Wang and colleagues tested whether long-running language-model agents need to retain all of their earlier reasoning.

The authors developed Interaction Aware Compression for Long Horizon Reasoning (ICLR), a training-free online method that uses entropy estimates from a frozen proxy model to rank reasoning blocks for removal.
