Side-by-side comparison

Use Nano Banana 2 when speed matters

A social media manager does not always need a museum-grade image. Sometimes they need five variations before lunch.

Nano Banana 2 is a strong fit for prompts like:

Create three variations of this product photo for a summer sale. Keep the product unchanged, change the background, add warm outdoor lighting, and leave clean space for a headline.

Or:

Turn this room photo into three interior design concepts: Scandinavian, warm minimal, and boutique hotel. Keep the room layout the same.

The workflow is conversational: create, adjust, repeat.

Use ChatGPT Images 2.0 when structure matters

If you need an infographic, brochure, educational poster, ad concept, or multi-panel visual story, structure becomes more important than speed.

Try:

Create a clean infographic explaining how AI agents save time in software development. Include four stages: plan, inspect, edit, test. Use a professional editorial style, readable headings, simple icons, and a clear visual hierarchy.

Or:

Create a three-image campaign for a Microsoft 365 productivity guide. Keep the same visual style, realistic workspace photography, and consistent color palette across all images.

ChatGPT Images 2.0 is especially useful when you need the image to communicate information, not just look attractive.

Define the format

Mention whether you need:

• square social post;
• blog hero image;
• LinkedIn banner;

Add negative constraints

Tell the model what to avoid:

• no fake logos;
• no unreadable text;

Iterate in small steps

Do not rewrite the whole prompt every time. Say:

Keep everything else the same, but make the lighting softer and remove the text from the background.
