Frequently asked questions

Is Nano Banana 2.1 free to use?

Yes, within limits: Google AI Studio offers free web access, and the Gemini API has a free tier with rate limits — which is what this playground uses with your own key. In the Gemini app, 2.1 requires a paid Google AI plan. There is no charge from this site, ever.

Where do my images and API key go?

Your key is saved in your browser's localStorage only. When you generate, this page calls Google's Gemini API directly with your key, and the image is returned straight to your browser. We run no server that could see either.

How is 2.1 different from Nano Banana 2 and 2 Lite?

2.1 is the flagship of the Nano Banana 2 family: 4K output, 14 reference images, thinking levels and grounding. Nano Banana 2 Lite is the lighter, faster and cheaper sibling, optimized for single-prompt generation rather than multi-reference work.

Can it edit my photo?

Yes — attach up to 14 reference images and describe the change in plain language ("put her in a 1970s London pub, keep the face"). Keeping 4 characters consistent across a set is a documented strength of the 2 series.

Which prompt style works best?

2.1 follows the intent of a prompt well, so natural language beats keyword soup. For shot-by-shot control, start from our 50+ prompt library and edit. Long, highly detailed compositions may still suit Nano Banana Pro — see 2.1 vs Pro.

What does it cost via API?

Google prices Nano Banana 2-family images per image, and 2.1 was announced as cheaper than Pro; third-party host fal lists Nano Banana 2 at $0.08/image vs Pro's $0.15. Full context and cURL examples on our API page.
