Open to BBD students only. A valid college ID card is required for entry.
🚀 What to Expect
• Hands-on building time, solo or in teams, with help from organizers and mentors

🏆 Prize Challenge
There are two challenges, and the winning team in each receives swag, subject to availability.
Best Open-Source AI Project: Projects must use open-source or open-weight AI as an important part of how they work, be published in a public GitHub repo, and carry an open-source license. Teams can build something new or meaningfully improve an existing open-source project.
Best Use of Gemma 4: Build with Gemma 4, Google’s open-weights model, accessed through the Gemini API. Work with text and images to create an assistant, a focused AI tool, or a quick prototype.
Full rules are on the Challenges tab. Submissions close before demos begin.
🎒 What to Bring
Your laptop and charger, a GitHub account, your college ID card, and a project idea.
Supported by Major League Hacking (MLH), DEV, and DigitalOcean.
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.
