OpenAI Releases Privacy Filter: Open-Source 1.5B-Parameter PII Redaction Model

OpenAI released Privacy Filter, a 1.5-billion parameter open-source model designed to detect and redact personally identifiable information in web browsers. The model uses a distilled decoder architecture that runs with only 50 million active parameters, enabling it to operate efficiently in browser environments without requiring server-side processing. By releasing Privacy Filter as open-source software, OpenAI makes enterprise-grade PII protection accessible to developers and organizations. The tool represents a significant technical achievement in model compression and addresses growing concerns about data privacy in digital applications.
