Anthropic’s redeployment announcement for Fable 5 mentions that if a request triggers the new safety classifier, the user will receive a notification and the request will automatically be handled by Opus 4.8 instead.
Could you please clarify how this will work inside Cursor? Specifically:
Will there be a visible banner or system message in the chat/composer interface?
Or is the switch completely transparent, so we only notice the difference through response quality?
Is there any log entry or status indicator we can check to confirm whether we’re actually using Fable 5 or Opus 4.8 for a given response?
We need to know this so we can accurately evaluate the answers and manage our workflow. Looking forward to your clarification. Thanks!
If Fable falls back to Opus 4.8, you will see a message:
Fable 5 hit a safety filter, and the conversation was automatically switched to Claude Opus 4.8. Start a new conversation to continue with Fable 5, or continue this conversation with Claude Opus 4.8.
