Nano Banana (Gemini 2.5 Flash Image) and Nano Banana Pro (Gemini 3 Pro Image) are Google models for quick and efficient image analysis and creation. These are available through the Gemini API with SDKs (Python, Node.js, etc.), the Files API for large uploads, Firebase, or a CLI. They allow for tasks like visual reasoning, editing with prompts (object removal, pose changes), and complex image analysis within apps. An API key and prompt engineering are needed for optimal results. Key Concepts Nano Banana (Gemini 2.5 Flash Image): It focuses on speed and efficiency for tasks involving a high volume of images. It is effective for consistent character generation and prompt-based editing. Nano Banana Pro (Gemini 3 Pro Image): This offers advanced reasoning, search grounding, and high-fidelity output for complex creative projects. How to Use Get an API Key: Set up authentication with Google AI services. Use the Gemini API: Send requests with multimodal input (text and images). SDKs: Use client libraries (Python, JS, etc.) for easier integration. Files API: Upload larger images or those used repeatedly for better efficiency. Inline Images: Pass Base64 encoded images directly in the request for smaller inputs. Capabilities Image Understanding: Analyze diagrams, sketches, and visual content. Prompt-Based Editing: Remove objects, change poses, or perform local edits with text prompts. Visual Reasoning: Solve hand-drawn equations, understand complex scenes. Document Processing: Analyze entire PDFs, extracting info from text, images, and tables. Consistent Generation: Create consistent characters or products across images. Tools & Interfaces Gemini API/SDKs: This is the main way to integrate into apps. Gemini CLI: This is for terminal-based image analysis (e.g., gemini analyze image.png). Firebase AI Logic: This allows direct integration into apps. Google AI Studio: This is for experimenting with models visually. Example Workflow (Conceptual) python
from google import GenerativeModel
model = GenerativeModel("gemini-2.5-flash-image") # Nano Banana image_data = open("my_banana.jpg", "rb").read() # Read local image
response = model.generate_content(["Describe this image.", image_data]) print(response.text) Key Takeaway: Nano Banana allows developers to build intelligent applications that understand and manipulate visual information, integrating text and images.
