Codex hits 3 million weekly users

Strong growth, and the limit-reset mechanic is a clever way to turn usage milestones into a visible product perk.

• –This reads like an engagement lever as much as an ops decision: users get a tangible benefit as adoption climbs.
• –Resetting limits at every million users creates a simple narrative loop that reinforces momentum and makes growth feel communal.
• –The update implies Codex demand is high enough that usage policy is now part of the product story, not just backend plumbing.
• –For power users, the practical takeaway is that capacity may stay more forgiving as the user base expands, at least through the next milestones.
