Perplexity launches Portable Computer, a local-first agent that keeps private data on-device

Perplexity Portable Computer

Perplexity released Portable Computer, a local-first version of its Computer agent that runs on the NVIDIA DGX Spark. It uses Qwen 3.8 27B or PPLX 27B to handle files, code, and workflows entirely on-device—no credits burned and private data stays put. When a task needs web search or frontier reasoning, the local orchestrator asks permission before escalating to the cloud. Available now for Pro and Max subscribers on Linux; Windows support is coming soon.

Why it matters: Perplexity partnered with NVIDIA to put Computer on the DGX Spark for local execution — novel product shape with concrete privacy controls. Score held at 78 because it's an early hardware-tied launch and the post doesn't go deep on real-world usability yet.

The reason this is worth a look: it turns "local agent" from a concept into something you can actually use. Perplexity partnered with NVIDIA to run its Computer agent on the DGX Spark, a desktop box with 128 GB unified memory. It ships with Qwen 3.8 27B or PPLX 27B, handling files, code, and workflows entirely on-device. When a task needs web search or frontier reasoning, the local orchestrator asks permission before escalating to the cloud.

I'd discount the hype a bit—Linux only for now, Windows is "coming soon," and the DGX Spark isn't cheap. But the direction is clear: own your compute, keep sensitive data local, and stop burning credits on high-volume tasks. NVIDIA Nemotron 3.5 Lightning 30B is on the way, and dictation runs locally with Nemotron ASR so audio never touches the cloud.

Don't read this as "local models replace the cloud." It's a hybrid play: sensitive and high-frequency work stays on-device, cloud handles search and heavy reasoning only when you say yes. For anyone dealing with private codebases, term sheets, or client comms, that's a real option.
