Summary
Perplexity introduced Hybrid Compute for its Mac app, letting a Perplexity Computer task run partly on frontier cloud models and partly on a local model, with an on-device PII classifier that redacts sensitive data before anything leaves the machine. It is available to Pro, Max, and Enterprise users on Apple silicon Macs.
What changed
On September 1, 2026 Perplexity shipped Hybrid Compute on Mac. The cloud handles frontier reasoning, web search, and planning while a local model processes private files, sensitive data, and on-device actions; Perplexity Computer coordinates the whole workflow. An on-device PII classifier swaps names, addresses, and account numbers for stand-ins before a task is sent, then restores them in the answer. It launches with Gemma 4 E4B, Qwen3.6 35B-A3B, and a Perplexity model, requires Apple silicon with macOS 15+ and 24GB+ unified memory, and is available to Pro, Max, and Enterprise.
Why it matters
It turns the local-versus-cloud tradeoff into an automatic split rather than a user choice, letting agentic work touch private files while keeping sensitive data on device. That privacy-by-architecture pitch targets exactly the enterprise and regulated users who hesitate to hand files to a cloud assistant, and pressures rivals to offer verifiable on-device handling.
