Codex extension update left users burning 20% of a weekly token allowance in two hours of ordinary prompts

After a Codex extension update, users reported their weekly limits draining dramatically faster despite identical workloads - roughly 20% of the allowance consumed within two hours of reasonably simple prompts on GPT-5.3 and GPT-5.4 at high reasoning effort, across the Codex App, CLI, and VS Code channels. Affected users stated they had no sub-agents or experimental features enabled, ruling out self-inflicted loops. A Reddit reporter found the same pattern and had used up 90% of a weekly limit in less than a day.

What this means for youIf you pay for an AI coding tool with usage limits, an update may have used up your allowance much faster than normal. At work, teams relying on such tools may hit limits sooner than planned and should check their usage dashboards.
