100-word summary
OpenAI just released Privacy Filter, a free open-weight model that detects and redacts personal information locally before data leaves your laptop. The tool spots eight types of sensitive info (email, phone, addresses) across documents up to 128,000 tokens long and hits 96% accuracy on standard benchmarks. It's tiny enough to run on-device with just 50 million active parameters, meaning your customer support logs or training data never hit external servers. Companies can fine-tune it to match their own privacy rules. The catch: it's not perfect, especially with rare identifiers or short snippets, so high-stakes use still needs human oversight.
