Perplexity open-sources PII classifier for hybrid compute privacy

perplexity_ai · x · 2026-09-01

Perplexity has open-sourced the PII (Personally Identifiable Information) classifier used in the 'hybrid compute' setup of its Mac app. This model detects privacy information before it leaves the device, deciding whether to run the step locally, send it to the cloud, or skip it entirely. This architecture allows cloud models to handle search and reasoning while sensitive file processing is offloaded to local models, ensuring data privacy.
