This week, OpenAI began rolling out web access and special plug-in apps to subscriptions users of GPT4.
Apps include Expedia and a PDF uploader and reader (which native GPT4 can't do). There are two app listings, "popular" (about 12 apps) and "all" (maybe 100 or more).
Under "all apps" there is one for Tic Tac Toe, so I guess you can use the $10 billion dollar resources of OpenAI to play tic-tac-toe.
