The conversation with Greg Brockman centers on the operating choices that shaped OpenAI from its founding through repeated scaling phases and internal tests. Brockman describes decisions made under uncertainty, where the mission of building broadly beneficial AGI dictated structure, resource allocation, and response to pressure rather than conventional startup norms.

Founding choices under uncertainty
Brockman left Stripe once he saw the core problem was not his own and identified AGI as the work he would pursue for decades. The initial group settled on three technical pillars at a Napa offsite: solve reinforcement learning, solve unsupervised learning, and scale to more complex tasks. They rejected a pure nonprofit path in 2017 after calculating required compute and concluding that only a for-profit structure could raise the necessary capital while keeping the mission intact. The decision was treated as a non-negotiable requirement for achieving the stated goal rather than a financial preference.

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?
