Codex rate limits will be reset for all paid subscriptions as part of a set of fixes aimed at reducing usage inefficiencies, according to a post from @thsottiaux. The update says the fixes are scheduled for tomorrow, while a separate efficiency approach is planned for work next week.

The usage issues identified in Codex

The post points to three sources of higher-than-intended usage:

  • Inefficiencies when images are used in long sessions with multiple compactions.

  • High p95+ usage associated with Computer History.

  • A feature designed to generate conversation titles using more usage than intended.

These findings came from a broader review by a tiger team, which is described as combing through the system and preparing fixes. The announcement presents the listed issues as some of the inefficiencies discovered, rather than as a complete account of every factor affecting usage.

Full usage reset for paid subscriptions

As part of the fixes planned for tomorrow, the update says usage will be fully reset for all paid subscriptions. That gives paid users a direct, near-term change alongside the technical work intended to improve efficiency.

The reset is therefore presented as part of the same response as the fixes, not as a separate product change. For users affected by current rate limits, the immediate practical impact is the promised refresh of their available usage.

More efficiency work is planned next week

The update also mentions a novel approach that could increase efficiency significantly. It is described as completely unrelated to the issues listed above, with work expected to begin next week.

That suggests the response has two stages: fixes for the specific usage problems already identified, followed by a separate effort that may improve efficiency more broadly. The post does not provide further details about how that approach will work, but it makes clear that the rate-limit work is continuing beyond the initial fixes and reset.
