Class VertexAI (1.11.0)

public class VertexAI implements AutoCloseable

This class holds default settings and credentials to make Vertex AI API calls.

Note: The VertexAI instance will start a service client when the first API call is made. Please close the VertexAI instance after making any API calls so that clients get closed as well.


 try (VertexAI vertexAi = new VertexAI("my-project", "us-central1"); ) {
   GenerativeModel model = new GenerativeModel("gemini-pro", vertexAi)
   // Do something with the model.
 }

Constructors

VertexAI()

public VertexAI()

Constructs a VertexAI instance.

Note: SDK infers location from runtime environment first. If there is no location inferred from runtime environment, SDK will default location to us-central1.

SDK will infer projectId from runtime environment and GoogleCredentials.

VertexAI(String projectId, String location)

public VertexAI(String projectId, String location)

Constructs a VertexAI instance.

Parameters
Name	Description
`projectId`	`String` the default project to use when making API calls
`location`	`String` the default location to use when making API calls
