⚠️ Important: This model is intended as an assistive tool, not a replacement for human review. - False Negatives: Some PII may not be detected; always verify critical applications - Context Sensitivity: Performance may vary with domain-specific terminology - Challenging Categories: `occupation`, `time`, and `sexuality` have lower F1 scores - Language: Primarily trained on English text
