Build with AI 2026: Agentic Hackathon
About Build with AI Hackathon
Build with AI 2026 is here! 

This is a community-led, hands-on hackathon where developers of all levels acquire and apply skills to prototype, build, and deploy applications using the latest Google AI technologies: Gemini 3, Vertex AI, AI Studio, and Antigravity.
Our hackathon is a two-week intensive sprint focused on AI Agents and the ADK (Agent Development Kit). 
Participants are actively engaged in rapid problem-solving, moving from initial ideation to a functional, tangible prototype.

Goal: 
Transform an idea into a working solution using Google’s AI ecosystem to solve real-world challenges.
