Frontier AI laboratories have said that their models refuted the Exponential Time Hypothesis — a mathematical conjecture about the computational complexity of problems. TechCrunch AI reports this.

The publication also spoke with a computer scientist at MIT, who was tasked with explaining OpenAI's latest finding. The description provided does not specify which models were used or what the verification result was.

The significance of this news is hard to gauge: the available materials lack technical details, proofs of refutation, or independent confirmation. The next important signal will be a full explanation with verifiable results.
