What AI model powers Nano Banana — is it GPT, Gemini, or something else?
Nano Banana (both version 2 and Pro) is powered by Google Gemini, not GPT or any OpenAI technology. This gives it a distinct visual style that excels at photorealistic portraits, detailed product photography, and artistic content. It is not based on Stable Diffusion either — it is Google's hosted model, which PicX Studio runs for you through Google's API. If you want OpenAI's model, GPT Image 2 is available on PicX Studio too.
