The Gemini AI Nano Banana trend has quickly become one of the most exciting viral phenomena of 2025. It is a specific prompting style using Google’s Gemini image-to-image capabilities to transform standard selfies into hyper-realistic 3D figurines, nostalgic retro portraits, and cinematic art—all while preserving facial identity.
If you are looking to turn your photos into collectible toys or saree portraits, you don’t need 3D modeling skills. You just need the right words.
At How To Prompt AI, we have analyzed the mechanics behind this trend. This guide provides the exact, copy-paste prompts you need, the technical logic behind why they work, and how to refine them for professional results.

What is the Nano Banana Trend?
The “Nano Banana” trend isn’t a new app—it is a community-coined term for a specific high-fidelity aesthetic achievable with Google Gemini AI’s image-to-image editing system.
It is characterized by two distinct features:
-
Hyper-Texture: The ability to render surfaces like “glossy resin,” “silk,” or “vintage film grain” with tactile realism.
-
Identity Lock: Unlike older AI models that replaced faces entirely, this trend utilizes Gemini’s ability to analyze facial features and maintain the subject’s likeness even when transforming them into a 3D toy or a video game character.
Note: The “Nano” in the name implies the efficiency of the prompts, often optimized for Gemini Nano (Google’s most efficient model built for on-device tasks), allowing for fast iterations on mobile devices.
The Technology: How Identity Preservation Works
Before diving into the prompts, it is crucial to understand the three-stage process Gemini uses to execute these edits.
1. Identity Preservation (The Anchor)
Gemini analyzes the facial features and objects in the original photo. When you prompt “same person,” it locks these biometric landmarks as immutable constraints, ensuring the subject remains recognizable.
2. Contextual Editing (The Shift)
This is where the AI swaps the “environment” pixels. It alters clothing, backgrounds, and styles based on your text prompt while ensuring the new elements look natural.
3. Stylistic Rendering (The Filter)
Finally, the AI applies artistic effects. For the “Banana” figurine look, it applies a specific texture map—like 3D figurine textures, retro filters, or cinematic shadows.
10 Copy-Paste Gemini Nano Prompts
We have categorized these prompts by style. To use them, upload your photo to Gemini and paste the text below.
Category 1: The Viral 3D Figurines
The flagship of the Nano Banana trend. This turns you into a desk collectible.
1. The Classic Resin Miniature
Prompt: “Create a 3D miniature figurine of this person, styled like a collectible toy. Pose: standing with crossed arms and a confident smile. Texture: glossy resin plastic, realistic clothing details, placed on a round black display stand with a studio light background.”
- Why it works: The keyword “glossy resin plastic” triggers the specific light reflection that makes the image look like a physical object.
2. The 3D Pet Birthday Celebration
Prompt: “Generate a 3D miniature figurine of this dog. The figurine should be placed on a wooden desk with birthday decorations around it. Style: hyper-realistic plastic resin texture, glossy finish, bright studio lighting, collectible figurine style.”
- Pro Tip: Ensure the original pet photo is well-lit for the best texture mapping.
Category 2: Cultural & Retro Portraits
These prompts focus on fabric texture and atmospheric lighting.
3. The 1980s Retro Couple
Prompt: “Create a 1980s retro-style couple portrait. The couple should be smiling, sitting on a vintage brown leather sofa, with warm golden lighting. Outfits: man in a blue denim shirt and black pants, woman in a white saree and necessary adornments. Add soft grainy film texture and a faded photo album look, as if taken in a retro photo studio.”
4. The Royal Saree Portrait
Prompt: “Transform this person into a traditional saree portrait. Outfit: silk saree in deep maroon with golden zari embroidery, paired with temple jewelry. Background: ornate palace interior with golden lamps. Lighting: cinematic soft glow, realistic fabric textures, traditional portrait style.”
Category 3: Fantasy & Pop Culture
5. The 16-Bit Gamer
Prompt: “Turn this person into a 16-bit video game character inside a classic 2D platformer level. Outfit: colorful pixelated armor with glowing accents. Background: floating pixel platforms with retro clouds and mountains. Style: pixel art, bright arcade colors, cartoonish proportions, crisp sharp outlines.”
6. The Marvel-Style Comic Strip
Prompt: “Create a 9-frame comic book sequence featuring this couple as superheroes. Frame 1: they discover their powers. Frame 2-4: training montage. Frame 5: battle with villain in a futuristic city. Frame 6: dramatic mid-air fight. Frame 7: saving civilians. Frame 8: victory pose. Frame 9: close-up of their hands holding. Style: Marvel comic book, bold colors, inked outlines.”
7. The Elf Warrior (Object Transformation)
Prompt: “Reimagine these scissors as a fantasy elf warrior. The scissors blades become shimmering silver swords, and the handle turns into ornate armor. Add glowing blue runes, magical forest background, cinematic fantasy artwork style, epic RPG vibe.”
Category 4: Conceptual Art
8. Tea With Your Younger Self
Prompt: “Create an image of the same person as an adult sitting at a tea party with their 7-year-old younger self. Scene: cozy living room with pastel wallpaper, a small wooden table, porcelain teacups, and stuffed toys in the background. Style: heartwarming, realistic yet slightly dreamy.”
9. The Pencil Sketch
Prompt: “Convert this portrait into a hand-drawn pencil sketch. Style: hyper-detailed graphite pencil strokes, soft shading, textured paper background, cross-hatching details around eyes and hair. Lighting: soft grayscale shading for depth.”
10. The Tropical Architecture Makeover
Prompt: “Transform this modern house into a tropical island villa. Roof made of bamboo and palm leaves, walls in bright pastel shades. Surroundings: palm trees, coconuts, colorful tropical flowers, hammock swinging outside. Style: hyper-detailed, postcard-like tropical paradise aesthetic.”
Advanced Prompt Engineering: The Syntax
To create your own “Nano Banana” prompts, do not just guess. A generic prompt like “make this retro” will yield generic results. You must be specific.
The Formula:
[Action] + [Subject Definition] + [Style/Texture Modifier] + [Lighting/Environment] + [Identity Constraint]
| Component | Example | Why it matters |
|---|---|---|
| Action | ”Transform this photo…” | Tells the AI this is an edit, not a new generation. |
| Subject | ”…into a 3D figurine…” | Defines the target morphology. |
| Texture | ”…glossy resin, plastic…” | Crucial: Defines the “Nano Banana” look. |
| Lighting | ”…studio spotlight…” | Ensures 3D objects look 3D via shadows. |
| Constraint | ”…keeping facial identity…” | Prevents the AI from generating a random person. |
Common Mistakes to Avoid:
-
Vague Instructions: Avoid short prompts; they lead to bland edits.
-
Style Overload: Do not mix conflicting styles (e.g., “pixel art” and “hyper-realistic”) as it confuses the AI.
Troubleshooting Common Errors
Even with perfect prompts, AI can struggle. Here is how to fix common issues:
Problem 1: The face doesn’t look like me.
- Fix: Strengthen the identity constraint. Add “Identity preserved” or “same person” to ensure Gemini maintains facial features.
Problem 2: The 3D figurine looks like a drawing, not a toy.
- Fix: You are missing lighting cues. Add “ray-traced shadows,” “studio lighting,” or “glossy finish.” The AI needs to know how light hits the surface to create depth.
Problem 3: The Saree or Outfit is wrong.
- Fix: Be hyper-specific. Instead of just “saree,” describe the material (silk), color (maroon), and details (zari embroidery).
Conclusion
The Gemini Nano Banana trend proves that AI is shifting from simple filters to complex, style-driven rendering. Whether you are creating a sentimental “Tea with Younger Self” portrait or a playful “3D Pet Figurine,” the key lies in the specificity of your prompt.
