Every LLM feature needs a kill switch
Community description: A model provider had a bad Tuesday, and our summarisation feature spent four hours returning empty strings to customers because nothing between the API and the user knew what to do with a 529. The feature now has a kill switch, a fallback, a budget and a canary. Without those four it was a demo.

Automated excerpt
Nobody had decided what the feature should do when the model isn't there. Flag summaries. enabled turns the feature off, the summary box disappears, customers see nothing broken. Flag summaries. model picks the model, current value in the flag UI.
