Building Agents Easy with Google

a year ago

Google introduced the Agent Development Kit (ADK) at Google Cloud NEXT 2025, an open-source framework for developing multi-agent systems.
ADK simplifies end-to-end development of agents and multi-agent systems, offering flexibility and control for production-ready applications.
ADK is used in Google products like Agentspace and Google Customer Engagement Suite (CES), now open-sourced for broader developer use.
ADK supports the entire agent development lifecycle, including sequential, parallel, and loop operations, and dynamic routing for adaptive behavior.
Developers can define agent logic, tools, and information processing in Python, with ADK managing state, tool calls, and LLM interactions.
ADK offers multiple interaction methods: CLI, Web UI, API Server, and API (Python), with consistent core logic across all.
ADK excels in multi-agent systems, enabling hierarchical structures and intelligent routing for collaborative agent teams.
Example provided: a WeatherAgent delegating greetings to a GreetingAgent, showcasing ADK's delegation and tool use capabilities.
ADK includes integrated evaluation tools for testing agent behavior and supports deployment to container runtimes or Vertex AI Agent Engine.
ADK is optimized for Google Cloud, integrating with Gemini models, Vertex AI, and over 100 pre-built connectors for enterprise systems.
ADK provides a comprehensive solution for building, evaluating, and deploying intelligent, scalable multi-agent applications.
