Dean W. Ball on AGI

Said

“I think we crossed the AGI line with the GPT 5.2/Opus 4.5/Gemini 3 generation of models”

Ball places his claimed threshold crossing in late November or early December 2025 and expects future historians to agree. The timeline records when he made the statement, in March 2026, rather than moving the quotation to the retrospective date.

Model / system named
GPT-5.2, Claude Opus 4.5, Gemini 3
