There are L5 engineers with 3 YOE making 900k+ at OpenAI right now. Tough to say what they're paying their PhDs, but I'd imagine it's similarly nutty.

FAANG pays exceptionally well (I'd know), but what's being offered at OpenAI is eye-popping, even for SWEs. I think they're trying to dig their moat by absorbing the absolute best of the best.
