What is Nano Banana 2.1?

Nano Banana 2.1 is an update to Gemini 3.1 Flash Image (Nano Banana 2). Google describes it as its latest high-efficiency model for image generation and conversational editing: Flash-level speed and cost, with clear gains in visual quality, prompt adherence, multi-turn character consistency and text rendering. It keeps up to four characters and ten objects consistent, and fixes the tiling artifacts Nano Banana 2 showed in panoramic ratios at 2K and 4K.

In Google’s own human-preference evaluation on its model card, Nano Banana 2.1 scored 1050 overall, ahead of Nano Banana 2 (990) and Nano Banana Pro (935). Google also lists its limits: small text is often blurry at 1K, and long paragraphs remain hard. On ImgAI it accepts up to 14 reference images, outputs 1K, 2K or 4K in 14 aspect ratios, and costs 22–58 credits per image.

Nano Banana 2.1 prompt tips

These come from real generations — read them alongside the original prompts in the examples.

  1. Use 2K for small text

    Google notes small text can blur at 1K. If your image has captions or labels, render at 2K or 4K.

  2. Keep text short and quoted

    Put each title or label in quotes. Long paragraphs are still a weak spot for the model.

  3. Describe characters once, precisely

    Give each character a fixed look ("red beanie, round glasses") and say "keep both characters identical" for multi-panel work.

  4. Edit with references, one change at a time

    Upload the earlier image and change one thing per request; the model is built for multi-turn editing.
