Benchmarks

GenMD Clinical Index

Benchmarks that measure whether frontier models can do the real work of medicine — built from real cases, written and graded by practicing physicians.

Radiology

Reasoning questions built from real radiology reports, where a model must read the findings and apply one step of clinical knowledge.

Built from

GenMD Nexus Data

Verified by clinicians

Nexus_Benchmark

67 tasks

Single-best-answer questions written from de-identified radiology reports and verified by clinicians. Each task passed validity checks (the key holds against the full report, the answer cannot be guessed without the report) and is graded on the model's chosen option.

98 tasks

The full suite: the 67 Nexus_Benchmark tasks plus 31 harder tasks, 98 in total, all verified by clinicians and checked the same way. The harder tasks are the ones the reference model never answered correctly.

Frontier AI

Clinical data, ready for frontier models.

Longitudinal, multimodal clinical data curated for every stage of model development.

Pre-training

Large-scale, longitudinal patient journeys.

Post-training

Physician-annotated tasks and trajectories.

Evaluation

Uncontaminated clinical sets.

Built with health systems, not around them.

Every dataset is sourced through direct partnerships, de-identified with validated methods, and governed by its originating institution. Provenance you can document. Access you can defend.
