- On September 22 it released Claude Opus 5.5, calling it the first model in the new 5.5 family, and Sonnet 5.5 and Haiku 5.5 followed.
- No Fable successor has been announced.
- This market asks when Anthropic will release its next Claude Fable model: any model Anthropic names "Claude Fable" with a version number above 5.1 (for example Fable 5.2, 5.5 or 6).
- What counts as a release: Anthropic announces the model on anthropic.com (news post or model page) AND it is generally available to the public in at least one of: the Claude API, claude.ai, or a major cloud platform (Bedrock, Vertex, Foundry).
- A limited preview for vetted organizations only (like the restricted Mythos access) does not count.
