In recent months, there has been a lot of talk aboutNano Banana (code name) on social media, blogs, and the AI community. But what exactly is it? In short: it is the latest model for editing and generating images developed by Google, officially known as Gemini 2.5 Flash Image.
What makes it truly revolutionary is the ability to edit photos with a text command (“add this”, “change that”) while maintaining context, character consistency (faces, proportions, physiognomic features), lighting, backgrounds, etc., even across multiple subsequent edits. Just as if Photoshop were not just a manual tool, but an ally that understands what you want to do and applies it well.
How it works
Here are the main features that make Nano Banana similar, but also superior in some ways, to what many people do with Photoshop:
- Natural language editing
Just write what you want to change (“remove the background,” “add a smile,” “change the color of the dress,” “place that subject in another context”) and the AI interprets it all. - Character and identity consistency
Even after multiple edits, the subject remains Recognizable: features, expressions, proportions, etc. are not "distorted" as often happens with other AI models. - Context and scene preservation
Lighting, background, texture, general atmosphere: everything remains consistent, even if you change specific elements. For example, you can change outfits without altering the lighting mood, or move objects while maintaining perspective and shadows. - Subsequent iterations and multi-turn editing
You can work on an image, modify something, then request another change while remaining on the previous iteration: the AI remembers the context and the changes made. This is what gives the "living" effect, in which the image evolves but does not disconnect from what was before. - Practical use / availability
It is integrated into the Google Gemini app.
N.B.All images created or edited in the Gemini app include a visible watermark to demonstrate the manipulation performed by AI.
Concrete examples
- A portrait edited to change the background but maintain the expression, lighting, and proportions of the face.
- A scene where an object is inserted or removed while maintaining consistent shadows.
- Slight stylistic transformations (e.g., changing outfits or colors, transforming a daytime scene into a nighttime scene).
- Interventions on multiple subjects. in the same image (e.g., multiple people) to ensure they remain consistent.

How to Access and Try Nano Banana
There are three main ways to use Nano Banana:
- Official Website — Visit nanobanana.ai for official information, demos, and resources.
- Integrated with Gemini — Nano Banana is also available within the Gemini interface. In the Gemini UI, the option may appear as Nano Banana or Gemini 2.5 Flash. Depending on the offer. Some advanced features may be reserved for paid plans.
- Try it for free with AI Studio — if you want to test it without subscribing to a plan, you can use aistudio.google.com, the platform that lets you try Google models with limited free credits (but often enough for numerous tests).
Quick steps to try it for free on AI Studio
- Sign in with your Google account at aistudio.google.com.
- Create a new project (or open an existing one): in the dashboard, choose to start an experiment or a test session.
- Select the model: Search for “Nano Banana” or “Gemini 2.5 Flash Image” in the list of available templates and select it for your session.
- Check Credits: AI Studio provides a number of free credits for new users; the project page shows how many credits remain and the estimated cost per request. Use test prompts to evaluate capabilities without running out of credits right away.
- Perform Text Edits: Upload a test photo and tell it what to change (e.g., “remove the background,” “change the color of the dress,” “add a smile”); watch as the model applies the changes while maintaining context and consistency.
- Iterate in Multiple Rounds: A good practice is to work in stages—make a change, evaluate the result, then request the next iteration while maintaining context. This shows the “living” effect of Nano Banana.

Practical Tips
- Read the limitations and credit information before starting to avoid unexpected costs.
- For best results, provide clear prompts and, if possible, visual cues (e.g., "keep this expression," "use the same lighting").
- Remember legal and ethical issues: obtain consent from the subjects portrayed before generating or editing large-scale images.
Limitations and Considerations
Nothing is perfect: a few points to keep in mind:
- There may be cases where tiny details (“micro-textures,” very precise reflections) are not perfect and require manual intervention.
- In complex scenes with many subjects/characters/objects, the AI can get confused about what exactly to change.
- Resolution: Even if the model supports high-quality output, on certain very large formats, there may be loss or need for upscaling.
- Ethical and copyright issues: Recognizing the AI generation, responsible use of images, preserving the consent of the people portrayed if used as “models.”
Conclusion
Nano Banana represents a paradigm shift: It's not just another retouching tool, but a neural interface that allows you to "talk" to the image. If Photoshop was the tool that empowered the designer, Nano Banana opens the door even to those who don't know how to use layers, masks, or brushes, making sophisticated editing accessible with simple commands.
It could change the way we do visual storytelling, marketing, branding, fashion, and social media content production: faster, more experimenting, fewer technical barriers.
