Nano Banana is the image generation and photo editing model built into Google's AI assistant app, with the current version called Nano Banana 2. Users pick the create-images option from its menu of options, choose Fast, Thinking or Pro, then type a prompt or upload a picture to change. It can swap a background, replace an object, or add an element while keeping the details the user likes, and it can borrow textures, colors and materials from a reference photo.
Social media creators, small business owners and marketers use it to produce visuals without design software, and hobbyists enjoy it for surreal scenes and quick experiments. Designers can draft concepts, test camera angles, lighting and mood, and resize one idea into several aspect ratios. Students and teachers can build illustrated material, while multilingual teams benefit from text rendering that can also translate wording inside an image and fit it into the layout.
Practical examples include logos, invitations, posters and comics where the message appears as readable text in the picture, product mockups in different settings, and mood variations of a single scene shifted from day to night or from playful to mysterious. Photo editing covers changing a backdrop or removing a distraction through a plain-language request, and a follow-up message adjusts the result when the first attempt misses. Every generated image receives a visible watermark and an invisible SynthID watermark so viewers can tell it was made by AI. Users on Google AI Pro, Plus and Ultra can regenerate an image with the Pro model.
