What kinds of prompts work best for nano banana AI doll generation? +

The most effective prompts for nano banana AI doll generation are detailed and specific. Include information about the character's appearance (hair color, eye color, facial features), clothing/outfit details, pose, expression, background/setting, and any special effects or lighting. Also specify the artistic style (anime, realistic, chibi, etc.). The more specific your prompt, the better the AI can match your vision. Remember to start with "nano banana:" to activate the model.

What's the difference between Gemini 2.5 flash image and nano banana? +

Gemini 2.5 flash image is Google's large language model that can handle text, code, and image generation tasks. nano banana is a specialized AI image generation capability within Gemini that's particularly optimized for creating stylized character dolls and illustrations. When you use the "nano banana:" prefix in your Gemini 2.5 prompts, you're telling the system to use the specialized nano banana model for image generation instead of the standard Gemini image generator. nano banana produces more consistent character designs with better attention to small details compared to standard Gemini image generation.

Is nano banana AI doll generation free to use? +

Basic access to nano banana AI doll generation through Gemini 2.5 is available for free with limitations on the number of generations per day. To access more generations and advanced features, you'll need a Gemini Advanced subscription (part of Google One AI Premium plan), which costs $19.99/month. The subscription removes daily limits and provides access to more detailed generations and higher resolution outputs. For commercial use cases or high-volume needs, enterprise pricing options are available.

How can I ensure consistent character design across multiple AI doll generations? +

To maintain consistency across multiple AI doll generations, create a detailed character "seed" prompt that includes all the defining characteristics you want to preserve. Save this prompt and use it as the foundation for all variations, only changing the specific elements you want to modify (pose, outfit, background, etc.). Using descriptive character identifiers like "the blue-haired anime girl with star-shaped pupils" helps the AI recognize it's generating the same character. If you're creating multiple characters in the same style, include consistent style descriptors in each prompt. nano banana is significantly better at maintaining character consistency than standard AI image generators.

Can I edit or modify AI dolls after they're generated by nano banana? +

Yes, there are several ways to edit or modify AI dolls after generation:

1. Iterative prompting: Use the initial result as a reference and create a new, more specific prompt to refine details.

2. Inpainting/outpainting: Some versions of Gemini support inpainting, which allows you to modify specific parts of an image while keeping the rest intact.

3. External editors: Download your AI dolls and use image editing software like Photoshop, GIMP, or even specialized AI editing tools like Adobe Firefly for further refinements.

4. Prompt with changes: Generate a new version with a prompt like "nano banana: The same anime girl character as before, but now with a winter outfit instead of summer clothes."

Can I use nano banana AI (Gemini 2.5 Flash Image) dolls commercially? +

1. Personal use: AI dolls created with the free tier can be used for personal, non-commercial projects.

3. Enterprise users: Have the most extensive commercial rights.
