OpenAI’s CEO says he’s scared of GPT-5

OpenAI CEO Sam Altman said testing GPT-5 left him scared in a recent interview
He compared GPT-5 to the Manhattan Project
He warned that the rapid advancement of AI is happening without sufficient oversight

OpenAI chief Sam Altman has painted a portrait of GPT‑5 that reads more like a thriller than a product launch. In a recent episode of the This Past Weekend with Theo Von podcast, he described the experience of testing the model in breathless tones that evoke more skepticism than whatever alarm he seemed to want listeners to hear.

Altman said that GPT-5 “feels very fast,” while recounting moments when he felt very nervous. Despite being the driving force behind GPT-5's development, Altman claimed that during some sessions, he looked at GPT‑5 and compared it to the Manhattan Project.

Altman also issued a blistering indictment of current AI governance, suggesting “there are no adults in the room” and that oversight structures have lagged behind AI development. It's an odd way to sell a product promising serious leaps in artificial general intelligence. Raising the potential risks is one thing, but acting like he has no control over how GPT-5 performs feels somewhat disingenuous.

Analysis: Existential GPT-5 fears

What spooked Altman isn’t entirely clear, either. Altman didn’t go into technical specifics. Invoking the Manhattan Project is another over-the-top sort of analogy. Signaling irreversible and potentially catastrophic change and global stakes seems odd as a comparison to a sophisticated auto-complete. Saying they built something they don’t fully understand makes OpenAI seem either reckless or incompetent.

GPT-5 is supposed to come out soon, and there are hints that it will expand far beyond GPT-4’s abilities. The “digital mind” described in Altman’s comments could indeed represent a shift in how the people building AI consider their work, but this kind of messianic or apocalyptic projection seems silly. Public discourse around AI has mostly toggled between breathless optimism and existential dread, but something in the middle seems more appropriate.

This isn't the first time Altman has publicly acknowledged his discomfort with the AI arms race. He’s been on record saying that AI could “go quite wrong,” and that OpenAI must act responsibly while still shipping useful products. But while GPT-5 will almost certainly arrive with better tools, friendlier interfaces, and a slightly snappier logo, the core question it raises is about power.

The next generation of AI, if it’s faster, smarter, and more intuitive, will be handed even more responsibility. And that would be a bad idea based on Altman's comments. And even if he's exaggerating, I don't know if that's the kind of company that should be deciding how that power is deployed.
