Nano Banana (officially Gemini 2.5 Flash Image) and Nano Banana Pro (officially Gemini 3 Pro Image) are image generation and editing models powered by generative artificial intelligence and developed by Google DeepMind, a subsidiary of Google. A text-to-image variant of the Gemini family of large language models, they were launched in August 2025 and November 2025 respectively as features within the Gemini chatbot and other Google products. "Nano Banana" was the codename used for the model while it was undergoing secret public testing on LMArena. Upon release, Nano Banana became a viral Internet sensation on social media, particularly for its photorealistic "3D figurine" images.
