Nano Banana 2.1

Nano Banana 2.1 is a browser-based AI image generator and editor at nanobanana21.com that builds on Nano Banana 2, accepting text prompts plus up to 14 reference images and returning finished pictures at 1K, 2K or 4K with legible text rendered inside the frame.

What is Nano Banana 2.1?

Nano Banana 2.1 is the upgrade listing for Nano Banana 2, which the page identifies as Gemini 3.1 Flash Image, and the all-round Nano Banana model for creating and editing images. You type a prompt, optionally upload up to 14 reference photos of people, products or places, choose an aspect ratio and a resolution, and the generator returns a finished image; nothing is installed and the whole tool runs in the browser. The page is explicit that the generator itself currently opens on Nano Banana 2, with Nano Banana Pro, Nano Banana 2 Lite and the original Nano Banana selectable from the same model picker.

What makes Nano Banana 2.1 stand out?

• Up to 14 reference images — upload a person, an outfit, a pet and a chair, then describe the scene; Google states Nano Banana 2 keeps up to five characters and 14 objects consistent within one workflow, so the people and products in the result still resemble the uploads.
• Readable text inside images — headlines, labels, menus and packaging copy render cleanly when written in quotes in the prompt, and an existing image can have its text rewritten into another language while the layout stays put.
• 14 aspect ratios, 1K to 4K — ratios run from a tall 1:8 banner to a wide 8:1 strip, plus everyday 1:1, 9:16 and 16:9; 1K is available on any account, while 2K and 4K require a paid plan.
• Four models in one picker — Nano Banana 2 (default, 8 credits per 1K image), Nano Banana Pro (20 credits, up to 8 references), Nano Banana 2 Lite (4 credits, 1K only) and the original Nano Banana (4 credits) all sit in the same menu.
• Single-photo editing — upload one picture and describe only the change (a new background, a different outfit, a cleaner table); everything you do not mention stays as it was.
• Quoted exact words with placement — put text meant to appear in the image in quotes and state where it goes, such as a headline at the top or a label on the bag.
• Agent mode — describe an idea in a conversation and keep refining it; free accounts get 10 agent messages a day and paid plans lift the daily limit.

Who should use Nano Banana 2.1?

• Online shop owners — upload a product photo alongside prop or mood images and produce a styled listing image where the product still matches the real item.
• Comic artists and storyboarders — reuse a single character reference across panels so the same face, hair and outfit carry from a bus stop to a library door.
• Packaging and ad designers — upload finished artwork and request the copy in French, Spanish or Japanese while layout, colors and photography stay unchanged.
• Social media managers — generate one idea as a square post, a 9:16 story and a 16:9 cover, then download each at the size that feed needs.

How does the Nano Banana 2.1 generator work?

The workflow has four steps. Describe the image, including any words that should appear in it. Add up to 14 references and refer to them as Image 1, Image 2 and so on in the prompt to say what goes where. Choose the model, aspect ratio and size. Generate, compare against your references, adjust one prompt line if needed, and download.
