Nano Banana 2 Lite
Nano Banana 2 Lite, officially Gemini 3.1 Flash Lite Image, is Google's speed- and cost-focused model for 1K image generation and editing. In VidGen, create from text or edit with up to four reference images, choose from 14 fixed aspect ratios or let the model select the ratio automatically, and optionally use priority processing. It is built for fast visual iteration, while Nano Banana 2 remains the better fit when you need 2K or 4K output, broader reference handling, or Google Search grounding.
