Nano Banana 2 followed Google's original Nano Banana and Nano Banana Pro image models. Launched in February 2026 as Gemini 3.1 Flash Image, it aimed to bring more of the Pro model's creative capabilities into the faster Flash experience.
The release focused on quicker generation and editing alongside better control over subjects, text and instructions. Google also connected image creation to web information and expanded access across its products. The design goal was to make repeated visual iteration more practical without requiring users to choose only between speed and control.
