OccuBench (Implicit Faults): leaderboard
Metric: Completion rate (%) over all 382 tasks when the simulator injects implicit faults (truncated or stale data with no error signal; E2, two transient fault events of two calls each); 382 tool-use task instances from 100 professional scenarios, the environment simulated by Gemini-3-Flash-Preview and each trajectory passed or failed by a rubric verifier; thinking mode on, high reasoning effort where configurable; higher is better. Source: arxiv.org. Saturation forecast: Around February 2027. 9 models tracked.
