Hacktoberfest Hack Day Benin City x GDG UNIBEN

Hacktoberfest BENIN Hack Day – LEAF
What if you could walk into a room with an idea and walk out with something you actually built?
LEAF is a one-day Hacktoberfest Hack Day bringing students, developers, creators, and curious builders together at in Benin City for a hands-on experience with open-source technology, open-source AI, open-weight models, GitHub, and modern developer tools.
This isn’t a conference where you sit and watch people build.
You learn. You collaborate. You build. You ship.
Throughout the day, participants will explore new technologies, form teams, tackle real-world challenges, and turn ideas into working prototypes. Projects will be documented, demonstrated, and, where possible, deployed and shared through open-source workflows.
Whether you’re an experienced developer, an AI enthusiast, a student taking your first steps into tech, or simply curious about what you can build in a day — LEAF is your invitation to build something real.

Challenges
Best Use of Gemma 4
It’s time to see how much you can build with a lightweight, open model. Gemma 4 packs multimodal intelligence into an open-weights model that you can access through the Gemini API. So, what can Gemma 4 bring to your project?
- Multimodal Experience: Work with text and images to create an assistant that understands more of what users share.
- Focused AI Tools: Build a focused AI tool for learning, creativity, productivity, or your community.
- Rapid Prototyping: Experiment with an open model while using the Gemini API to move quickly from an idea to a working prototype.
Bring your idea to life… what will you build with Gemma 4 today?
Best Open-Source AI Project
Build an original project that uses open-source or open-weight AI as an important part of how it works. Teams could create an agent skill, build with an open-weight large or small language model, or build or adapt an open-source model harness. These are examples within one challenge, and teams may combine them.
Open-source or open-weight AI must be an important part of the project.
The project must be published in a public GitHub repository and use an open-source license.
An agent skill must comply with the Agent Skill Open Standard.
A model-harness entry must include an original implementation or meaningful changes to an existing open-source harness.
Submissions aren’t open for this event.
