Claims
the best-performing tested agent, Claude 3.5 Sonnet (New) with open-source scaffolding, achieves an average replication score of 21.0%.
That the author-co-developed rubrics and the LLM judge together provide a reliable, unbiased measure of successful replication that generalizes beyond the 20 selected papers.
PaperBench is a new benchmark showing frontier AI agents replicate only 21% of tasks needed to reproduce state-of-the-art AI papers, below human expert performance.
