- "Nano Banana" is the codename for Gemini 2.5 Flash Image, Google's new model for generating and editing images.
- It allows conversational editing, maintains consistency between people and objects, and combines images with natural language instructions.
- Includes SynthID as an invisible watermark and filters for sensitive content and public figures.
- You can test it in the Gemini app and in Google AI Studio using the gemini-2.5-flash-image-preview model.
After weeks of speculation, the nickname «Nano Banana» stops being a mystery: corresponds to Google's new image engine, officially unveiled as Gemini 2.5 FlashPictureThe company is activating a feature that combines generation and editing with a conversational approach that seeks to reduce friction in the creative flow.
The model arrives to compete with generators like Midjourney and with traditional editors like Photoshop, reinforced by improvements in consistency between shots, feature preservation, and a response speed that Google describes as "lightning fast." In addition, It is integrated into the Gemini app and is available through APIs and in Google AI Studio..
What is "Nano Banana" and what does it provide?
"Nano Banana" is the internal name of the model, an evolution focused on text-guided editing and highly controlled generation. The system understands natural instructions and applies changes to the same image, without forcing you to start from scratch each time.
One of its keys is the visual consistency: When you edit a photo, the subject's face, pose, or lighting remains consistent between versions. This reduces distortions or perspective jumps which still appear in other engines in complex scenarios.
El Photorealism takes a step forward with more believable textures and lighting, and Google claims concrete advances in faces and hands, two traditionally delicate areas in image AI. The model also stands out for its speed, which facilitates shorter testing and improvement cycles.
In community benchmarking, such as that of LM Arena, "Nano Banana" appears among the best rated in user experience editing, driven by its balance of quality, control and response speed.
Key editing and generation features
- Conversational editing: dialogues with the image and requests iterative adjustments (e.g., intensifying the sky, changing the color of a car, or adding an object).
- Local selection and retouching: Choose specific areas to erase elements, modify the background, or adjust lighting and color without affecting the rest.
- Composition and mixing: Combines multiple photos into a single scene and applies the style of one image to objects in another.
- Character coherence: Maintains similarity between versions of the same person, pet, or object across multiple edits.
In addition to creative flexibility, Google adds a layer of security: All generated or edited images incorporate SynthID, an imperceptible embedded watermark that resists transformation and allows you to verify whether content has been created or altered by AI.
The system includes filters to prevent the generation or manipulation of sensitive content (violence, explicit nudity) and blocks editing of famous people. If the user uploads a real photo to be altered, security mechanisms attempt to prevent requests that could lead to deepfakes.
In practice, this means less time wasted on technical testing and more focus on the creative outcome: Natural language commands become actions on the scene with greater semantic precision and respect for scale, depth and style.
How to use Nano Banana in the Gemini app and AI Studio
Experience is integrated into the Gemini interface, without the need for additional software. In many cases You can take advantage of it even in the free version, depending on the deployment in your region and account.
- On the Gemini app or website: Accede to gemini.google.com/app (o the mobile app), select the available template and go to “Create images” under “Tools”.
- Generate or edit: Type a prompt to create from scratch or upload a photo to edit. You can add chained instructions to fine-tune the result over multiple rounds.
- Useful orders: “make the shot black and white”, “remove the object from the background”, “change the background to a cityscape” or “apply the style of this image to this dress”.
If you prefer to validate that you are using the correct model from the developer environment, Google AI Studio offers a direct flow for controlled testing with gemini-2.5-flash-image-preview.
- Sign in to Google AI Studio.
- Choose the "gemini-2.5-flash-image-preview" model in the selector.
- Enter text prompts and/or upload images to see edits in real time., with support for multi-shift editing.
While the behavior has improved in consistency and photorealism, it is worth remembering that The representation of text within images or certain complex reflections may not be perfect yetStill, language-driven editing and watermarking provide an interesting balance between creative control and responsibility.
With its combination of conversational editing, character consistency, speed, and safeguards like SynthID, "Nano Banana" fits as a versatile option for creators, brands and users who want to adjust photos or compose scenes without complicating themselves with masks and layers.: all from Gemini itself and with a flow that encourages iteration until finding the version that best fits the original idea.
