OpenAI Co-Founder: AI Goes Parabolic! Here's What's Next | Greg Brockman
The Knowledge Project
Hidden Reasoning Protects Advantage and Safety
Greg Brockman explains why OpenAI stopped showing chain-of-thought, citing distillation risks and the need to preserve faithful internal reasoning signals.
The AI race, the future of AGI, and the inside story of OpenAI.
Greg Brockman is the co-founder of OpenAI. This is the most detailed first-person account he has given of the 72 hours after Sam Altman was fired, how OpenAI started, and the future.
Greg explains how the original Napa offsite produced the three-step technical plan OpenAI has followed for a decade and the real reason OpenAI had to abandon its pure nonprofit structure.
He then walks through the 72 hours after Sam Altman was fired: where he was when he got the board call, why he quit the same day, how the "Phoenix" backup company was designed at Sam's house the next morning, and the moment Ilya Sutskever's tweet changed everything.
From there, the conversation turns forward: whether we're in a global AI race, how much of OpenAI's own code is now written by AI ("it's hard to know what percent is not"), why OpenAI stopped showing reasoning traces, what a compute-constrained world means for who gets access to AGI, and Greg's answer to the question everyone is really asking: What happens to your job?
