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]
- + Perfect adherence to all spatial relationships in the prompt
- + Clean, high-quality aesthetic with modern lighting
- + Accurate glass reflections and refractive effects
- − The sphere appears slightly large relative to the 'small' descriptor in the prompt
Nano Banana 2
- + Excellent text rendering on the book spine

Verdict: Both models did an excellent job of combining two source images into a new scenery. Nano Banana 2 is the winner due to its much more dynamic and visually appealing composition, featuring a classic winding coastal road and better lighting integration, whereas FLUX.2 [flex] feels a bit more like a simple background swap.
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]
- + Clean, minimalist layout with plenty of white space.
- + Correct inclusion of specified sections: Appetizers, Pizza, and Mains.
- + Good use of color blocking for category headers.
- − Text is mostly gibberish or contains significant spelling errors.
- − Food photos in the grid are repetitive and don't match the category labels (e.g., steaks under appetizers).
- − Layout is somewhat rigid and less visually engaging than the competitor.
Nano Banana 2
- + Excellent text rendering with legible, realistic food names and descriptions.
- + Logical association between food photos and the corresponding menu items.
- + Professional font choices and clear hierarchical layout.
- − Small artifacts in the smaller text descriptions upon close inspection.
- − Complexity is slightly higher than 'minimalist', though it fits 'casual dining' perfectly.
Verdict: Nano Banana 2 is the clear winner as it produces a fully functional menu with legible, correctly spelled text and relevant food imagery. While FLUX.2 [flex] follows the layout prompt, its inability to generate coherent text and its mismatched food photos make it an inferior design tool for this task.
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

Verdict: FLUX.2 [flex] produces a much more aesthetically pleasing and high-resolution image with beautiful lighting, though it fails significantly on the technical logic of the bicycle. Nano Banana 2 better understands the 'candid street photo' aesthetic and framing, but suffers from significant AI artifacts in the hands and tools. FLUX.2 [flex] is the winner for its superior realism and texture, despite the structural errors in the background objects.
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 adherence to text placement and hierarchy
- + Excellent clay-like cartoon 3D aesthetic with soft textures

- + Incredible detail in the food textures (rice, roe, fish)
- + High-quality PBR material rendering for the wood and ceramics
- + Consistent isometric perspective
- − Failed to place 'SUSHI' below 'JAPAN' as requested
- − Composition is much more cluttered than the 'minimal' request
Verdict: FLUX.2 [flex] followed the layout and text instructions perfectly, delivering the exact 'cartoon miniature' aesthetic requested. While Nano Banana 2 produced much more realistic and appetizing textures, it failed the specific text arrangement and ignored the 'minimal' constraint, resulting in a cluttered scene.
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 source preservation, maintaining the layout of the town and mountain perfectly.

Verdict: Both models did an excellent job of preserving the composition and detail of the source image while changing the lighting. Nano Banana 2 is the winner because its interpretation of the 'glistening stars' is much more detailed and visually stunning, featuring a realistic star field that fits the alpine setting perfectly. FLUX.2 [flex] has a much emptier sky with less realistic star rendering.
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 depiction of god rays and morning atmospheric mist.
- + High-quality fur texture and realistic anatomy for all four animals.
