Join a groundbreaking collaboration between Mila, Bell, Buzz HPC and Kids Help Phone on Canada's most comprehensive AI ecosystem, Bell AI Fabric. From March 16 to 23, 2026, we're uniting top AI minds with deep expertise in youth mental health to build innovative AI solutions that empower young Canadians to interact safely with conversational AI tools.
While conversational AI offers immense promise, it also carries risks, potentially amplifying psychological distress. This hackathon challenges you to use your voice, skills and lived experience to fortify the future of AI safety. We’re inviting Canada's brightest minds in guardrail training, prompt engineering and synthetic data to stress test and develop systems and guidelines to strengthen AI support for youth mental wellness.
- Your mission: Identify vulnerabilities and engineer robust defences—build the armour that keeps our youth safe—by diving deep into three critical areas: Adversarial stress-testing, logic hardening, and synthetic data augmentation.
- Expert evaluation: Your solutions will be judged by a distinguished panel of AI safety experts, clinical psychologists and UX professionals. They'll assess your work based on safety, user experience and data quality.
- Win big: Do your part to help save lives, compete for a share of CAD 10,000 in monetary prizes and get the inside track to an exclusive internship with the Mila AI Safety Studio.
