How To Build The Future

Sam Altman describes how conviction, focus, and willingness to adapt helped OpenAI pursue progress in AI despite skepticism and limited resources. He traces the development of OpenAI’s research from early bets on unsupervised learning and reinforcement learning to GPT models, and explains how customer use revealed their commercial potential. He argues that rapid advances in AI, abundant energy, and robotics could enable major gains in science and physical work. For startup founders, his advice is to build with AI, move quickly, and still create products and businesses that deliver real value.

Uncut Interview with Sam Altman on Masters of Scale [Audio]

Sam Altman describes how he went from a college project to founding Loopt, then joined Y Combinator after trying seed investing and deciding he preferred running companies. He argues that founders should take well-calibrated risks, build products people love, and get close to customers by doing work that does not scale. He explains how YC expanded into new fields and regions, and why clear vision, culture, frugality, and organizational structure matter as an organization grows. The conversation also covers hiring, luck, prioritization, and how Silicon Valley’s startup network may spread to other places.
