In addition to the examples, Google also has Elo scores from Arena.ai ready to go, showing that users rate Nano Banana 2 Lite outputs almost as highly as the non-Lite versions.
Key facts
- For Nano Banana Pro, the input tokens are only a little more at $2 for 1M, but the output pricing is $12 (eight times higher)
- The API rates are $0.25 for 1M input tokens and $1.50 for 1M output tokens
- The new model is part of the Gemini 3.1 family—it’s technically called Gemini 3.1 Flash Lite Image
- You can play with Nano Banana 2 Lite in Google AI Studio, and it’s live in the API
Summary
There are plenty of AI image-generation models these days, but the ones capable of quality outputs tend to be slow and expensive. The new model is part of the Gemini 3.1 family—it’s technically called Gemini 3.1 Flash Lite Image. You can go from text to an image in about 4 seconds in the default low-thinking mode. For Nano Banana Pro, the input tokens are only a little more at $2 for 1M, but the output pricing is $12 (eight times higher). If you’re tinkering with an AI model to make a single image, it probably makes sense to use the Flash or Pro versions of Nano Banana.
