An Oct. 13 catalog update added the identifier azure_ai/claude-fable-5-5, but its price, context and capability fields were carried over from Claude Fable 5.1 because no specifications for Fable 5.5 were provided.

Fable 5.1 and Mythos 5.1 have system cards; no system card is listed for Fable 5.5. The catalog identifier does not confirm that Anthropic released a new model.
