OpenAI’s Codex team, led by engineering lead Thibault Sottiaux, drives trader sentiment through discretionary weekly usage resets tied to compute management, bug fixes, and product milestones rather than fixed schedules. The most recent catalyst was the September 22, 2026, release of GPT-6 Sol and Luna models, which included a banked reset for Plus, Pro, and Business users alongside a 50% API price cut to handle surging demand. Earlier 2026 resets addressed background token overuse from auto-review features, temporary removal and restoration of 5-hour rolling windows for Plus subscribers in July–August, and milestone celebrations such as reaching 25 million active users. High adoption of advanced coding workflows keeps pressure on capacity, making further resets likely around major model updates or efficiency patches, though exact timing remains unpredictable.
