A deep dive into OpenAI’s Privacy Filter, benchmarking its PII detection performance against Tonic Textual on real-world datasets. We explore where the model succeeds, where it struggles, and how fine-tuning with labeled data impacts accuracy across domains like healthcare, legal, and web data. The post Benchmarking OpenAI’s Privacy Filter: What it gets right, and where PII detection still needs real data appeared first on Security Boulevard.
