• AI Brief, 24 October 2026: the comparison table that undersold its own model

  24 October 2026

An independent run published the same day scores it higher than Moonshot's own table does, because the table compared one self-run harness against rivals' best-ever published figures. Moonshot also published the cyber-capability score of the checkpoint it chose not to ship: 90.5% against the shipped model's 81.0%.
