Google Promotes Nano Banana 2 / Pro Image Models to GA

Google moved Gemini 3.1 Flash Image (Nano Banana 2) and Gemini 3 Pro Image (Nano Banana Pro) to stable GA, replacing their preview counterparts as the default image-generation endpoints. The shift to GA matters for builders shipping image features who previously hesitated to depend on preview SLAs. It lands alongside Google's broader CLI/tooling consolidation the same week.
