Google Releases Nano Banana 2 Lite (Gemini 3.1 Flash Lite Image) as Fastest and Cheapest Image Model
English summary
Google has introduced Nano Banana 2 Lite, officially named Gemini 3.1 Flash Lite Image (API identifier gemini-3.1-flash-lite-image), marketed as the fastest and most affordable model in the Gemini image generation family. The model is designed for high-velocity, large-scale use. In a quick test using Google AI Studio, Simon Willison generated a "Where's Waldo"-style image featuring a raccoon with a ham radio, and found the result more satisfactory than earlier Nano Banana models tested in April. However, the generated text misspelled "Forest Festival" twice.
