Google explains the differences between its three Nano Banana image generation models

Google has published an official guide for its Nano Banana image generation models, breaking down the differences between all three and explaining when to use each one.

Google has laid out the capabilities of its Nano Banana models in a detailed guide, with a focus on the recently released Nano Banana 2, which is based on Gemini 3.1 Flash Image. With three models now in the family, the guide helps developers and creatives figure out which one fits their use case.

NB2 handles most use cases at a fraction of Pro's cost

Google says Nano Banana 2 delivers about 95 percent of the capabilities of the pricier Nano Banana Pro, but at a significantly lower price point. That makes NB2 the recommended default for most new projects.
