Nano Banana 2.1 is Google's high-efficiency AI image generation and conversational editing model. It works best when you describe a picture the way you would explain it to a friend. Nano Banana 2.1 follows long, detailed prompts closely, so plain and specific words get the best results.
In OpenArt, you set the resolution, aspect ratio, and number of pictures with the controls under the prompt box. Your Nano Banana 2.1 prompt can focus on the picture itself.
Describe the whole scene in full sentences
A good Nano Banana 2.1 prompt names the subject, the setting, the light, and the style. Write it as one or two full sentences.
"Coffee, cozy, aesthetic" leaves Nano Banana 2.1 guessing. "A white mug of coffee on a wooden windowsill, soft morning light, rain on the glass, realistic photo" gives Nano Banana 2.1 a clear picture to make.
Put exact words in quotation marks
Nano Banana 2.1 writes readable text inside a picture when you put the words in quotes. Say where the words go and how big they should be, such as "a bold headline at the top."
Keep the text in a Nano Banana 2.1 picture short, like a title, a price, or a few labels.
Give every reference image a job
Nano Banana 2.1 takes up to 14 reference images, with up to 4 people and up to 10 objects in one picture. Tell Nano Banana 2.1 what each photo is for, such as "image 1 is the woman, image 2 is the jacket, image 3 is the room."
Use clean, well-lit reference photos, and show a product from more than one angle when the label matters.
Name what must stay the same across a batch
When you make a series in Nano Banana 2.1, list the details that cannot change. Name the label color, the logo spot, the face, or the outfit in every prompt.
Repeating those details keeps a Nano Banana 2.1 batch looking like one set.
Edit one change at a time
To edit a picture in Nano Banana 2.1, upload it and type only the change you want, like "make the sofa dark green." Add one short line about what stays, such as "keep the room and the lighting the same."
Small, single changes keep the rest of a Nano Banana 2.1 picture as it was.
