### AI overview

The article explains why repeated evaluation on held-out benchmarks can cause overfitting, then frames the apparent contradiction in machine learning research, where benchmark-driven iteration is widespread. It also summarizes research suggesting that compressible models limit memorization.

### Source excerpt

New research indicates that AI agents learn compressible models of data, which don't have enough space to enable memorization.
