Due to increased usage after the DevDay developers conference, OpenAI’s ChatGPT Plus signups are temporarily paused due to capacity challenges. Existing subscribers will continue to experience high-quality service, including features like GPT-4 Turbo and custom GPTs. ChatGPT Plus demand is so high that eBay listings now offer premium subscription months. Despite Google indexing over 300 public GPTs, a recent surge in demand led to outages, prompting the decision to halt new signups. Developers using the API may face fewer issues, but non-subscribers could experience frustration with limited access during this period.
