Codex Windows app exhausted a weekly usage limit in about 62 hours across many parallel tasks

A ChatGPT Pro user ran more than ten independent Codex tasks across several projects through the Codex Windows desktop application. The weekly usage cycle started on August 2, 2026 at about 12:00 and the entire weekly limit was exhausted by about August 5 at 02:00 — roughly 62 hours later. The usage interface reported approximately 3.17 billion tokens during that period, which the user described as disproportionately high for an individual developer even with many active long-context tasks. One task entered a repeated context-compaction and file-rereading loop: the context became full, Codex compacted it, the task reread files or reconstructed its working state, the context quickly grew again, another compaction occurred, and the cycle repeated without producing proportional progress. The issue remains open.

What this means for youIf you pay for an AI coding assistant with a usage cap, one stuck task can use up your whole allowance within days. At work, check usage alerts and watch long parallel sessions.
