OpenAI Privacy Filter Demo Apps — Gradio Server & 1.5B Model

AI Impact Summary

OpenAI has released Privacy Filter, an open-source PII detector, and provided three demo applications built around it. These include a Document Privacy Explorer, an Image Anonymizer, and a SmartRedact Paste, all leveraging Gradio Server for deployment. The core of the solution utilizes a 1.5B-parameter model with 50M active parameters, achieving state-of-the-art performance on the PII-Masking-300k benchmark. The demo applications demonstrate a streamlined workflow for redaction, utilizing a single forward pass over a 128k context and showcasing the efficiency of Gradio Server for concurrent requests and zero GPU allocation.
