Perplexity Portable Computer Brings Local AI Agents to DGX Spark.

Perplexity is bringing its Computer agent off the cloud and onto local hardware. The company announced on LinkedIn that Portable Computer runs the full agent runtime on NVIDIA DGX Spark, allowing eligible users to work with sensitive documents without sending those files to a cloud service.

The release covers more than local model inference. Perplexity says the orchestrator model, subagent model and agent harness all execute on the DGX Spark. That makes Portable Computer a locally operated version of Perplexity Computer rather than a thin desktop interface that still depends on remote infrastructure.

Portable Computer is available as of August 25, 2026, to Perplexity Pro and Max subscribers who have an NVIDIA DGX Spark.

Portable Computer uses PPLX 27B, a post-trained model installed locally. Perplexity is also making Qwen 3.8 27B available as an alternative, while support for NVIDIA Nemotron 3.5 Lightning is listed as coming soon. The announcement does not provide a date for that additional model.

The local-first design does not completely remove access to cloud models. If a task requires what Perplexity calls “frontier reasoning,” the orchestrator can request permission to route the task to a frontier model in the cloud. The request is user-gated, so cloud processing should not begin without approval.

Perplexity also describes the handoff as PII-flagged and limited to text guidance. Sensitive documents remain on the device, according to the company. The announcement does not detail exactly how personally identifiable information is detected, what text is included in an approved request, or whether administrators can impose broader organization-level restrictions.

The resulting workflow has three notable characteristics:

• Local execution: The orchestrator, subagents and agent harness run on the DGX Spark.
• Explicit cloud approval: Harder tasks can be escalated only after the user approves the request.
• Document separation: Perplexity says sensitive source documents stay on the local device, even when cloud guidance is requested.

For small businesses, agencies and professional teams, agentic AI creates a difficult trade-off. An agent becomes more useful when it can inspect contracts, internal research, customer records or financial documents, but those are also the materials teams may be least willing to upload to a third-party cloud.

Portable Computer is Perplexity’s attempt to separate document access from frontier-model reasoning. Routine work and document handling can remain local, while a cloud model can provide limited assistance when the installed model is not sufficient. The approval step also gives the operator a decision point that is often missing from fully cloud-based agent workflows.

There are practical constraints. DGX Spark is specialized AI hardware, so this is not a local mode intended for an ordinary business laptop. Access also requires a Pro or Max subscription. Perplexity has not disclosed separate Portable Computer pricing, minimum storage requirements, model download sizes or performance benchmarks in the supplied announcement.

The launch also broadens the company’s approach to Computer. Other recent updates have concentrated on bringing more information and models into cloud workflows, including licensed business-data connectors and U.S.-hosted DeepSeek V4 Pro. Portable Computer moves in the other direction, putting the execution environment beside the user’s data and making cloud access an optional, visible step.

For organizations evaluating it, the key question will be whether local PPLX 27B or Qwen 3.8 27B can handle enough day-to-day tasks without frequent escalation. Perplexity has established the architecture, but real-world benchmarks and more detailed controls will determine how useful that architecture is for sensitive production work.

What is Perplexity Portable Computer?

Perplexity Portable Computer is a locally running version of Perplexity Computer for NVIDIA DGX Spark. Its orchestrator model, subagent model and agent harness run on the user’s hardware rather than depending on Perplexity’s cloud runtime.

Can Portable Computer use cloud AI models?

Yes, but only as an approved fallback for tasks requiring frontier reasoning. Perplexity says the system asks the user before routing text guidance to a cloud model, flags personally identifiable information and keeps sensitive documents on the device.

Who can use Portable Computer, and which models does it support?

It is available to Perplexity Pro and Max subscribers with an NVIDIA DGX Spark. It runs a locally installed PPLX 27B model, also supports Qwen 3.8 27B, and is expected to add NVIDIA Nemotron 3.5 Lightning support later.
