Vertex AI Agent Builder overview

Vertex AI Agent Builder is a suite of features for building and deploying AI agents. It consists of the following components:

• Agent Gardenis a library where you can find and explore sample agents and tools that are designed to accelerate your development.

  Go to Agent Garden

• Agent Development Kit (ADK) is an open-source framework that simplifies the process of building sophisticated multi-agent systems while maintaining precise control over agent behavior.

• Vertex AI Agent Engine is a set of services that enables developers to deploy, manage, and scale AI agents in production. Vertex AI Agent Engine offers services such as a fully-managed runtime, evaluation, Sessions, and Memory Bank.

• Agent Toolsare tools that you can equip your ADK agent to use, including:

  • Built-in tools such as Grounding with Google Search , Vertex AI Search , and Code Execution

  • RAG Engine for retrieval-augmented generation (RAG)
