How to Use Nano Banana 2 Prompts Effectively
Nano Banana 2 prompts work best when you combine clear descriptive text with precise technical parameters. The three key settings that control output quality are aspect ratio, image resolution, and response modalities. Aspect ratio determines the frame shape—1:1 for square product photos, 16:9 for wide landscapes, or 4:3 for standard layouts. Image resolution controls detail and processing time; 2K resolution balances clarity with speed, while 4K delivers maximum detail for print-ready assets.
When crafting prompts, be specific about style, lighting, and composition. Instead of "a beautiful room," write "a minimalist living room with warm natural light streaming through large windows, Scandinavian furniture, soft gray walls, and a potted plant in the corner." This level of detail ensures the AI generates exactly what you envision.
Response modalities tell the API what to return. Set "responseModalities": ["TEXT", "IMAGE"] to receive both descriptive text and the generated image. The API returns images as base64-encoded data, which you decode to save as PNG or JPG files. Understanding these fundamentals transforms your prompts from generic requests into precise production instructions.

Example API Request for Generating Nano Banana 2 Images
Integrating Nano Banana 2 into your application requires a straightforward API call. Here's a complete example using curl:

"https://wisgate.ai/v1beta/models/gemini-3-pro-image-preview:generateContent" \
-H "x-goog-api-key: $WISDOM_GATE_KEY" \
-H "Content-Type: application/json" \
-d '{
"contents": [{
"parts": [{
"text": "Da Vinci style anatomical sketch of a dissected Monarch butterfly. Detailed drawings of the head, wings, and legs on textured parchment with notes in English."
}]
}],
"tools": [{"google_search": {}}],
"generationConfig": {
"responseModalities": ["TEXT", "IMAGE"],
"imageConfig": {
"aspectRatio": "1:1",
"imageSize": "2K"
}
}
}' | jq -r '.candidates[0].content.parts[] | select(.inlineData) | .inlineData.data' | head -1 | base64 --decode > butterfly.png
This command sends a prompt to the Nano Banana 2 model, specifies 1:1 aspect ratio and 2K resolution, and decodes the base64 response into a PNG file. Replace $WISDOM_GATE_KEY with your actual API key. The responseModalities field tells the API to return both text and image data. The imageConfig object controls aspect ratio and resolution—adjust these values based on your template requirements.
