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.”
Nano Banana
Stable Diffusion 3.5 Medium
AI Judge Analysis
Nano Banana
- + Excellent photorealism with realistic soft window lighting and depth of field.
- + Accurate rendering of the glass cube's refraction and the wooden table's texture.
- + Perfect adherence to the plant and light source directions.
- − Floating sphere lacks a logical physical support inside the cube.
Stable Diffusion 3.5 Medium
- + Successfully follows all prompt elements including the specific sphere color.
- + The lighting is bright and clear.
- − The glass cube has distorted edges and inconsistent geometry.
- − The red book looks overly simplified and lacks realistic texture compared to Model A.
- − Overexposed areas in the background reduce overall visual quality.
Verdict: Nano Banana produces a significantly higher quality image with realistic textures, sophisticated lighting, and better depth of field. While both models struggled with the physics of the floating sphere, Nano Banana's adherence to the 'soft window light' and the 'plant behind the cube' was much more aesthetically pleasing and technically sound than Stable Diffusion 3.5 Medium.
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.”
Nano Banana
Stable Diffusion 3.5 Medium
AI Judge Analysis
Nano Banana
- + Excellent photographic quality with realistic textures and lighting.
- + Correctly implements the shallow depth of field and rainy atmosphere.
- + Superior anatomical and mechanical detail in the man and the bicycle.
- − The cars in the background are static rather than having the requested motion blur.
Stable Diffusion 3.5 Medium
- + Stronger adherence to the 'candid' and 'imperfect framing' part of the prompt.
- + Atmospheric wet pavement reflections.
- − The man's hands are severely distorted and lack realistic structure.
- − The bicycle frame logic is broken near the handlebars.
- − Image has a slightly noisy, lower-resolution feel compared to Model A.
Verdict: Nano Banana is the clear winner due to its significantly higher visual fidelity and realistic rendering of the subject. While Stable Diffusion 3.5 Medium captured the 'candid' and 'unbalanced' feel of the prompt slightly better, it failed on technical aspects like hand anatomy and bicycle structure, which Nano Banana handled with professional-grade clarity.
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.”
Nano Banana
Stable Diffusion 3.5 Medium
AI Judge Analysis
Nano Banana
- + Excellent anatomical realism and skin texture

- − Failed the 'exploded burger' instruction; the burger is mostly assembled.
- − Text rendering is cramped and lacks the requested fiery/glowing effect.
- − The price starburst is stylized like a simple icon rather than an integrated ad element.
Verdict: Nano Banana followed every instruction in the prompt, successfully creating a dynamic, exploded burger view with high-quality text and a fiery starburst. Stable Diffusion 3.5 Medium failed the core layout requirement by showing a nearly assembled burger and struggled with the specific text effects and starburst design.
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.”
Nano Banana
Stable Diffusion 3.5 Medium
AI Judge Analysis
Nano Banana
- + Excellent text rendering with near-perfect spelling of complex menu items.
- + Highly realistic chalk texture and natural handwriting variations.
- + Authentic café atmosphere with shallow depth of field and believable lighting.

Stable Diffusion 3.5 Medium
- + Artistic chalk-smudge effects on the background which look authentic.
- + Follows the layout requested in a direct, front-facing composition.
- − Severe spelling errors and illegible text throughout the board.
- − Fails to render the specific menu items and date accurately.
- − The handwriting style is inconsistent and messy rather than elegant.
Verdict: Nano Banana is the clear winner as it successfully rendered the specific text items requested in the prompt with high legibility and realistic chalk textures. Stable Diffusion 3.5 Medium struggled significantly with text adherence, producing garbled words like 'Oocclutes' and 'belButer' instead of the requested menu items.
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.”

Verdict: Nano Banana produces a significantly more realistic and detailed image, though it places the passenger in the front seat instead of the back. Stable Diffusion 3.5 Medium follows the spatial layout instructions better but fails to include the phone and has noticeable issues with the capybara's paws.
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.”
Nano Banana
Stable Diffusion 3.5 Medium
AI Judge Analysis
Nano Banana
- + Excellent text rendering with no spelling errors
- + Polished and cohesive cinematic lighting

Nano Banana
Stable Diffusion 3.5 Medium
AI Judge Analysis
Nano Banana
- + Successfully included all four requested animals (dog, cat, bunny, fox).
- + Excellent rendering of 'god rays' and dew sparkles as requested in the prompt.
- + Superior composition showing playful interaction and tumbling behavior.
- − The fur texture is slightly soft/digital looking rather than truly hyper-photorealistic.
Stable Diffusion 3.5 Medium
- + Vibrant, saturated colors that create a joyful mood.
- + The fur texture on the fox and puppy shows good individual strand detail.
- − Failed to include the baby bunny, a key part of the prompt.
