Google Banana Pro In-Depth Review:

AI Image Generation Enters a Horrifying Evolution!

It’s like a celebration lately—several major model releases in one week. First came Musk’s Gork 4.1, then Google’s Gemini 3.0 Pro yesterday, which received a flood of rave reviews.

Sam Altman couldn’t stay on the sidelines either—he gave Gemini 3 a thumbs-up (great sportsmanship, haha). Meanwhile, OpenAI quietly launched GPT-5.1 Pro and GPT-5.1-Codex-Max.

And tonight, Google’s Nano Banana Pro gets a major update! Remember the viral Banana 1 from a while back? Google is going all out—its image models keep upgrading in just months, even weeks. The evolution speed is simply terrifying.

No more rambling—let’s dive into its improvements! The experience link is at the end of the article.

Test Dimensions & Prompts

1. Optical Physics: Prismatic Dispersion

• Physics Principle: White light enters a prism, and different wavelengths refract at different angles, splitting into a rainbow spectrum (red, orange, yellow, green, blue, indigo, violet).
• Test Challenge: AIs often misdraw rainbow directions or add rainbows without light sources.
• Prompt: A physics laboratory shot of a triangular glass prism sitting on a dark surface. A single thin beam of pure white light enters the prism from the left. Inside the glass, the beam bends, and upon exiting the right side, it splits into a perfect, vibrant rainbow spectrum (dispersion). Dust motes are dancing in the light beams. High contrast, black background, accurate optical physics, ray-tracing render.

2. Light Refraction: The "Broken" Pencil Effect

• Physics Principle: Light changes speed when moving from air to water, causing visual displacement (the object appears "broken") and magnification.
• Key Check: Whether the pencil "breaks" and shifts at the water-air interface.

3. Hand Anatomy & Complex Interaction

• Test Focus: Finger joint logic, physical contact between hands and objects, grip posture.
• Subject: An elderly watchmaker’s hands.
• Prompt: A close-up shot of an elderly watchmaker's hands working on the intricate internal mechanism of a vintage mechanical watch. His wrinkled, weathered fingers are holding delicate tweezers and a tiny gear. The metal parts of the watch are gleaming under a warm desk lamp. The focus is strictly on the fingers and the watch movement. High contrast, detailed skin texture, realistic shadows, macro photography, showing the tension in the hands.

4. Mirror Reflection: Infinity Mirror

• Physics Principle: Infinite light reflection between two parallel mirrors creates a deep tunnel effect.
• Test Challenge: AIs struggle with recursive images—often mess up after a few layers or break perspective.
• Prompt: A conceptual art shot of a person standing between two large parallel mirrors. The reflection creates an infinite tunnel of images receding into the distance. Each successive reflection becomes slightly darker and greener (due to glass tint). The perspective is perfectly linear and converging to a vanishing point. Complex optics, mind-bending, photorealistic.

5. Food Texture & Appetizing Appeal

• Test Focus: Greasiness, steam, ingredient layering.
• Subject: A bowl of Tonkotsu ramen.
• Prompt: A top-down view of a steaming hot bowl of Tonkotsu ramen. The broth is rich and creamy white, topped with slices of tender chashu pork with glistening fat, a perfect soft-boiled egg with a runny orange yolk, fresh green onions, and nori sheets. Steam is rising from the bowl. The texture of the noodles is visible. Warm lighting, appetizing color palette, professional food photography, high fidelity.

6. Surrealism & Logical Fusion

• Test Focus: Natural integration of unrelated objects, creative ideas.
• Subject: A whale made of clouds.
• Prompt: A surreal dreamscape showing a giant whale formed entirely out of white fluffy cumulus clouds, swimming through a deep blue sky above a mountain range. Small birds are flying around the cloud whale. The lighting represents golden hour, illuminating the edges of the cloud shapes. Dreamy atmosphere, fantasy art style, detailed matte painting, sense of wonder and scale.

7. Architectural Space & Geometric Perspective

• Test Focus: Straight line accuracy, spatial depth, wide-angle distortion control.
• Subject: A minimalist modern art museum.
• Prompt: Interior wide shot of a minimalist modern art museum gallery. The space features high concrete walls, a polished concrete floor reflecting the artworks, and a complex geometric skylight casting sharp, angular shadows on the floor. A single person in a red coat stands in the distance for scale. Perfect linear perspective, symmetry, architectural photography, cool color tone, soft daylight, 16mm wide-angle lens.

8. Transparent Materials & Physical Lighting

• Test Focus: Glass refraction, liquid caustics, ice texture.
• Subject: A glass of whiskey.
• Prompt: A product photography shot of a crystal rock glass filled with amber whiskey and a single large clear ice sphere. The glass sits on a dark, polished mahogany table. Harsh rim lighting creates dramatic caustic patterns on the wood surface. Condensation droplets cling to the side of the glass. The ice creates complex refractions. Dark moody atmosphere, ray-tracing rendering style, sharp focus, 8k.

9. Hyper-Realistic Portrait & Skin Details

• Test Focus: Skin texture, pores, facial vellus hair, catchlights in eyes.
• Subject: A 20-year-old Scandinavian woman.
• Prompt: A hyper-realistic extreme close-up portrait of a 20-year-old Scandinavian woman with pale skin and light freckles. The focus is sharp on her eyes, revealing the intricate pattern of her blue irises and the reflection of a window. Her skin texture is imperfect and natural, with visible pores and fine vellus hair. She is looking directly at the camera with a neutral expression. Soft, diffused natural lighting from the left side, shot on a Sony A7R IV with an 85mm f/1.4 lens, depth of field, cinematic texture, raw photo style.

10. Night Rain Urban Portrait

• Test Focus: Wet hair, reflective skin, rain-soaked clothing, neon light reflections.
• Subject: A woman walking in the rain with an umbrella.
• Prompt: A full-body shot of a young woman walking alone down a deserted, neon-lit cyberpunk street on a heavy rainy night. She is holding a clear umbrella, which reflects the vibrant blues, purples, and pinks of the surrounding signs. Her dark hair is slightly wet, clinging to her face. The wet pavement reflects the city lights like a mirror. The atmosphere is melancholic and cinematic. Detailed rain droplets are visible. Shot on an 85mm lens, f/1.8, bokeh city lights, film noir aesthetic, ultra-realistic, 8k.

11. Anime & Cel-Shaded Style

• Test Focus: Flat coloring, smooth lines, anime-style lighting.
• Subject: A cyberpunk girl.
• Prompt: Anime style illustration of a cyberpunk girl with neon blue hair, wearing a futuristic visor and a glowing jacket. She is sitting on a railing overlooking a futuristic Tokyo city at night. The art style is high-quality 2D cel-shaded, similar to Kyoto Animation. Vibrant neon colors of pink, purple, and blue. Detailed background with flying cars and holograms. Emotive eyes, dynamic composition, masterpiece, 4k wallpaper.

12. Chinese Text Accuracy

• Test Focus: Flowchart readability.
• Subject: Hand-brewed coffee process flowchart.
• Prompt: Flowchart for hand-brewed coffee: 1. Bean Selection & Grinding 2. Equipment Preparation 3. Pouring & Extraction 4. Enjoyment

18. Rainy Park Bench

• Test Focus: Wooden texture in rain, puddles, solitary mood.
• Subject: An empty park bench on a rainy night.
