Nano Banana (Gemini): AI Image Generation and Editing

Nano Banana is the nickname Google has given to Gemini 2.5 Flash Image, an advanced AI image generation and editing model. This model was officially announced on August 26, 2025, as part of the Gemini ecosystem (from Google DeepMind). According to Google, Nano Banana “allows a single photo to be converted into countless new creations” based on natural language instructions. It is designed to create photorealistic illustrations or modify existing photographs with simple prompts, thanks to its contextual understanding and real-world knowledge.

Nano Banana is already integrated into the Gemini platforms: it can be used directly from the Gemini mobile application (Android/iOS) and the Google AI Studio website, without the need to install additional software. Google emphasizes that images generated or edited with Nano Banana comply with the company’s responsible AI principles: they carry an invisible SynthID digital watermark (in addition to a visible logo) to clearly distinguish them as AI-generated content.

Unlike more basic editors or simpler models, Nano Banana uses the reasoning capabilities of the Gemini models (including their world knowledge) to maintain the visual coherence of scenes and characters. For example, the official launch explains that the new model has a special focus on maintaining a person’s appearance when changing outfits or backgrounds, so that “the photo always looks as it is.”

AgentAya Verdict: Nano Banana

Nano Banana (Gemini 2.5 Flash Image) is presented as a practical and powerful solution for SMEs and entrepreneurs who need to quickly generate professional-looking visual content. By relying on Gemini’s conversational interface, it eliminates the dependence on complex software or external designers. Google exemplifies creative scenarios (placing oneself in a new background, changing outfits, combining scenes) that previously required editing expertise; now, it is enough to ask for it with text.

This allows small businesses to create ads or marketing material without specialized design knowledge. For example, Google Workspace highlights that Nano Banana integrated into Slides is a “game-changer for creative teams” that need to edit photorealistic images instantly.

Its strong point is photorealistic editing guided by natural language: it is enough to indicate what to change (“change the background to the beach and add a hat”) and the model applies the transformations while preserving the rest of the image. Likewise, the visual quality is very high thanks to the model’s size and capability; Google highlights its level of improved precision and realism compared to previous versions.

On the other hand, Nano Banana is not intended to replace professional editing software with absolute control. For tasks that require meticulous editing (for example, exact architectural designs or technical graphics) or very specific styles, dedicated tools like Photoshop or Illustrator remain more appropriate. Nor is it ideal for massive flows of generating thousands of images with an identical style, as Nano Banana is designed for specific or iterative edits rather than automated mass production. In summary, it is excellent for quick creations and marketing visual concepts, but it does not replace complex professional graphic design processes.

Main Features of Gemini

• Image generation from text: converts prompts into illustrations or realistic photos.
• Conversational editing: allows modifying elements, backgrounds, or colors with written instructions.
• Visual consistency: maintains the coherence of characters, objects, or products between versions.
• SynthID watermark: inserts invisible identification into AI-generated images.
• Multi-platform access: available via the web (AI Studio) and mobile (Gemini app).
• Synchronization with Google Drive and Photos: allows easy saving and sharing of images.

These functions allow SMEs to save time and money by automating the creation of marketing materials, product prototypes, or social media posts.

AI Functions

Nano Banana is based on the Gemini 2.5 Flash Image model, which combines contextual reasoning and visual comprehension. Its AI analyzes natural language instructions and translates them into coherent and detailed images.

What is truly “intelligent” is its semantic editing capability: it understands the context (“make the person smile,” “change the background to a beach”) and applies the changes without affecting the rest of the composition. It can also combine several images, generate photorealistic portraits, color old photographs, or create stylized versions. This deep visual understanding distinguishes Nano Banana from simple automatic editors or basic text-to-image generators.

Integrations

The tool integrates naturally with the Google ecosystem. Projects can be saved to Google Drive, edited from Google Photos, or exported to Docs and Slides for use in presentations.

For developers, there is an official Gemini API and support in Vertex AI, which allows for automating image generation within applications or marketing systems. Furthermore, its compatibility with Firebase and Google Cloud facilitates collaborative flows or use in mobile apps.

These integrations make it especially attractive for SMEs already operating with Gmail, Workspace, or Drive, simplifying technological adoption.

Security and Data Compliance

As a Google product, Nano Banana complies with the company’s privacy and security standards. Google explains that the model is delivered “within our AI Principles,” applying transparency mechanisms: all images include a visible watermark and the SynthID digital mark to distinguish them as AI-generated. According to Google, this helps clearly identify AI content at the time of its creation. Regarding privacy, the Gemini policy indicates that Google may use the generated data (prompts and images) to “maintain and improve” its AI services.

In fact, official notices clarify that user data may contribute to future model training (unless the user deactivates it). However, the user retains ownership of their original images and can manage or delete their data from their Google account. In practice, processed images are sent and stored on the Google Cloud infrastructure, which encrypts data in transit and at rest according to its security standards (general Google Cloud information, not specific to Nano Banana). Google does not publish additional details about specific GDPR certifications for Nano Banana but does state that the services follow the general Google Cloud/AI privacy policies.

In summary, every generated image is marked for transparency, and the data policy indicates that Google will use the information to improve its AI unless the user chooses otherwise. There is no evidence of improper data use beyond these standard policies.

Language – Customer Service and Interface

Google offers documentary support, forums, and guides in Spanish, in addition to technical support in several languages. Although the main AI Studio interface is in English, community support and translated tutorials facilitate use for Spanish speakers. Users can access help through the Gemini community and Firebase forums, where they can find a quick response and plenty of online documentation.

AI Language – The Tool Itself

The Nano Banana AI supports at least 45 languages, as indicated by Google in its communications. Furthermore, Gemini’s image generation function is enabled in all languages supported by the Gemini application in that country. In practice, this means that instructions can be given in Spanish naturally, and results comparable to other languages can be obtained, thanks to the model’s multilingual capability.

Mobile Access

Nano Banana is fully available on the Gemini mobile app (Android and iOS). Google instructs that generating or editing images requires a few simple steps: “go to gemini.google.com or open the Gemini mobile app” and write your request. All main functionalities (uploading photos, writing prompts, adjusting results) are in the app. Mobile use replicates the experience of the web version and, being linked to the user’s Google account, allows a project to be started on the phone and then continued on the PC (projects are saved in the cloud). This mobility makes it easy for entrepreneurs to create content anywhere.

Support, Onboarding Process, and Account Management

The onboarding is practically automatic: only logging in with a Google account is required. Google AI Studio offers interactive tutorials and example prompts for beginner users.

No installation process or technical knowledge is necessary, so an SME can start generating content in minutes. The online guides cover everything from basic use to API integration, facilitating progressive growth according to needs.

Ease of Use / UX

The interface is one of Nano Banana’s greatest strengths. Everything is based on a simple visual flow: write an instruction, review the result, adjust, and save.

It does not require graphic design knowledge or technical commands; the learning curve is practically zero. This explains its popularity among non-technical users and small teams that need quick results without relying on prior training.

Pricing and Plans

Basic access to Nano Banana is free through the Gemini app or Google AI Studio. Any user with a Google account can generate and edit images at no cost.

For developers or companies that wish to integrate it via API, a pay-per-use model applies within Google Cloud: approximately $30 USD per million generated tokens, which amounts to a few cents per processed image.

This scheme makes the operational cost extremely low and predictable, ideal for startups or businesses seeking economic efficiency.

Case Study

An artisan clothing store in Buenos Aires used Nano Banana to generate product images without photo shoots. The owner uploaded a single photo of the item and asked the AI to change the background to different scenarios (beach, forest, professional studio) in a matter of seconds.

The result: they reduced photography costs by 80% and doubled the production of content for social media in one week. This type of case demonstrates the tangible value that tools like Nano Banana can bring to creative SMEs and local entrepreneurs.
