OpenAI is in hibernation now. If you look at OpenAI LLC articles of incorporation and address you will see them signaling this themselves. This is the hype cycle maneuvering.
Yeah I have the impression they are deliverying the bare minimum (or even less than that) for a big shocking release as soon as they can (but there goes 1 year and a half already)
I wonder if they want to go for-profit before major updates
