OpenAI's policy: a model snapshot remains available until its shutdown date, after which requests are routed to a recommended replacement (or fail). Dates are printed exactly as on the page. "Deprecated on" = announcement date; "Retires on" = shutdown date. Where the page only states an announcement-level date for a feature group, that date is used as deprecatedOn.
