Portable Computer runs the agent's control plane on device and charges only when a task goes to the cloud. The part that decides when that happens is also the part nobody has priced or locked down.

The billing meter and the security boundary are the same event. Perplexity charges only when the system is explicitly told to move compute to the cloud for more advanced research and reasoning [5], so escalation is the revenue moment. It is also the moment several of the consultants quoted by Computerworld say has not been explained: users may click through an approval pop-up the way they click through terms and conditions, or hidden instructions could push a task outward without the user knowing [11]. A meter that runs only on escalation does not reward making escalation harder.
Justin Greis of Acceligence put the gap in governance terms, arguing that local-first should not be confused with local-only and that an enterprise needs the ability to say "you are not permitted to ask" [12]. Mike Wilkes of Aikido Security described the blunt fix, cutting external network access, and doubted anyone would accept it, since for many valuable use cases connectivity is the point [13]. Perplexity's own example concedes as much: a term sheet stays local while the system fetches market comps from outside [7], and the connectors reach Google Drive, Gmail, Slack and GitHub [6].
Free local inference still has a bill, just in a different column. Flavio Villanustre, CISO at LexisNexis Risk Solutions Group, put the floor at a local GPU with at least 24GB of VRAM and said the offering requires an initial investment in specialised hardware even if it lowers ongoing expenses [10]. Nader Henein of Gartner noted that the announced models already run on high-end laptops with off-the-shelf GPUs, and that without a published price it is hard to get excited [9]. Zero for local work, an unpublished software price, and a mandatory GPU purchase do not add up to a cost per task anyone outside the company can compute [14].
What is actually new here is narrower than the pitch and more interesting. Aman Mahapatra of Tribeca Softtech said running a model locally has been table stakes for two years, and that the change is running the whole agentic control plane on device, so the decision about whether a task needs the cloud is itself made locally by a model post-trained to keep work local [8]. That matches what ships: orchestrator, planner, tool router, scheduler, durable task queue and local search index all on device [3]. The weights are not the moat. The router is, and today it runs on Linux only, with Windows promised later [4].
Ranked by verification strength, evidence, and original report placement.
The local orchestrator can escalate a task to the cloud for current information, browser use, connected apps, or one of 15+ frontier models, and app connectors cover Google Drive, Gmail, Slack and GitHub.
Multiple consultants raised concerns about the lack of detail on how local-versus-cloud decisions are enforced, including users reflexively approving a cloud-compute pop-up and an attacker using prompt engineering or hidden commands to move work to the cloud without the user knowing.
Perplexity on Tuesday rolled out Portable Computer, an offering that runs the AI entirely on a local machine and, it said, keeps private data local, escalating to the cloud only when a task needs it.
Portable Computer is a local version of Perplexity Computer that runs on the Nvidia DGX Spark with Qwen 3.8 27B or with PPLX 27B, a post-trained version of the Qwen model.
Perplexity said a 30B open model is coming soon to the model picker.
The orchestrator, planner, tool router, scheduler, durable task queue and local search index all run on device.

Evidence-backed comparisons of source perspectives and observed adoption signals. Read the methodology
Which Builder, Operator, and Investor concerns the observed source mix emphasized—not a truth score.
Evidence, demonstrated adoption, hype gap, incentives, and confidence are assessed independently, each on its own current evidence. How these are measured.
Vendor announcement plus named expert critique, no independent testing
Product facts trace to Perplexity's own announcement as relayed by one trade publication; the critical material is on-the-record analysis from five named practitioners (Gartner, two CISOs, two consultancies) rather than measurement. No hands-on test, benchmark, price sheet or vendor answer to the central governance question is present, and the cluster has a single publisher.
Launch announced, no deployments disclosed
The only observable adoption events are the release itself and its zero-credit local billing disclosure, both dated to the announcement. No customers, pilots, install counts or usage data appear, and availability is narrowed by a Linux-only requirement, DGX Spark dependence and a 24GB VRAM floor.
Privacy and cost promises outrun the disclosed controls and pricing
The offering is marketed on data staying local and on paying nothing for local work, yet the mechanism that decides what leaves the device is a consent prompt with no enforced egress proxy, DLP, deterministic classification or audit logging, and no price has been published while a real hardware outlay is required. The reporting itself carries the counterweight, so the gap sits in the vendor framing rather than in the coverage.
Vendor launch narrative plus commercially interested commentators
Product facts originate in a Perplexity announcement promoting a privacy and cost advantage. The critical voices are credible but not disinterested: a Gartner analyst, two consultancy executives who sell AI advisory work, and CISOs including one at a security vendor whose market is exactly the egress and agent-governance gap being described. The article is also written for an enterprise IT trade audience where vendor launch coverage is routine.
Facts well attributed but single-publisher and unpriced
Attribution is strong within one article - direct quotes, named roles, explicit vendor language - so the claims are reliably characterized. Confidence is capped by having a single publisher, no corroborating coverage, no independent verification of the on-device architecture or model quality, and no price, which leaves both the security and economic conclusions provisional.
