Nano Banana (Gemini 2.5 Flash Image) is Google's first context-aware image generation model, built on the Gemini 2.5 Flash architecture. Unlike standalone image generators, it combines language understanding with visual generation, enabling conversational image creation, iterative edits through multi-turn dialogue, and contextually grounded outputs. It represents Google's entry into unified text-and-image generation within the Gemini model family.
