Only new models explicitly named 'Opus' by Anthropic, such as Claude Opus 5.1, Opus 5.5, Opus 6, etc., will count. Other names like Sonnet, Haiku, Fable, Mythos, etc., will not count unless Anthropic officially names them as Opus. The release date is based on the calendar date in U.S. Eastern Time.
