Drift-Bench (Service-Oriented, No Clarification) - Premise: 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 false premise (an assumption that does not hold in the environment). 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 premise fault (a false assumption), no clarification tools, mean of 3 trials). Source: arxiv.org. Saturation forecast: Around 2029. 7 models tracked.
