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] Flash
- + Excellent rendering of the glass cube with realistic thickness and edge reflections.
- + The blue sphere has a high-quality, marble-like finish with accurate internal refractions.
- + Very clean, modern photographic aesthetic with soft, natural-looking window light.
- − The plant is slightly less 'behind' the cube compared to Model B, appearing more to the side.
- − The book spine text is nonsensical.
Nano Banana Pro
- + Includes legible text on the book spine ('THE QUIET HOURS').
- + Successfully places the plant directly behind the glass as requested, showing realistic distortion.
- + Beautiful lighting with long shadows that emphasize the table texture.
- − The glass cube is missing its top or front face where the book rests, as the book appears to be floating just above the side walls without a clear glass surface underneath.
- − The base of the blue sphere has a slightly disconnected shadow/reflection.
Verdict: Both models followed the prompt instructions perfectly, including all requested objects and lighting. FLUX.2 [dev] Flash produced a more physically coherent glass cube, whereas Gemini 3 Pro's cube suffers from a 'missing' top face, making the book look like it is balancing on thin edges. However, Gemini 3 Pro handled the text and the 'behind the glass' positioning of the plant much better.
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] Flash
- + Excellent motion blur on the background vehicles, creating a sense of a busy street.
- + Highly realistic skin texture and facial features on the subject.
- + Complex mechanical details on the bicycle and the ground tools.
- − The bicycle's anatomy is slightly warped, with the frame appearing to intersect with the man's legs incorrectly.
- − The lighting on the man's hands is a bit inconsistent with the rainy environment.
Nano Banana Pro
- + The 'imperfect framing' prompt is perfectly executed with the pole on the right and the subject being off-center.
- + Incredible atmospheric realism with the wet pavement reflections and rainy city background.
- + The bicycle mechanics, kickstand, and the man's posture are very believable.
- − The motion blur on the passing taxi is less pronounced than requested.
- − The background figures/umbrellas are a bit generic.
Verdict: While FLUX.2 [dev] Flash produces a very high-detail portrait with great motion blur, Gemini 3 Pro Image Preview captures the 'candid' and 'imperfect framing' essence of the prompt far better. Gemini delivers a more authentic street photography aesthetic with superior environmental storytelling and convincing pavement reflections.
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] Flash
- + Excellent engraving details on the pauldrons
- + Clearer and more distinct beads and braids
- + High fidelity cloth texture and leather grain
- − The bokeh sparks appear a bit more like static dots than glowing embers
- − Face looks slightly 'cleaner' than the 'battle-worn' description suggests
Nano Banana Pro
- + Stronger atmospheric lighting with more realistic warm torchlight reflections
- + Superior skin texture with realistic dirt and grit that fits the 'battle-worn' prompt
- + Very lifelike eyes and expression
- − The leather strap has some minor clipping/merging issues with the plate
- − Engravings on the armor are slightly less crisp than in Model A
Verdict: Both models followed the prompt exceptionally well, capturing the intricate armor, braided hair, and lighting. FLUX.2 [dev] Flash has sharper technical details in the engravings and leatherwork, but Gemini 3 Pro Image Preview provides a more convincing 'battle-worn' atmosphere with better skin texture and more natural integration of the torchlight and sparks.
Chalkboard Menu
Text-to-Image“Handwritten-style chalkboard menu in a cozy café, all text rendered in the exact same realistic chalk handwriting style with natural variations in letter size, slight slant, and chalk texture — no printed or digital fonts anywhere on the board. Title at the top in elegant cursive chalk handwriting: ‘TODAY’S SPECIALS – APRIL 30, 2026’. Below it, three menu items also in the same handwritten chalk style: ‘Truffle Mushroom Risotto – $24’, ‘Grilled Octopus with Lemon & Herbs – $28’, ‘Brown Butter Chocolate Chip Cookies – $9’. At the very bottom, smaller text in the identical handwritten chalk style (slightly smaller but still clearly legible with the same handwriting characteristics): ‘All items made fresh daily • Ask about our gluten-free options’. Warm ambient café lighting, visible chalk dust and smudges, realistic handwriting imperfections, no clean printed text anywhere.”
AI Judge Analysis
FLUX.2 [dev] Flash
- + Excellent chalk texture on the lettering with visible powdering and strokes.
- + Very high level of realism in the board's smudge marks and background cafe environment.
- + Perfectly followed the prompt's specific date and price points.
- − The layout of the 'Grilled Octopus' line is slightly awkward with the trailing dash.
- − Small spelling/spacing artifact in the bottom line with 'gluten-free'.
Nano Banana Pro
- + Very clean and legible handwriting layout.
- + Great atmospheric lighting within the café setting.
- + Excellent adherence to the full menu list and pricing.
- − The handwriting looks slightly more uniform/digital than the requested 'natural variation' chalk style.
- − The chalk texture on the letters is less pronounced compared to the board smears.
Verdict: FLUX.2 [dev] Flash captures the specific 'chalk' texture much more effectively, making the handwriting look truly hand-drawn with pressure variations. Nano Banana Pro produces a very beautiful image, but the text styling feels slightly too perfect and consistent for a genuine hand-lettered chalkboard. FLUX.2 [dev] Flash is the winner for its superior rendering of the requested chalk medium.
The Capybara Taxi Driver
Text-to-Image“Photorealistic scene inside a yellow New York taxi at night. A capybara is driving, wearing a yellow taxi driver cap and a dark jacket. It has a calm, professional expression and both front paws on the steering wheel. In the back seat sits a human businesswoman in a coat, looking at her phone with a completely normal, bored expression (as if this is just another normal ride). Through the windows you can see the streets of Manhattan at night with blurred lights. Realistic taxi interior, photorealistic, detailed fur and fabric, 35mm lens, night lighting with reflections, shallow depth of field.”
AI Judge Analysis
FLUX.2 [dev] Flash
- + Excellent character placement and facial expressions on both the capybara and the human.
- + Very clean, cinematic lighting and high resolution.
- + Effective use of the 'T' logo on the cap to represent a taxi service.
- − The passenger is sitting in the front passenger seat instead of the back seat.
- − The paws on the steering wheel look slightly anthropomorphized/distorted.
Nano Banana Pro
- + Correctly places the human passenger in the back seat as requested.
- + Realistic dashboard details including the taxi meter and rain on the windshield.
- + Natural-looking paws on the steering wheel.
- − The passenger's face is slightly less clear and detailed than Model A.
- − The 'TAXA' type sign on the roof is partially cut off and less clear.
Verdict: Nano Banana Pro followed the spatial instructions much better by placing the businessman in the back seat, creating a more realistic taxi composition. While FLUX.2 [dev] Flash has slightly cleaner lighting and sharper character expressions, it failed the core instruction of positioning the passenger in the back.
The Halloween Invitation
Text-to-Image“Vintage gothic Halloween party invitation. Dark parchment poster, spooky border with webs and thorns, central glowing jack-o-lantern, bats, twisted trees, moody night sky. Add elegant gothic title text saying "Halloween Party Invitation", a small scroll banner saying "You are invited to a night of frights", and event details at the bottom: Date: 30.10.2026 Time: 7pm Location: The Arches, NYC Spooky but polished, cinematic lighting, square format.”
AI Judge Analysis
FLUX.2 [dev] Flash
- + Excellent typography rendering with almost perfect spelling
- + Followed the request for a scroll banner effectively
- + Detailed spider web integration in the corners
- − Includes a line of gibberish text 'Hurk: 03698' that wasn't requested
- − The background trees are less defined compared to the competition
Nano Banana Pro
- + Atmospheric cinematic lighting with high contrast
- + Very clean and accurate text layout with no hallucinated phrases
- + Dynamic composition with curving trees framing the central subject
- − The 'webs' in the border are slightly less prominent
- − The scroll banner is a bit squashed and small
Verdict: Both models followed the prompt exceptionally well, producing high-quality gothic invitations. FLUX.2 [dev] Flash has slightly more intricate border details but suffers from a line of nonsensical text, whereas Nano Banana Pro delivers a cleaner, more professional composition with superior lighting and no text errors.
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] Flash
- + Perfectly rendered text with consistent font weight
- + Excellent 'miniature' feel with high-clarity PBR textures
- + Precise 45° isometric angle and centered composition
- − The sushi roll geometry is slightly unusual with fish draped over a maki roll
Nano Banana Pro
- + High level of charming detail including tea with steam and chopsticks
- + Excellent 'cartoon' aesthetic with soft, rounded edges
- + Well-placed flag icon and bold typography
- − Text arrangement is slightly off-center compared to the diorama
- − Diorama base is less centered in the square frame
Verdict: Both models followed the prompt exceptionally well, capturing the isometric 3D miniature style. FLUX.2 [dev] Flash is preferred for its technical precision, featuring perfectly centered text and a cleaner professional look, whereas Gemini 3 Pro adds more creative flair with tea and chopsticks but is slightly less balanced in its framing.
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] Flash
- + Excellent composition with a natural grouping of the animals.
- + Superior rendering of lighting and dew sparkles with realistic god rays.
- + Very high detail in the fur texture and butterfly wings.
- − Included five animals instead of the requested four (two bunnies/rabbits).
- − The kitten's pose and connection to the puppy's leg are slightly awkward.
Nano Banana Pro
- + Perfectly followed the count of four specific animals requested.
- + Captures the 'playfully chasing' and 'tumbling' action better than Model A.
- + Vibrant colors and high expressive facial features on all animals.
- − The puppy's front right paw is anatomically messy and blurred.
- − Lighting feels slightly more synthetic and 'glowy' compared to Model A.
- − Only one butterfly is present, whereas the prompt suggested plural 'butterflies'.
Verdict: Both models captured the wholesome vibe and high detail requested, but they failed in different ways regarding prompt adherence. FLUX.2 [dev] Flash produced a more photorealistic image with beautiful lighting, but it failed the count by including an extra rabbit. Gemini 3 Pro Image Preview followed the animal list perfectly and captured more dynamic movement, but suffered from anatomical blurring in the puppy's paws and a more digital, less photorealistic art style.
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] Flash
- + Follows the specific icon requests for Saturn V and the lunar module variants.
- + Accurately names the crew members and labels major steps correctly.
- + Uses a realistic yet clean NASA-inspired color palette.
- − The layout is cluttered and lacks a clear logical flow between steps.
- − Contains significant text artifacts and several duplicated labels like 'Landing' and 'Descent'.
- − Technical errors in icons, such as two Saturn V rockets and a misspelled 'Sataurr' Iccòn'.
Nano Banana Pro
- + Superior infographic composition with a clear, readable path connecting all six steps.
- + Perfect adherence to the 'flat-vector style' with crisp lines and consistent iconography.
- + Excellent text rendering with no spelling errors and professional typography.
- − Step 3 (Translunar) lacks a distinct icon compared to the path itself.
- − The trajectory path logically loops strangely between Earth and the Moon.
Verdict: Gemini 1.5 Pro produced a professional-grade infographic with a clear visual hierarchy and excellent typography that perfectly matches the 'modern vector' request. While FLUX.1 [dev] Flash attempted more complex icons, it failed significantly on layout, spelling, and organization, resulting in a cluttered and repetitive image.
