Google announced the launch of Nano Banana 2 Lite, an artificial intelligence image generation model optimized for speed and lower costs, targeting businesses and developers that need to generate large volumes of images for commercial applications. The model, also called Gemini 3.1 Flash-Lite Image, is Google’s fastest and most cost-efficient image generation model, and can generate a 1K-resolution image in under four seconds at a cost of just $0.034 per 1K image. Now available through Google AI Studio, the Gemini API, and the Gemini Enterprise Agent Platform, the model is built on the Gemini 3.1 Flash-Lite architecture and is intended for high-volume image production in advertising platforms, e-commerce, and rapid development tools. Enhancements over its predecessor include improved general knowledge, better scene and contextual layout generation, greater consistency of characters and objects across a sequence of images, and improved multilingual text rendering. Nano Banana 2 Lite is limited to generating images at 1K resolution, unlike Nano Banana 2 and Nano Banana Pro which support up to 4K, but Google said this limitation contributes to greater efficiency.
