Three steps take you from a prompt to a finished image.
Nano Banana 2.1 FAQ
Quick answers about running Nano Banana 2.1 on OpenArt.
What resolution and aspect ratios does Nano Banana 2.1 support?
Every model on OpenArt ships with a range of sizes and frame shapes, and Nano Banana 2.1 reaches the highest tier at 4K.
How many reference images can I add to one prompt?
You can attach as many as 14 reference images to a single prompt, and the model merges them with your written directions in a balanced way.
How many images can I generate from one reference?
One uploaded reference can seed as many as forty variations, and each of them keeps the same look.
Can it render accurate, readable text inside images?
Yes. Lettering comes out crisp and correct, so product labels, menus, and street signs stay legible in the final shot.
Does editing by chat affect the rest of the picture?
No — a tweak such as a new shirt color, a swapped outfit, or smoother skin texture lands exactly where you want it, and the surrounding scene is left alone.
Which plan do I need, and do credits roll over?
Starter, Plus, Pro, and Wonder plans all cover model access, and the pricing FAQ explains credit rollover, monthly versus annual plans, upgrades, downgrades, and cancellation.
