Nano Banana 2 is Google’s edit-anything model. Describe the change in plain words and everything else stays intact, up to 4K.
Nano Banana 2 made its name on instruction-based editing: “change the jacket to red, keep everything else” keeps everything else. It accepts up to 14 reference images and outputs anywhere from 0.5K drafts to 4K finals.
It is equally strong as a generator, with an unusually wide aspect ratio set (including 21:9 and auto). A Pro sibling is in the catalog for the highest-stakes edits.

Questions
What makes Nano Banana 2 different from other image models?
Edit fidelity. It changes what you asked and leaves faces, text and backgrounds untouched, where most models regenerate the whole picture.
Do I need a Gemini subscription to use Nano Banana 2?
No. Nano Banana 2 is billed per image in Hiroska tokens; no Google or Gemini account is needed.
When should I use the Nano Banana 2 0.5K tier?
For drafting. It costs less and renders faster, and the same prompt re-runs at 2K or 4K once the composition is right.
