AgentRewardBench (Accessibility Tree): leaderboard
AgentRewardBench (McGill NLP, 2025) tests whether an LLM judge can tell if a web agent succeeded, using 1,302 expert-annotated trajectories from AssistantBench, VisualWebArena, WebArena, WorkArena and WorkArena++. This board scores the authors' simplified judge given the final accessibility tree of each trajectory, as precision (%): the share of trajectories the judge calls successful that the experts also marked successful; higher is better.
