UserToolBench: leaderboard
UserToolBench (Sun Yat-sen University and Huawei Noah Ark Lab, 2026) tests whether tool-use LLMs make the decisions a specific user would want when the user profile is hidden: the model sees only the interaction history, the current request and the tool schemas, across 10 privacy-sanitized user profiles and 36 tool sets. Exact trajectory accuracy in percent, averaged over single-tool, multi-tool and lack-of-information tasks; higher is better.
Metric: Exact trajectory accuracy (%; mean of the single-tool, multi-tool and lack-of-information task-type accuracies; a trajectory counts when it matches the profile-conditioned reference: the tool name and decision-relevant arguments, the ordered call sequence for multi-tool tasks, or the correct clarify-or-infer decision when information is missing; 799 profile-hidden evaluation instances from long-horizon interaction trajectories of 10 privacy-sanitized user profiles over 36 tool sets; the model sees the interaction history, the current request and the tool schemas but not the profile).
