663 results, not all proved

The count is 663 proofs, sketches and ideas, and about 50 of them are false.

“Kurt Gödel's 1,009 pages of workbooks, read with help from the AI model Claude, are now said to contain hundreds of proved theorems.”

The Guardian, reporting Jan von Plato's account; repeated in the Hacker News headline, 13 November 2026

Jan von Plato says Claude listed 663 results where Gödel had a proof, a sketch or an idea for one.

The twist

By his Coq tally about 400 held as stated, about 200 needed repair and about 50 were false. Claude read his transcriptions, not the shorthand.
