Exponential Time Hypothesis Refuted? What Frontier AI Labs’ Claim Means
OpenAI and Anthropic say their models independently refuted the Exponential Time Hypothesis, a 27-year-old pillar of complexity theory. This guide explains what ETH claims, what a subexponential 3-SAT algorithm does and does not change, who is checking the proofs, and what the verdict means for algorithms, cryptography and AI-generated science.
