Specify a location to run the service and access a model

When initializing the Vertex AI service, you can optionally specify a location in which to run the service and access a model. If you don't specify a location, the default is us-central1. See the list of available locations later on this page.

Note that these samples show accessing a Gemini model, but you can also specify location when accessing an Imagen 3 model.

import FirebaseVertexAI

// Initialize the Vertex AI service
// Optionally specify a location in which to run the service and access the model
let vertex = VertexAI.vertexAI(location: "LOCATION")

// Initialize the generative model with a model that supports your use case
let model = vertex.generativeModel(modelName: "MODEL_NAME")

Available locations

Google Cloud uses regions to define regional APIs. Google Cloud only stores customer data in the region that you specify for all generally-available features of Generative AI on Vertex AI.

Generative AI on Vertex AI is available in the following regions. Some models and/or specific versions may not be available in all locations (for detailed location availability, see the Google Cloud documentation).
