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 [flex]
- + Clean, modern aesthetic with high clarity in the glass reflections.
- + The blue sphere is perfectly centered and rendered with smooth textures.
- + Lighting is soft and follows the 'from the left' instruction accurately.
- − The sphere appears relatively large, pushing the definition of 'small'.
- − The glass cube lacks a physical top surface under the book, making the book appear to float on the edges.
Nano Banana Pro
- + Excellent adherence to the 'small' scale for the blue sphere.
- + High level of realism in textures, particularly the weathered wooden table and the vintage book.
- + Accurately renders the plant through the glass with realistic distortion and smudging on the glass surface.
- − The lighting from the window is quite harsh rather than 'soft'.
- − The plant is more besides the cube than 'behind' it, though still visible through the glass.
Verdict: Both models followed the prompt instructions very well, but Gemini 3 Pro Image Preview stands out for its superior realism and more accurate interpretation of 'small' regarding the sphere. FLUX.2 [flex] produced a very clean, digital-looking image, but Gemini 3 Pro Image Preview captured the atmospheric details of the glass and wooden textures more convincingly.
Man and Car in California
Editing“Make a photo of the man driving the car down the California coastline”
AI Judge Analysis
FLUX.2 [flex]
- + Near-perfect preservation of the car's exterior design, including the distinctive grille and headlights.
- + Successfully placed the subject from the reference photo into the driver's seat with matching hair.
- + The motion blur on the wheels and road creates a convincing sense of realistic action.
- − The subject's clothing was changed from a heavy plaid coat/scarf to a light summer shirt.
- − The character's facial likeness is slightly generic compared to the second source image.
Nano Banana Pro
- + Excellent preservation of the subject's specific outfit, including the heavy scarf and plaid coat from the source image.
- + The face and smile are a much more accurate match to the source character in the second image.
- + Better composition that emphasizes the coastline scenery while maintaining a high level of detail in the car interior.
- − The car's perspective and scale feel slightly distorted compared to the original car reference.
- − The driver's position (on the left side) contradicts the Rolls-Royce's dashboard layout shown in the original photo, which appeared to be a RHD or centered luxury interior.
Verdict: Both models handled this complex multi-image edit well, but Gemini 3 Pro Image Preview is the winner for its superior source preservation of the person's identity and specific clothing. While FLUX.2 [flex] maintained the car's exterior details more accurately, Gemini 3 Pro created a more emotionally resonant and character-accurate scene that felt like a direct continuation of both source images.
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 [flex]
- + Excellent adherence to technical prompts like motion blur and shallow depth of field.
- + High-quality skin texture and realistic, candid composition.
- + Strong cinematic lighting and reflections on the pavement.
- − The red bicycle frame has some structural inconsistencies, such as the missing top tube and floating chain elements.
Nano Banana Pro
- + Captures a very authentic, 'no stylization' film aesthetic that looks like a real 35mm street photo.
- + The bicycle design is highly realistic and appropriate for a Japanese street scene.
- + Excellent environmental storytelling with the taxi and background pedestrians.
- − Fails to include the requested motion blur from passing cars.
- − The depth of field is deeper than the requested 'shallow depth of field' associated with a 50mm lens.
Verdict: FLUX.2 [flex] followed more of the technical prompt requirements, specifically the motion blur and the shallow depth of field, resulting in a more cinematic image. However, Gemini 3 Pro Image Preview achieved a much more convincing 'no stylization' look, appearing like a genuine vintage photograph with a more realistic bicycle and environment. FLUX.2 is the winner for better prompt adherence regarding specific camera effects.
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 [flex]
- + Perfect grid alignment and consistent color coding between headers and photos.
- + Extremely clean, minimalist aesthetic suitable for a professional menu.
- + The food photos look highly appetizing and professional.
- − The text is largely gibberish and lacks legibility in the smaller descriptions.
- − Item prices are somewhat inconsistently spaced.
Nano Banana Pro
- + Includes more legible and realistic-looking text for menu items and descriptions.
- + Creative use of geometric accents adds a playful modern feel.
- + The 2x3 grid variety of food matches the different categories better (bruschetta for appetizers, burgers for mains).
- − Repeats the same item name multiple times (e.g., 'Bruschetta' four times) in the list.
- − Composition feels slightly more cluttered compared to the minimalist goal.
Verdict: Both models followed the prompt well, but FLUX.2 [flex] achieved a much more professional and realistic graphic design layout that looks like a high-end minimalist menu. Gemini 3 Pro Image Preview handled the text content better and included more logical food variety for the sections, but the layout is slightly less polished than FLUX.2 [flex].
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 [flex]
- + Perfect text rendering of 'JAPAN' and 'SUSHI'
- + Accurate and centered Japanese flag icon
- + True solid light blue background with smooth isometric base
- − The textures look a bit too clay-like or plastic rather than realistic PBR
- − Very simple sushi models compared to the competitor
Nano Banana Pro
- + Excellent miniature diorama aesthetic with wood and moss textures
- + Higher detail on the sushi pieces and materials (PBR effect is stronger)
- + More creative diorama base with cherry blossom accents
- − The flag icon is stylized/distorted rather than a standard flag
- − The text layout is slightly off-center and not perfectly 'top-center' as requested
Verdict: FLUX.2 [flex] adhered much better to the specific layout and text instructions, providing a clean, professional-looking graphic with a perfect flag icon. Gemini 3 Pro Image Preview created a more visually impressive and detailed 3D miniature scene with better textures, but failed to follow the specific text placement and flag icon requirements as precisely.
Night Sky Transformation
Editing“Change the scene to night: a deep, dark sky with subtle, glistening stars visible behind the mountain.”
AI Judge Analysis
FLUX.2 [flex]
- + Excellent preservation of the source image's geometry and composition.
- + Natural-looking light bloom effect on the mountain peak.
- − Very few stars are visible despite the prompt's request.
- − The sky appears more like a twilight/deep blue rather than a 'dark sky'.
Nano Banana Pro
- + Strong adherence to the 'glistening stars' instruction with a dense, detailed night sky.
- + Correctly darkens the sky to a deep, nighttime black/purple.
- + Perfect preservation of the landscape and village from the source image.
- − The lighting on the mountain peak is slightly flatter compared to Model A.
Verdict: Both models did an excellent job of preserving the original landscape and village. Gemini 3 Pro Image Preview is the winner as it much more accurately followed the prompt's request for a dark sky and glistening stars, whereas FLUX.2 [flex] produced a very sparse star field.
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 [flex]
- + Excellent photographic quality with naturalistic lighting and depth of field.
- + Impressive detail in the fur texture and dew drops on the grass.
- + Includes all four requested animals with anatomical accuracy.
- − The animals are largely static and posing rather than 'tumbling' or 'chasing' as requested.
- − The fox's paw placement on the rabbit looks slightly stiff.
Nano Banana Pro
- + Perfectly captures the 'tumbling' and 'chasing' action requested in the prompt.
- + Very expressive faces on all animals, enhancing the 'joyful vibe'.
- + Dynamic composition that feels more alive and playful.
- − The image has a slightly more 'digital art' or 'CGI' feel rather than 'hyper-photorealistic'.
- − The kitten is disproportionately small and lacks some of the fine detail seen in the other animals.
Verdict: While FLUX.2 [flex] produces a more realistic and technically detailed photographic image, Gemini 3 Pro Image Preview captures the requested action and mood much better. Gemini 3 Pro shows the animals actually playing and running through the meadow, whereas FLUX.2 presents a beautiful but static portrait of them sitting together.
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 [flex]
- + Excellent depiction of the ornate Victorian ironwork and glass roof structure.
- + Rich, saturated colors in the vibrant orchids and butterflies.
- + Clear composition with a central path leading the eye through the scene.
- − The misty atmosphere feels somewhat flat compared to the other model.
- − Caustics and dew effects are subtle and less pronounced than requested.
Nano Banana Pro
- + Superb atmospheric lighting with realistic misty haze and light god rays.
- + Captures the 'exotic tropical' feel better with hanging plants and diverse textures.
- + Visible dew on the leaves and more intricate glass reflections.
- − Some butterflies appear to be floating somewhat unnaturally or merging with the background.
- − The composition is a bit more cluttered, lacking a clear focal point or path.
Verdict: Both models followed the prompt exceptionally well, but Gemini 3 Pro Image Preview provides a more authentic 'misty atmosphere' and better captures the wet, humid feel of a tropical greenhouse with visible dew. FLUX.2 [flex] has a cleaner, more symmetrical composition with beautiful ironwork, but Gemini 3 Pro feels more photorealistic and immersive due to its superior lighting and texture work.
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 [flex]
- + Perfectly follows the requested 'hands on hips' pose and full-body framing.
- + Superior suit texture and lighting integration on the character.
- + Stronger, more determined heroic expression as requested.
- − The background buildings are slightly less distinct compared to the foreground sharpness.
Nano Banana Pro
- + Excellent urban cityscape with recognizable landmarks like the Empire State Building.
- + Realistic dust/debris particles caught in the low sunlight on the rooftop.
- − Failed to follow the 'hands on hips' pose request.
- − The suit design feels slightly more generic and the 'H' emblem is a bit cliché.
- − Perspective on the rooftop edge where she is standing looks slightly disconnected from her feet.
Verdict: FLUX.2 [flex] followed the prompt instructions much more accurately, specifically capturing the 'hands on hips' pose and the full-body framing. While Gemini 3 Pro Image Preview created a more detailed and atmospheric background, it failed a key instructional element regarding the character's stance.
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 [flex]
- + Clean vector aesthetic that feels modern yet vintage consistent with 'minimalist' prompt.
- + Excellent text rendering with a correct accent mark on 'Caffè'.
- + Balanced composition with clear, sharp lines.
- − The 'Est. 1720' banner is a bit thin/simplistic compared to the main title.
- − The steam is very subtle, almost unnoticeable.
Nano Banana Pro
- + Rich illustrative texture and shading that leans heavily into the vintage 'etched' style.
- + Excellent banner design and more dynamic steam swirls.
- + Stronger 'warm brown' color palette that feels more cohesive.
- − The cloche and banner are slightly off-center compared to the bottom text.
- − Missing the grave accent on the 'e' in 'Caffè', which was correctly included in the prompt.
Verdict: Both models followed the prompt closely, but they interpreted 'vintage' differently. FLUX.2 [flex] produced a clean, minimalist vector logo with perfect typography and spelling, while Gemini 3 Pro Image Preview created a more detailed, hand-drawn illustration with better texture, though it missed the specific accent in the text and had a slightly less balanced composition. FLUX.2 [flex] is the winner for its professional logo execution and exact text accuracy.
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.

- + Perfectly legible and accurate text rendering.
- + Very clean and consistent iconography that fits the flat-vector style.
- − Failed to include the 6th step (Landing) entirely.
- − Missing the required numbering for the steps.
Nano Banana Pro
- + Successfully included all 6 requested steps in a logical flow.
- + High level of creativity with the inclusion of crew name icons and a location pin.
- + Dynamic composition that visually connects the stages of the mission.
- − The text 'TRANSLUNAR TRAJECTORY' has some garbled characters.
- − The style is a bit more illustrative/detailed than the requested 'flat-vector' and 'subtle gradients only' constraints.
Verdict: FLUX.2 [flex] produced a more professional and aesthetically pleasing graphic that perfectly matched the requested style, but it failed to follow the instructions regarding the number of steps and the final 'Landing' icon. Gemini 3 Pro Image Preview captured all instructions, including the mission sequence and specific iconography, making it the more functional infographic despite some minor text artifacts. Gemini 3 Pro is the winner for following the complex structural requirements of the prompt.
