Reconstruction (Research Idea Recovery) - Physics: leaderboard
The 138 physics papers of Reconstruction (AI-Professor Project, 2026), where a model sees only the pre-publication bibliography of a paper and proposes five hypotheses judged against its withheld idea. Match rate in percent, averaged over leave-one-out peer judges; higher is better.
Metric: Match rate (%; the 138 physics seed papers; share of a model's five hypotheses, proposed in one call from a published paper's pre-publication bibliography only (titles and abstracts under anonymous IDs, the paper itself and later literature withheld), that an LLM judge matches to the held-out paper's idea; mean over the six other evaluated models as leave-one-out judges). Source: arxiv.org. Saturation forecast: Around 2029. 7 models tracked.
