01
What Perplexity Portable Computer is
Perplexity announced Portable Computer on August 25, 2026 as a local-first version of its Computer agent. The launch puts the orchestrator, planner, tool router, scheduler, durable task queue and local search index on NVIDIA hardware instead of requiring every workflow step to run remotely.
Perplexity describes the system as hybrid rather than universally offline: local work can stay on the device, while tasks that need current web information, connected apps or stronger remote reasoning can escalate to cloud capabilities with user permission.
02
Launch hardware and operating system
The first release targeted NVIDIA DGX Spark on Linux. Perplexity now also supports Windows and Linux PCs with a supported NVIDIA RTX GPU and at least 24GB of VRAM; access is available to eligible Perplexity Pro and Max subscribers.
03
Which local models does it use?
On NVIDIA DGX Spark, Portable Computer can use PPLX 27B or Qwen 3.8 27B. On supported Windows and Linux RTX PCs, the current product page lists PPLX 27B; Qwen 3.8 27B is not available on RTX PCs.
Perplexity still lists NVIDIA Nemotron 3.5 Lightning as coming soon. Treat it as announced future support until it is exposed in the released product.
04
What stays local
Perplexity says local models can read and search local files, work across documents and code, take actions on the device and keep jobs running. Dictation can also run locally using NVIDIA’s Nemotron 3.5 ASR model.
Code and tool execution are described as running inside isolated sandboxes with controlled access to files and connected apps. That is an important security boundary, but users should still review destructive actions and external writes.
05
When Portable Computer uses the cloud
A task can escalate to Perplexity search, research modes, browser tools, connected apps or more than 15 frontier models when the local system needs outside information or stronger remote reasoning. Perplexity says the user is asked for permission before device content is sent to a cloud service.
06
Connectors and external apps
Perplexity lists integrations including Google Drive, Gmail, Slack and GitHub. These connectors let a workflow combine local context with app data, subject to the permissions and authorization required by each service.
Use the minimum permissions needed for a workflow, especially when the local files contain confidential business material or private code.
07
Does local work consume Perplexity credits?
Perplexity says work handled locally does not consume credits. That can make repetitive or context-heavy workloads more practical on owned hardware, but it does not mean the product has no cost: launch access requires eligible Pro or Max membership and supported NVIDIA hardware.
Perplexity’s launch material does not publish a separate standalone Portable Computer price or a universal quota schedule, so a precise additional pricing table should not be fabricated.
08
How to get started on DGX Spark
Perplexity says eligible DGX Spark users can use a one-click installation flow through the Perplexity app. For the practical validation sequence, see how to install and use Portable Computer on DGX Spark.
09
Bottom line
Portable Computer is a hybrid local/cloud agent architecture. It now supports NVIDIA DGX Spark plus supported Windows and Linux RTX PCs with 24GB+ VRAM. Windows and Linux RTX PCs use PPLX 27B locally; Qwen 3.8 27B remains available on DGX Spark but not RTX PCs, while Nemotron 3.5 Lightning is still announced as coming soon.
