Sam Altman says OpenAI will own 'well over 1 million GPUs' by the end of the year — ChatGPT maker continues to expand rapidly

Sam Altman.

OpenAI CEO Sam Altman isn’t exactly known for thinking small, but his latest comments push the boundaries of even his usual brand of audacious tech talk. In a new post on X, Altman revealed that OpenAI is on track to bring “well over 1 million GPUs online” by the end of this year. That alone is an astonishing number—consider that Elon Musk’s xAI, which made waves earlier this year with its Grok 4 model, runs on about 200,000 Nvidia H100 GPUs. OpenAI will have five times that power, and it’s still not enough for Altman going into the future. “Very proud of the team...” he wrote, “but now they better get to work figuring out how to 100x that lol.”
