Coalition for Health AI (CHAI), a nonprofit founded by clinicians to advance responsible health artificial intelligence (AI), announced new efforts to enable health systems, payers, and health tech companies to respond to frontier model threats, defending against potential attacks and harnessing frontier models for defense.
Frontier model technology refers to the most advanced, large-scale artificial intelligence systems available at any given time. They sit at the cutting edge of capability, using massive computing power, broad multimodal designs, and deep reasoning skills to handle many different tasks rather than just one narrow job.
The Health AI Cybersecurity Work Group, led by a leadership council of health system, payer, and industry experts, will give healthcare organizations the sector’s first practical, peer-developed guidance on frontier model cyber risk and readiness through playbooks released at the end of 2026. The effort will be steered by leadership council members, who will guide the nearly 100-member work group.
“Health systems have always faced cybersecurity challenges, but today’s advancements in AI fundamentally change our threat level. With these unprecedented capabilities, it’s key that industry leaders work together to develop a real toolkit for hospitals, health systems and beyond,” John Flores, CISO, University of Texas Medical Branch, said via a statement. “I applaud CHAI for moving quickly to gather this work group — as hospitals of all sizes are seeking resources to combat risks associated with new complex technologies.”
