Explicit service account authentication for Vertex AI improves governance and onboarding

You can now pass Google OAuth2 service account credentials directly when configuring Vertex AI models. This removes reliance on ambient credentials and gives platform teams precise control over how agents authenticate to Google Cloud, improving security posture and simplifying deployments across environments.
