Drift-Bench (Service-Oriented, No Clarification) - Parameter: leaderboard
Drift-Bench (Bao et al., University of Notre Dame, 2026) service-oriented set: 150 StableToolBench single-tool API tasks that at least two of three reference models solve with the clean instruction, rewritten so the instruction carries a parameter fault (a wrong or missing value). The agent must act without being able to ask the user. Success rate in percent, mean of three trials; higher is better.
Metric: Success rate (%; 150 StableToolBench G1 API tasks with a parameter fault (a wrong or missing value), no clarification tools, mean of 3 trials). Source: arxiv.org. Saturation forecast: Around December 2027. 7 models tracked.
