2 min readKey summary
A tutorial shows how to build a PII detection and redaction pipeline with OpenAI’s Privacy Filter.
It sets up dependencies, loads a pretrained token classification model, and normalizes entity labels.
The workflow extracts sensitive spans, replaces them with placeholders, and prepares redacted outputs for analysis.
The approach helps teams automatically mask private data for compliance and safer batch processing.
