Models
Healthcare-specific and healthcare-adapted AI models.
HAIHQ / Open research
HAIHQ is a nonprofit, open-source research organization building models, datasets, benchmarks, and tooling for Health AI.
We research technical problems, build systems to investigate them, evaluate what works, and make the resulting work open.

Healthcare-specific and healthcare-adapted AI models.
Open healthcare datasets for training, testing, and studying Health AI systems.
Evaluation systems for measuring capability, reliability, safety, robustness and real-world behavior.
Open infrastructure for building, testing and operating Health AI systems.
Current work
Reactive FHIR infrastructure for applications and AI agents.
ReFHIR explores what FHIR should look like when software is continuously operating over changing healthcare state.
Instead of manually combining queries, subscriptions, refetching and state reconciliation, applications and AI systems can subscribe directly to live FHIR query results.
We start with a technical question.
We build the system needed to investigate it.
We measure what happens.
Then we release the useful parts openly.
HAIHQ works with researchers, engineers, clinicians, healthcare organizations, universities and supporters interested in advancing open Health AI.
