That is a ballsy move. Sounds like they're going to try and steal Google's thunder on the 9th. Wonder what they have planned - a version of chatgpt that isn't behind a login wall? Something that integrates with Bing? They probably have the compute infrastructure to pull it off.
Making ChatGPT part of Office 365, along with Bing integration, would be a baller move. In one move Google would be on the defensive for search, productivity and email.
