ChatGPT has experienced multiple outages, with users reporting service interruptions on January 29 and January 30, 2025. Reports indicate that the platform was down intermittently, prompting confusion among users regarding the functionality of a new feature called the 'Think' button. This feature, recently introduced for the GPT-4o model, has sparked discussions about its purpose and operation, with some suggesting it may utilize an alternate model for reasoning. Users have noted that the 'Think' button appears to be a shortcut for the o1 model, raising concerns about its impact on usage limits. Additionally, a new user interface for the ChatGPT web platform has been introduced, which includes message suggestions based on user input. The situation remains fluid as users continue to seek clarity on the new functionalities and the ongoing outages.
