Today we’re launching Portable Computer on @NVIDIA DGX Spark.
Portable Computer is a fully local version of Perplexity Computer, where the entire runtime: orchestrator LLM, subagent LLM, agent harness all run on your local hardware. No cloud dependency.
When a task needs frontier reasoning, the orchestrator asks for approval before routing it to a frontier model in the cloud.
It's user-gated, PII-flagged, and text guidance only. Your sensitive documents stay on your device.
Portable Computer runs a post-trained and locally installed PPLX 27B model.
Qwen 3.8 27B is also available, with support for NVIDIA Nemotron 3.5 Lightning coming soon.
Portable Computer is available today for all Perplexity Pro and Max subscribers with an @NVIDIA DGX Spark.

multi-agent — Using several AI agents on one problem — splitting work in parallel, checking each other, or filling different roles like planner and reviewer.
agent harness — The scaffolding around a model that turns it into a working agent — the loop, the tools it can call, and the rules for when to stop.
AI agent — An AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.
Why it matters
The full AI agentAn AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.Full definition → runtime, orchestrator and subagents included, runs on local hardware with no cloud dependency, and any escalation to a frontier model requires explicit approval and sends text guidance only, keeping documents on the device.
