Nano Banana Pro is Google DeepMind’s Gemini 3 Pro Image model, reachable inside the Gemini app and Google AI Studio. It generates or edits images from 512 px up to 4K from text, reference images or both, and its headline trick is accurate, readable text in many languages – mockups, infographics, posters and multi-image montages come out usable rather than garbled.
Editing keeps subjects consistent across multiple images, and controls cover lighting, focus and colour for campaign-style output. The free Gemini tier includes limited Pro-image attempts, while Google AI Pro (from $19.99 per month) unlocks higher limits and faster generation – the same plans that cover Gemini and Veo, so one subscription spans chat, images and video.
