What it is good for
Good for tricky analyses, complex legal questions and anything where depth matters.
Hosting and operation
Claude Fable 5 runs internationally, at an operator in the USA: Anthropic.
If the operator is down, the model does not move to another jurisdiction.
Data processing
Data retention at the provider: 30 days. Anthropic stores prompts and answers for 30 days for abuse detection. With anonymization this only concerns placeholders.
Data is not used for training.
With anonymization on, anymize replaces personal data with placeholders before the request reaches the model.
Team admins can block such models with the governance rule “Only models with zero data retention”.

Availability
The model is in the model catalog but not in the default selection. An admin adds it under Governance > Models, in a solo account you do it yourself.
It is billed by usage via credits, not from your plan's allowance. Without credits left, you cannot use it.
Whether you may use it in a team is set by the “Model access” rule in the Governance Center.
