OpenAI has reset usage limits for all paid Codex and ChatGPT users following a brief inference service disruption. Product lead Tibo confirmed that services have been fully restored and usage caps were refreshed to compensate for the outage's impact on subscribers. The company has also activated a backup Codex system to provide emergency support in the event of future primary service failures. This redundancy measure aims to maintain service continuity for paid users during potential infrastructure issues.
