What was claimed
AI just solved a decades old “holy grail” problem in probability theory that resisted elite mathematicians for decades. Anthropic AI generated a proof for percolation theory conjecture in dimensions 3-10 that could plausibly have been Fields Medal level work.
Our verdict
Needs cautionThe critical-percolation question is a longstanding and important open problem, especially in dimensions 3–10. “Holy grail” is informal promotional language rather than a precise mathematical classification. Reports describe a Claude-generated Lean development claiming to prove the relevant Kozma–Nitzan conjecture and thereby settle the open dimensions 3–10. However, available reports state that independent mathematical verification has not yet occurred.
