Field notes
The page walks through an appointments dataset with 14,976 rows and suggests questions such as who might miss an appointment. Its example churn model is a useful counterexample to accuracy-as-proof: a 96% result loses to a 97% baseline that predicts nobody leaves. The site says models can be versioned and that retraining does not overwrite prior versions. It also describes testing document-based answers against questions drawn from files the model has not seen.
