OpenAI’s Codex weekly usage limits, which cap paid subscribers’ access to its coding large language models, have seen frequent resets in September 2026, driven by efficiency improvements, bug fixes, and major model launches such as GPT-6 Sol and Luna. These resets—often announced by OpenAI executives and tracked by community sites—include both global refreshes and banked credits granted after incidents or rollouts, with the most recent banked reset occurring on September 29 alongside DevDay feature updates like reusable cloud environments and security scans. Trader sentiment reflects how quickly new capabilities and lower API pricing increase demand, shortening intervals between resets while introducing purchasable instant refills for Plus and Pro users. Key upcoming catalysts include further GPT-6 iterations, potential 5-hour limit adjustments, and competitive pressure from rival coding agents that could prompt additional compensatory resets.
