Amazon stole the show with its Alexa+ AI announcements on Wednesday, but OpenAI isn't waiting around for another chance in the spotlight.

The company behind ChatGPT announced on X on that it would livestream...something at 3 p.m. ET on Thursday. The livestream will be...somewhere, presumably, at that time. The tweet features zero other usable information of any sort, like a link or even a reference to which website the stream will be on. It could be on OpenAI's X account, or OpenAI's website, or maybe even OpenAI's YouTube page. None of them say anything about an upcoming livestream at the time of writing.
