GroundCheck: clinical answers that cite their sources or refuse
An open-source clinical retrieval system that cites every claim and stops when its trusted sources cannot support an answer.
Field notes
The pipeline applies eleven ordered checks, including retrieval, source coverage, grounding, and dosage protection, while saving a trace for answered and refused requests. The homepage reports testing on 2,008 questions, including 1,004 designated must-refuse cases, and shows a refusal completing before model generation when “zalortin” is absent from trusted sources. Its example corpus links MedQuAD and DailyMed, and the project states that the 1,880-document evaluation set contains no real patient data.
