Gemini image (Nano Banana): pricing, free tier and licence
Can I sell what it makes? Free tier: commercial use allowed. Paid: commercial use allowed. Full answer with sources
Imagen is shut down in the Gemini API; Nano Banana models replace it. The API is for users 18+ and can't be used in apps directed at, or likely to be used by, under-18s, which matters if your game generates images at runtime. Google Cloud's generative AI indemnity covers Gemini and Imagen on its Agent Platform (formerly Vertex AI) API, not the Gemini Developer API or AI Studio.
