A 4-hour AI-powered mini hackathon where you don’t start from scratch — you start with a challenge.
Teams of 3–4 members will receive a random open-source repository, basic project, or product idea. Your mission: use AI and your engineering skills to transform it into a better, working solution.
Use open-source AI tools & open-weight models
Build, improve, and experiment
Ship a working solution in 6 hours
Demo your final creation to the judges
Projects will be judged on innovation, technical execution, AI usage, problem-solving, and the final working demo.
One repo. One challenge. Eight hours. What can your team build?

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?
