OpenAI addresses model capacity limits with system enhancements and increased computing power

On October 16, 2026, IT Home reported that OpenAI's Codex/ChatGPT lead, @thsottiaux, announced on X that the team had deployed a series of updates and added more computing power to address the 'model capacity limit' error. The changes were part of OpenAI's 28-day continuous delivery plan, with the 11th update announcement highlighting the improvements and increased resources aimed at reducing the frequency of the error. Users have reported that the issue is not always due to the model being fully utilized. Some users with sufficient subscription limits and model switches still encountered the error repeatedly, while developers suspect it may be related to backend requests, session states, or resource scheduling. OpenAI's team has optimized the system and increased computing power to reduce the occurrence of the error. If the error persists, tasks should now automatically continue rather than being stuck in an error state. The team also invited users still experiencing the issue to provide feedback for further investigation.
