Build with Gemma NYC: On-Device AI for Healthcare is a one-day, in-person hackathon building the next generation of healthcare tools with Google's open Gemma 4 models. Approved and prize-funded by Google's Gemma team, with a $2,000 prize pool distributed via Kaggle.

Healthcare has the hardest privacy constraints in software, and Gemma 4 is built for exactly that: it runs locally, so patient data never has to leave the device. You'll have one day to ship a working prototype and demo it live.

Three tracks:

• Voice for Care: scribes, intake, triage, reminders, and accessible, multilingual patient communication.
• Agentic Care Copilots: agents that automate healthcare admin like prior authorization, referrals, and scheduling.
• On-Device Private Health Tools: fully offline tools where patient data never touches the cloud.

Scope: decision-support tools for documentation, navigation, accessibility, triage, and education. Not diagnosis or treatment. Synthetic or public data only.

Schedule (Saturday, July 25):

• 11:00 AM: Doors, check-in, kickoff

• Gemma Integration — 30 points
  How effectively did the team use Gemma 4? Is Gemma core to the solution rather than an add-on? Judges consider how well the model is applied through prompting, RAG, fine-tuning, function-calling, or on-device deployment.
• Innovation & Impact — 30 points
  Does the project solve a meaningful healthcare problem? Is the approach creative, relevant, and genuinely useful for patients or clinicians? Bonus for solutions that lean into privacy-first, on-device value.
• Functionality — 20 points
  Does the prototype actually work? Is the live demo convincing and reasonably complete for a one-day build?
• Presentation & Writeup — 20 points
  Is the Kaggle Writeup clear and well-documented? Does the demo clearly explain the problem, the solution, and how Gemma 4 was used
