Google DeepMind has shared the unique origin story behind its viral image model, Nano Banana. The name was conceived at 2:30 a.m. by Naina Raisinghani (Product Manager at Google) to meet a deadline for LMArena, a public platform where users compare AI models through anonymous testing (pairwise comparisons). Raisinghani combined her personal nicknames, "Naina Banana" and "Nano," to create a codename for what was technically known as Gemini 2.5 Flash Image. The model quickly climbed the leaderboards on LMArena, becoming the top-rated tool for image editing globally. It excelled at maintaining a person’s likeness and executing complex, multi-image edits. This success was fueled by "culturally relevant prompts" that went viral across different regions, such as the saree trend in India and figurine trends in Thailand. The team observed that the model's availability to both developers and consumers simultaneously on day one significantly boosted its adoption. Following the viral success of the codename, Google has fully embraced the branding. They updated the interface in AI Studio with yellow buttons and banana emojis. Most notably, the company has officially named its latest successor, Gemini 3 Pro Image, as "Nano Banana Pro." This move highlights a shift toward more playful, community-driven branding within Google’s advanced AI lineup.
