Details
- Perplexity is launching Portable Computer, a fully local version of its Perplexity Computer AI agent platform running entirely on NVIDIA DGX Spark hardware.
- The full agent runtime – including the orchestrator LLM, subagent LLM, and agent harness – executes on the user’s local machine with no default cloud dependency.
- For tasks that require frontier-level reasoning, the orchestrator first asks the user for approval before routing that specific step to a cloud frontier model.
- Cloud escalation is user-gated, flags potential personal identifiable information, and uses text-only guidance so sensitive documents and files remain on the device.
- Portable Computer currently runs a post-trained, locally installed PPLX 27B model, with Qwen 3.8 27B also supported and NVIDIA Nemotron 3.5 Lightning integration coming soon.
- The product is available today to Perplexity Pro and Max subscribers who have access to an NVIDIA DGX Spark system.
- The announcement highlights a local-first agent architecture aimed at reducing token-based cloud costs while improving privacy and control for users running complex AI workflows on their own hardware.
Impact
By moving Perplexity’s agentic Computer platform fully onto NVIDIA DGX Spark, Portable Computer strengthens the emerging trend of local-first AI agents that keep data and core workflows on customer hardware. This pressures cloud-only rivals such as OpenAI and Anthropic to offer more flexible, privacy-preserving deployments, while aligning with NVIDIA’s push for secure, always-on local agents on DGX-class systems.
