ChatGPT maker OpenAI is no longer taking new sign-ups for its latest ChatGPT Plus models amid a demand overload. As announced by company CEO Sam Altman, this goes to show the public’s growing interest and need for AI technology.

“The surge in usage post devday has exceeded our capacity and we want to make sure everyone has a great experience”, announced Altman in a tweet yesterday. He also added that users who have tried to sign up during this time will be notified once the subscriptions are open again.

OpenAI DevDay Announcements

This surge in demand has to do with OpenAI’s recent announcement of an enhanced version of its AI model, GPT 4 Turbo, as well as a list of other features and improvements. GPT 4 Turbo features a much bigger context window of 128,000 tokens per prompt, up from the previous limit of 32,000 tokens.  It also has a more recent knowledge cut-off date of April 2023 and promises a more reliable and faster response.

GPT 3.5 Turbo has received upgrades as well, including a default context window of 16K tokens and the same knowledge cut-off date as GPT 4 Turbo. OpenAI announced price reductions for all its AI models too.

ChatGPT Plus users will be able to make their own GPTs tailored to specific use cases. For instance, an AI chatbot could be designed to answer questions related to complicated board games. Custom GPTs will have a dedicated marketplace called the GPT Store where verified builders can share their work and browse countless other custom chatbots.

These announcements come from OpenAI’s first-ever developer conference last week during which Altman revealed that ChatGPT is now used by over 2 million developers worldwide and has hit 100 million weekly active users. Over 92% of Fortune 500 companies are also using ChatGPT to build their products.

The executive said: “What’s incredible about that is we got there entirely through word of mouth. People just find it useful and tell their friends. OpenAI is the most advanced and the most widely used AI platform in the world now.”

These figures not only depict the extensive integration of AI technology but also underscore its capacity to revolutionize diverse industries.
