Paper questions LLM-agent leaderboard validity

A new paper questions the validity of LLM-agent leaderboards, arguing that direct comparisons of ranked agents can be misleading. The authors highlight that differences in task mixtures, data sources, release details, and cost rules can significantly impact an agent's score. They propose an estimand-aware procedure to more accurately assess pairwise superiority, emphasizing the need to consider uncertainty and practical margins when interpreting rank differences, especially on benchmarks like SWE-bench and AgentRewardBench.
