From our tests

Strengths and limits

  • Clean text in posters and infographics, first try, in our tests.
  • Up to 14 reference images — combine people, products and places in one edit.
  • Edits that keep face, pose and light when you say so (see the gown edit).
  • Fast version at 8 credits for drafts.
  • Long layouts can slip: our infographic repeated one step title — check text before you publish.
  • On Kenerate it currently returns square images whatever size you pick (a fix is in progress) — crop, or use Seedream 5.0 Lite for other shapes and 4K.
  • Closed model: Google's filter applies and may refuse some prompts.

Nano Banana 2 keeps Google's content filter, so explicit prompts are refused. For adult art, use open models on the uncensored AI image generator (18+).
