How to build scalable web apps with OpenAI's Privacy Filter

OpenAI's Privacy Filter, an open-source tool for detecting personally identifiable information (PII), has been introduced to the Hub, with capabilities to classify text into eight categories in a single pass over a 128k context. Three applications were developed using this tool, each demonstrating different functionalities: Document Privacy Explorer highlights PII spans in documents like PDFs or DOCX files; Image Anonymizer redacts PII in images and allows user annotations; and SmartRedact Paste provides a service to redact sensitive text before sharing, offering both public and private access URLs. These applications leverage Gradio's gradio.Server backend, which facilitates custom HTML/JS frontends and ensures consistent processing through its API. The Privacy Filter model features 1.5 billion parameters and achieves state-of-the-art performance on the PII-Masking-300k benchmark, with a flexible Apache 2.0 license.
