Tibo, who leads OpenAI's Codex team, announced on X over the weekend that the company had reset weekly usage quotas for all paying Codex and ChatGPT Workspace subscribers. Codex is OpenAI's AI coding agent, which allots token-based quotas to paid users on a weekly cycle.

The reset followed weeks of complaints that quotas were running out faster than expected. After reviewing thousands of reports, the Codex team traced the problem to eight separate bugs and worked overnight to patch them. Tibo said the fixes free between 10 and 50 percent more usable quota, depending on how a user works with Codex, without changing the allowance itself.

The patched issues include a context-compaction flaw that kept old image data in memory after compression, adding roughly 10 percent extra token use for heavy image users. A background-memory bug caused tasks to ignore stop hooks; in one case a single thread checked whether it could stop more than 15,000 times. Goal-management tasks sometimes failed to shut down after completing, or retried broken tool calls, consuming 15 to 70 percent of a user's weekly quota in the worst cases. Custom scheduled automations ran more often than configured. Smaller models such as Luna occasionally launched more powerful subagents without user approval, and the main model sometimes ran subagents in /fast mode outside of that setting.

A separate bug in the Computer History feature repeatedly re-summarized overlapping activity, which alone consumed up to one-fifth of some users' weekly quota. Rolling task summaries triggered hidden background requests adding about 1 percent overhead and have now been disabled entirely. In the Model Context Protocol (MCP) integration, some tool results were encoded twice and truncated instructions were re-fetched unnecessarily.

Tibo said the team added architectural safeguards, including automatic alerts when similar waste patterns recur, and plans to add a usage breakdown so users can see where their tokens go. Some users welcomed the fixes but criticized OpenAI for letting a single bug like Computer History waste a fifth of quota, and others said the reset window was too short for everyone to benefit.
