-----Due to overwhelming demand, some of you may be on the waitlist for this event. We are very sorry about this situation due to space limitations.

If you are on the waitlist for this event, you can subscribe to our calendar for future hackathons with this link-----Whether you're a designer, marketer, founder, student, or engineer -- if you're curious about what you can build with AI, this hackathon is your starting point. No technical background needed.

AI Builders is partnering with Google Japan for Gemini AI Hackathon -- a hands-on, full-day hackathon where you'll go from idea to working prototype using Google's latest AI tools, fresh from Google I/O 2026.

What You'll Build

  • Go from zero to a working AI project in one day -- an app, an agent, a multimodal tool, a workflow, anything you can imagine

  • Attend a beginner-friendly workshop that walks you through everything before hacking begins

  • Form teams (up to 6) or go solo -- your call

  • Demo your project live and compete for Google Cloud credit prizes

  • Connect with builders, creators, and founders

Your AI Stack (Straight from Google I/O 2026)

You'll build with the newest tools Google just shipped at I/O 2026:

  • Gemini 3.5 Flash -- Google's fastest frontier model, purpose-built for agentic workflows and coding. 4x faster than other frontier models while matching them on intelligence. Ideal for building AI agents that reason, use tools, and execute multi-step tasks.

  • Managed Agents (Gemini API) -- Spin up a fully provisioned agent with a single API call. Your agent gets its own isolated Linux environment to reason, use tools, and execute code -- no infrastructure setup needed.

  • Google AI Studio -- Prototype and build full-stack apps directly in-browser. New at I/O: build native Android apps with just a prompt, publish directly to Google Play, and integrate with Google Workspace APIs.

  • Antigravity 2.0 -- Google's agent-first development platform. Orchestrate multiple agents in parallel, create custom agent behaviors with the SDK, and ship production-ready apps.

Your project must integrate Google Cloud products. This is your chance to go hands-on with the tools powering AI teams worldwide -- many of them just days old.

The workshop covers everything you need to get started. No prior experience required.

Agenda

  • 9:30 AM: Check-in

  • 10:00 AM: Opening from AI Builders and Google Japan

  • 10:30 AM: Workshop -- Hands-on walkthrough of Gemini 3.5 Flash, Managed Agents, AI Studio, and Antigravity

  • 11:30 AM: Team formation + Hacking begins

  • 12:30 PM: Lunch

  • 4:30 PM: Hacking ends / Live demos (2 min per team)

Prizes

Winning teams share Google Cloud credits as prizes. All participants receive credits to build with during the hackathon.

Judging Criteria

  • Use of Google Cloud: Your project must use Google Cloud products (Gemini API, AI Studio, Antigravity, Vertex AI, etc.). Missing integration disqualifies your team from prizes.

  • Innovation: How creative and original is your approach? Bonus points for using the latest I/O 2026 capabilities -- Managed Agents, multimodal generation.

  • Completeness: Does it work? Is it demo-ready?

Who Should Join

Everyone. Whether you're a developer, designer, business builder, student, or just AI-curious -- this hackathon is built for you. The workshop at the start gets you up to speed on Google's newest tools, and you'll have mentors and teammates to support you throughout the day.

No coding experience? No problem. With AI Studio's prompt-to-app prototyping and Antigravity's agent-first workflows, some of the best projects come from people who bring fresh perspectives from outside tech.

Team formation happens after the workshop. Work solo or find teammates on the day.
