When and how often the large AI labs ship new models. Release dates come from the Epoch catalogue rebuilt weekly; source-linked official releases and watcher discoveries remain marked as pending until Epoch adds them.

Release dates come from the Epoch AI notable-models export, rebuilt by the scheduled dataset refresh; recent source-linked official releases bridge known crawler misses, and the announcement-watcher agent adds models it has spotted on official announcement pages that Epoch has not catalogued yet (both are drawn with a dashed marker until Epoch adds them). One dot per distinct model version per lab; dates are publication/announcement dates, not API availability dates. More labs join the timeline as they are added to the tracked-lab registry.
