The way it looks now, there's a shake out, with some other figures resigning / leaving.
It's about the not-for-profit thing. Sama (as he is known) has pushed too far towards commercial goals for the board's liking.
Worth knowing this much; Open AI was formed by Sama, Elon Musk and others and backed heavily by Venture Capitalists as a way to stop Facebook/Google/Microsoft dominating AI. If it was only in the hands of those companies, then none of those people would get a look in. They made a not-for-profit company to keep opportunity open for other companies, they want a rich competitive scene that they can invest in.
For now, Open AI have a substantial lead, and the product is going global. But the lead is precarious. And they still need more funding just to keep delivering. This means for Sam, and for others, it's time to up the commercial side, make deals, and engage in other competitive behaviour.
Some of the dealings will have gone down very badly with the not-for-profit board, who are sworn to defend other goals. His recent appearance in front of Congress (if you know how rich and ambitious he is, you'd have balked at the balls on the guy trying to pretend he's an ideologically driven person -- he really did not appear like a truthful guy, and his appearance is widely taken as being about him seeking 'regulatory capture', trying to influence lawmakers to act in ways that would help secure Open AI's commercial future). Last few days, he invited Microsoft's CTO to the Open AI dev day - this is a massive cultural insult to open source devs. He's talked up "new" products that seemingly are being a bit rushed to market, when they clearly are still struggling a bit to deliver GPT reliably to existing customers.
