One model for the whole creative process
From a first concept to a coordinated campaign, Nano Banana 2.1 gives you control over the subject, composition and finishing details.
An AI image editor for focused changes
Replace an object, adjust a product or retouch a small area. Upload an image with the target area visibly marked and explain what should change and what should stay. The workspace accepts prepared images; it does not include an in-browser mask brush.
Character consistency AI for visual stories
Carry a recognizable character into a new outfit, pose or setting. Re-upload your chosen result as a reference for each follow-up edit to maintain continuity across a series.
Multi-reference image generation
Combine up to 10 references in Image Edit. Assign a role to each image, such as the person, product, background or visual style, to guide a more deliberate composition.
AI text rendering for readable designs
Create posters, social graphics and infographics with more dependable lettering and layout. Put the exact wording in your prompt and check spelling and placement before publishing.

Nano Banana 2.1 vs Nano Banana 2: what changed?

Nano Banana 2.1 vs Nano Banana Pro: which should I choose?
Choose Nano Banana 2.1 for efficient, repeated generation and editing up to 4K, especially product images and marketing variants. Nano Banana Pro remains an option for work that prioritizes premium creative quality. The right choice depends on your brief, budget and the results you prefer.
Can I generate and edit 4K images?
Yes. Select 1K, 2K or 4K in the workspace for either Text to Image or Image Edit. Higher resolutions use more credits and can take longer. The selected aspect ratio determines the shape of the output.
How many reference images can I use?
Image Edit supports up to 10 JPG, PNG or WebP images, each up to 30MB. Explain what each reference contributes and which details should remain consistent.
How do I make a local or mask-guided edit?
Prepare an image with the intended area visibly marked, upload it in Image Edit and describe the replacement. The model supports marked-area guidance; this workspace does not have a mask drawing tool or a separate mask upload. Review the entire result because unchanged areas are not guaranteed to be pixel-identical.
How many credits does Nano Banana 2.1 cost?
Each generated image costs 15 credits at 1K, 25 at 2K or 35 at 4K. The same rates apply to image editing. Check the total shown in the generator before submitting a batch.
