OpenAI and Anthropic Each Claim an Internal Model Refuted the Exponential Time Hypothesis

Both labs say internal systems produced a result against a foundational conjecture in complexity theory — but independent review is still underway and the claims are unverified.

In a claim that warrants heavy caveats, OpenAI and Anthropic each reportedly said that an internal model refuted the Exponential Time Hypothesis, with independent expert review underway. The ETH is a foundational conjecture in computational complexity theory — a refutation, if real and verified, would ripple through large areas of theoretical computer science.
