Anthropic's November 9 launch brought Fable and Mythos 5.2, not a new Opus
Anthropic's own news page, retrieved on November 11, lists Claude Opus 5.5 as its latest Opus, introduced on September 22. That is background, since it predates the window in which a qualifying model must appear. A qualifying release would need to be Opus 5.6 or higher, and Opus 5.5 itself does not count.
