Perplexity adds hybrid AI mode that keeps sensitive files on local Macs

Perplexity has launched a hybrid compute feature for its Computer agentic platform that splits AI tasks between cloud-based frontier models and smaller open-weight models running locally on Apple silicon Macs. Sensitive data is automatically routed to the on-device model via a locally-run 'Privacy Gate' classifier that detects personal information before anything reaches the cloud, without interrupting the task or losing context. The feature launches today for opted-in enterprise customers plus Pro and Max subscribers on Macs running macOS 15 or later.
