Abstract

fetched live from OpenAlex

Generative artificial intelligence (AI) shows remarkable abilities to provide accurate and relevant responses to queries in specialist domains such as clinical medicine. The advancement in generative AI tools has led to excitement and concern regarding their potential to augment health care by improving the efficiency and performance of clinicians.1 Although initial interest was generated through contrived tasks such as answering examination questions, several studies have evaluated generative AI in the context of more realistic clinical applications.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
