Google has officially launched Nano Banana 2, a faster version of Nano Banana Pro, promising high-fidelity image generation at lightning-fast speeds. By integrating Gemini 3.1 Flash Image architecture, this update brings professional-grade features like 4K resolution and real-time search grounding to the mainstream Gemini app.
Google has enabled users to upload images into the Gemini app and ask whether they were generated by Google AI. The feature relies on SynthID, Google’s invisible watermarking system.
