Intended Uses & Limitations

Use this model for:

Low resource environmens
Redacting PII in customer support logs, dev/test environments, API traces and articles
Real-time hints in form fields or data entry systems

Limitations:

English-focused; other languages will degrade
Domain drift is real: audit on your own data
