Perplexity has released Portable Computer, a fully local version of its Perplexity Computer, for NVIDIA DGX Spark. The entire runtime, including the orchestrator LLM, subagent LLM, and agent harness, runs on the user's local hardware with no cloud dependency. When a task requires frontier reasoning, the orchestrator asks for approval before routing it to a cloud-based frontier model. The system is user-gated, PII-flagged, and text guidance only, keeping sensitive documents on-device. It runs a post-trained, locally installed PPLX 27B model; Qwen 3.8 27B is also available, with NVIDIA Nemotron 3.5 Lightning support coming soon. Availability is limited to Perplexity Pro and Max subscribers who own a DGX Spark.
