A journalist interviews K Health's CEO about why the company quietly shut down its consumer symptom checker (which ranked last in independent testing) and what PatientGPT actually is. The CEO dodges the core question while defending K Health's move toward health system partnerships.
- K Health's consumer symptom checker scored 21.5% accuracy in a 2025 systematic review of 40 symptom checkers—dead last. GPT-4 scored 71.3%, and laypeople with no app scored 47-62%.
- K Health discontinued its consumer platform December 31, 2025 with no announcement. When asked if poor performance drove the shutdown, the CEO gave a 6-minute answer that didn't address the question.
- PatientGPT's architecture remains vague: the CEO describes "about a dozen agents" running on a mix of open-source and unnamed "other models," with costs determining which models get swapped in. Three different descriptions exist across seven months.
- K Health's own studies (where K Health funded or co-authored) show 77-85% accuracy, while independent research shows 21.5%—a pattern the journalist notes repeats across the AI health industry.
