Google has just rolled out a significant upgrade to its Gemini app’s image editing features, introducing a new model—officially called Gemini 2.5 Flash Image and colloquially dubbed “Nano-Banana.” This latest DeepMind-powered model excels at preserving the likeness of people and pets across transformations, enabling users to apply outfit changes, blend images, switch backgrounds, and even multi-turn fine edits with impressive consistency—all while maintaining character recognition. Users can also input multiple images for seamless blending, apply one image’s style to another, and generate videos from edited outputs. To enhance transparency, every AI-generated or edited image now includes a visible watermark plus an invisible SynthID digital watermark.

Key Takeaways
– The “Nano-Banana” upgrade (Gemini 2.5 Flash Image) focuses on character consistency and nuanced, multi-step edits using both text and image prompts.
– Users can now blend, restyle, or embed subjects—like people or pets—into new settings (e.g., new outfits or locations) while keeping them recognizable.
– All outputs bear both a visible watermark and an invisible SynthID marker to signal AI origin and support content authenticity.
In-Depth
Google’s latest Gemini image upgrade—affectionately known by its playful internal codename “Nano-Banana”—marks a thoughtful step forward in AI-powered photo editing.
The new Gemini 2.5 Flash Image model, developed by DeepMind, disproportionately prioritizes accuracy in preserving recognizable features of people and pets during edits. That means you can play around with styles—trying out retro beehive hairdos, tutus, or wild backgrounds—and still end up with a subject who clearly resembles who they started as. Importantly, blending imagery has never been smoother: you can merge multiple photos or overlay styles, like “dress this pair of rain boots in the texture of butterfly wings,” and trust the coherence of the result.
What sets this update apart is its multi-turn editing capability—meaning you can tweak a scene step by step without losing the integrity of earlier edits. Perhaps most commendable from a responsible standpoint: transparency. Every image carries both a visible watermark and an embedded SynthID tag to indicate AI origin. That avoids the all-too-common trap of misleading visual manipulation, giving users creative freedom while fostering authenticity.
In a landscape where AI can easily drift from innovation into misrepresentation, Google’s conscious choice to balance advanced creative tools with robust safeguarding reflects a prudent, measured approach. If you’re experimenting with generative visuals or enhancing personal photos, Gemini’s reliable edits—backed by character consistency and ethical safeguards—are a welcome boost in the right direction.
