# Nano Banana 2 Lite

> Lightweight image generation with wide aspect ratio support and 1K output

Nano Banana 2 Lite is the lightweight variant in the Nano Banana family. Compared to [Nano Banana 2](/models/image/google/nano-banana-2) and [Nano Banana Pro](/models/image/google/nano-banana-pro), it supports a wider set of aspect ratios (including `auto` and ultra-wide/tall formats) but is limited to **1K** output resolution.
