AutoMedBench - Lesion Detection: leaderboard

The lesion detection track of AutoMedBench (2026), which asks an LLM agent to complete end-to-end medical-AI research tasks built from public challenge datasets: four lesion detection tasks. Each run is scored 0 to 100 as the mean of the held-out result (mAP at IoU 0.5) and a five-stage workflow score (plan, setup, validate, inference, submit), averaged over the Lite and Standard tiers. Higher is better.

Metric: Overall run score (0-100) on the lesion detection track (4 detection tasks): the mean of the held-out task score (mAP at IoU 0.5, scaled to 0-100) and the workflow agentic score (Plan, Setup, Validate, Inference and Submit stages weighted 25/15/35/15/10, LLM judge for the first three); each model is the single agent of the benchmark harness (shared code-execution interface, system prompt, tool schema and default decoding; no vendor agent framework), runs averaged over the Lite and Standard tiers; higher is better. Source: arxiv.org. Saturation forecast: Around February 2027. 6 models tracked.
