Claude has a setting many people leave enabled by default.

It allows Fable → Opus fallback when a safety check is triggered. You can disable it in 3 places:

1. Chat
Open Settings → Capabilities
Find Switch models when a message is flagged
Turn the toggle off

2. Claude Code
Open Settings → Claude Code
Turn the same toggle off

3. Console
Run:
/config switchModelsOnFlag=false

If the safety check is triggered, Claude will stop the chat instead of continuing the response on Opus.
