Hacktoberfest Hack Day Silver Spring x AI Collective
About
Hack for Humanity × Hacktoberfest 2026 — Silver Spring
Join AI Collective Maryland for a one-day hackathon where you’ll build open-source AI tools for social good. Bring an idea or join a team on the spot, build with open-weight models and open-source AI tooling, and demo what you made by the end of the day.
📍 Silver Spring, MD
Who it’s for: Developers, designers, students, and anyone curious about building with AI. All skill levels welcome — you’ll find teammates and help in the room.
Not sure what to build? Write your first open-source skills.md, build an open-source agent, fine-tune an open-weight model, or pick a problem in your community and point AI at it.
The rules:
- Build with an open-weight model or open-source AI tooling
- Ship your project to a public GitHub repo
- Solve a real problem for real people
What to bring: A charged laptop with your dev environment set up and API keys ready, so you can start building right away.
Lunch, Hacktoberfest t-shirts, stickers, and prizes provided.
Hosted by the AI Collective Maryland chapter, co-hosted by Studio Rehoboth, as part of Hacktoberfest 2026 powered by MLH, DEV, and DigitalOcean.

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?
