🚀 What is Gemini Nano Banana?
Google’s Gemini Nano Banana (part of Gemini 2.5 Flash Image) is an AI image model inside the Gemini app. It lets you transform your photos into 3D-looking figurines, avatars, or toy-style models in seconds. Since its launch, millions of users have used it to generate hyper-realistic edits, collectibles, and even figurine-painting videos.
⚠️ Note: Nano Banana produces 2D images that look 3D — it does not output true 3D mesh files (like OBJ/GLB). If you need printable or animated meshes, you’ll need photogrammetry tools such as Reality Capture or Metaphase.
