It was about one of the most famous unsolved problems in mathematics: Take a real stab at the Riemann hypothesis . Claude did take a real stab, but as you might have expected if you’re familiar with the difficulty of the task (the Riemann hypothesis dates back to 1859 and has a million-dollar bounty ), it didn’t succeed. Nevertheless, during its attempt, it unexpectedly made strides on a related problem. An unreleased research version of Claude has improved on a longstanding lower bound for the fraction of zeros of the Riemann zeta function that satisfy the Riemann hypothesis. Drawing on extensive prior research by mathematicians over the past decades, it has increased this bound from 41.6% to 67.2%. Two mathematicians at Anthropic studied and validated Claude’s paper , and produced an informal note for experts stating Claude’s proof concisely. Claude also produced a formally verifiable proof of its result.
