CEOs and heads of tech companies posting on Twitter is nothing new, but a recent post shared by Google CEO Sundar Pichai left the internet perplexed and confused when he posted three banana emojis on Twitter. The tweet quickly took over the internet and left people speculating about it; the general belief was that it could be a post introducing a new AI tool from Google.
When a user asked Google’s AI platform, Grok, they got this reply: “Sundar Pichai’s [banana emojis] possibly point to Google’s alleged ‘Nano Banana’ AI tool for precise image editing and generation.”
The alleged ‘Nano Banana’ AI feature is expected to be an image editing tool that can offer extraordinary inventiveness and ingenuity, and the AI visuals will be far more precise and accurate.
On Tuesday, Google DeepMind posted, “Image generation with Gemini gets a new and cutting-edge image generation and editing model. From photorealistic masterpieces to mind-bending fantasy worlds, you can now build, edit, and refine scenes with a new level of logic, control, and creativity.”
What is Nano Banana?
This is the new name making a splash in the generative image space – Nano Banana, a tool that many consider to be Google’s quiet experiment in the next generation of visual editing. Its speed and accuracy set it apart: the edit is usually done in just a second or two, while maintaining the consistency of facial details, styles, and objects that most tools struggle with.
With Nano Banana, you can start from scratch or upload an existing photo, type in the changes you want, and watch the model re-render the image almost instantly. It handles background changes, object additions, and fine adjustments with very little effort, without the need for masks or complex layer work.
One of its big advantages is consistency—the look, lighting, and pose of characters remain the same across multiple edits, making it particularly powerful for repetitive tasks.
However, its reach is still limited. So far, Nano Banana has appeared on platforms like nanobanana.ai, Flux AI, Bylo.ai, Dzine, and more recently in LMArena’s “Battle Mode,” where it competes head-on against rival AI models. Testers who have tried it out say the tool excels at photorealism, character restoration, scene reconstruction, and handling multiple edits at once.
