Perplexity Ships Portable Computer on NVIDIA DGX Spark: Local Harness, OS-Enforced Sandbox, and Zero Per-Token Cost for Local Steps
Perplexity has released Portable Computer, a local-first build of its agentic Computer platform that runs the agent harness, orchestrator, planner, tool router and post-trained models directly on NVIDIA DGX Spark. The local model, inference engine, tool sandbox and app connectors ship as one packaged system, every task begins on the device, and work handled by local models carries no per-token charge. When a step needs the live web or frontier reasoning, the orchestrator stops and asks before s
Perplexity has released Portable Computer, a system that runs AI agent software directly on local NVIDIA hardware rather than relying on cloud servers. The system includes a local model, inference engine, orchestrator, and security sandbox, with tasks processed locally at no per-token cost, though steps requiring live web access or advanced reasoning require explicit user approval before sending to cloud models. This matters for organizations in finance, legal, healthcare, and government where data residency rules or confidentiality requirements prevent sending information to cloud services. The system requires significant hardware investment, starting with either a GB10-class NVIDIA box or an RTX GPU with 24 GB of VRAM, making it viable only for enterprises and well-funded startups rather than general small businesses.

AI agents carry memory and storage like people, so their data needs guarding while in use
As AI agents move into production on Kubernetes, cloud engineering teams at financial companies face a security problem that encryption alone can’t solve. Container orchestration has become the default foundation for AI workloads, and the data those agents use is now the main target. Payment networks feel that pressure more than most because every transaction […] The post AI agents carry memory and storage like people, so their data needs guarding while in use appeared first on Silic
