Agent cost benchmark: the money goes to retrieval, not reasoning — 66% cheaper with memory
Coworker_ai · reddit · 2026-09-04
Coworker benchmarked 114 agent tasks with and without a memory layer in front of Claude, same agent and prompts. The wins landed on Jira/GitHub/Slack lookups (89% cheaper) rather than hard reasoning, with 66% overall savings. The insight: agents re-derive yesterday's query every run, and since nobody splits retrieval spend from reasoning spend, it just shows up as a bigger bill. Full methodology promised in comments.
