“Mostly My Fault”: Inside Sam Altman’s High-Stakes Gamble to Save OpenAI’s Dominance OpenAI CEO Sam Altman admitted the company's last 12 months were not its best, saying 'We did not have our best last 12 months ever, which is mostly my fault,' and promised the next 12 months will be its best yet. OpenAI is spending heavily on compute, expanding into AI agents and products, and making infrastructure bets to counter rivals and secure its dominance. It’s been a little over a month since Sam Altman admitted something you don't often hear from the CEO of the company that helped kick off the generative AI boom. “We did not have our best last 12 months ever, which is mostly my fault.” Then he raised the stakes. Altman said OpenAI is about to have its best 12 months to date. A month later, that promise is worth looking at more closely because OpenAI isn't simply trying to release a better model. It's spending enormous amounts of money on compute, pushing deeper into AI agents and products, competing with increasingly capable rivals, and making bets on infrastructure that could shape how the company operates for years. So what changed? And more importantly, what exactly is Altman betting on to turn a year he largely blames himself for into OpenAI's best one yet?
