospheric bokeh sparks
- − The torch in the background is slightly blurry and lacks definition
Nano Banana
- + Strong, heroic facial expression suited for a paladin
- + Clean, ornate engraving on the shoulder plate featuring a griffin
- + Good color contrast with the red cloth underlayer
- − Missed the request for beads in the hair braids
- − The hair and skin have a slightly 'painterly' or CGI look compared to Model A
- − The torchlight reflection feels less integrated into the environment
Verdict: FLUX.2 [dev] Turbo produced a much more photorealistic image that strictly adhered to every detail of the prompt, including the small beads in the hair. While Nano Banana created a compelling character with more stylized armor engravings, it failed to include the requested beads and lacks the lifelike textural depth found in the first image.
Modern Clean Menu

AI Judge Analysis
FLUX.2 [dev] Turbo
- + Excellent photographic quality and food realism.
- + Sophisticated layout that feels like a real commercial design.
- + Bold, readable sans-serif headers and consistent alignment.
- − Nonsense filler text for descriptions and small sub-headers.
- − Section categorization is confusing (putting pizza photos under appetizers).
Nano Banana
- + Strict adherence to the 'grid' request for photos.
- + Vibrant color palette used effectively for accents and borders.
- + More readable text with fewer sheer 'gibberish' characters compared to Model A.
- − Several spelling errors in headers (APPEITIERS, VEGETARIN, MOZZERELLA).
- − Layout is a bit repetitive and lacks the hierarchy of a professional menu.
- − Inconsistent item pricing (e.g., $32 for a lava cake vs $10 later).
Verdict: FLUX.2 [dev] Turbo produces a much higher quality image with realistic food photography and a professional layout, though its categorization of food items is chaotic. Nano Banana follows the grid layout request more literally and has more legible text, but suffers from frequent typos and a less polished aesthetic. FLUX.2 [dev] Turbo is the winner for its superior visual fidelity and professional design sense.
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 PBR materials with realistic subsurface scattering on the fish and detailed rice textures.
- + Perfect text rendering and layout compliance.
- + High-quality lighting and shadows that enhance the 3D diorama effect.
- − The 'JAPAN' text is slightly off-center compared to the diorama.
Nano Banana
- + Good isometric composition and clean, rounded aesthetic.
- + Successfully included more variety of sushi types while remaining clean.
- + Accurate text rendering.
- − The flag is placed to the left rather than below or centered with the text as requested.
- − The materials look more like plastic/clay and lack the 'realistic PBR' quality requested.
- − Shadows are much softer and less defined, reducing the 3D pop.
Verdict: FLUX.2 [dev] Turbo followed the prompt much more effectively, particularly regarding the 'realistic PBR materials' and 'soft refined textures,' resulting in a professional-grade 3D render. Nano Banana produced a nice cartoonish scene, but the textures and lighting are flat, and the text/flag layout did not follow the 'top-center' and 'small flag icon' instruction as precisely as FLUX.
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 fur texture and realistic anatomy for all four animals.
- + Highly dynamic composition with animals appearing to tumble and play as requested.
- + Realistic interaction between the subjects and the dew-sprinkled environment.

- − The rabbit's scale feels a bit small compared to the kitten.
Verdict: FLUX.2 [dev] Turbo produces a much more realistic image with convincing textures and a dynamic, playful composition that feels like a captured moment. Nano Banana excels at the lighting and 'god rays' but suffers from anatomical incoherence in the fox's legs and a more artificial, smoothed-over aesthetic.
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 photographic realism with natural skin textures and lighting.
- + The urban background is very detailed and matches the scale of the character perfectly.
- + The cape's dramatic flow and interaction with the lighting are very cinematic.
- − The fingers on the waist appear slightly elongated and awkwardly positioned.
- − The chest emblem is a bit derivative of the Superman logo rather than a unique design.
Nano Banana
- + Strong, symmetrical composition with clear heroic presence.
- + The character's facial features and short hair are rendered very cleanly.
- + The costume design feels practical and original.
- − The image has a slightly 'digital' or smoothed-over look compared to the requested hyper-photorealism.
- − The lighting on the character feels a bit flat and disconnected from the bright sunset background.
Verdict: FLUX.2 [dev] Turbo achieves a higher level of photorealism with superior texture work and natural lighting integration between the character and the cityscape. Nano Banana has a very clean and aesthetically pleasing composition, but it looks more like high-quality 3D concept art than the requested hyper-photorealistic photo.
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 [dev] Turbo
- + Excellent use of depth and layering with realistic overlapping shadows.
- + Highly detailed organic textures that make the flowers look three-dimensional.
- + Rich, harmonious color palette that feels natural and premium.
- − Slightly heavier and more compact composition compared to a traditional open mandala.
- − Radial symmetry is good but has minor variations in flower orientation.
Nano Banana
- + Perfect geometric radial symmetry with a very clear mandala structure.
- + Excellent variety of distinct elements including sliced citrus, seeds, and ferns.
- + High level of clarity and sharpness across all the small components.
- − The lighting is very flat, making it look a bit like a graphic design rather than a physical arrangement.
- − The background texture is somewhat repetitive and lacks natural depth.
Verdict: Both models followed the prompt exceptionally well, but they offer different aesthetics. FLUX.2 [dev] Turbo provides a lush, painterly, and photorealistic image with deep shadows and beautiful textures, while Nano Banana provides a cleaner, more geometrically precise mandala with a diverse range of identifiable fruits and seeds. FLUX.2 [dev] Turbo is the winner for its superior lighting and realistic organic feel.
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 typography including the grave accent in 'Caffè'
- + Excellent use of texture to create an authentic vintage parchment feel
- + Strong vector emblem composition with a well-rendered banner
- − The steam rising from the cloche is slightly simplistic compared to the rest of the illustration
Nano Banana
- + Clean circular emblem layout and consistent warm brown tones
- + Unique interpretation with steam coming from inside the cloche
- − Missed the grave accent on 'Caffè'
- − The cloche handle looks like a simple ring, lacking the 'dome' weight requested
- − Minimal texture compared to the 'subtle texture' requested in the prompt
Verdict: FLUX.2 [dev] Turbo followed the prompt with high precision, accurately rendering the text and the requested 'vintage texture' on a light background. Nano Banana produced a clean logo, but failed on the specific typography (the accent in Caffè) and provided a much flatter image that lacked the 'vintage' grit requested.
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.
