DeepMind study: most AI 'solutions' to open Erdős problems were already in the literature

Researchers used Gemini to screen 700 problems listed as open in Thomas Bloom's Erdős Problems database and settled 13, but only five appeared to be new; eight had existing solutions found in the literature. The authors concluded many problems were open through obscurity rather than difficulty and warned of 'subconscious plagiarism' when models work at scale, stressing human expert checking.
