Many fears of an AI bubble had hit a fever pitch at the start of this year when Chinese start-up DeepSeek released a competitive reasoning model.

During a dinner with a small group of reporters, OpenAI CEO Sam Altman cautioned that investment in AI is moving too fast.

Even if an influx of funding is contributing to an AI bubble, Altman says that OpenAI still intends to spend heavily, up to "trillions of dollars on datacenter construction in the not very distant future," according to CNBC. The company is betting on growing demand to bolster spending.
