Anthropic says Claude found a subexponential algorithm for 3-SAT, contradicting the Exponential Time Hypothesis. Its repository includes an AI-written Lean proof, but no machine check confirms that the formal statement matches the paper. The result says nothing about practical SAT-solving performance.
