Introduction
Google Cloud has launched Advent of Agents 2025, an ambitious 25-day educational initiative designed to help developers build production-ready AI agents using Google Cloud's comprehensive agent development platform. This program combines the power of Gemini 3, the Agent Development Kit (ADK), and Agent Engine to provide developers with a complete toolkit for creating sophisticated AI agents without extensive coding knowledge.
The initiative represents Google Cloud's commitment to democratizing AI agent development and making advanced artificial intelligence capabilities accessible to developers of all skill levels. With daily content releases throughout December, Advent of Agents 2025 offers a structured learning path from basic agent creation to production deployment.
