If your social media feeds have been anything like mine lately, they must be flooded with AI-generated images ranging from photorealistic portraits to stylized digital art. With tools that can turn a casual selfie into a cinematic scene or a pet photo into a magazine-style cover, generative image models make complex edits accessible to anyone.
The underlying models behind this trend, such as diffusion-based systems and transformer architectures, have evolved rapidly. They can now perform detailed image transformations that used to require advanced design tools or manual editing skills. Here’s how a single portrait can be modified with just a few well-phrased prompts:
Prompts:
Van Gogh style: “Transform this portrait into a Van Gogh painting in the style of Starry Night, keeping the facial features recognizable.”
Anime character: “Render this person as a high-quality anime character with clean line art and vibrant colors.”
Oil painting: “Convert this image into a realistic oil painting with visible brush strokes.”
Sun glasses: “Add stylish black glasses to the person’s face.”
Formal blue shirt: “Change the t-shirt to a blue formal shirt.”
One of the most impressive tools powering this magic is known by its catchy codename, “Nano Banana.” Officially, it powers the new image editing features in Google’s Gemini 2.5 Flash, representing a significant leap forward in our interactions with AI. In this newsletter, we’ll dive deep into the fascinating technology that allows it to create and edit photos with surgical precision.
At its core, Nano Banana is an AI-powered image generation and editing tool built directly into Google’s Gemini app. While we’ve had AI image generators for a few years, the most crucial question is: what makes this model different?
The answer lies in its remarkable improvements in precision and image fidelity.
Instead of needing complex software like Photoshop, you can simply upload a photo and type commands like “change my shirt to a blue polo,” “remove the person in the background,” or “make the scene look like a vintage photograph.” It’s an interactive, creative dialogue with your images, making sophisticated photo manipulation accessible to everyone.
