Nano Banana Pro (Gemini 3 Pro Image) (Nano Banana Pro) is Google's advanced native image generation model built for professional and creative workflows, with accurate diagram labeling, web-search-grounded imagery, and higher resolution output.
import { generateText } from 'ai'
const result = await generateText({ model: 'google/gemini-3-pro-image', prompt: 'Render a picture of a red balloon.',});Nano Banana Pro (Gemini 3 Pro Image) (internally codenamed Nano Banana Pro) is Google's image generation model for professional and creative use cases that demand more than basic image synthesis. It has three headline capabilities: accurate label generation in diagrams and charts, integration of Google web search to ground images in up-to-date real-world information, and higher resolution output with higher multi-image input limits for complex compositing.
The diagram and labeling capability is particularly significant for technical teams. Generating an architectural diagram, data pipeline schematic, or annotated system map with accurate text labels has historically been a weak point for image models. Nano Banana Pro (Gemini 3 Pro Image) handles these workflows directly.
Unlike dedicated image generation APIs, Nano Banana Pro (Gemini 3 Pro Image) is a multimodal model that outputs both text and images through generateText. A single request can return a written description, a diagram, and explanatory annotations together. This makes it suitable for documentation generation, creative briefing, and technical illustration workflows where you need mixed-media output.
