Data and RL environments for biological and health AI
We are building Osseus, a data platform providing ready-to-use and custom medical and biological datasets, as well as RL training environments for AI labs focused on health and biology. We also work with hospitals and clinics to supply EHRs and deploy AI models directly within clinical workflows. Labs use us to accelerate research and model deployment; healthcare providers use our platform to access and integrate AI.
n/a
