Nano Banana Pro

Nano Banana Pro is Google's marketing name for Gemini 3 Pro Image (gemini-3-pro-image), launched November 20, 2025. Built on the Gemini 3 Pro reasoning engine, it 'thinks' through composition before rendering, producing notably higher-fidelity output than the fast Flash-line models. Standout features: native 1K/2K/4K output, legible multilingual text rendering for posters and infographics, up to 14 reference images with character consistency across five people, conversational multi-turn editing, and Google Search grounding so generated graphics can reflect real-world facts. It's available in the Gemini app, Google AI Studio, Vertex AI, and across Workspace (Slides, Vids, NotebookLM).

The honest picture: it's the expensive, slow option in Google's lineup — the newer Nano Banana 2 (Gemini 3.1 Flash Image) is the default in the Gemini app and roughly half the price per image. Free-tier users get about 2 images a day at 1K with a visible watermark, and all outputs carry Google's SynthID watermark. Note the confusing naming: despite the numbering, Nano Banana 2 is newer than Nano Banana Pro.

Use in the Gemini app (Create images with the Thinking model), Google AI Studio, the Gemini API, or Vertex AI.
