PSEBench - Uncertainty Detection: leaderboard
A PSEBench patient safety triage dimension: the binary F1 of escalating irreducibly ambiguous gray-zone events to the Uncertain verdict, in percent; higher is better. PSEBench (2026) builds 5,074 verifiable cases from clause cards of the Minnesota 29 reportable adverse health events, and models may query a simulated information provider before answering.
Metric: Uncertain detection F1 (%, M7): binary F1 of routing gray-zone cases to the Uncertain verdict, over all cases, on the 5,074-case MN29 benchmark (3,455 complete, 1,362 missing-information and 257 uncertain cases built from clause cards of the Minnesota 29 reportable adverse health events), agentic environment where the model may ASK a GPT-5.2 information provider within 10 turns and then answers with a verdict, clause, legal evidence and rationale; higher is better. Source: arxiv.org. Saturation forecast: Around February 2027. 15 models tracked.
