Nano Banana 2.1: 15 Prompts with Results (Polish & English)

👁 125 reads

15 prompts we ran through Nano Banana 2.1 on launch day - each with an image, Polish and English versions, and a brief assessment. We tested Polish diacritics, precise scene layouts, the same character in four locations, and photo edits with masks. Everything about the model is in our Nano Banana guide.

As of October 7, 2026

  • Model: Nano Banana 2.1 (gemini-nano-banana-2.1), launched October 6, 2026.
  • Generated via OpenRouter API, default thinking level (medium), no refinements and no cherry-picking from multiple outputs.
  • Cost: $0.035-$0.054 per 1K-2K image, $0.117 for 4K.
  • In the Gemini app you can paste the Polish version - it works the same.
  • Each image is the first attempt. We didn’t generate multiple versions to show the best one.
  • The English version is exactly what we sent to the API. The Polish version is faithful, ready to paste into Gemini.
  • Text that should appear in the image stays in quotes and in Polish in both versions.
  • For edits (12-15) we attached a bakery photo or portrait as reference - without it the prompt makes no sense.

What We Learned from These 15 Tests

  • Text in quotes comes out letter-perfect, including difficult Polish diacritics like “Źdźbło i żółć“. Keep them in Polish even in English prompts.
  • Percentage-based layouts are treated loosely by the model. Simple scenes (water ad) come out perfect, cluttered ones (kitchen) don’t.
  • Character from reference holds up very well if you list the features to preserve in your prompt. Fine details (which ear has the earring) can get lost.
  • Mask as second image improves edit quality (9.0/10 for us vs. 7.7/10 with description alone), but isn’t a hard boundary.
  • The model likes to add details: brands on packaging, stamps, extra decorations. If you don’t want them, add “no other text or logos”.

Numbers from full tests and comparison with the predecessor are in the news post about the Nano Banana 2.1 launch, and the showdown with the leaderboard leader in Nano Banana 2.1 vs GPT Image 2.5. Older prompts for the previous version: 10 prompts for Nano Banana 2.
