Your Mac is now part of Perplexity’s AI infrastructure

Perplexity now lets its AI shift parts of a task from the cloud to your Mac. That means private stuff can stay local, and your Mac starts looking like part of the AI backend.

Perplexity is trying to make the Mac do more of the heavy lifting for its AI agents. On Tuesday, the company launched Hybrid Compute, a feature in Perplexity Computer that can move pieces of the same task between cloud models and smaller models running on Apple silicon.
The setup starts in the cloud, then shifts local when sensitive information shows up. A Perplexity-trained Privacy Gate runs on the Mac and checks for things like names, addresses, account numbers, and secrets. If it finds something, the user can decide whether that part of the task should stay on the device. Before work starts, users can review what Perplexity wants to keep local and choose the model that will handle it.
At launch, the local options are Gemma E4B, Qwen3.6 35B-A3B, and a version of Qwen3.6 35B that Perplexity post-trained itself. More models are planned later. Perplexity also handles installation through its desktop app, so users do not need to open a terminal or assemble the model themselves.
There is also a cost angle. The app shows local CPU, GPU, and memory use, along with token counts, and Perplexity does not charge for tokens generated on the Mac. That makes local execution attractive for privacy and for inference costs, though the tradeoff is obvious: smaller local models can mean less capability than the company’s cloud models.
The hard part is context. Perplexity says Computer can move a step from the cloud to a local model without restarting the task or losing context, then combine the cloud and local work into one result. But it does not spell out exactly what context crosses the boundary, or how local output is filtered before it reenters the broader workflow. For enterprise customers, Perplexity adds company-wide rules for what stays local and a record of what leaves each device.
The feature requires a fairly strong Mac: at least 32GB of unified memory, Apple silicon, and macOS 15. It is available to Pro and Max subscribers and to enterprise customers. Perplexity also says users can start a task on an iPhone and hand off the local part to a Mac without starting over. The broader point is clear: the agent stack is no longer just cloud software, and Apple hardware is now part of the plan.
My take — AI-written commentary, not fact-checked reporting
This is the kind of move that makes the cloud crowd slightly nervous, which is healthy. If AI agents are going to rummage through private data, pushing some of that work back onto the device is common sense, not magic. The real tell is that the Mac now needs to earn its keep as infrastructure, not just as a nice place to browse email.
