Perplexity Launches Local-First Portable Computer Agent Stack with NVIDIA DGX Spark

On August 25, Perplexity announced that its "Portable Computer" feature is rolling out to all Pro and Max subscribers, built in partnership with NVIDIA as a local-first Agent stack optimized for the NVIDIA DGX Spark. The key point isn't just running models locally, but localizing the entire Agent stack: it supports one-click local inference setup and can run orchestrators and sub-agents on-device.Confirmed

• The feature is available now for Pro and Max subscribers, integrated with NVIDIA DGX Spark
• Available models include Perplexity's own post-trained PPLX 27B and Qwen 3.8B
• Perplexity CEO AravSrinivas demoed a fully local Agent runtime based on the 27B MoE: the cloud-based Computer Harness was adapted into a local-first version orchestrated by the local 27B MoE model running on DGX Spark, showing how progress in open-source models enables fully local Agents
• According to technical details relayed by ryanshrout, on the question of how the local 27B model decides when to call a frontier model, the orchestrator uses deterministic code rather than an LLM, so escalation decisions don't depend on the model itselfWhy it matters

This is a major player's attempt to push the entire Agent capability stack down to local hardware: with DGX Spark plus open-source and in-house small models, users can run Agent orchestration without any cloud dependency, while a deterministic orchestrator handles the problem of judging the capability boundaries of small models.
