Google Vertex AI Agent Builder

Vertex AI Agent Builder was Google's suite for developing production-ready AI agents using Gemini and other models, enterprise data, tools and APIs. In 2026, Google transitioned Vertex AI into Gemini Enterprise Agent Platform, where Agent Builder capabilities continue under the new platform. Developers can build agents with the Agent Development Kit (ADK), deploy them using managed agent runtime services, connect enterprise data and tools, evaluate agent performance, and apply governance/security controls. It is designed primarily for developers and enterprises rather than casual users. Country availability: Google Cloud is broadly available internationally. India is supported, although individual Agent Platform services and regions can have specific regional availability. Google Cloud lists Mumbai (asia-south1) among its supported AI/agent-related regions, while specific Agent Runtime regions vary by service.
