Review: Google’s Nano Banana (Gemini 2.5 Flash Image) — What the Tests Reveal

on 56 years ago

1. Official Overview & Capabilities

According to Google’s dev blog, Gemini 2.5 Flash Image, nicknamed nano‑banana, brings several major leaps forward:

  • Multi-image fusion: Merge images seamlessly into one.
  • Character consistency: Preserve the same face or object across different scenes.
  • Prompt-based editing: Make precise local edits—remove stains, blur backgrounds, change poses, and more.
  • World knowledge: Leverage contextual understanding for educational or diagram-based tasks. Templates facilitate rapid app creation in Google AI Studio.
