OpenAI has driven recent Codex usage limit resets through a pattern of milestone celebrations and engineering fixes, most recently granting full banked resets on September 5 tied to the ahead-of-schedule Astra rollout for paid ChatGPT plans, following the August 31 reset after hitting 25M active users. Engineering lead Tibo Sottiaux has repeatedly announced these adjustments on X to address excessive token consumption from features like auto-review, background suggestions, and multi-agent workflows in models such as GPT-5.6/Sol, improving efficiency by 10-50% while restoring smoother 5-hour caps for Plus subscribers alongside the weekly quota. This approach supports competitive positioning against other AI coding platforms by sustaining generous access, encouraging referrals, and managing compute loads amid rapid adoption. Traders should watch for further Astra-related updates or user-growth announcements next week, as these events have consistently triggered resets in recent months.
