With the sudden simultaneous exits of Mira Murati, Barret Zoph, and Bob McGrew, I thought I'd update my tally of the departures from OpenAI, collated with how quickly the ex-employee had signed the loyalty letter to Sam Altman last November.
The letter was leaked at 505 signatures, 667 signatures, and finally 702 signatures; in the end, it was reported that 737 of 770 employees signed. Since then, I've been able to verify 56 departures of people who were full-time employees (as far as I can tell, contractors were not allowed to sign, but all FTEs were).
I still think I'm missing some, so these are lower bounds (modulo any mistakes I've made).
Headline numbers:
Reportedly, 737 out of the 770 signed in the end, and many of the Superalignment team chose not to sign at all.
Below are my current tallies of some notable subsets. Please comment with any corrections!
People from the Superalignment team who never signed as of the 702 leak (including some policy/governance people who seem to have been closely connected) and are now gone:
People from the Superalignment team (and close collaborators) who did sign before the final leak but are now gone:
Others who didn't sign as of the 702 leak (some of whom may have just been AFK for the wrong weekend, though I doubt that was true of Karpathy) and are now gone:
Notable other ex-employees:
