What is Google ADK (Agent Development Kit)?

Google Agent Development Kit (ADK) is a comprehensive framework for building production-ready AI agents using Google Gemini models. It provides tools for agent orchestration, multi-agent systems, state management, and deployment patterns.

Is Google ADK training free?

Yes! All 34 tutorials, mental models, code examples, and production deployment guides are completely free. You can access everything without any registration or payment.

What will I learn from Google ADK Training Hub?

You will learn to build production AI agents from scratch, including multi-agent systems, agent orchestration patterns, Google Gemini integration, deployment on Cloud Run and Vertex AI, UI integration (React, Next.js, Streamlit), MCP tools, A2A protocol, and comprehensive testing strategies.

Do I need prior AI experience to start?

No prior AI experience required! The training starts from first principles with a "Hello World" agent and progressively covers advanced topics. Basic Python or JavaScript knowledge is helpful but not mandatory.

How long does it take to complete the training?

The complete training comprises 34 tutorials totaling approximately 34 hours of hands-on learning. You can go at your own pace - complete it in a week of intensive study or spread it over several weeks.

Can I deploy agents to production after this training?

Absolutely! The training includes comprehensive production deployment guides for Google Cloud Run, Vertex AI Agent Engine, and GKE. You will learn testing, monitoring, and best practices for production-grade AI agents.
