Nano Banana Pro API
Comprehensive guide to understanding, implementing, and maximizing the potential of the Nano Banana Pro API for your projects
What is the Nano Banana Pro API?
The Nano Banana Pro API is a powerful solution for developers. **Nano Banana Pro** (also referred to as **Nano Banana 2** or officially as **Gemini 3 Pro Image**) is Google's latest state-of-the-art image generation model. The Nano Banana Pro API is described as an "AGI-level" imaging tool because it goes beyond simple pattern matching to actually "reason" about the scene. The Nano Banana Pro API powers the image generation capabilities within the Gemini 3 ecosystem and integrates real-time data from Google Search into generated images through its Search Grounding feature. **Reasoning vs. Pattern Matching:** The biggest improvement in Nano Banana Pro API over the original is that it "plans" the scene. While the original Nano Banana simply matched shapes and colors from training data, the Nano Banana Pro API understands *causality* and *relationships* (e.g., knowing that a "reflection" must change if the object changes). **Consistency:** The Nano Banana Pro API can merge up to 8 reference photos and keep identities consistent across different angles, lighting conditions, and settings - perfect for storytelling and character design. **Real-Time Integration:** Unlike the original closed system, the Nano Banana Pro API connects to Google Search to fetch live context, making it a "world model" rather than just an art generator.

Important Considerations
Understanding the limitations helps you make informed decisions
Content Safety Filters: Strict filters block copyrighted characters and public figures
Minor Hallucinations: May make small errors in specific details like clock times or map labels
Text Scaling in 4K: Text rendering quality may not always improve at higher resolutions
Higher Cost: Approximately 7-8x more expensive than original Nano Banana due to reasoning compute
Maximum 8 reference images for image-to-image mode
Maximum file size of 30MB per image (jpeg/png/webp formats)
