OpenAI’s discretionary resets of Codex weekly usage limits for paid users have accelerated around major model launches and efficiency fixes, with the most recent banked reset announced September 22 alongside GPT-6 Sol and Luna. That release highlighted broad capability gains in coding and writing tasks for the large language model while cutting API prices 50 percent, prompting OpenAI to credit resets to Plus, Pro, and Business accounts. Recent history shows median gaps of roughly three days between announcements from engineering lead Tibo Sottiaux, often tied to quality patches, new features like Astra, or usage spikes after rollouts. Traders monitor @thsottiaux posts and DevDay timing for signals, as resets remain ad hoc rather than scheduled and can shift with competitive pressure from other AI coding platforms.
