Nano-Banana Crash Course: The Offbeat Way to Play with AI (with Prompts)

The new update of the nano-banana model has once again started a “Ghibli wave” with the help of GPT-4o and Gemini 2.5. Many creators are now showing amazing AI image tricks—from multi-image collages, simple edits, figure making, turning flat plans into 3D buildings, making comic stories, to poster design—that are changing the way AI images are made. This guide puts together the most popular methods, step by step, with prompt examples, so you can learn fast and unlock the newest AI skills with ease.

Quick Guide for Nano-Banana Prompts

• Multi-Element Collage: Smarter AI Compositions
• Local Editing: Precision AI Retouching
• Everything Becomes a Figure: AI Toy/Figurine Generation
• From Blueprints to 3D Cities
• Comic Generation: AI Telling Stories

Multi-Element Collage: Smarter AI Compositions

Highlight of the update: AI can now automatically handle backgrounds, object positioning, and lighting consistency when stitching multiple images together.

Steps:

1. Make a collage image by placing the objects (shoes, headphones, cameras, watches, bags, etc.) on one canvas.
2. Add labels to each item (e.g., “white sneaker,” “headphone”).
3. Upload the collage as a reference, then call back the labels in your prompt and describe the scene.

Prompt Example:

A man is standing in a modern electronic store analyzing a digital camera. He is wearing a watch. On the table are sunglasses, headphones, a shoe, a helmet, a white sneaker and a black sneaker.

This method improves accuracy and bypasses the usual AI limitation on object counts.

Local Editing: Precision AI Retouching

Inpainting is another highlight. Unlike older versions, nano-banana can now modify a specific area without altering the rest of the image.

Partial Editing Steps

1. Upload the image.
2. Describe the area to be modified and the desired effect.

Use Cases:

• Change facial expressions
• Adjust body poses
• Generate furniture mockups
• Erase a character completely

Editing is now intuitive and doesn’t require overly complex commands.

Everything Becomes a Figure: AI Toy/Figurine Generation

Since Imarena first leaked it, AI figure generation exploded in popularity.

Steps:

1. Prepare a reference image (person/pet/object).
2. Define pose, base, and props.
3. In your prompt, specify materials and scale:
   • Character: “1/7 scale PVC figure,” “cel-shade outline”
   • Head: “nendoroid/chibi 1:2”
   • Accessories: “acrylic stand,” “metallic finish”
   • Base: “transparent circular base”

Upload the reference, and AI will “turn it into a figure.” Pets, real people, and anime characters are now collectible-style models, flooding social media.

Prompt Example:

Use the nano-banana model to create a 1/7 scale commercialized figure
of the character in the illustration, realistic style, transparent acrylic base.

From Blueprints to 3D Cities

Another surprise feature: 2D floor plans → 3D city models.

steps:

1. Prepare a city plan (building outlines, roads, green areas, contour lines).
2. Label building attributes (height, floors, facade material).
3. Upload the drawing and set camera angle (e.g., axonometric 30°).

AI then converts the flat plan into a coherent, proportional 3D cityscape.。

Comic Generation: AI Telling Stories

Nano-banana can also generate panel-based comics.

Steps:

1. Upload a protagonist photo → generate the first panel (with dialogue).
2. Use that as reference for the next, continuing the story.
3. Replace names and dialogue as needed for consistency.

This “panel → continuation → live edits” flow lets you finish a 4-panel or 9-panel story in no time.
