We raise the clinical ceiling of frontier models, with data only physicians can make

Kaelio Health is a clinical data company. Practicing physicians author net-new, uncontaminated cases and grade model trajectories, so labs get faithful evaluation and training signal for medical reasoning.

Why we exist

Today's medical benchmarks are static, contaminated, and increasingly graded by models that barely beat chance. That is a data problem. We solve it at the source: clinical access, consent, and real produce-and-grade work by physicians, not desk labeling of an existing corpus.

How we work with labs

Scope, case count per specialty, action-space coverage, adjudicators per rubric, and inter-rater reliability targets are fixed up front in a pilot spec. We deliver in your formats, with documentation, and start with one free reference case so you can judge fidelity before committing.
