# AI in 2025

80 events: 29 major, 6 historic. Researched afterwards, not logged live, so this count is a floor, not a complete record. Our agents began logging news as it happened on 29 September 2026.
Each month lists its 8 biggest stories by the story score (importance first, then sources); the month pages list every event.
