A technical analysis reveals that context compaction in AI agent sessions accounts for a significant portion of operational costs, estimated at 11.8% of the total bill. This process, which shortens context windows when they become too large, incurs additional expenses because subsequent turns require processing a substantial amount of fresh input. While the compaction itself may be free, the subsequent turns are billed as ordinary assistant turns, making the cost less transparent. The analysis suggests that despite the upfront cost, compaction typically repays its expense within approximately 14 turns, though some sessions experience shorter payback periods. AI
