CEO Sam Altman conveyed the decision due to an overwhelming surge in usage after OpenAI’s DevDay, where new APIs were introduced.
Altman mentioned that the platform’s capacity has been exceeded, impacting user experience.
While new registrations are paused, users can opt to be notified when subscriptions reopen within the app.
The move comes after a week of service disruptions and outages caused by high demand and distributed denial-of-service attacks.
Altman acknowledged the significant increase in ChatGPT Plus usage post-DevDay, leading to the decision to pause new sign-ups.
This strategic move aims to ensure a smoother experience for existing users and address capacity constraints.
The temporary pause may alleviate issues faced by developers working with generative pre-trained transformers (GPTs) and using the API, such as difficulties in saving GPT drafts.
However, it could also result in a temporary decrease in new GPT users, as access to GPTs is currently exclusive to ChatGPT Plus subscribers.
Elon Musk has also joined the arena with his AI chat program, “Grok.”
