Peer‑Probing lets LLMs Reveal Each Other’s Gaps, Replacing Stale Benchmarks
LivingArena pits LLMs against each other: each model generates questions designed to stump its rivals, with a judge panel validating answers. The resulting Elo rankings expose knowledge gaps that static benchmarks miss and stay resistant to data contamination, while correlating only weakly with human preference scores—offering a cheap, continuous evaluation method.
