Consistent Character AI: Keep Up to 4 Characters the Same
Keeping the same face from one image to the next is one of the most common asks from creators. Nano Banana 2.1 takes up to 4 character references and holds their features steady as the scene, outfit or pose changes. In Google's own human-preference tests, multi-character consistency is one of its biggest gains over earlier versions.
Same Face, New Scene
Upload one clear portrait and place that person in a café, on a stage or in a product shot. Face shape, hairstyle and skin tone carry over, so a series of images reads as one character, not a set of lookalikes.
Group Shots with Up to 4 Characters
Add a reference for each person and describe who stands where and what they're doing. Naming each character in the prompt helps the model keep faces from blending together in busy scenes.
Combine Images AI: Up to 14 References in One Scene
Nano Banana 2.1 doesn't paste pictures side by side. It reads up to 14 references, 10 objects and 4 characters, and draws one new image where they share the same light, perspective and style. Think of it as an AI image combiner that builds a scene, not a collage.
People and Products in One Shot
Put a model, a bag and a pair of shoes into one lifestyle photo without a shoot. Each item keeps its shape, color and label. For catalog work, see .
Outfits, Props and Locations
Combine photos of a jacket, a hat and a street corner, then describe the moment you want. The model fits the clothing to the character and places everyone in the location.

Change One Thing, Keep Everything Else the Same
To change one part of an image, describe it in plain words: what to change, and what should stay as it is. For example, "Change her hair to a short platinum bob; keep the face, the clothes, and the room." Google lists mask-based editing among the main improvements in 2.1, and on Topview you make those changes by describing them. If you'd rather brush over an area, try .
Multi-Round Edits Without Drift: What Testers Found and How to Avoid It
Many rounds of edits can still wear an image down. Public tests shared after launch found that Nano Banana 2.1 redraws the whole frame on each edit, so parts you didn't ask to change can slowly shift. One independent test saw colors in untouched areas drift toward pink after eight rounds. These are findings from user testing, not Google's claims. Five habits help:
Go Back to the Original Every Few Rounds
Instead of editing an edit of an edit, return to your first image and apply the changes you've settled on from there.
Turn a Video or YouTube Link into Thumbnails and Posters
Nano Banana 2.1 can use a video or a YouTube link as a reference, not just still images. For creators who already have footage, that's a quick path from a clip to the artwork around it.
YouTube Thumbnail
Paste the video link and describe the thumbnail: the key moment, the expression, the title text. The design stays tied to what's actually in the video.
Movie-Style Poster
Use a trailer or a short clip as reference to build a poster with the same characters, mood and color palette.
