I like to hate on Sam Altman, but this a low effort hit piece. OpenAI has a brilliant team lead by one of the best in the field [1]. The ones who left are all but one not technical people and happened months ago. And the one who left wanted to focus scarce compute on RL, which is a good gamble but not necessarily the right move.
Just yesterday from an internal email "Jakub moreso than Ilya has been making the research breakthroughs that are driving things forward, to the point that Sam promoted Jakub, and put him charge of the major model research directions." https://x.com/trajektoriePL/status/2018242446577086589
