The mysterious post was a fun reference to a big new change: the “Gemini 2.5 Flash Image” upgrade to Google’s Gemini AI. Internally, this new model is called “Nano Banana,” and it is meant to give the Gemini app advanced tools for creating and editing images.
Google DeepMind’s official X account tweeted about a “bananas upgrade” and linked to a blog post called “Nano Banana!” Gemini’s image editing tools have got a big boost. The blog says that the new function lets users alter pictures with a lot of power using simple text prompts. They can even put together several pictures into a new, coherent scenario.
People were both confused and excited by Pichai’s remark. At first, a lot of people wondered if the account had been hacked or asked for “context.” The AI chatbot Grok, which is owned by Elon Musk’s xAI, correctly predicted what the message meant. It said that it was probably a teaser for Google’s upcoming AI tool.
The official Google site says that the “Nano Banana” tool is meant for “precise image editing and generation.” It lets users make specific modifications, such blurring backgrounds, getting rid of things, or even changing a character’s stance, all while keeping the image’s quality and consistency. The Gemini app makes the tool available to people all over the world, whether they pay for it or not.
The episode shows how more and more tech companies are utilizing fun and unusual ways to promote excitement for new products, such using social media and AI chatbots to talk to people all across the world.
