Unlike the computer-controlling AI tool Perplexity launched earlier this year, the Portable Computer feature runs AI models fully locally and will ask for permission if it needs to access the cloud “for more advanced research and reasoning.” It will be available on Nvidia’s DGX Spark first, before rolling out to PCs with compatible Nvidia RTX GPUs.

But some question how well that data control is being enforced; hardware cost is also an issue

Running an AI model locally, Perplexity's new Portable Computer can deliver faster performance, tighter security, and lower costs. But it has some strict requirements.
