Nano Banana 2 Lite from Google is now available on AI Gateway . This Flash-Lite-tier image model is built for fast, low-cost generation. It generates images alongside text in <4s and can edit existing images across multiple turns.

The cost is also lower than previous Nano Banana models. Nano Banana 2 Lite generates 1K images at $0.034 each, about half the cost of Nano Banana 2 and roughly a quarter of the cost of Nano Banana Pro at the same resolution.

This model is multimodal. Use streamText or generateText to generate images alongside text responses.

To use Nano Banana 2 Lite, set model to google/gemini-3.1-flash-lite-image in the AI SDK :

import { generateText } from 'ai' ;

const result = await generateText ( {

model : 'google/gemini-3.1-flash-lite-image' ,

providerOptions : {

google : { responseModalities : [ 'TEXT' , 'IMAGE' ] } ,

} ,

prompt : 'Vercel shipping container boat in 8-bit.' ,

} ) ;
