Perplexity CEO announces rollout of hybrid compute feature for Mac application
Artificial intelligence firm Perplexity introduced hybrid compute for all users of its Mac application, enabling tasks to be divided between cloud infrastructure and local devices to protect sensitive records.
Artificial intelligence company Perplexity is expanding its Mac application with a hybrid compute feature, announced by CEO Aravind Srinivas. This new system allows tasks to be processed on both cloud servers and local devices, safeguarding sensitive data. Speaking on X, Srinivas explained that the feature enables the app to manage local models that can operate on Mac computers, especially for tasks involving private documents like medical records, tax returns, or legal cases.
Srinivas highlighted the distinction between traditional AI agent apps and the new hybrid system, pointing out the advantage of moving token consumption to Apple Silicon on Macs without incurring additional costs for those tokens processed locally. This approach not only enhances performance but also greatly improves user privacy. He further revealed that Perplexity is open-sourcing the PII classifier used to determine when tasks should be handled locally, adding a layer of transparency to the system.
The hybrid compute mechanism divides operations between cloud-based reasoning, web searches, and planning, and local models dealing with confidential information. A dedicated privacy gate on Mac devices scans files for personal identifiers before they leave the system, masking details or declining tasks when necessary. This feature is designed to comply with regulatory and confidentiality requirements in sectors such as finance, legal services, and advertising.
For example, investment teams can leverage cloud-based cloud searches while examining sensitive transaction data on local devices. Legal professionals can browse case law online while keeping client-privileged documents strictly on their local drives. Enterprise administrators of these systems will have centralized control over file management, data masking, and user consent, along with audit trails for monitoring data movements.
Users can even request tasks remotely through their iPhone, which triggers processes on their Mac hardware.
The hybrid capability is currently accessible to Pro, Max, and Enterprise subscribers, and launches with three local models: Gemma 4 E4B, Qwen3.6 35B-A3B, and a proprietary Perplexity model. To run this feature, Mac users need an Apple Silicon device operating on macOS 15 or later, equipped with at least 24 gigabytes of unified memory.
