Cloud-OpsBench (TrainTicket): leaderboard
Metric: Joint RCA accuracy (%): share of episodes whose predicted faulty component and fault type both match the label, on Cloud-OpsBench's TrainTicket fault cases (part of 754 runtime-verified cases over 57 fault types); the model drives the authors' ReAct agent (Pydantic-validated tools, temperature 0, at most 20 steps, extended thinking disabled) over snapshot-replayed Kubernetes diagnostic tools, from a user query describing the observed failure; higher is better. Source: arxiv.org. Saturation forecast: Estimated already saturated. 10 models tracked.
