Join Android Club VITC for a full-day Hacktoberfest 2026 Hack Day — a mini-hackathon built around open source, AI, experimentation, and shipping.
This isn't a workshop or a lecture. You come with your team, find a problem worth tackling, and spend the day building. Explore open-source AI, experiment with open-weight models, hack on existing projects, and turn your ideas into something you can actually demo.
Best Use of Gemma 4
Build with Google's lightweight, open model Gemma 4 and explore what you can create with multimodal AI. Projects can use text and images to build assistants, focused AI tools, or creative, learning, productivity, and community-focused applications. You can experiment with Gemma 4 through the Gemini API and turn an idea into a working prototype.
Best Open-Source AI Project
Build an original project where open-source or open-weight AI is an important part of how it works. You can create an agent skill, build with an open-weight LLM or SLM, or build/adapt an open-source model harness. Your project must be published in a public GitHub repository under an open-source license.
Whether you're a seasoned hacker or this is your first hackathon, bring your ideas, your team, and your laptop. There are no lectures to sit through and no workshops to follow — the day is yours to build.
Come with a problem.
Find an idea.
Build it. Break it. Improve it.
Ship it.
Build. Ship. Contribute.
