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. The most recent Anthropic launch in the evidence is Claude Fable 5.2 and Claude Mythos 5.2, dated November 9. That announcement, an official record, tells users to start with Claude Opus 5.5, which it calls the strongest daily driver, and to move up to Fable or Mythos or down to Sonnet 5.5 or Haiku 5.5 as the work requires. Opus 5.5 is still the Opus recommendation as of that post, which does not point to a successor being imminent. Platform release notes add to that picture. An October 30 entry deprecates fast mode for Claude Opus 4.8 and tells developers to migrate to Opus 5.5. Claude Haiku 5.5 arrived on October 7. Anthropic's pages describe a 5.5 family built around Opus 5.5. That leaves a little over two weeks to November 30. The forecast leans toward no qualifying release in that time, though a surprise launch cannot be excluded from this research. The evidence does not give a date or signal for an Opus 5.6. Watch for any Anthropic announcement of a new Opus model on its news page or the platform release notes before November 30.
