Nano Banana Pro (Gemini 3 Pro Image) now available in the AI Gateway
By Steven Van ·
Google's Gemini 3 Pro Image model is now available through Vercel's AI Gateway without a separate provider account.
Vercel's AI Gateway now supports Nano Banana Pro (Gemini 3 Pro Image) with no separate Google provider account required. The model is aimed at more advanced use cases than the original Nano Banana, adding diagrams with accurate labeling, integration of web search information for images with up-to-date details, higher resolution output, and higher multi-image input limits for compositing.
To use it with the AI SDK, developers set the model to google/gemini-3-pro-image. Since it's a multi-modal model, image generation runs through generateText rather than a dedicated image-generation call.
