Nano Banana Pro (Gemini 3 Pro Image)
"Nano Banana Pro" is Google's public nickname for Gemini 3 Pro Image, released as a preview in November 2025 and reaching general availability in June 2026. Unlike a single-purpose diffusion model, it runs on Google's Gemini 3 multimodal reasoning stack — so it can ground an image in real facts pulled via Search (an accurate chart of real data, a correctly structured molecule diagram), follow long multi-part instructions in one pass, and render dense, accurate text and data labels across languages. It is Google's direct replacement for the Imagen line, which is being retired: Imagen 4's endpoints shut down 17 August 2026, with Google recommending migration to this Gemini image family (the cheaper sibling is gemini-3.1-flash-image). Access is via the Gemini app, the Gemini API, or Vertex AI — useful if a lab already runs on Google Cloud/Workspace.
