OpenAI will reveal a mysterious AI product on Monday. What we know, how to watch.

OpenAI is hosting a live demo of updates on Monday, May 13. But it won't be about GPT-5 or a search engine.

The announcement came from OpenAI's X account. In typically evasive fashion, the post only said the livestream would be about ChatGPT and GPT-4. But OpenAI CEO Sam Altman retweeted the news, saying "not gpt-5, not a search engine, but we’ve been hard at work on some new stuff we think people will love! feels like magic to me."

President and Co-Founder Greg Brockman also teased the announcement, saying, "Not GPT-5 or a search engine, but we think you’ll like it."

There were reports about a ChatGPT search engine being launched on Monday, which was especially juicy since Google I/O is happening the very next day. Followers are also eagerly anticipating the release of GPT-5 which is rumored to come out this summer and possibly sooner. However, a livestream event unrelated to a search engine or GPT-5 is unexpected.

Within minutes of Altman's confirmation that their announcement won't be about a search engine, Google stock shot up. So Google execs can breathe a sigh of relief... for now.

The genAI side of X is already abuzz with speculation. GPT-4.5? A Sora announcement? It's anybody's guess right now, but we're staying tuned.

The livestream will be on openai.com on Monday, May 13 at 1pm ET/10 am PT.
