1M Context Windows Are a Token Trap, Analysis of 2,451 Sessions Shows
_rchaves_ · x · 2026-08-03
Based on an analysis of 2,451 AI agent sessions, the author argues that pushing for massive context windows (like 1 million tokens) might be a trap set by major AI labs to inflate token usage.
The data reveals that every 2x increase in context size results in a 6x spike in token costs, even with caching enabled. Crucially, there is no evidence that earlier tokens are actually needed or utilized in later stages of the work.
The author recommends compacting context at around 450k tokens in agent workflows to maintain performance while keeping costs strictly under control.
