Drift-Bench (State-Oriented, With Clarification) - Parameter: leaderboard

Drift-Bench (Bao et al., University of Notre Dame, 2026) state-oriented set: 200 AgentBench operating-system and database 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 may call clarification tools (ask for a parameter, disambiguate, propose a solution, confirm a risk, report a blocker), answered by an LLM user simulator playing one of five decision-making personas. Success rate in percent, mean of three trials; higher is better.

Metric: Success rate (%; 200 AgentBench operating-system and database tasks with a parameter fault (a wrong or missing value), clarification tools answered by a persona user simulator, mean of 3 trials). Source: arxiv.org. Saturation forecast: Estimated already saturated. 7 models tracked.
