The tool is designed to deliver more natural edits by keeping people, pets and objects consistent across different scenarios. To showcase its ability, Pichai shared a set of AI-generated photos of his dog Jeffree on International Dog Day. The images reimagined Jeffree as a surfer, a cowboy, a superhero and even a chef.

“Our image editing model is now rolling out in @Geminiapp – and yes, it’s 🍌🍌. Top of @lmarena’s image edit leaderboard, it’s especially good at maintaining likeness across different contexts. Check out a few of my dog Jeffree in honor of International Dog Day – though don’t let these fool you, he definitely prefers the couch:),” Pichai wrote in his post.

How Google’s Nano Banana (Gemini 2.5 Flash Image) works

According to Google’s blog post, users can upload a photo, describe the changes they want, and Gemini will generate a new version while preserving the original likeness. The tool supports:

Costume and background changes, such as placing a person in different outfits, jobs or eras.

Photo blending, like merging a person and their pet into the same frame.

Step-by-step edits, including adding or removing objects while redesigning a space.

Design mixing, where patterns or textures from one photo can be applied to another.

To ensure transparency, all AI-generated or edited photos carry a visible watermark along with Google’s invisible SynthID digital marker. The Nano Banana feature is available starting today in the Gemini app.
