# Samsung Unveils AI Health Foundation Models for Wearables

> Samsung Research America has shown off two AI foundation models, xMAE and HiMAE, built not on text or images but on the messy biosignals your watch already collects: heart activity, sleep, physical activity and more. xMAE focuses on the relationships between different signals over time, while HiMAE is designed to pick up patterns across multiple time scales in wearable data. The idea is to move wearables beyond fixed thresholds and canned alerts toward models that learn the individual and surface more personalized insights. The detail that matters most for everyday users is that Samsung says both run locally on the device rather than shipping your health data to the cloud, which is a meaningful privacy stance for signals this intimate. This is still research being presented rather than a shipping feature, and foundation models for biosignals are early. But it points at where consumer health tech is heading: the same self-supervised approach that powers language models, retrained on the quiet stream of data from your wrist.
