💡 [SUGGESTION] The PR description notes there's no explicit "default" flag in the server catalog for Fable 5.1 (or Fable 5) — high is inferred here by matching the Fable 5 row shape. That's a reasonable inference, but since a wrong "Default effort" label would misinform readers about actual out-of-the-box behavior, it's worth a quick confirmation against the client's actual default selection (e.g. the model picker default) before merge, rather than relying solely on precedent-matching with Fable 5.

:::caution
Anthropic requires data retention for Claude Fable 5 for safety, abuse monitoring, and compliance reasons, so it is **not available under Zero Data Retention (ZDR)**. This requirement is specific to Claude Fable 5 and doesn't change the ZDR behavior of any other supported model. For Enterprise teams, the model is off by default and a workspace admin must enable it — see the [Admin Panel](/enterprise/team-management/admin-panel/#models-settings) and the [Security overview](/enterprise/security-and-compliance/security-overview/#zero-data-retention-zdr).
