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]
- + Excellent depiction of thick glass and optical distortion
- + Accurate soft lighting from the left
- + Simple, clean composition that adheres to all prompt elements
- − The blue sphere appears to be floating mid-air inside the cube
- − The plant in the background is quite blurry and less defined
Nano Banana 2
- + Perfect text rendering on the book spine
- + Realistic wood texture on the table
- + Includes a clear reflection of the sphere on the bottom glass surface
- − The glass cube is missing a front pane, looking more like an open frame than a solid cube
- − The sphere appears slightly too large relative to the 'small' descriptor
Verdict: FLUX.2 [dev] followed the spatial instructions perfectly, creating a convincing solid glass cube with accurate refraction, though the sphere appears to float. Nano Banana 2 produced an image with impressive details like legible text and rich textures, but it failed the geometric prompt by rendering an open-faced glass frame rather than a closed 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]
- + Excellent depiction of motion blur from passing cars
- + Strong interpretation of the 'imperfect framing' prompt with a tight, slightly off-center composition
- + High-quality skin textures and realistic lighting
- − The red bicycle construction is physically nonsensical with multiple stems and overlapping frames
- − The man's scale relative to the bike and road feels slightly inconsistent
Nano Banana 2
- + Beautiful atmospheric depth with neon signs and wet pavement reflections
- + The action of repairing the bike (with a wrench and tool kit) is much more logically depicted
- + Exceptional color palette and 'candid' street photography aesthetic
- − Failed to include the requested motion blur for passing cars
- − The wrench and chain interaction is slightly messy upon close inspection
Verdict: Nano Banana 2 produces a much more coherent and visually appealing image that captures the 'Japanese street' atmosphere perfectly, although it failed the specific instruction for motion blur. FLUX.2 [dev] followed the motion blur and framing prompts more techincally, but the central subject—the bicycle—is a distorted mess of overlapping metal parts that ruins the realism.
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]
- + Excellent depiction of shallow depth of field and bokeh sparks
- + High-quality skin texture with realistic scars and dirt
- + Clear lighting logic with warm torchlight reflecting off the metal
- − The 'beads' in the hair look a bit repetitive and simplistic
Nano Banana 2
- + Incredibly intricate engraving on the armor including runes and heraldry
- + Strong atmospheric composition with visible sword and textured clothing
- + Distinctive braided hair with detailed metallic beads
- − Slightly less 'shallow' depth of field compared to the prompt's request
Verdict: Both models followed the prompt exceptionally well. FLUX.2 [dev] excels in photographic realism, specifically with the bokeh effects and natural skin texture. However, Nano Banana 2 provides a more 'paladin-like' feel with superior armor detail and a grittier, more battle-worn aesthetic, making it the more visually compelling interpretation of the prompt's creative elements.
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]
- + Excellent fur texture and lighting on the animals.
- + Captures the 'god rays' and dew sparkles effectively.
- + Very high resolution and clear focal points on the faces.
- − The animals are mostly sitting rather than 'playfully chasing and tumbling'.
- − Generated two bunnies instead of the requested one.
Nano Banana 2
- + Captures the 'playfully chasing' action much better than Model A.
- + Adheres strictly to the requested animal count (one of each).
- + Lush wildflower meadow is more varied and colorful.
- − The fox kit's front legs look slightly unnatural in their pose.
- − Overall sharpness is slightly lower than Model A, particularly in the background.
Verdict: Nano Banana 2 followed the prompt's instructions regarding the action and animal count much more accurately, showing the animals in motion rather than sitting. While FLUX.2 [dev] has slightly superior fur texture and lighting, it failed the count (two bunnies) and the requested activity of 'tumbling together'.
