Class VertexAI (0.3.0)

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.
 }
