Turns out it was 5 or a vague reading of 1. Ilya Sutskever (cofounder/board member) had safety debates with Altman, driving Ilya to convince other board members it was in their best interest to play hard-ball with Altman over safety concerns.
Looks like a board over-reach considering the amount of investors who have come out favoring Altman... if Altman returns it is likely the board will be overhauled.
