OpenAI has issued multiple ad-hoc Codex usage resets in recent weeks, with the latest global reset for paid users confirmed on September 26 following a brief service disruption. These resets often coincide with major model launches such as GPT-6 Sol, Luna, and Astra, or address elevated consumption from agentic features, background suggestions, and quality fixes. Engineering lead Tibo Sottiaux frequently announces them on X, alongside banked resets granted during rollouts to compensate users or smooth compute load. The system combines personal rolling five-hour windows with weekly caps that restart on first use after a reset, while historical patterns show median intervals of roughly three to seven days amid ongoing AI capability expansions and competitive pressure from rival coding models. Traders monitor announcements around events like OpenAI DevDay on September 29 for potential catalysts.
