Nano Banana 2.1 image generation and editing
Nano Banana 2.1 is an image generation and editing mode inside ImageFk. Use a text prompt to describe a new image, or upload reference images when the subject, product, character, layout, or visual direction needs to stay recognizable. The workspace supports 1K, 2K, and 4K output sizes, so you can choose a faster draft or a larger result for closer inspection.
This page describes an integrated ImageFk model option. It is not an official model-provider product page. Provider availability, output behavior, processing time, and supported controls can change, so review the result and the current terms before using it for important work.
How to use Nano Banana 2.1
- Choose the model. Select Nano Banana 2.1 in the ImageFk image workspace.
- Add a prompt. Describe the subject, composition, lighting, style, text, materials, and details that matter.
- Upload references when useful. Reference images can help guide a product, person, scene, or visual style. Only upload images you are allowed to use.
- Choose an output size. Use 1K for quick exploration, 2K for a balanced result, or 4K when extra output size is useful.
- Compare and refine. Review the result, keep what works, and change one part of the prompt at a time.
What Nano Banana 2.1 is useful for
Nano Banana 2.1 can help with concept images, product visual variations, reference-guided edits, social graphics, character or scene exploration, background changes, and other prompt-led image tasks. It is especially useful when you want to start from an existing image rather than describe every visual detail from an empty canvas.
For product images, keep the original product photo and inspect labels, measurements, logos, colors, and proportions. Generated images can alter small details even when the main subject looks convincing. For portraits and real people, use images with permission and review identity-sensitive changes carefully.
Prompt tips
Start with the main subject and the requested action. Then add the setting, composition, camera viewpoint, lighting, materials, and constraints. State what must remain unchanged when editing a reference image. Avoid combining unrelated jobs in one prompt. A focused instruction such as “keep the bottle shape and label unchanged, replace the background with a clean warm studio surface, and add a soft natural shadow” is easier to review than a long list of competing changes.
Output size and credits
ImageFk currently prices Nano Banana 2.1 by output size: 1K uses 2 credits, while 2K and 4K use 3 credits. The final amount is shown by the workspace and account state at generation time. A larger output does not guarantee that every generated detail is accurate, so quality review remains necessary.
