Nano Banana 2 Lite: 4-second text-to-image generation
Nano Banana 2 Lite is Google DeepMind's fastest and most cost-efficient image generation model, purpose-built for high-volume creative pipelines. Running as gemini-3.1-flash-lite-image, it produces polished visuals in roughly four seconds at a fraction of the cost of earlier models — ideal for rapid prototyping, ad variants, and batch generation.
It's accessible through Google AI Studio, the Gemini API, and the Gemini Enterprise Agent Platform, and is rolling out across Search, the Gemini app, NotebookLM, and Google Photos. Every image carries SynthID watermarking, and the model pairs naturally with Gemini Omni Flash to turn stills into video.
