What is Nano Banana Pro?

Nano Banana Pro is the viral community nickname for Gemini 3 Pro Image, Google DeepMind's state-of-the-art image generation and editing model released in November 2025.

Unlike its predecessor (Nano Banana / Gemini 2.5 Flash), the Pro version features:

• "Thinking" Process: It reasons through your prompt before generating, fixing logic errors (e.g.,Then infographic showing how to create an elichi chai.).

  

  
  

• Perfect Text Rendering: It can spell long sentences and complex logos accurately.

• Search Grounding: It connects to Google Search to generate factually accurate diagrams. 

• Few-Shot Design: It accepts up to 14 reference images to maintain strict brand or character consistency.
  
  

  

The "Perfect Prompt" Formula

To get SOTA (State-of-the-Art) results from Nano Banana Pro, stop using 2023-era prompts. The model understands natural language and distinct structural components.

The Formula:

[Subject + Adjectives] doing [Action] in [Location/Context]. [Composition/Camera Angle]. [Lighting/Atmosphere]. [Style/Media]. [Specific Constraint/Text].

Example breakdown:

• Subject: A translucent glass robot barista...

• Action: ...pouring latte art...

• Location: ...inside a cozy, cyberpunk coffee shop...

• Composition: ...Macro close-up shot, shallow depth of field (f/1.8)...

• Lighting: ...illuminated by neon pink and teal signage reflection...

• Style: ...Cinematic 8k render, Octane render style.

• Text Constraint: The robot's chest display reads "WAKE UP" in bold LCD font.

5 High-Performance Prompt Templates

Copy and paste these templates into the Atlabs AI Image Generation Tool to test the model's capabilities.

1. The "Text-Perfect" Marketing Asset

Best for: Logos, Posters, Social Media Ads.

Prompt: "Create a minimalist movie poster for a thriller titled 'THE SILENT ECHO'. The text should be large, distressed sans-serif font at the top. The visual is a lone cabin in a snowy forest viewed from above. High contrast black and white. Ensure the title is perfectly legible and centered."

2. The "Fact-Grounded" Infographic

Best for: Educational content, Manuals, Presentations.

Prompt: "Generate a step-by-step infographic showing how to make Elaichi Chai. Use the model's world knowledge to include accurate ingredients like cardamom pods, loose tea leaves, and milk. Style: Clean vector art with pastel colors. Label the ingredients correctly."

3. The "Brand Consistency" Workflow (Multi-Shot)

Best for: Designers using Reference Images.
(Upload 3-5 images of your product/character first)

Prompt: "Using the attached reference images of 'Sneaker X', generate a lifestyle photography shot of the sneaker sitting on a wet city street at night. Maintain the exact logo placement and colorway of the reference. Cinematic lighting, 4K resolution."

4. The "Thinking" Logic Test

Best for: Complex scenes, Surrealism.
(Ensure "Thinking" mode is enabled in the model dropdown)

Prompt: "A crystalline chess set where the pieces are made of freezing water and the board is made of burning lava. The pieces are melting slightly where they touch the board. Macro photography, hyper-realistic. Reason through the lighting interactions between fire and ice before generating."

5. The "Localized" Campaign

Best for: Global Marketing.

Prompt: "A bustling street market scene in Tokyo. Neon signs are visible. Generate a billboard in the background that says 'Fresh Start' written in Japanese Kanji. Cyberpunk aesthetic, volumetric fog."

How do I use reference images in Nano Banana Pro?

Nano Banana Pro supports a 14-image context window. In the Atlabs AI edit image or generate image tool interface:

1. Click the "plus" (+) icon to upload images (style guides, logos, character sheets).

2. Instruct the model: "Use the uploaded images as a strict style reference..." or "Keep the character from Image 1 but put them in the pose from Image 2."

Can Nano Banana Pro edit existing images?

Yes. The model supports Conversational Editing.

1. Upload or generate an image.

2. Type a natural language change: "Change the sunny day to a rainy night" or "Remove the person in the background and replace them with a potted plant."
   
   

   

   
   

3. The model uses its "Thinking" capability to adjust lighting and reflections to match the new edit automatically.

Common Mistakes to Avoid

1. Over-prompting: You don't need "4k, trending on artstation, masterpiece" spam anymore. Nano Banana Pro understands natural language. Be descriptive, not repetitive.

2. Vague Text Instructions: Don't just say "add text." Say: "Write the text 'HELLO WORLD' in a bold, red, serif font on the sign."
