Google AI Studio releases comprehensive developer guide for Nano Banana Pro, featuring thinking capabilities, search grounding, 4K output, and advanced image mixing
Google AI Studio has released a complete developer tutorial for Nano Banana Pro (Gemini 3 Pro Image), introducing developers to the advanced features of this next-generation AI image generation model. While the Flash model (Nano Banana) brought speed and affordability, the Pro version introduces groundbreaking capabilities including "thinking" processes, search grounding, and stunning 4K output.
Nano Banana Pro isn't just drawing—it's thinking. The model can reason through complex, twisted prompts before generating an image, and developers can peek into its thought process by enabling in the thinking configuration. This transparency helps developers understand how the model interprets requests, creating a more collaborative experience.

For example, developers can ask it to visualize the current weather forecast, and the model will fetch real-time data and create corresponding visualizations.
For print-quality images, Nano Banana Pro supports 4K resolution. While 1K or 2K images cost $0.134, 4K images cost $0.24 (plus token costs), providing developers with professional-grade output options.
The model can generate and translate text within images across over a dozen languages, functioning as a universal translator for visual content. Developers can create infographics in one language and then translate them to another while maintaining the same visual design.
While the Flash model can mix up to 3 images, the Pro model can handle up to 14 images simultaneously. This capability is perfect for creating complex collages or showcasing entire product lines in a single generation.
Developers can access Nano Banana Pro through Google AI Studio by signing in with their Google account and selecting "Nano Banana Pro (Gemini 3 Pro Image)" from the model picker. Unlike the Flash version, the Pro version requires billing to be enabled on the Google Cloud project.

The tutorial showcases several Pro-exclusive capabilities:
The guide emphasizes several key prompting strategies:
Image generation with Nano Banana Pro is more expensive than the Flash version, especially for 4K images. Developers can save 50% on generation costs by using the Batch API, though this may require waiting up to 24 hours for results.
