Introduction
In a groundbreaking move at Google I/O 2025, Google unveiled its Agent Development Kits (ADKs) for Python and Java — a major step in simplifying how developers build, test, and scale intelligent AI agents. Whether you’re a machine learning engineer or a full-stack developer, the Google Agent Development Kit offers a modular, production-ready solution for real-world automation and reasoning tasks.
What is the Google Agent Development Kit?
The Google Agent Development Kit (ADK) is an open-source toolkit that helps developers create AI agents capable of performing tasks autonomously. It provides:
- A code-first development model
- Tools for building modular multi-agent systems
- Integration with Google’s Vertex AI Agent Builder for deployment
Why It Matters for Developers
With AI workflows growing more complex, traditional monolithic models fall short. Google’s ADKs introduce:
- Python ADK (v1.0.0): Production-ready, ideal for rapid prototyping and AI research
- Java ADK (v0.1.0): Early access, great for backend-focused enterprise systems
These toolkits enable structured, testable, and composable agents that can be versioned and scaled.
Key Features of Google’s ADK

Code-First Agent Logic
Write clean agent behavior directly in Python or Java. No black boxes.
Multi-Agent Composition
Build intelligent hierarchies of agents, ideal for complex workflows like data analysis, automation, or customer service.
Tool Integration
Plug in APIs, webhooks, and external tools effortlessly for maximum flexibility.
Cloud-Ready Deployment
Deploy agents using Google Cloud’s Vertex AI, with automatic scaling and monitoring support.
How to Get Started
For Python:
pip install google-adk
For Java (Maven):
<dependency>
<groupId>com.google.adk</groupId>
<artifactId>google-adk</artifactId>
<version>0.1.0</version>
</dependency>
You can begin building agents in minutes. The documentation includes samples, templates, and workflows to jumpstart development.
Best Use Cases for the Google ADK
- Task Automation Agents – Automate IT, DevOps, or support workflows
- Data Analysis Bots – Agents that process and summarize large datasets
- Productivity Agents – AI copilots for email, scheduling, and research
- Multi-Step Assistants – Design agents that collaborate and plan using sub-agents
