OpenAI's Privacy Filter is a 1.5-billion-parameter open-weight model trained specifically for detecting and redacting personally identifiable information (PII) from text. Released today under the Apache 2.0 license, it achieves over 96% F1 score on standard PII detection benchmarks and is compact enough to run locally on consumer hardware — no API required. The model handles standard PII categories (names, emails, phone numbers, SSNs, addresses) plus context-dependent identifiers like account numbers, medical record IDs, and quasi-identifiers that become sensitive in combination. It's designed to run as a pre-processing filter before text hits larger models, letting teams handle sensitive data without sending it to the cloud. Releasing this under Apache 2.0 is a meaningful move. Most enterprise PII tools are expensive, closed, and API-gated. A small, accurate, locally-deployable open-weight model changes the economics for startups, researchers, and developers building with sensitive data. It slots cleanly into data pipelines, agent pre-processors, and document handling workflows.
Reviewer scorecard
“Syncs secrets to every platform automatically. The CLI and dashboard make secret management painless.”
“A 96%+ F1 PII model at 1.5B parameters that runs locally and ships under Apache 2.0 is immediately useful. Drop it at the front of any data pipeline that handles user-generated content, medical records, or financial data. The size means you can run it on CPU if needed. This is the kind of open-source release that actually changes what's practical to build.”
“Simpler than Vault for most teams. The universal sync to deployment platforms is the killer feature.”
“96% F1 sounds great until you're in healthcare or finance where the 4% miss rate is a compliance catastrophe. PII detection at production scale requires near-perfect recall, not just high F1. And 'context-dependent quasi-identifiers' are notoriously hard — I'd want to see the breakdown by PII type, not just the aggregate score, before trusting this in a regulated environment.”
“Secrets management will be invisible infrastructure. Doppler is making that future real for teams of all sizes.”
“The open-source PII filtering layer is missing infrastructure in the AI stack. As agents process more sensitive documents, the ability to strip PII before data hits any external model becomes critical. This is the kind of foundational tooling that enables an entire category of privacy-preserving AI applications — especially in healthcare, legal, and finance.”
“For anyone building tools that handle user-submitted content, this is a gift. Running PII redaction locally before storing or analyzing content is good practice that was previously too expensive to implement at scale. Apache 2.0 means no legal friction for commercial use.”
