Chronology

Timeline milestones are source-linked historical anchors. The 1,002-record catalog is broader than this chronology; many records remain baseline entries pending deeper provenance and lifecycle audits.

Timeline + lineage

History answers when major computing and AI milestones happened. Lineage answers what led to what—model generations, rebrands, fine-tuning branches and research influence.
