Perplexity has introduced 'Portable Computer,' a platform for running AI agent workloads entirely on local devices, starting with Nvidia DGX Spark and RTX Linux PCs. This initiative aims to move AI agent tasks off the cloud, reducing token costs and enhancing privacy by keeping data on the user's machine.
“Perplexity has launched portable computer, a local AI agent platform running fully on device with zero token costs, starting with Nvidia D G X Spark and RTX Linux PCs.”
“We've basically brought the exact same UI to a fully local app said Nate, Perplexity's VP of engineering for infrastructure and enterprise, during a press briefing Monday.”
“An agent that runs for hours reviewing documents, verifying its own work and iterating on analysis would rack up substantial API bills in the cloud. On a device the user already owns, the marginal cost of those tokens approaches zero.”
