Perplexity's Portable Computer tackling local AI services market

Now Perplexity is trying to get into the local AI action Amid talk of an Nvidia deal, the AI search biz is looking beyond the cloud Thomas Claburn Thomas Claburn AI AND SOFTWARE REPORTER Published wed 26 Aug 2026 // 00:39 UTC MOST POPULAR security Security vets rally around $4 paper password books for sale in Australia DEVOPS How Cursor beat Git's scalability shortcomings Security AliExpress accused of fingerprinting shoppers with silent audio trick that also muted a dev's headphones SAAS Salesforce partners not seeing meaningful revenue from Agentforce AI platform, report says PERSONAL TECH Casio decides it's about time the simple digital watch got a little smarter AI company Perplexity has already tried its hand at search services, advertising, personal assistants, browsers, and a hosted agent platform – and now it's getting into local AI services. The biz, having already built a hybrid agent inference orchestrator that connects cloud and local inference, has crossed that bridge to build a local agent called Portable Computer. That's in contrast to its cloud-based agent platform, Computer. Portable Computer consists of an agent harness, an orchestrator, and local AI models running on an Nvidia DGX Spark workstation, with the ability to tap into cloud inference if the situation demands. REG AD What's Nvidia DGX Spark doing there? Well, apart from the fact that DGX Spark is a capable bit of AI kit, Nvidia is said to be contemplating a $30 billion investment in Perplexity. Maybe, just maybe, that has something to do with six brand name mentions in one announcement. REG AD Perplexity casts its Portable Computer as a way to control AI costs, an issue of interest over the last few months as users find locally run open weight models may offer relief from bulging cloud bills. "Progress is most visible in very small and efficient models such as Nvidia Nemotron 3.5 Lightning (30B total parameters), Qwen 3.6 (35B), and Qwen 3.8 (27B)," the biz said in its post, paying somewhat more attention to Nvidia's model than other local AI enthusiasts. "These small models punch above their weight and are now capable of complex agentic workflows." What hardware might one run such models on? It may just be coincidence but Perplexity suggests Nvidia DGX Spark. "This local-first approach enables significant cost savings, since local inference avoids per-token API fees," Perplexity said. "It also naturally resolves the privacy and intellectual-property concerns: private tokens never need to be transmitted to remote clusters and remain safely within the boundary of the local device." A webmail interface displays multiple messages, illustrating the browser-based tasks Perplexity says its Portable Computer agent can handle locally. Perplexity's current privacy policy doesn't specifically mention Portable Computer, but does reveal that Perplexity collects quite a bit of data through its other services. Most of Perplexity's pitch to potential customers involves sharing benchmark results that compare Portable Computer to two other agent harnesses, Pi and Hermes. The AI biz reports, "Across the various benchmarks, Computer matched or exceeded Hermes and Pi in accuracy while running Qwen 3.8 27B on an NVIDIA DGX Spark." And Portable Computer, Perplexity claims, proved fastest on BrowseComp and ParseBench-100 and used the fewest tokens on all three. The AI biz concludes that a decent open-weight model and capable local hardware, together with a suitable harness, "can handle real knowledge work at near-zero inference cost without requiring sensitive data to leave the device." REG AD And in the event Nvidia does invest $30 billion, Perplexity will have plenty of time to explore how much it can charge in a market where harnesses like Pi and Hermes are free. ®
