Frequently Asked Questions

Nano Banana is Google's Gemini 2.5 Flash Image model in the Gemini app and Google AI Studio. It is strong at conversational edits, character consistency and multi-image fusion from an uploaded face.

Yes. Use them on photos of adult men. Do not run them on pictures of minors, and do not ask the model to de-age an adult into a teen look.

These jobs ask the model to keep the uploaded face and skip celebrity likeness. If a result looks like a famous actor, rerun and say keep his real face, no lookalike.

Reuse the same [YOUR PHOTO] and say keep his exact face, age and hair. Nano Banana can hold a character across turns if you keep that lock in each new scene.

No. This page stays on studio, street, professional, editorial and workshop stills with ordinary clothes. Fully clothed, workplace or public settings only.
