Hey @Abednego,

The model id for Nano Banana is gemini-2.5-flash-image-preview. If you are building on Vertex AI, then check out these resources:

If you are using AI Studio, then you may want to check out these forums: Gemini API - Google AI Developers Forum which cover AI Studio.

Let us know how you go!

You can use the global endpoint, which is supported for this model (Deployments and endpoints | Generative AI on Vertex AI | Google Cloud):

https://aiplatform.googleapis.com/v1/projects/{PROJECT_ID}/locations/global/publishers/google/models/gemini-2.5-flash-image-preview:{METHOD}

Key components:

  • {PROJECT_ID}: Your Google Cloud Project ID.
  • {LOCATION}: Use global for this model.
  • {METHOD}: The API method you want to call. For generative content, this is typically generateContent or streamGenerateContent.

Example using generateContent with the global endpoint:
