Why Pay for Long Reasoning When Rewrite Do Trick? Causal Effects of Reasoning History Compaction on Future Generation and Agent Cost
Rewriting earlier reasoning into compact records usually shortened models’ subsequent reasoning, without retraining.
The study compressed prior reasoning before revealing pending tool results, then compared continuations against those using the original histories. A coding case study also found less repeated verification after a shared candidate solution. In software-agent deployments, compaction could lower total spending, but task quality and total time—including rewriting—depended on the target model and compressor.
